Use Shenyang CAK50186 machine tool with GSK 980TDI system to process a slender shaft with a length of 1.5 meters and a diameter of 50;

There is no vibration during the processing, the surface texture of the workpiece is clear, the roughness is 3.2, and the straightness is 0.02mm;

It is processed and inspected according to the drawing size.

 

 

solution   

 

 

Clamping method: adopt one clamp, one top + follow tool holder;

Machine tool requirements: machine tool horizontal deviation ≤0.02mm, tailstock and spindle equal height deviation <0.05mm, tail top and workpiece contact surface 3mm or more;

Use high-quality tools for roughing first and then finishing to improve efficiency.

 

  Application effect

 

 

The outer circle of the workpiece is processed without vibration lines, the overall lines are clear and no chaotic lines, and the straightness is stable at 0.02mm to meet customer requirements.
