Technical Features

• Adopts cyclone hard milling technology to ensure the surface hardness of the lead screw raceway.
• Uses indexable CBN inserts for high-speed milling, improving efficiency by 30% compared with traditional methods and reducing processing costs.
• Compressed cold air cooling reduces environmental pollution caused by coolant usage.
• Helix accuracy of the milled ball screw: 0.052 mm at any 300 mm measuring length.
• Lead screw diameter consistency error: 0.05 mm.
• Equipped with SIEMENS 828D CNC system enabling three-axis linkage control.

Controlled Axes

• Z-axis: Longitudinal movement of the table
• X-axis: Cross-feed movement of milling cutter frame
• C-axis: Headstock spindle rotary motion

Application: Mainly used for hard rotary milling of ball-screw thread raceways, and can also process trapezoidal screw threads.
