Nothing special. For the ballscrews I use a general purpose automotive grease and for the spindle bearings, I use a "high performance" automotive grease. No issues or complaints, but I can't say...
New ballscrews arrived!!! I have to say, the difference between this set of screws and the first one I got is like carbon black and the surface of the sun. Ok that might be a bit of an...
FYI, it is a PM-25, there is no PM-20.
I finished putting the way covers together and I am hopeful. They stay together well look to fit pretty well too. A few of the sheets aren't completely straight, so the spacing between each...
Thank you for the compliment!
I currently do not have my machine set up for rigid tapping. At some point, I may add an encoder to the spindle to make that work, but I have read that the servo...
When I did it, I just cut the threads off and used a set screw. I never had any problems.
Why do you think the cover isn't a good long term solution? Does it do anything but deflect the chips that make their way up there?
I made some progress on the way covers over the weekend. I had a little bit of trouble getting the sheet metal to cut right on the machine, but a little bit of tweaking and a few failed parts got...
I suppose shortening them up later is always an option. If they end up feeling too long or like they are taking up too much space (Though they are door handles, I don't imagine it making much of a...
So the boss says "I have a job I think you can handle."
Got the machining for the handles finished. I am not sure if I will keep them this long, but this is the general idea. The end parts...
Thank you :) My parts get hit with a chamfer mill any time it can reach. The operation usually takes less than a minute and saves me lots of time later.
I got the enclosure all bondoed up and primed. I had the darndest time getting my little HVLP touch up gun to spray the primer well, so I ordered a full size HVLP gun which made short work of ...
Getting close to the end with the new enclosure. I have finished up most of the weld work, got the front opening all framed up, got new sliding rails for the doors, resized the doors from the old...
I was using 400 oz in steppers on X and Y, and a 1200 on the Z (though that was way overkill for the Z).
I have 750mm on X, 350mm on Y, and 600mm on Z. Z can be a bit longer with no problem.
I have been working on the enclosure for a couple of weeks now. It uses steel square tube as a stand and sheet metal for the body. This is only my second excursion into welding and the first time I...
I little bit more information might help give you some better answers.
1. When you say you get the spindle to turn on but the RPM does not match, are you able to control the speed through Mach 3...
On the X2 that I had, the leadscrews were not accurate at all. Compared to an inexpensive DRO, the dials didn't even seem close. Even cheap $40 rolled ballscrews were miles ahead of the leadscrews...
You can do 2005, no harm there.
From all the spec sheets I have seen, the 1605 will have a dynamic load rating around 600 kgf. With a 75lb head (standard weight was around 55 lbs, then air...
On my PM-25 (very similar in size), I used 750mm 1605 double nut on X, 350mm 1605 double nut on Y, and 600mm 1605 single nut on Z.
It won't fit. You would need to go with a new head entirely. Also note that the 90mm is the outside of the body, the flange is 126mm. I would consider selling the X2 and buying a slightly larger...
You are probably pushing that cutter a little bit hard. 5x diameter cutting edge is a little bit high, so you will need to back off of it a little bit. You might want to step up the diameter to a...
That sure looks like a PM25 to me!
To me, it seems like something is off if you need 1200 oz in motors on the X and Y and are only getting 100 IPM (2500mm as you noted). On my PM25, I have double...
Stuart, you would be right. That was taken while I was making sure everything fit and moved correctly. A cover is planned, but hasn't been made yet. Most of the tool holders were pretty new at the...
I have a few 4" vises on my PM25. The two on the left were $80 ebay vises and are pretty good. The machining in a few places is a bit rough, but I use them almost exclusively with soft jaws and...
CPM-SDSK-2321S-RLN on the X and Y, CPM-SDSK-3421P-RLN on the Z.
It has been a while since I have posted anything here.
Two big changes to the machine are the Clearpath servo motors on each axis and the automatic tool changer.
The servos give me about 400...
I am using LinuxCNC with a parallel port break out board. It works well for the time being (and for the last 2 years), but I may need something better to support the rest of the things I have added....
They are plenty strong. I think people have a tendency to shoot for stronger stuff to compensate for poor adjustment or poor quality on other areas. It helps add a little reliability though in some...
I just mounted CPM-SDSK-2321S-RLS steppers on my PM25 on the X and Y. Powering them with a 48V power supply, it is managing just under 400 IPM before it starts to give me warnings. Both are direct...
