What are the available VFD speeds for the SWIFT CNC? I plan to drill ~100 holes through 3/4 & 1” Baltic Birch ply. Looking to use an Amana brad point boring bit. After reading through previous posts on preventing fire and peck and drill vs. undersized mill / pocket techniques, I believe this boring bit should work optimally with peck and drill at the lowest spindle speed @ high plunge rate for my application.
I don’t recall the available speeds on the VFD controller.
The spindle will go from 0 rpm to 24k rom. You’ll need to adjust it on the digital readout on the control cabinet. Remember the readout displays hertz.
Great!! For some reason, I thought someone stated here that there were only 8 speeds available. Nice to have full control of rpm. This particular bit says that it is commonly used at 5k rpm in CNC manufacturing without burning the wood.
2 follow up questions:
Just for confirmation, the only way to change spindle speed is by manually adjusting the frequency controller on the console, regardless of what is in VCarve / gCode, correct?
To convert to Hz, would I just simply ratio the rpm to the range of the spindle HZ?
Hztarget = RPMtarget(Hzmax / RPMmax) Is SWIFT 400 Hz at 24,000 rpm?
