Wide range of 2, 3 and 5 axis high precision CNC machines of Japanese company MAZAK ensure best quality of compact parts as: pistons, cylinder heads (glands), cylinder bases (caps), integrated valve blocks, port blocks etc.

The deburring of sharp edges of the turned and milled parts of the details is of upmost importance for the upcoming stable work of the hydraulic cylinders. For this purpose, beside the usual washing machines, HES uses a TEM machine (thermal deburring) produced by KENNAMETAL Extrude Hone. The TEM process utilizes the combustion of methane gas within a pressurized chamber to remove burrs, flashings or hidden contaminants from machined components through an oxidation reaction.

The compact parts workshop, which is situated at a territory with an area of 5000 m2 contains also a fully automated system composed of: material warehouse, loading / unloading manipulator and band saw machines.
