Reliable machine frame provides more possibilities.
Heat treatment is a specialize process that requires experience, expertise and the right equipment. Heating processes such as annealing and stress relieving remove the inherent stress properties in steel, improve the machine-ability, and allows us to grind parts to higher flatness standards. The machine frame enters stationary annealing furnaces for stress relieving and annealing process over 12h, this is the reason why Han's basic frame last long and quality guaranteed.
