New website for Micro Mécanique

Bryan Parmentelot — Tue, 21 Apr 2026 14:00:53 +0000

New interface, smoother navigation, and a stronger showcase of achievements: MicroMécanique unveils a redesigned website that reflects the level of precision and attention to detail driving the team every day.

Contents

MicroMécanique: at the heart of the new website

The new MicroMécanique website has been designed to make visible what is not always seen with the naked eye: precision micromechanics, those tight tolerances and flawless surface finishes that make all the difference for a part, a subassembly, or a device. The redesign focuses on a simple promise: get straight to the point, quickly understand the workshop’s capabilities, and obtain a clear answer to a concrete need.

Why a new website? Clearer, more useful

In an industrial environment where everything is accelerating, a website is the first interface with your purchasing, methods, or quality teams. We therefore prioritized:

simplified navigation by type of need (prototyping, small/medium series, re-machining),
concise expertise pages detailing dimensional ranges, commonly machined materials, and typical tolerances achieved,
concrete examples from production to help you visualize in seconds.

Objective: save time for everyone, without unnecessary jargon—while showing the reality of the field.

What you will find on the new platform

Expertise presented through technical challenges

Micromechanics is now presented through real production situations: thin and fragile parts, micro-drilling, demanding surface finishes, dimensional tolerances below one hundredth of a millimeter, small-scale assemblies, etc. Each section indicates when we are the right partner and how we approach each challenge.

Achievements to grasp at a glance

A “Projects” section showcases representative parts (dimensions, materials, quality challenges). The goal is not to create an exhaustive catalog, but to illustrate the variety of cases encountered in micromechanics.

A more direct contact journey

The form has been simplified: describe your need in a few lines, specify your target tolerances, attach technical files (drawings, 3D), and choose your preferred callback time slot.

A real workshop scenario: from need to final inspection

To illustrate the purpose of this redesign, here is a typical workshop scenario that guided the website structure.

Monday, 8:30 AM. A manufacturer of surgical instruments contacts us. They need a stainless steel micro-component with micro-drilling and controlled surface finish to ensure smooth motion. Inner diameter tolerances are below ±0.01 mm. The timeline is tight: a pilot batch is required within two weeks for clinical testing.

9:30 AM. Technical discussion with our methods specialist. We review the drawing, critical points, inspection methods, and the planned production chain (material cutting, machining, reworking, finishing, cleaning, final inspection). An initial process/quality proposal is sent. The client approves.

Day +2. The workshop launches prototyping. Tests focus on edge integrity, dimensional stability after finishing, and repeatability in inspection. A first compliant batch is produced, accompanied by metrology reports.

Following week. Delivery of the pilot batch, positive feedback: the part integrates perfectly with the client’s subassembly. This type of scenario—clear need, rapid iteration, rigorous inspection—inspired the new website: you will find this logic step by step.

Process and quality: rigor, traceability, responsiveness

Micromechanics requires daily discipline. Our process emphasizes:

Feasibility review: validation of requirements, analysis of critical points, selection of tools and processes.
Structured prototyping: short iterations, intermediate inspection, and tooling adjustments if needed.
Series production: stable settings, monitoring of potential deviations, and inspection records.
Metrology inspection: appropriate tools (probes, gauges, profile projectors, 3D inspection depending on the part), with measurement reports provided.
Traceability: material batches, key parameters, and inspection results linked to each project file.

This precision process is only valuable if it is clearly understood. Hence the importance of a website that clearly explains what we do and how far we can go, depending on materials (stainless steel, titanium, aluminum, technical polymers, brass…) and target dimensions.

Applications and industries served

Micromechanics expertise applies to various environments:

Medical / instrumentation: miniaturized components, high-quality finishes, controlled cleanliness depending on use.
Industry and robotics: guiding parts, spacers, precision elements for compact kinematics.
Watchmaking / microtechnologies: fine tolerances, consistent surface finishes, demanding small series.
Aerospace / onboard instrumentation: repeatability, dimensional stability, and documentation traceability.

The new website presents these sectors by needs (dimensional performance, finishing, miniaturization), making it easy for everyone to find their way.

How to navigate: 3 quick paths

1) You have a drawing and a deadline

Go to the “Contact” page to upload your drawing and specify your target tolerances. You will receive a structured response on feasibility and an estimated lead time.

2) You have an idea but no final drawing

The site explains how we co-develop the solution: sketches, technical discussions, and prototyping iterations to validate material choices and key dimensions.

3) You are looking for references and guarantees

The “Projects” section showcases real cases. You will see examples of parts, associated technical challenges, and inspection points carried out.

