grinding threads feed rates. Get The Feed Rate Right When Thread Milling | Modern. For a 4.8-mm thread mill used to create an M6 x 1 thread, the feed rate at the edge of the tool is 238 mm/min. Conversely, the feed rate at the center of that tool is only 47 mm/min. Moving the tool too slowly leads to extended machining time (five times longer ...

What is Feed Rate in Machining? Its Unit, Value, Effects ...

Feed rate in straight turning—0.01 – 0.1mm/rev for finishing cut; 0.05 – 0.5mm/rev for rough cut. Feed rate in thread turning—Equals to the pitch or lead (for multi-start threads) of thread (usually 0.5 or 1.0mm/rev). Feed rate in drilling—Must be very low otherwise tool may break due to chip clogging. Typical value is 0.01 – 0.05mm/rev.
