Is it possible to reduce the spindle rotation speed on a CNC router below it’s normal speed range?
I’m going to be using a CNC Router to flycut some MDF and I want to create a slightly rough surface. One machine I am considering buying has a spindle rotation speed range of 6,000 to 24,000 RPM. Does anyone know if it is somehow possible to set the machine to cut at a slower rate?
Do-n-it-4U. Re your answer. If I use a dimmer control, will it reduce the router travel speed as well? As I see it, for me to create a rough surface I either have to increase the travel engraving speed or reduce the spindle speed rate. Obvioulsy being able to do both would be ideal. However, if by slowing down the spindle rotation rate by using the dimmer, you also slow down the travel speed then I would imagine it would pretty much cancel the overall benefit.
I would talk to the manufacturers technical personnel and ask them. Using home remedies on professional equipment that will void the warranty is not how I would go.

Yes, get a dimmer switch and wire it in line on extension cord and you can control the speed by the amount of electricity you provide. Just like a light that is on a dimmer, the light is not special it just isn’t given all the juice. Oh, I should mention ensure you get a box for the switch. Easy stuff, and a cheap fix for your problem. Also this will not damage your router. good luck