Want to learn more?

Discover the new MicroMécanique platform, designed for purchasing, methods, and quality managers who want to get straight to the point.

The launch of the new MicroMécanique website is more than just news: it is the digital translation of a daily standard of excellence. In micromechanics, every hundredth counts, and every step—from drawing review to final inspection—must be crystal clear. This redesign brings clarity, concrete examples, and fast navigation paths to accelerate your decisions. We hope this platform will save you time and give you a precise understanding of what we can achieve together.

Tungsten carbide machining

Over 80 years, MicroMécanique has forged unique expertise in tungsten carbide machining. This exceptionally hard material requires expert machining skills and specific state-of-the-art machinery. Our engaged, diligent staff produce micromechanical tools and parts with micron-level precision, capable of withstanding the most demanding industrial environments.

Tungsten carbide (chemical symbol WC) is a compound of carbon and tungsten. Tungsten has the highest melting point (3,422°C) of all metals, the lowest vapour pressure, and the greatest tensile strength at a temperature above 1,650°C. Derived from the old Swedish name for ‘heavy stone’, tungsten is mainly used in the engineering industry, mostly in compounds or alloys like tungsten carbide. Tungsten carbide parts are hard enough to withstand the many stresses of intensive production environments and must be machined with ceramic or diamond tools. Parts made from WC have a high compression strength and good wear and oxidation resistance at high temperatures. Our customers appreciate the quality of the tools we produce, as they last much longer than treated steel parts.

Properties of tungsten carbide

Extreme resistance to wear and abrasion.
Dimensional stability: very little thermal expansion.
High compression and tensile strength.
Optimal behaviour under harsh conditions (high temperature, corrosion).
Extends the lifespan of tools and components.

Hardened steel

Julien ROUSSEL — Tue, 03 Mar 2026 10:35:18 +0000

Machining of hardened steel

Hardened steel refers to alloyed or non-alloyed steels that have undergone heat treatment (quenching + possibly tempering) to increase their hardness and mechanical strength while maintaining a certain toughness. At MicroMécanique, we use hardened steel as a base technical material to produce demanding parts: tools, mechanical components subjected to high stress, guide systems, etc. We master not only the machining of hardened steel after treatment, but also other operations like finishing, grinding and polishing, with micron-level precision.

Examples of products and possible applications

Here are some examples of products MicroMécanique has the capability to develop or produce from hardened steel:

Transmission shafts, crankshafts and other shafts subjected to torsion and high mechanical stress.
Pinions, gears, machine teeth and gearbox parts
Drive parts, connecting rods, shafts and axles
Tooling: dies, moulds, impressions, tool plates and punches
Guide systems, rails, slides and precision components for special machines
Parts with tight tolerances for watchmaking, luxury goods or measuring instruments
Cylinder barrels, parts resistant to fatigue or mechanical wear.

Properties of hardened steel

Property	Description
Hardness	After quenching, hardened steel can reach a Rockwell hardness of around 50 to 65 HRC, depending on the grade and cross-section.
Tensile strength and yield strength	Very high, potentially exceeding 800 MPa depending on the alloy and treatment.
Toughness	Tempering reduces the brittleness caused by quenching and enables a suitable compromise between hardness and toughness.
Dimensional stability	Limited thermal expansion, stability at high temperatures, good resistance to temperature variations.
Wear resistance	Good resistance to abrasion and friction, especially with precise finishes or additional surface treatments (coating, nitriding, etc.).
Fatigue resistance	This is important, especially for parts subjected to load cycles: hardened steel alloys with good tempering and surface treatments can improve fatigue resistance.
Hardenability	This depends on the chemical composition (carbon content, alloy elements) and the cross-section of the part: the thicker the cross-section, the better the alloys must be designed to ensure consistent hardness throughout.

Machining techniques we use (or can use) at MicroMécanique

Below are the processes that MicroMécanique offers and can offer for hardened steel, by achieving the relevant technical feats:

5-axis/multi-axis high-speed machining (HSM) for certain complex parts, particularly when conventional machines have limitations when it comes to complex designs. Our machines are also equipped with a grinding module.
Wire and spark EDM
CNC milling/turning: direct machining of hardened steels, often replacing or reducing the need for grinding. Very useful for reducing cycle times.
Surface and cylindrical grinding: to achieve high-precision surfaces, very smooth finishes and tight tolerances.
Microdrilling and drilling in hardened steel: demanding in terms of tools (very hard inserts or tools, often coated, sometimes CBN) and cutting parameters (low speeds, generous lubrication).

