The strength of the roller material, the hardness of the ordinary carbide tools has been the strength and hardness

The strength of the roller material, the hardness of the ordinary carbide tools has been the strength and hardness, and therefore can not properly ordinary cutting tool, although the process can be appropriate to reduce the hardness of the quenched and tempered, easy machining, but it cost too grinding wheel period, therefore chose to cast direct processing. Through a variety of high hardness tool (including ceramics tools and import tool) and repeated trial-parallel comparison, the best selection of hardness and wear resistance are in line with the requirements of superhard cutting tools and polycrystalline diamond heads for efficient turning , higher labor costs in the current circumstances, is more suitable for mass production using CNC machine tools. Particularly for the use to be repaired after the rollers, since the use of the process is equivalent to a work hardening and hardening times, ultra-high hardness, can not be cut in the case, we use the tool to repair hard machining grades, the effect is very good .
