I have done this with some knock-off Hiwin rails. Usually, the bearings are what goes out first instead of the rails (Unless the rails are not hardened). I know the rexroth are hardened rails, so you...

I have done this with some knock-off Hiwin rails. Usually, the bearings are what goes out first instead of the rails (Unless the rails are not hardened). I know the rexroth are hardened rails, so you...
Pretty much any rail 20mm or bigger has retaining clips in them, preventing the bearings from coming out when taken off the rail/temp block. When I have to take my bearings off for some reason, I...
I have. Got 2 1200mm 1605 ballscews as well as 6 1200mm 20mm linear rails for my diy router. They work really well. Had to pull the bearings out and clean them (which you should do with any rails...
I don't think I will ever have the balls to use a hand held circular say like that on metal, even with a metal cutting blade.
I am currently using a chop saw with a mist blaster system on the...
While the front bearings are most of the load that will be seen on the spindle, it's still worth the time and money to maintain the rear bearing as well. This is because it keeps the spindle steady...
Post this in the correct sub thread and you might get more replies. Posting in the eBay ads forum will not get you much in terms of help.
Both are great machines to learn on and upgrade later. It just depends on what type of machine you want. The C-Beam had a moving table, while the Sphinx has a moving gantry for Y. Before I had done...
If your looking at a learning machine, I would look into the OpenBuuld's C-Beam or Sphinx. They are much more forgiving, have a good drive system (leadscrews instead of small 5mm belts), and a lot of...
So what it's saying is you have 6 7/8" is usable travel in X and 18 7/8" in Y. In truth, it's probable 6.5" x 18.5" in travel with whatever you have on Z. The tabel size listed is just that, the...
Tell me about it. 2.2kw Spindle, 25mm Z-Axis plates, linear rails for both X and Z, Ball-screw, and the 35mm plates for the gantry itself. And that's just the gantry.
The table (base) currently as...
Not so helpful.
Anyone else have any input on this?
So, I have a used ES-MH234120 (12N.m torque, 1700 oz.in).
What I'm trying to figure out is would it be worth using it as a Spindle motor on a manual mill (Being converted to CNC) in place of the...
I know how you feel on weight. I'm redoing my whole X axis on my home made router. With everything that is going on it, it will almost weigh 50kg. Using 50mm x 150mm x 1m of 6061-T651 solid Aluminum...
If you can live for a week or 2 figuring out how you want the motors to mount on the ama30lv (if no conversion can be found), you can prototype some parts on the machine itself, then bolt the metal...
The 12pin is the connection for the encoder. I would look around for a cable if you can for the motor. As for input voltage, I would see about getting a transformer but also at the driver that is...
If it is the dovetail box, then I would say put linear rails on the Z-Axis. If the manual mill is big enough, you should be able to take the column off, secure it to the big manual mill and mill the...
True on all accounts. As long as the RPM isn't lower than 1000-1500 RPM, it will work well for what I need. Unless I completely re-design my whole machine, I don't think I will be maxing out the RPM...
So, I think I am going to change to the DYN2 drives with a 750 motor. Honestly don't know if I want to run the DYN4 servo's at 120v. Was going to use either a 1000w or 1500w toroidal 70v power supply...
I know if I never go above the rated amps (Which is 2.8A on the Dyna4 at 200v...Didn't look at the DYNA2 though.), you will never do more than at most 5A (Because the amps required is a somewhat...
I was wondering that as well. If it does, the CNC is on it's own 120v, 25A breaker. So if the amps are double, the breaker will handle and still have about 25% over-head room just in case.
Ok. So that's not bad at all. I had calculated the max speed (@3000rpm) to roughly 500ipm, and knew I would never be able to get that on my home machine.
I was not expecting to go over 1000rpm on...
Was looking into possibly getting the DYN4/400w 200v kit for my homemade CNC router and wanted to know a little more information on the voltage.
The drivers say they can handle 110-240VAC. If...
@Matth
If you ever decide to get rid of the 400w servos, hit me up or post them in the classified section. I had just started looking around for servos to upgrade my machine from steppers.
...
Your going to want to change the fitting on the radiator (if it came with them) to something like this. It has a output for a 1/4in Id hose, or in metric standards, 6.35mm.
...
The .005" you posted as stock left. Was that in the stock to leave section in the can profile? If it was not there but in the section up top for finishing passes, then you might have stock to leave...
The last statement is true, to an extent. If you are using Clearpath or Leadshine servos, they have a software setting for setting the steps. Clearpath's usually sit around 1200step/rev, but majorly...
I would look into getting something like the link below. You will need to find out what size you will need, then get one for each side of the moving axis. Roughly 60% of the length of the axis x 2 of...
Did you check the steps for the system? They might have to be adjusted. Using a calculator is a good starting point, but you have to take into account the design differences in your moving parts. For...
Was wondering if there was anyone in the Norfolk or Halton Roads area in Virginia that has a manual mill or similar that can surface 2 sides of a 2in x 6in x 40in piece of solid 6061-T6511. Don't...
Depending on what they are charging for the upgrade, it might be cheaper to get the materials yourself to upgrade to a linear rail/ball screw Z-Axis. I do not own a CNC Router Parts machine, but on...
