Possibly a Dumb post /Question? but i recently bought a CNC Taig Mill. Well it has mach 2 and I had a lot of trouble getting it going. Now i had the old laptop looked at in a shop . There was a problem Battery they said? Now i got it going am slowly learning. MDI working and Im boning up on circular interpolation and stuff. The question is ??It sure doesnt have much jam so to speak when its moving ?? you can stick a finger in the cross handle (Dont ask why i stuck my Finger in there i just did Im like that Yes I stiill have all my fingers and im 52 years Old LOL) and it stops? Is this normal? I thought it should have more torue than this? Im wondering how its going to cut material ? thanx Mike

not sure what you're asking, is that amount of torque normal for the taig, or is that the normal way to measure torque :D:D:D
Mike, too funny. I know you've run big cnc's, tell me sticking a finger in isn't the usual way you measure torque? when i get you up here to show me how to use my bridgeport i know theres two things i'll need, lots of beer and finger splints.
PS, just picked up a nice little Taig lathe, maybe for tradesees - that mill need a mate? compared to my uninimat, its quite a solide little machine. Haven't tried sticking my fingure it in yet, but seems to run well :D

Try stopping the table while it is moving. Bet you wont be able to!
Mach on a laptop is generally a bad idea. All sorts of timing issues. Find a cheap desktop.

Doesn't seem like very much, but that's not exactly designed to be a hogging machine. I once wrapped my shop apron up in a manual mills handle while running the table over to the workpiece in several directions at once. :eek: :o Hell of a bind, I was on the other side from the power feed. I couldn't reach the power feed to shut it off so I had to hold it back while unwrapping myself. It really was surprising how little torque there was but it's more than enough. When you think about it, it doesn't or shouldn't take much force to crank the handles manually.

I have two data points for my RF-45 CNC mill's torque under power:
1. It has snapped 3 or 4 1/2" endmills now. Not in a while, fortunately! Lost 2 due to rapids without thinking while getting used to MDI--DOH! Lost 1 or 2 due to inattention, followed by chip welding which made it unusually dull requiring more force, LOL. Easy to go do other things when the CNC is working.
2. Hauled A** with a 3" facemill to see what the max feed it would take was. At 60 IPM it stalled spindle and locked up the table. Chipped an insert, but that was all. Very exciting! Fortunately, this is a servo mill, so once things stop moving, it faults and everything stops.
Would not want a finger anywhere close to being in the way of any part of that mill that wants to move forward. I pop the E-stop any time I've got to reach under the spindle to make an adjustment.
