Thermal cracks? did you know already?
26.03.2009
 |
Small cracks perpendicular to the cutting edge cause chipping on workpiece and poor surface finish. |
| |
|
Cause |
|
Surface speed too high, feed per tooth too low, excessive temperature variations, or
varying of coolant supply, interrupted cuts. |
| |
| Solution |
|
Reduce surface speed, increase feed per tooth, flood with coolant continuously or shut
off coolant, select stronger edge condition, reduce entering angle. |
