Grinding

Grinding process is carried out on the basis of the newest generation of grinding machine for shafts and holes by STUDER and for longer lengths on conventional grinding machines. Before grinding process the details are normally are subject to heat treatment processes such as carburization or hardening for hardness required by the customer. For the production of manifold blocks and plates we perform the surface grinding process.

Range of grinded dimensions:

• Internal diameters: 2-300mm;

• External diameters: 2-250mm;

• Length of grinded details externally up to 1000mm.

• Surface grinding regarding dimensions 500 x 200 x 200

Grinded elements have cylindricity between 0,002-0,01 depending on the diameter and length of grinded element and surface class Ra ≤0,32. In view of the complex process of production: turning heat treatment process, grinding, measurement, protection of grinded surface for transport of the parts for diameters less than ø-40 we prefer production series more than 1000 pieces. With such a serial production we believe that we are competitive.

For larger diameter and longer parts we are already competitive for small and middle production series. We grind, among others, piston rodes for hydraulic cylinders.
