I agree with the drill press and lathe ideas. I'm no master machinist, but both methods have allowed me to have good success threaded some picky holes. Before I knew these tricks... look out :(
I would like to add that you can get special tap handles and die holders which make using a drill...
I've talked to several people about replacement parts for similar clutches and brakes. They all seem to accept that there is no friction material on any of these disks. Apparently it is not an uncommon approach. It's not even really that the disks appear to be worn, but rather than they lose...
Hello. We've been trying to find a source for clutch and brake disks for a metal lathe which is no longer supported. We finally took it apart and measured the disks. We are thinking about just having new disks cut on a waterjet machine, as there really doesn't appear to be any rocket science to...
I did not say I used a string-pot sensor. The Elap sensor I use resolves 0.002" (0.5mm) over 14 inches. That's 7000 counts. It's in a neat package which easily two-point mounts, too. It has a simple quadrature encoder interface. I asked if anyone could suggest something similar. Thank you.
I fooled around with the Teco SG2 software downloaded from factorymation.com and have to say I was very disappointed in its limited abilities. If all you want to do is some very basic logic or interface to i/o points, it might work ok, but it seemed pretty difficult to use for any significant...
Yes, the MTS parts look familiar. I believe I looked at them or something similar. As I said, their output signal choices seem odd to me; I guess they are geared towards OEM use with machine networks. Quadrature encoder (which is supported by virtually every PLC on earth) is apparently not...
I was recently looking for a cost effective linear quadrature encoder for measuring position of a press with a PLC. Basically I wanted something resembling a pneumatic cylinder, relatively rugged, with a straightforward quadrature interface. Absolute encoding would be a plus... Stroke needed is...
I agree with the comments on the Koyo DL05 and 06. They are nice units and the support software is pretty good. Unfortunately you have to buy the full software, which will exceed the hardware cost for your one-off project. AutomationDirect has recently added a "Click" lower cost PLC with...
We have a Bullard 56" Dyn-Au-Tape vertical turret lathe (VTL). The automation (lol) was removed long ago and we just use it manually. We are considering replacement of the two drum controllers (drum sequencers) which apparently control acceleration of feed and traverse. I think they were made by...
Hello. We have a WMW Niles lathe, 32 x 120, which needs brake band and disk parts for the spindle brake. I am pursuing the parts with Simmons/Niles, but was wondering if anyone knows of an aftermarket source who makes these parts, or possibly can reline our parts (less desirable, since machine...
Hello.
My employer has a large "Sellers" brand planer/miller, what some might call an "openside" planer. It has a 48 inch by 20 foot table, with 40 feet of table travel. It's an old machine, but it's in pretty good shape.
We have no documentation on this machine and would like to talk to...
Nice! This isn't a super high value project (being in-house on an infrequently-used machine), so the simpler the solution, the better.
Anybody needs keyways cut in 30 foot long shafts, give us a yell ;)
Thanks!
Thank you for the tip! I will download the ABB manual.
What I envision is a _programmable_ reverse/stop point. The operator could put the machine in lowest speed, manually control it to the desired point, press a button to set the reverse/stop point, then switch to a higher speed range to work...
Hmmm, the more I think about this, the less likely it seems that it could work. I would think you wouldn't get nearly enough feedback about the motor dynamics. In our case the load is going to be pretty constant and we aren't that interested in that feature, more so in the position feedback, but...
