    CNMG toolholder styles

    So I was surprised. For several days after posting this I didn't see any reply's, so I figured thread was dead. One thing I will bring up. DCLNL is the best system I use, quicker indexes and less explaining for operators. One torx wrench. Instead of the 1/8" and 9/32" allen keys needed for a...

    CNMG toolholder styles

    Hello all, long time viewer, very infrequent poster. I'm posting a thread to ask for opinions on a common CNMG OD holder. I use left hand typically for heavy roughing anything on my CNC lathes. Right or left hand, the last letter would designate the hand of the holder. I've attached pics of...

    YG1 Spade drill insert question

    65 SFM seems slow to me, but that is D2. But I imagine it’s in the annealed condition. I run 5/8-3/4 deep drills in 4140 Prehardened at 150SFM but .004 per rev. The 4140 is around 28-30 HrC Sent from my iPhone using Tapatalk

    Lathe Live Tool Rebuild Grease Quantity

    Don’t know if this is of much help. I have several styles of driven holders. The Hardinge holders actually have grease zerks on them to grease the bearings, and what appears to be a low pressure seal at the opening of the spindle where the old grease pushes out. And a riveted tag on the holders...

    servo jitter

    At a previous shop location, I had a similar problem. It turned out one of the tap connections from a large pole mounted transformer had corroded on one phase. The connection must have been pretty bad for a while, and once the shop was pulling some amps a phase would go really low. It was worse...

    Bale Spike Hydraulics Problems.

    Same problem, but with a hydraulic tilt gooseneck trailer. It was the solenoid that powers the motor. Motor doesn’t spin in reverse, it’s simply powering a hydraulic pump. Reversing the direction of the cylinder happens from changing the flow through two solenoid valves, shown in your pic Sent...

    Hard Bar Ends in HR 1045 ???

    1045 has a higher carbon content then even 4140. Not by much. Nonetheless, 1045 doesn’t have all the other alloying elements that make 4140 a much better alloy steel. I grew up as a kid running CNC lathes, and I have personally ran hundreds of thousands of spindles for agricultural equipment...

    Worm Gear Programming

    In my Marvel saw, it has a developing worm. Certainly a multi start. Bronze lower gear was roasted by no attention, and no gear lube. Sent from my iPhone using Tapatalk

    Worm Gear Programming

    I had my head wrapped around the concept until that [emoji16]. So can a double enveloping worm be manufactured using a lathe without a C Axis? Technically? In my opinion yes, but not easily. Sent from my iPhone using Tapatalk

    Worm Gear Programming

    I noticed that in my second post. Most double-enveloping worms I’ve seen are also multi-lead. Is that generally correct? Sent from my iPhone using Tapatalk

    Worm Gear Programming

    After closer look at your picture, it looks like a single start worm gear shaft. Also, maybe not a globoid. Sent from my iPhone using Tapatalk

    Worm Gear Programming

    I’ll be honest, I’m going to follow this thread because this is something I’ve ran across and I am equally interested. For the OP, here is what I know. That appears to be a globoid worm shaft. There is a radius that “wraps” around the female part of the worm gear. The area where the “threads”...

    Mori- Seiki SL-2B Z-axis limit switch -- where is it?

    I have a SL35 and a SL45. Newer machines, but as far as I know the Z limit switch is on the back part of the casting of the cross slide. I have to remove a sheet metal guard, and the switch is pretty much in plain sight on mine. I’ve had a limit switch from a Kitamura VMC that also stuck the...

    pipe taper tap thread depth?

    That is similar to what my Solidworks spits out on a drawing. Basically Solidworks says NPT has to be that depth. I use that z value when threadmilling NPT. Sent from my iPhone using Tapatalk
