Introducing examples of direct engraving processing on hardened steel! Achieving a uniform finish without variation in depth dimensions through high-speed, long-duration processing!
We would like to introduce an example of direct engraving processing of hardened steel made by the machining machine "CEGA-542 (Roku-Roku)" with a performance of max 30,000 min-1. After uniformly machining the flat surface with a CBN ball end mill, it is finished at depths of 0.003 mm for the upper section, 0.006 mm for the middle section, and 0.009 mm for the lower section, with a pitch of 0.003 mm. Even with high-speed and long-duration machining, it is finished uniformly without variation in depth dimensions. 【Example】 ■ Material: STAVAX (HRC 52) ■ Machining size: 120 × 60 × 6 mm *For more details, please refer to the PDF document or feel free to contact us.
