Hi guys. This is a little video using a D=35mm 3 flute insert cutter and the PM940 CNC mill.
The inserts used are the APKT1604- MA3
This is a ground carbide insert for soft metals.
Generally I don't use the 35mm cutter much as the smaller ones work better for ruffing most the time and the larger face mills are better for facing.
For this job however it's is just right.
For this cut I needed to remove .250" from the stock and I wanted to see how the 940 would do with the stock motor and gearbox.
With the VFD at 95Hz I will have about 2,800 RPM and with the larger 35mm cutter the surface finish was really good. I could have gone much faster but I didn't want to junk anything right now, I need the mill to cut parts.
I know the camera focus is all over the place, I forgot to lock it.
I will do more on the insert cutter in the future.
Thanks
Dave
