Coolant or not? - Practical Machinist

Thermal cracking of carbide is much more of a problem when milling than turning. Interrupted cut turning is more like milling where the tool is very rapidly cycled in and out of the coolant and will often benefit from shutting off the coolant. Coolant helps to stabilize temp variations in the part and the machine.

Milling Feed. The feed (milling machine feed) can be defined as the distance in inches per minute that the work moves into the cutter. On the milling machines we have here at LBCC, the feed is independent of the spindle speed. This is a good arrangement and it permits faster feeds for larger, slowly rotating cutters.
