Shop is 240 volt 3 phase. I have two edm machines using separate 3 phase multitap autotransformers to get from 240v up to 380v. Transformer says 12kva, machines say 10kva. Just added a third edm machine with the same multitap autotransformer setup. Getting the 380v out is no issue. The...

I have a 36 inch blanchard grinder running on 240 3 phase. Our shops incoming 3 phase has 2 legs of 110v and 1 wild leg that is around 255v. Volts are ref to ground. Phase to phase between any two shows 236-238. This machine was set up in an industrial plant running on either 440 or 480...

Saw there were several views but no comments on where to look. I had time this afternoon to really check the machine over. Went through every fuse, checked all the wire terminal screws, cycled all the breakers. Still had issue. Decided to pull and reseat all the individual pc boards. That's...

I have 2 working 290p machines and picked up a spare machine for cheap to salvage parts off of eventually but it was said to be operational before the batteries went down and it lost the software. This machine is a 1999 and mine are 2002 but mostly the same, console 2 control, only visible...

Got it removed, Major help from Hardinge, credit to them. Ok, when turning it left handed all I was doing was spinning it and moving the piston maybe. The hydraulic cylinder has a tiny key in its interior that was sheared off preventing the end I was turning from unscrewing the other end from...

Lost the spindle belts on my Hardinge serial DSMA-5c-326. My manual shows instructions to remove the standar closer and the varigrip but not this one. I took out the draw tube and the closer unscrewed left handed about 3/8 inch and now just spins but it doesn't pull off the spindle end. Dont...

I am looking at an Eaton screw compressor and would like to hear from anyone who has one or works where one is in use. I need about a 10 hp to take the place of my two piston type compressors. What kind of quality, service, reliability have you experienced with Eaton.

I have a couple of the ahc and a couple of the dsma hydraulic automatics. The main reason I can see for these to be priced low is the electrical issues. As long as an ahc is running its a sweethart. Very close accuracy and dependable repeatability. When one goes down though you better have...

machtool, Point well taken, it is pretty hard on the eyes without paragraph breaks. Not to mention trying to translate Kentucky hillbilly english into down under english!

This may help folks trying to dnc to a Fanuc. I ran into a job that needed a 500k program to machine a surface and my Fanuc OM only had 128k of ram. I use either an old copy of procomm or a newer version of hyperterminal for transfering smaller programs that will fit into the memory but I had...

We had this problem with oil grooves during the mid 80's at a company I worked for. We made a lot(100's) of bronze bushings from .75 id to 4.5 id up to 8.0 long all of which needed spiral, figure 8, or double 8 grooves. I looked into used factory built grooving machines, all of which were...
