Advantages of tool vacuum heat treatment – heat treatment

Tool vacuum heat treatment technology has a series of outstanding advantages: the vacuum heat treatment has the anti-oxidation effect. Surface oxidation, decarbonization, and reduction cleaning, dispense tool roughing process, can save expensive tool steel and raw and auxiliary materials consumption, save processing time, reduce the product cost; Vacuum heat treatment with vacuum degassing, degreasing and no hydrogen embrittlement danger, to prevent the cutting tool material embrittlement of refractory metal surface, make the cutting tool material surface improve purity, improve tool fatigue strength, plasticity and toughness and corrosion resistance, prolong the service life of the tool.

Tool vacuum heat treatment quenching deformation is small, can reduce conventional quenching distortion correction of the stress, reduce the possibility of blade fracture in use process, vacuum heat treatment deformation of blade for 1/2-1/10 of the salt bath quenching, quenching after generally does not need correction can be fine grinding processing to finished product; The vacuum heat treatment process is stable and repeatable. Once the process is determined, the heat treatment operation will operate automatically as long as the process is entered. Avoid the fluctuation of tool quality caused by unstable heat treatment process; Vacuum heat treatment consumes less power, energy consumption is 80% of conventional heat treatment, production cost is low, but one-time investment cost is large; The vacuum heat treatment operation is safe, the automation level is high, the working environment is good, pollution-free and pollution-free, is in line with the requirements of the clean production and sustainable development of our industrial enterprises.
