Cylindrical grinding
What is cylindrical grinding?
Cylindrical grinding is an essential finishing machining process for achieving perfectly cylindrical geometries with very tight dimensional tolerances. This technology allows for micron-level precision and ensures extremely fine surface finishes.
Equipped with high-performance cylindrical grinding machines, we perform internal and external grinding operations on small to medium production runs.
Our machine park allows us to guarantee rigidity, thermal stability, and repeatable precision. These characteristics ensure consistent quality, even when machining complex materials such as hardened steels, stainless steels, or superalloys. This performance is supported by a team that can be adjusted according to production needs.

Advantages of cylindrical grinding:
- Enables high dimensional accuracy (tight tolerances)
- Ensures excellent surface quality.
- Applies to external cylindrical surfaces (shafts, axles, cams) or internal cylindrical surfaces (bores)
Areas of application:
Cylindrical grinding is widely used in the following sectors:
- Aerospace: engine parts, drive shafts, turbine shafts, ball cages;
- Automotive: crankshafts, camshafts, piston pins;
- Mechanical engineering: bearings, bushings, sleeves, punches/dies, spindles, precision tools;
- Defense: artillery parts
