Monarch 10EE Electrical Problem
Does the RPM go truly to 4000 or is it in a runaway condition due to having no field at all? On my 1967 machine, I sometimes get the runaway condition if I start the machine with the speed setting above about 2500 RPM. On the other hand, if I start the machine below, say, 2000 RPM, then I can...- rklopp

A simple question....I hope
Find someone junking an old Deckel FPxNC control. They rely on 240-380 3-phase transformers in the US. User "rimcanyon" here on PM might have something.- rklopp

D4 Programming Question
I can think of one way, but it's dumb and inefficient because it always runs the second pass but only cuts metal when necessary. Assign one parameter for each of the 8 locations. The parameter is either the full depth or, say, 0.001 depth of the second bore.- rklopp

Manual Lathe Recommendations
With that budget, you could buy Procyon's Weiler and be spoiled for life. Lower on the totem pole, Sharp, Kent, Acra Turn, and Acer all seem to be in the same ballpark, if not the same manufacturer. Gr!22ly's South Bend line seems to be of the same ilk, and they publish prices. The high school...- rklopp

OT: Best steel toe shoes for everyday
I've discovered and like slip-on Blundstone boots. They're Tasmanian. They're good for my garage shop because they're quick to put on and off to keep chips out of the house. -
WTB 48 DP 14.5° PA #3 involute cutter
Anybody have a good, sharp, 14-1/2° pressure angle 48 DP #3 involute cutter to sell? I bought a China one from Victor Machinery Exchange and it was complete garbage. The profile was way too fat and there was 0.01 runout, at least, on a 1.75" cutter so only a couple teeth did all the work. I also...- rklopp

FP4NC with NC-T400
I’ve rented a drop deck trailer from 5th Ave Rental in Redwood City a couple times. Don’t know if it would carry 3 tons. I’m glad you’re not using your old trailer.- rklopp

Been away for about three years, cheap FANUC O-M/C simulation?
Are you planning to use finger-CAM? If not, nearly every CAM program nowadays lets you play tool paths on a PC and can be trusted to output non-crashing g-code if you use a reliable post. If the CAM path looks good on the PC, it's likely OK on the Fanuc. Do an air cut if you want, do the first... -
15K Spindle Warmup Dilemma
Barring a crash or contamination, spindle life is based on the number of revolutions, which controls the number of fatigue cycles on the bearing races. If you lower the RPM, you have to lower the feed rate to keep the same chip thickness, so parts take longer to cut, but still require the same... -
Remove Large gear from shaft - damaged key
Oof! Brute force seems to be the way to go, given the level of damage. You'll need a big press. I doubt heat would help much since the key interference is going to be massive, and you can't expand the gear to expand enough to undo it. If the gear was driven by a single pinion, there's a chance... -
Deckel fp3 nc
V means verschmutzig, i.e., your Z scale is dirty (or worse). Here's a link with info on how to clean the scales: https://www.practicalmachinist.com/forum/threads/repairing-heindenhain-vrz-753b-ls803-scales.284063/#post-2280294 There are other links you can search.- rklopp

Verniers for sale
Weird, isn't it. I'd say "Hand me the vernier calipers," but "Hand me the micrometer caliper." (Well, no, "Hand me the mikes.") :willy_nilly:- rklopp

15-5 part sanity check
I bet the OD is changing as you cut the ID, so the ID is whatever it is when you cut it. I doubt it moves much after you stop cutting the ID unless temperatures are way out of hand (apparently they are not) and chucking forces are not ridiculous (apparently they are not). -
15-5 part sanity check
Come to think of it, if you are machining in the solutionized and quenched condition, you may have a residual stress issue. Shrinkage would occur if the ID was in hoop compression and the OD in hoop tension after you turn the OD but before you turn the ID. Think of the ID "propping" the OD... -
