Česká zbrojovka a.s. manufactures and supplies to its customers engineering products, parts and assemblies designed mainly for aircraft and automotive industries. The automotive industry includes activities such as machining, stamping, degreasing and control of production. All of these activities possess certificates. The aircraft industry is involved in production of gear-units for motors and gear wheels, further there are tool works involved in sharpening and in production of cutting tools, gauges, fixtures and moulds. As the surface finishes are concerned we make blueing, phosphating, chromium-plating, nickel-plating and painting. Among heat treatment operations we do hardening, carburising, annealing and blasting.
Blackening Phosphating Chroming Nickel-plating Painting
Heat treatment is performed in a computer-controlled furnace. Degreasing of parts prior to hardening is carried out in tri-chlor vapours in a facility with a closed cycle. For all processed parts there is an attest certificate in respect of the hardness test; archiving takes place automatically during the cycle. On request, there is the possibility of conduction metallographic analysis, and/or issuance of a document concerning the heat treatment process.
Heat treatment by hardening, tempering and annealing of structural and tool steels in a vacuum.
Limitations to the size and weight of the processed parts:
Heat treatment by hardening, tempering and annealing of structural and tool steels in a protective atmosphere.
