Samchully 10” chuck in my Hyundai SKT28LM is having an issue with runout. However, it isn’t consistent. I’m running soft jaws and the runout is changing +/-.005 depending on how the chuck is oriented It had runout when I first got it. I removed it, cleaned it and reinstalled it. It still...

Working on a part that starts 1" round 303 Stainless. I need to put flats on either side and then counterbores as shown. I'm running a HAAS VF2 with SRT210 4th axis. I also have 5C indexer. My VF3 with the good 4th axis is tied up with another job. I'm not sure I trust the SRT210 to...

I just had this machined offered to me. Not sure what tooling comes with it. Looks like the power supply has been updated. Anybody have any experience with one? is it worth hauling it home?

I got some tool holders for my Hyundai SKT28 running VDI40. I seem to be having an alignment issue with a plain bore tool holder (the plain metal one, not the black oxide finish) that mounts radially on the turret to hold drills and boring bars. Unfortunately I am unable to post a video. Running...

Just picked up a No18 Blanchard. Loaded it up and drug it home. She needs a bit of cleaning, but it looks like it’s in good shape so far

I’m looking for internal plug thread gages and external ring gages for AWJ tapered pipe thread and NWJ. So far I’ve found limited information on these, making it difficult for me to even attempt to make my own gages.

Working with my Hyundai Kia SKT28LM with FANUC 0i control. In MDI mode I am able to command M83 to automatically position the main turret in alignment with the tail stock, engage the shot pin and release the clamps. After attempting to adjust communication parameters, I now get error “3002” ...

The Hyundai Kia SKT28LM lathe I picked up came with a 10” Samchully chuck. I noticed a bit of runout in the chuck and figured it was just in need of a good cleaning. I was getting about .005” of runout on the parts. Often times it’s not an issue, but when it is, it’s a real problem. I put a...

Having a bit of trouble getting through some 304 stainless. I'm using a HSS #54 (.055") drill going 1/2" deep. Currently running 4500rpm and 4.8 ipm feed rate with a .05 peck and flood coolant. I do run a center drill ahead of it leaving a center about 1/2 or more of the drill diameter. I have...

Running a tight tolerance job on a 4th axis using probing to deal with thermal expansion and help maintain position. Suddenly things are out of whack by .0012 where they should be within .0005. Wiped down the probe and checked it for runout. I found it to be out by almost .0015 and started...

I ran some parts in 304 stainless for a customer. The print had a mil spec for QQ-S-763-D compliant material. The job was a bit of a PITA, but got through it ok and shipped them out. The customer called me today asking for material certs showing DFARS complIance. I called my material supplier...

Im running some parts in 304 with .055 holes in it. The drilling operation is followed by facing. Unfortunately, the burrs around the holes are closing them back up. As you can see, it’s not a simple matter of running a chamfer tool. The holes pierce the surface at a 30 degree angle. Any ideas?

End of the day and I was finishing up an operation when my Miyano JNC-45 up and went lights out. No response from the control. It was in the middle of roughing out a set of soft jaws. looked in the back to find breaker CP4 has been tripped. I reset it, turned the machine back on and it...

Picked up this boring bar for a job and found the standard WNMG 432 series inserts do not fit. They are 1/2" inscribed circle and 3/16" tall, the inserts that do go with this bar are 5/16" thick... (WNGX) After a search through Kennametals site, it seems that all the compatible inserts...

I’ve been looking around at different pallet systems for a while. Trying to decide which systems are most effective for hand loading a VMC with a 4th axis. What are some of your experiences with the different systems you have used? Repeatability, maintenance, versatility, rigidity, ease of...

Running a Miyano JNC45T wi a FANUC 0T control. At the end of the day I hit the power off button and nothing happened. I had to go around the back and shut off the main. Turned the main back on and the machine powered back up without hitting the power on button on the control panel. The machine...

My 5C fixture gave up on me. Of course it happened on a Friday afternoon just as I was finishing a setup for a job that needs to ship Monday. The eccentric pin that moves the collet closing sleeve finally rounded off to the point where it no longer worked. In the process it also ruined the...

I’m running a job doing a pair of bushings in 12L14 with an internal thread (M20x2.5 and M24x3.0). A rather tight bore and coarse pitch. I was planning on running both parts with the same bar and insert to save some tooling and setup cost. I ended up getting a Sandvik Corocut MB bar and inserts...

I was setting up my Miyano JNC-45 today when on a z move it stopped and alarmed out. according to the manual this indicates a “HC” alarm. The troubleshooting guide has instructions to do a simple ohm test to verify if the transistor is faulty. After reading and re-reading the instructions, I...

having issues with chatter and poor surface finish in a woodruff key seat. I’m using a KEO #808 key seat cutter in a Cat40 side lock tool holder cutting 1045 grade material. I have tried different feeds and speeds and am having a hard time hitting the magic combination.
