I'm not sure this is the right forum for this but it is electrical so...
I recently acquired a heavy duty drill press with a R8 spindle. I have gotten spoiled with the pneumatic draw bar on my CNC mill and the TTS tooling system.
I would rather not do any type of pneumatic system on this machine so I was thinking about an electric system. I see Griz has one for BP type machines but at $1100 that's out of the question. If I can't diy it for 1/3 that then I'll look at pneumatic.
The Griz unit looks like it uses a 22ov gear motor but give no specifications other than 2100 rpm, 7.5A and 240 ft/lbs of torque. How would one go about finding a similar gear motor? I poked around a bit but most I found listed torque in in/lbs and no where near what Griz is claiming.
The other question is how much torque do you really need?
