Increasing wheel width improves productivity

     • Cycle time is shortened by consolidating two processes into one
     • This is made possible by adopting a wider grinding wheel

Automatic set-up change function
     • The Rich NC feature automates setup and changeover functions on 12 axes to speed setup time [Option]
     • Automatic wheel dressing after wheel change [Option]
     • An optional 3-axis NC loader supports various workpieces and allows long hours of unmanned operation [Option]

A diamond roll on the wheelhead shortens set up time
    • The wheel can be dressed during workpiece loading or unloading
    • Such simultaneous operations shorten part cycle time

CBN wheel with surface speed of 80 m/s [ Option ]
The GC50 CNC is a standard accessory with the Rich NC function
