Cylindrical Grinding Machine

Cylindrical grinding process for the end-mill & tap.
→Infeeding & Traverse : narrow width wheel type / Straight & taper grinding possible.
Centerless grinding can manufacture the hollow shaft material even if it is difficult to supported by chuck & center.
Increasing the productivity by shortening process time.
Wheel dressing equipment saves the process cycle time, lengthens wheel's life, lowers defect rate and raises the productivity.
Linear scale(Heidenhain) increase the precision
The grinding margin is minimized because workpiece is not supported by center.
Auto-loading & unloading system increase the productivity considerably. (Option)
Auto wheel balancing function prevents the chattering of tool and keep saurface high quality level.
Built-in cone dressing unit for rubber roller.
→Reduce the process cycle time more than 50%
→Secure the regular grinding quality of tool.
→Save the time for remove and assemble the rubber roller.

Automatic compensation increase the convinience and reduces defect rates.
Possible stepped outer diameter grinding work.
Hydrostatic system of each feed axis gives superior surface quality and increase the roller screw's life.
Wheel dressing equipment saves the process cycle time, lengthens wheel's life, lowers defect rate and raises the productivity.
Auto-loading & unloading system increase the productivity considerably. [Opt.]
Swing and tilting function of wheel minimize the friction area offers high grinding quality.
Auto wheel balancing function prevents the chattering of tool and keep saurface high quality level.
With Automatic Tailstock, stable workpiece support
