Thread: The New Machine
Hmm, that's nice but could be a problem long term as you wont notice if the thread or something starts seizing up. The impact driver will probably just keep going and potentially cause excessive wear / break something? Just a thought..
How long until automatic tool changing then?
i don't see it as going to be a problem as the drawbar is the soft expendable part. As the tapers and threads are hardened steel.
There are quite a few impact gun drawbar designs kicking around, and I've never seen anybody mention having any major problems with them.
Biggest issue with using an impact gun, is getting a consistent torque.
Also, don't rely on the threads in the taper shanks being hard enough not to be damaged by a soft drawbar. I bet if you tried filing them, they'll file down without that much effort.
Late into this post but converted 4 of these machines now based on the Warco WM16.
1605 ballscrews all round, 3.1Nm motors all round, direct drive on X and Y 2:1 belt reduction on Z
42 volts power supply and 542 drivers. If I had to do any more I'd increase the voltage to 70v and use the 80v 7 amp drivers de-rated to suit the motors.John S -
Im very interested in this machines capability.
I currently run a CNC converted Sherline Mill and im now realising i need something bigger and better.
Keep us interested in this project please
on my machine i used a G540 with 3 x 380oz and 1 x 940oz motors from kelinginc.
