GRINDING & POLISHING
What we can do
Internal and external cylindrical grinding and surface grinding. We can reach Ø600 cylindrical grinding with a length of 4,000 mm between the centres. For a finer finish after grinding, we can polish and super-finish to very fine surface roughness and minimal shape tolerances.
Precision finishing with very high accuracy in measurements, geometry and run-out. Final processing to the desired roughness profile (BAC curve) and extremely low Ra values (in function of the material and coating, Ra values <0.005 μm are possible).
For new parts
Manufacturing of precision parts with minimum tolerances and run-out. Critical parts with tungsten carbide coatings are pre-ground with attention to homogeneous layer thickness and surface profile. Treatment of hardened materials and HVOF sprayed tungsten carbide coatings.
Removal of hard coatings and pre-treatment for repair of critical parts. Final processing and in-line polishing of repaired parts by means of thermal metal spraying. Finishing within the size and shape tolerances and to the required surface roughness.
