SUMMARY

The discussion focuses on resolving chip formation issues when milling BK7 glass using an Ichikawa Milling machine. The user reported producing chips on the edges after performing a 'ralf cutting' operation at a speed setting of 60. A suggestion was made to adjust the cutting parameters by taking a lighter cut at a higher speed while reducing the feed rate to improve the milling outcome.

PREREQUISITES
  • Understanding of milling machine operations, specifically Ichikawa Milling machines.
  • Knowledge of material properties, particularly BK7 glass.
  • Familiarity with cutting parameters such as speed, feed rate, and depth of cut.
  • Experience with chip formation and its impact on machining quality.
NEXT STEPS
  • Research optimal cutting speeds for BK7 glass milling.
  • Learn about adjusting feed rates and their effects on chip formation.
  • Explore advanced milling techniques for glass materials.
  • Investigate the implications of different cutting depths on machining performance.
USEFUL FOR

This discussion is beneficial for machinists, manufacturing engineers, and anyone involved in precision milling of glass materials, particularly those working with Ichikawa Milling machines.

1)Anyone can figure out the chips problem due to milling a glass material BK7.?
2) I am using Ichikawa Milling machine where the table rotate and the spindle rotate to mill the material. After do ralf cutting which I set the speed to 60. It produces chips on the edges of the piece.

Welcome to PF, Wise. You might need to clarify your question. I've had limited experience with machine tools, and your terminology is meaningless to me.
I've never heard of 'ralf-cutting', and your number '60' could mean anything from rpm's to depth of cut in thousandths. Please be more specific.

edit: As to the '60', I know that you said that the speed was set to '60', but that could still indicate a progressive depth vs. time as opposed to just rpm's.
 
First thing I would try is to take a lighter cut at a higher speed with a slower feed rate.
