Knife tower machine series

● Resin sand casting, not easy to deformation, precision long-term stability, reinforced steel structure, with high rigidity and excellent earthquake resistance; ● Main shaft herringbone design, stable structure, strong rigidity, suitable for strong cutting; ●X ,Z axis are supported by C3 class ball screw and Japanese P4 class ball bearing to improve the machining accuracy. Using linear slide rail, track and track to obtain the optimal span, instead of resistance, high rigidity, fast displacement degree; ● Fully enclosed cover, high speed, high water cutting; ● Optional power turret, with 0 or 90 degree power head, turning and milling once; ● It can be equipped with automatic chip evacuation machine for self-chip removal, easy to clean.

▌ Processing application

Free cutting steel, tool steel, brass, ball bearing steel, stainless steel, aviation aluminum.