Would you like to work with hardened steel?
Discover its applications

Sectors in which hardened steel is particularly useful, and where MicroMécanique can add significant value:

Aeronautics and space: structural parts, shafts, gears, guide systems, where weight, strength, tolerances, lifespan and safety are critical.

Ceramics

Julien ROUSSEL — Tue, 03 Mar 2026 10:34:50 +0000

Ceramic machining

MicroMécanique has advanced capabilities for machining technical ceramics: silicon nitride (Si₃N₄), alumina (aluminium oxide, Al₂O₃), zirconia (zirconium oxide, ZrO₂) and ceramics that can be machined by electrical discharge machining (EDM). These materials are chosen for their exceptional properties: low density, high hardness, resistance to high temperatures and corrosion. They are particularly suited to precision applications in harsh environments, especially when metals or alloys reach their limits.

Examples of products and applications

Here is what MicroMécanique could or can already achieve with these ceramics:

Insulators or supporting elements for motors or turbines exposed to high temperatures.
Bearing parts, balls, rods, pins requiring hardness, wear resistance and inertia.
Components for the chemical or biochemical industry: nozzles, rings, membranes, parts in contact with corrosive environments or abrasive materials.
Optical or precision components: substrates, guides, components for measuring or optoelectronic instruments.
Inserts or plates in moulds and dies for heavy-duty use (wear/abrasion).
Components for power electronics, sensors and probes, where electrical insulation and thermal resistance are required.
Prototypes or small series for watchmaking, luxury goods and medical devices requiring a high-quality finish.

Properties of technical ceramics (Si₃N₄, Al₂O₃ and ZrO₂)

Property	Description/Values
Density	Relatively low compared to hard metals; typically ~3.9-4.1 g/cm³ for alumina, higher for zirconia depending on the formulation, around 3.2-3.4 g/cm³ for Si₃N₄.
Hardness	Very high: Al₂O₃ and ZrO₂ are particularly hard ceramics. Si₃N₄ is very hard but also tougher.
Heat and thermal shock resistance	Si₃N₄ is distinguished by its extreme thermal shock resistance, which it retains even at high temperatures, as does ZrO₂, depending on its stabiliser (yttria, etc.).
Low coefficient of thermal expansion	Particularly Si₃N₄, which results in good dimensional stability during heating and cooling.
Corrosion and wear resistance	Ceramics are chemically inert in many environments and very resistant to abrasion.
High rigidity and tensile strength	Good stiffness, high Young’s modulus, but low ductility (brittle if poorly designed or treated).
Electrical insulation	Alumina, zirconia and Si₃N₄ are good electrical insulators in most configurations.

Machining techniques used at MicroMécanique

The following relevant machining processes are used for ceramics and adapted to MicroMécanique’s capabilities:

High-speed machining, CNC and conventional mechanical machining: turning, milling, drilling (with diamond tools, or extremely hardwearing tools), for pre-hardened and densified parts.
Grinding and abrasive machining: to obtain highly polished surfaces with tight tolerances. Use of diamond grinding wheels with very fine grits.
Microdrilling and micromachining: for very small holes and intricate geometries.
Ultrasound: machining with abrasives and ultrasonic vibration for brittle ceramics, to avoid cracking and minimise mechanical stress.
Electrical discharge machining (EDM) for conductive or modified ceramics, or for materials for which EDM is possible. Enables complex shapes and intricate geometries without direct mechanical contact. XXX
Polishing, tribofinishing, very fine finishes, possibly post-machining treatments to improve strength or appearance.

Titanium

Julien ROUSSEL — Tue, 03 Mar 2026 10:30:56 +0000

Titanium machining

Titanium is a lightweight metal with a very high strength-to-weight ratio, renowned for its rare combination of properties: high mechanical strength, excellent corrosion resistance, good biocompatibility and high-temperature stability. Titanium alloys (such as Ti-6Al-4V, α, β or α-β alloys) are used in demanding industries (aeronautics, medical equipment and space). At MicroMécanique, we are accustomed to the challenges of working with titanium and its alloys, and we have machinery capable of producing precision parts, prototypes or small series.

Examples of products and possible applications

Here is what MicroMécanique could or can already achieve with titanium:

Aeronautical and space components: supports, structural elements, lightweight parts and engine or turbine components.
Medical implants (orthopaedics, dentistry), surgical instruments and biocompatible parts.
Chemical and marine industry parts exposed to corrosive or aggressive environments.
Components requiring a good strength-to-weight ratio: reduced weight, moving parts and precision mounting components.
Prototypes, small series for luxury goods or watchmaking, where finish, appearance and resistance are key.
Parts subjected to high temperatures or thermal shocks.

