Features
- The two-axis CNC dresser can accurately dress steps, curves, arcs and other grinding wheel shapes, and at the same time, it can store multiple sets of dressing programmes to match different workpieces, making it easy to change types.
- The combination of servomotor and ball screw effectively ensures sensitive and precise feeding, which significantly reduces the dimensional dispersion of the ground workpiece.
- The guide wheel main drive with rolling bearings provides reliable rigidity during grinding by applying a preload during assembly.
Applications
- Compact and efficient centreless grinding machines for mass production of small and medium-sized precision parts.
