feeds and speeds
Posted: Fri Aug 17, 2012 4:04 pm
Hello - I have just purchased a CNC Shark Pro Plus HD and teamed it with a Bosch 1617 router. I just purchased some bits, some 2 flute ballnose bits of different diameters, a few down cut spiral, and a 3/8" single flute compression bit. I am wondering if I could get some advice on speed settings for the router, speed for the cutting, in/min, and also depth per pass.
The guy at the bit place was saying that the rpms should be quite low and the feed rate be quite high. Like around 10k rpm and around 200 in/min for the larger diameter bits. He recommended 100 in/min for 1/8" bits and below. Also depth of pass should be maximum of diameter of bit.
I would like to hear from other people regarding these settings. I would hate to burn through or break these pricey bits. Thanks a lot in advance.
Cheers Peter.
