Technical details
Vacuum furnace for tempering and hardening steel - model Quantum G, Type HVF 60/60/100- 12.01QP, with gas cooling at a pressure of 12 BAR, prepared for NITRO-TOOL nitriding and PIRO-CARB vacuum carburizing technology, together with the necessary equipment.
The hardening and tempering furnace is used for heat treatment of high-alloy tool steels and carbon steels. This is a device that allows you to significantly increase the service life of tools. A vacuum tempering and hardening furnace is needed to fully utilize the technological capabilities of the Anca tool sharpener. Increasing the service life of steel tools several times will significantly reduce the plant's operating costs.
