Grinding is one of MicroMécanique’s long-standing areas of expertise. This process produces surface finishes of exceptional quality and micron-level precision, both on flat surfaces and on internal or external cylindrical surfaces.
This finishing technique is vital for achieving perfect geometry, dimensional accuracy and long-lasting components, especially for hard materials like tungsten carbide and hardened steels.
Direct industrial applications
Surface and cylindrical grinding is used for:
- Aeronautics, space and defence: for critical mechanical parts that must withstand extreme stress.
- Nuclear power and energy: for components subject to wear, requiring micron-level precision.
- Watchmaking and luxury goods: for perfect finishes on miniaturised and decorative parts.
- Medical devices and connectors: micron-level adjustments for specific fixtures and tools.
- Engineering and automotive: to produce complex cylindrical parts, shafts, rings and bushings.

Capabilities and performance on technical and hard materials
Our grinding machines allow for tolerances of ±0.001 mm and surface finishes up to Ra 0.005, even on the most complex materials:
- Tungsten carbide: to produce tools and wear parts with extreme precision.
- Hardened steels: for high-strength shafts, bushings and components.
- Titanium and superalloys: for complex parts requiring a perfect finish.
- Stainless steel, copper, brass and aluminium: for delicate grinding on technical or decorative parts.
- Industrial ceramics: for fragile components requiring micro-polishing and microfinishing.
Grinding, alongside turning, milling or 5-axis high-speed machining, is a vital part of the process we offer our customers to achieve dimensional and functional perfection.
