Well I got my mill today from QMT. They were very nice to deal with and very quick shipping. 1 day is un-heard of for a freight shipment like this.

All in all it is a very solid mill.

There was some confusion on another thread about the travel.

Mine as follows:
X: 19.125"
Y: 7.125"

It fit very nice in the back of my Durango


The provided stand


X travel


I had to disassemble into 3 pieces to move it my self




A little comparison of the X2 table.


More to come

How did you lift that beast into your truck?

[Starleper1]

With another person.

What is the actual X travel of the 25?

[gd.marsh]

Sorry,
I missed it when I scanned through your thread .. guess I ought to do more reading and less looking at pictures!

[Starleper1]

no worries I do the same.

One thing I do want to note is that the stand will need to be mounted to the floor. I would be very nervous making chips without it secured to the floor.

Yeah, it's way too tippy with machine feet in the provided points. What I did was to drill 1/2" holes in the front 'foot' of the stand to mount my hocky puck feet there. Works better but it still will wobble if you get aggressive with the handles. Once I know for sure where I want it to stay for good I'll get it mounted to the floor.

[Starleper1]

That would probably work a lot better if the hockey pucks were twice the size in diameter. Giving you more surface area on the floor. But it would like a little funny.

Well I had my first discrepancy. I started to disassemble the base and table, and when I took off the end plate on the left side, the inner thrust bearing was missing. Odd I thought, but i have seen this before believe it or not, where there will only be one thrust bearing and the screw rotates against the back side of the plate. Which is the total wrong way. So i took off the right side and sure enough there was one on the inside.

I'm not too worried about it because everything is going to get replaced anyway for CNC but just a heads up.

[photomankc]

Hopefully your motor controller lasts longer than mine. Appears this weekend is shot for me.

There is only one bearing used in all the bench top mills I have seen so far. My Weiss 30 had the same thing. One end floats and one has the thrust.

Embarrassingly Noob question for anyone with a pm25. Since this model does not come with useful instructions, I've been referencing Grizzly's from the G0704. When mounting an R8 arbor, it said to make sure to line up the slot of the arbor with the pin in the spindle. There is no pin in my spindle....but I do see the obvious slot in the arbor. Do these spindle pins (keys?) only appear in some models and not others? Can someone confirm that they also don't have a pin in their spindle on their pm25? I obviously never mounted an R8 before. Thanks for any help.

On my Weiss 30 the pin which is a set screw fell out before it got to me so it is not there right now. Lower the quill all the way and rotate the spindle by hand and look for the hole the set screw was in. It may be loose or gone. If you replace it you will need to make sure the new one fits the slot in the r-8 shank and some locktie is needed.

You can still mill fine without it but make sure you tighten the collets fully and don't use a fly cutter or face mill.

Found this in case it's useful to anyone later. It's the motor controller used in the PM-25.

Looks I'm not getting but a few millivolts at the A+ A- connections from the driver board. :/

I also have no pin in the spindle nor is there any visible hole in there where one should be.

[madbee]

Thanks for the pointer, but I looked and there is no location for any set screw or any hole of any type. I lowered the quill all the way and looked all the way around the spindle and quill. I also looked inside with a flashlight and there is no apparent hole were a set screw might come in. Intuitively, the slot on the arbor should have a mating key....when I did not see it, I looked at the Grizzly manual. Is my spindle missing something?

photomankc, thanks for confirming this. I thought I was going crazy after re-checking for the 100th time. I wonder if it's possible if they missed a step in this production batch. Anyone experienced with multiple machines care to tell us if this is something that should be necessary. Thanks for any help.

R8's do have pins to keep the collet from spinning while you tighten the drawbar
but it isn't necessary for holding the collet during use.
Power drawbars like pneumatics types allow you a free hand to hold the collet yourself.
I've only had problems on a kneemill trying to hold a sticky collet with one hand, the brake with another and tighten the drawbar with a third.

[madbee]

Thanks Hoss. btw, does your G0704 have a pin in the spindle?

[hoss2006]

Yeah it has one, it's farther up inside than most R8 spindles i've used, but it is there.
I noticed it in this video.
