Why are Hardinge lathes ideal for Hard Turning?
What is Hard Turning? What Hardness ranges are appropriate for Hard Turning? Hard turning is defined as the process of single point cutting of part pieces that have hardness values over 45 Rc. Typically, however, hard turned part pieces will be found to lie within the range of 58-68 Rc. The approach to machining hardened steel depends on the degree of hardness and its depth (if case hardened). The hard turning process is similar enough to conventional “soft” turning that the introduction of this process into the normal factory environment can happen with relatively small operational changes when the proper elements have been addressed.
