1、spindle:The spindle is structured with high-power,large-torque,and high-precision sleeve,characterized by increased reduction ratio and good low-speed performance.
2、Turret:The servo turret is configured with the servo motor indexing,crankset positioning and hydraulic clamping mechanisms,or a traditional servo turret is used.
3、X/Z-axis:It is driven by a high-grade imported precision ball screw with the roller guide widened and span increased,thereby with standing heavy cutting.
4、Tailstock:Adopt a tailstock of high rigidity and mountain-typed flat guide rail for easy movement.