Properties of titanium and its alloys

Property	Description/Typical values
Density	Around 4.5 g/cm³ for commonly used alloys (much lighter than steel or tungsten).
Mechanical strength/yield strength	Depends on the alloy, for example Ti-6Al-4V has high tensile strength and offers an excellent compromise between strength and weight.
Young’s tensile modulus	Around 110-120 GPa for pure titanium/alpha-beta alloys.
Hardness	Depends on the alloy: some alloys can reach ~30-40 HRC depending on treatment.
Thermal conductivity	Low: titanium is a poor heat conductor, which poses challenges during machining (the heat concentrates on the tool).
Corrosion resistance	Very good: a passive layer of titanium oxide is formed, which protects against harsh conditions (seawater, weak acids, etc.).
High-temperature resistance/thermal stability	Titanium alloys retain good mechanical properties at high temperatures, but there are limitations depending on the alloy.
Biocompatibility	Very good for medical uses – pure titanium or specialty alloys are widely used for implants.

Machining techniques required/used at MicroMécanique

Working with titanium and its alloys requires appropriate processes, tools and machines. MicroMécanique uses the following:

Specialised CNC turning/milling: very sharp tools, appropriate angles and appropriate feed rates to avoid vibration and adhesion.
5-axis machining and high-speed machining for complex workpieces, curved surfaces and difficult geometries.
Internal cooling and high lubrication: we use high-quality cutting fluids and in many cases internal or external cooling to efficiently remove heat.
Moderate cutting speeds but appropriate feed rates and depths: we avoid excessive speeds and favour strategies that reduce heating.
Coated carbide tools or special inserts: heat/wear-resistant coatings such as TiAlN to extend tool life.
Vibration/buckling control on thin sections: high-quality fastenings, rigid machines and toolpaths designed to avoid vibrations.
Surface treatments after machining: polishing, passivation (controlled oxidation) and possibly heat or other treatments depending on use (medical, aeronautics).
Strict measurements and quality control: tight tolerances, surface finishes, precise geometry and traceability.

Stainless steel

Julien ROUSSEL — Tue, 03 Mar 2026 10:27:45 +0000

Stainless steel machining

Stainless steel is an iron alloy primarily enriched with chromium (≥11-12%) to form a passive corrosion-resistant layer. Depending on the alloy (austenitic, ferritic, martensitic, duplex, etc.), its properties vary greatly (hardness, temperature resistance, formability). At MicroMécanique, stainless steel is a technical material that we use for parts requiring corrosion resistance, high mechanical strength and precision finishes.

Examples of products and possible applications

MicroMécanique has the capability to use stainless steel to make the following parts and applications:

Parts in contact with corrosive environments: flanges, rings, seals, pump components and piping.
Food industry or pharmaceutical industry components requiring cleaning and sterilisation, and subject to specific health standards.
Medical device parts, surgical instruments, external implants or instruments.
Structural or fastening parts in the chemical, oil and marine industries (screws, brackets, flanges).
Tooling, dies and inserts subjected to mechanical stress and corrosion.
Bearings, axles, guide systems in special machines where durability, finish and resistance to the environment are key.
Prototypes and small series for watchmaking or luxury goods when decorative stainless steel or a visible stainless steel finish is desired.

Property	Description/Typical values
Corrosion resistance	Excellent in many environments: atmospheric, fresh water, acid/alkaline media depending on the grade. The addition of molybdenum, nickel and nitride improves pitting or crevice corrosion.
Density	Around 8.00 g/cm³ for grades like 304.
Melting point/heat resistance	Stainless steel melts at around 1,400-1,530°C depending on the alloy. It has good mechanical strength at moderate temperatures (used hot, but with limitations).
Modulus of elasticity	~ 193 GPa for 304; quite high, good rigidity.
Elongation/ductility	Austenitic grades (304, 316, etc.) have very good ductility (e.g. ~45% elongation for 304).
Hardness/mechanical strength	Varies greatly depending on the grade and state: some martensitic or duplex grades can achieve significant hardness but are often more difficult to machine. For example, 440C (a martensitic stainless steel) reaches ~58-60 HRC with certain treatments.
Thermal conductivity and thermal expansion	Low to moderate thermal conductivity; fairly significant thermal expansion for austenitic grades. This can pose a problem for dimensional stability at high temperatures.

