Caution Cut-Off

1.Be sure to perform wet processing. Apply enough coolant to the cutting edge.
2.Keep a constant rate during processing so that optimal product life will be achieved.
3.Cut off as close to the chuck as possible.

4.Lower the feed rate to 1/2 to 1/3 at the near center to prevent impact caused by cutting.
