spindles

[NormanAlbert]

Hi one and all: Finally broke down and got DC spindles to replace the Bosh Colt routers I've been using. The smaller cnc now has a 1.5 KW air cooled spindle with an ER13 collet. It weighs 10 pounds so added a spring counter weight to almost negate that weight. My bigger machine now has a 1.5 KW spindle with a ER16 collet capacity. That weight is 15 pounds so it also has a spring counter balance setup. Both are 220 volts to the Variable Frequency Drives single phase and gives the spindles 3 phase. I have not hooked them up to Mach 3 for auto on and off. They do have soft start and off. The best thing is how quiet they are, how powerful they are, the cutters can take a bigger bit and faster feed without loading the spindle down. And yes, the cutting action is nosier. Norm

Why would the cutting action be noisier Norm? Less other noise to hide it?

More aggressive cutting makes more noise.

Hi Guys: Yeh: The spindles are so relatively quiet and I can run at a greater rpm and feed speed the cutter noise isn't masked by anything. Norm
