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