Machining technologies that MicroMécanique uses or can use

Machining stainless steel has its challenges: it hardens when cut, has low thermal conductivity and a tendency to adhere to the tool. MicroMécanique applies the following techniques:

CNC turning/milling: with heavily coated tools, suitable inserts, optimal sharpening, moderate cutting speeds, appropriate feed rates and effective lubrication.
Grinding/polishing: for high-quality surface finishes, aesthetic or functional finishes, and tight tolerances.
Stainless steel microdrilling and drilling: require wear-resistant tools, good cooling and chip control to avoid clogging or localised overheating.
5-axis milling and high-speed machining for complex workpieces, curved surfaces and difficult geometries.
Heat treatments for martensitic or duplex grades: quenching, tempering or annealing to adjust hardness/toughness.
Cutting and rough preparation: laser cutting, waterjet cutting, etc., for blanks before finishing.
Surface treatments: polishing, brushing, passivation, possibly non-stick treatments and decorative treatments.
Meticulous quality control: geometric tolerances, surface finish, absence of cracks and traceability.

Inconel®

Julien ROUSSEL — Tue, 03 Mar 2026 10:15:06 +0000

Inconel® machining

Inconel^® refers to a family of nickel-chromium-based superalloys renowned for their excellent resistance to high temperatures, oxidation and corrosion. These alloys retain their mechanical properties under extreme conditions, making them vital for critical applications (such as in the aeronautics, space, nuclear and chemical industries). At MicroMécanique, our expertise in Inconel^® machining allows us to offer high-performance parts that combine strength, longevity and precision and that are compatible with harsh environments.

Examples of products and possible applications

Below are some examples of parts that MicroMécanique can produce with Inconel^®:

Turbines, discs, blades or components of turbine engines or jet engines exposed to high temperatures.
Combustion parts, combustion chamber components and exhaust ducts.
Flanges, seals, valve stems, oil and gas well components subject to corrosion/heat.
Equipment for the chemical industry, reactors, heat exchangers, supports or surfaces exposed to corrosive or oxidising environments.
Parts for nuclear power plants, steam generators and piping components with stringent thermal/radiation protection requirements.
Components for space or launch vehicles, where thermal loads, temperature cycles and creep are critical parameters.
Tools subjected to high temperatures or oxidation (special moulds, inserts, forgings, etc.).
Prototypes and small series for specialised sectors (aeronautics, defence or research) requiring high-performance alloys.

Properties of Inconel® (and common alloys such as 625, 718 and 600)

Property	Description/Technical data
High-temperature resistance	Inconel^® retains its mechanical properties (strength, creep) at temperatures where many standard metals are weakened.
Oxidation and corrosion resistance	Very good, even in oxidising or aggressive environments. The alloy forms protective oxide layers. Excellent resistance in corrosive or high-temperature atmospheres.
Mechanical strength/fatigue resistance	Good tensile strength, resistance to thermal and mechanical fatigue. Alloys like Inconel^® 718 or 625 are often used for their durability under high stress and thermal cycling.
Creep behaviour	Very good, which is vital for parts exposed to high temperatures and sustained or variable loads.
Low thermal conductivity	Inconel^® has relatively low thermal conductivity, which means that the heat generated during machining remains more concentrated and appropriate methods are needed to dissipate it.
Tendency to work-harden (cutting heats and hardens the workpiece)	During successive passes, the alloy hardens rapidly, which can make subsequent passes more difficult.
Composition/representative grades	Some common alloys: Inconel 600, 625, 718, X-750, etc. Each one has its advantages (corrosion resistance, weldability, high-temperature resistance).

Machining techniques required/used at MicroMécanique

At MicroMécanique, we machine Inconel^®using the following methods, to guarantee the highest quality:

CNC milling/turning: using very hard inserts and suitable coatings (e.g., TiAlN and ceramic) to resist heat and abrasion. It is vital to limit vibration, tighten the tool securely and use robust machines.
Fewer passes and an appropriate feed rate: avoiding overly aggressive deep passes to limit excess heat and local hardening.
Substantial cooling/lubrication: efficient cutting fluid systems, possibly internal cooling, use of specialised lubricants or additives for Inconel^®.

Grinding and polishing: to obtain precise finishes after machining, especially for parts subject to fatigue or thermal cycling.
Electrical discharge machining (EDM): for certain shapes, complex geometries or hard-to-access surfaces, or very small internal drilling.
Machining after annealing/solution heat treatment: to improve machinability, then a final heat treatment if necessary to achieve the final properties.
Strict dimensional controls: tight tolerances, monitoring distortion, inspecting finishes, flatness or concentricity, etc.
