First, disc parts common processing problems:
1. Clamping easy deformation, flatness, parallelism is difficult to guarantee
Thin discs, large-diameter discs with poor rigidity, stress deformation after chuck clamping
Loosening after processing, the size of the rebound, flatness, end runout super poor
2. High perpendicularity between end face and outer circle, difficult to stabilise.
The end face, stop, step and outer circle need to be formed at one time.
Ordinary machine tools for multiple clamping, perpendicularity, coaxiality is easy to exceed the error.
3. Difficult chip removal for end face groove, ring groove and deep groove processing
Narrow groove, large depth, poor chip removal → Scraping wall, pulling tool, poor surface
Tool easy to wear, unstable size
4. High positional requirements for centre holes, positioning holes and multiple holes
Distribution of multiple holes, angular holes, eccentric holes
Position, concentricity is difficult to ensure that the rework rate is high.
5. Large diameter disc cutting easy to vibrate, vibration pattern
Large overhang, high cutting force
Poor surface finish, end face ripples
6. Work process is scattered, low efficiency and high cost.
Turning → drilling → milling → tapping multiple machine flow
Clamping more, long cycle, poor consistency
Second, turning and milling composite machine tool solutions:
Complete turning, milling, drilling, tapping, slotting and boring in one clamping.
Eliminate multiple clamping errors, coaxiality, perpendicularity, positional degree of a standard.
High rigidity bed + high power spindle
Suppresses vibration of large-diameter discs, with smooth and vibration-free end surfaces.
