Gregg, I am using a common treadmill controller called an MC-60. I chose it after months of research and deliberation --NOT. Actually it and the motor were in the treadmill that I was given to get it out of a friends house. It is not four quadrant, just a simple scr drive, but it works just fine for my application. I do threading on this machine but not rigid tapping.
If you haven't installed the motor yet you will find that the treadmill motor's rated speed for the rated hp is probably around 6000 rpm so you will either need to provide an additional stage of belt reduction to get you down to threading speed with enough torque to do the job. Cecil >What controller are you using? I need one able to handle a 110 volt DC, 1.5HP treadmill motor. My 9x20 CNC conversion is on hold due to a lack of motor controller. >>I am running a cnc'd jet 9x20 lathe with a treadmill motor and dc motor controller with a 5k pot for speed control in manual. >>Thanks, >>Cecil ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, SlashDot.org! http://sdm.link/slashdot _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
