I've got to replace the main spindle belt on an old T42 built in '96.

The manual doesn't show a procedure for changing out the main spindle belt which is contained between mounting plates for the...

Beware that acetal creeps. An aggressive press fit will relax over the years, but it probably won't get totally loose. I've had some success with the kind of fit you're going for with light...

Not sure if you've fixed this yet.

I just had a similar problem with a chucker lathe. We opened up two air guns on the same line and saw the inlet pressure to the machine drop rather more rapidly...

I'm considering a used Gildemeister lathe to replace a Daewoo MSA 200 PUMA which has been serving me quite well. I've got a job which requires a larger spindle pass than my Daewoo. I don't...

I agree with Al. Buying a machine without being able to inspect it under power is a risky venture.

Can you disconnect the bar feeder and check the machine out otherwise? If they can tell you which...

Wipers seem to be in good shape. No tears or lifted areas.

Anybody?

I took a look at my lathe (Puma 200) and saw that the upper Z axis rail seems to be getting less oil than other rails. The upper rail typically has a light film evenly spread on all of the sides, but...

We're having problems with our bar loading macro not recognizing when the loader wants to load a new bar. The first bar loads fine, but the lathe is not seeing the new bar signal between parts on...

Most filtration does little to remove dissolved mineral content. You could get a water distillation doodad though:

Is the right angle tang broken off yet? Helicoils have a bent bit which is used to drive them. Usually this bit is broken off so a screw can pass all the way through, but if it's still there, you...

Pressure stacks up pretty fast. For your 55ga lid I'll guess a dia of 24". This give a rough area of 450in^2. If the barrel is 4' tall, you'll need roughly 1.7psi to push it up past the gravity...

What is the experience base in your company? If you've got some experienced machinists who are a bit savvy with equipment troubleshooting, you can get excellent value in the used machine market. A...

Sorry, I mistated. I meant to say that the previous owner of MY machine may have swapped my quad with an "O" ring. My bad. I.e. I should not get too hung up on your machine having a quad ring because...

I think I shouldn't dwell on the oring issue. I got my machine used. It's possible that the previous owner put in an oring instead of a quad ring and I just went along and replaced it with the same...

Sorry, I forgot to look at my disassembly drawings today. If my fuzzy memory recalls, there is a check valve in the face of the big flange in the piston. Perhaps Nawrocki is referring to that valve....

Polypropylene may be a pain to machine. I find you need nice sharp cutters with rounded corners. Ball end is a usual choice. Flat end mills often leave hairy bits which are difficult to cut off...

You'd do a lot better with a used JET or other manual mill in the 2000lb range. Keep an eye on Kijiji and Craigslist. They come up from time to time between $1500 and $2500. Sometimes they even come...

I've got a T42 purchased with over 50,000hrs on the cabinet counter. Spindle bearings still seem fine. It looks like the machine was running a live tool intensive job judging from the number of live...

I can't say much about the business practices of machinery sellers in China (never having bought their machinery), but I did visit a shop in Ningbo China which was running a lot of economical CNC...

I think the inert gas setup might be the fastest turnaround. What kind of tolerances are you looking for?

Casting may be impractical as Calcium has a fairly high melting point at around ~800C....

Nawrocki4Life: It's too bad I didn't try a post here first. I did try every one of those fixes except for the special power up. We did eat up an hour of technical support from Hardinge, but they...

After being disappointed with a Syil C6 I have moved onto used industrial CNC heavy machinery. Certainly not a reasonable decision for a desktop purchase (unless your desktop can support a ton or...

I did try that first. What happened was that the machine would count distance and hit a soft limit long before getting close to the hard limit switch. Very frustrating. I think what had happened was...

I had a similar issue with not being able to move Z axis to home. I kept hitting a soft overtravel limit before I could get the machine to find the home point. My machine is a different build though:...

I'm considering a used Hennig conveyor which was intended for a Fadal 6535. I'm putting it in my Matsuura machine which uses a shorter conveyor, but I think I can do a chop job on it to shorten the...

Thanks for your replies guys. It's very helpful getting a little perspective on this issue.

I've been looking at some of the installation guidelines in my lathe manuals and have seen some pretty significant discrepancies between machine makers. Some of it makes sense. Not all machines have...

Thanks Stealth.

I used to believe the "tooth multiples" rule until I got lazy and munged knurls into any given diameter I felt like on my manual lathe. There doesn't seem to be a need to knurl on any particular...
