BXA20 – Automotive Part – BXA20


Longer tool life- In turning on inner spherical surface, the competitor’s tool life ends after machining 750pcs/corner due to sudden fracture caused by impacts in interrupted machining.- BXA20 with high toughness achieves 1000pcs/corner, 1.4 times more than the competitor, without a fracture.
