Tool pull out on Threadmill
Using the calculations I ended up with 4.6IPM as opposed to the 14.8IPM, the threads do seem to have less chatter now.- pitnut

Tool pull out on Threadmill
Just quick update. I swapped my radial drill and thread mill so I could hold the extension with a set screw and flat. The drill went into the ER32 with a different size collet and everything seems to be holding position now. I think there was something wrong with the collets, they are of...- pitnut

Tool pull out on Threadmill
That makes a lot of sense to me. I am forced to use the collet in the live tool holder but I will try to find a more rigid holder for the TM with a set screw?- pitnut

Tool pull out on Threadmill
With a sort of solvent, no just air blast. I will do that. As for the torque wrench, I don't have access to one that would work with this holder. I understand over-torquing can be just as bad if not worse than under-torquing?- pitnut

Tool pull out on Threadmill
Hello all, I am currently working with some 6061 2x2 square stock in a Haas DS30. Right now I am having a problem with my Thread mill (morse 1/4-18 NPT) (https://www.morsecuttingtools.com/catalogue/product/321272) pulling out of its holder. The tool sits in an ER25 collet which is fine, but...- pitnut

Haas DS30 Running with nothing in chuck
That's a good call I didn't think of that, I get a bit of a feed line when I drag my part off tool out. going to start painting the last two feet of the bar red as well- pitnut

Haas DS30 Running with nothing in chuck
Thanks for all the replies guys. I’ll just have to tend to the machine. The questions stems from me doing a synchronized part off with the sub spindle but on the last piece it tries to part off with the workpiece like 1/8” out of the main chuck which is spinning around 2k rpm. Don’t want to risk...- pitnut

Haas DS30 Running with nothing in chuck
Is it normal for a cycle to be able to start with nothing in the chuck, but the jaws clamped? I know on Okuma I can move the proximity sensors in the chuck but everything on the ds 30 is paneled off. Would they have any names other than proximity switches, I haven’t been able to find much by...- pitnut

Multiple offsets for one tool
Thank you for all the replies guys. The question did arise from a program/drawing with asymmetric tolerances. I agree that changing it in the program is the best thing to do, and I share the viewpoints with others about having multiple offsets for different machines as well as adjusting wear...- pitnut

Multiple offsets for one tool
Is it common practice to have one finish tool with multiple offsets to adjust wear for different features (mainly holes in this scenario) We would do this in my old shop but in my new one this is said to be bad and every tool should have only one offset but I haven't gotten a reason as to why...- pitnut

Tail stock or or chuck clamp first?
Do you say that because of the PSI or my worries of it pushing in? What would you normally recommend if it is the PSI? I am running fan blades so they wobble pretty bad in there and I’m cautious of lowering my pressure. I’m running off of 10 year old set up sheets with little guidance. I’m... -

Machining Chrome encased shafts
Transverse. I ended up taking the chrome off with an HSS endmill and then ripping through the 1045 core with a 1/2" carbide drill. Thank you for the replies guys! -

Tail stock or or chuck clamp first?
I ended up using a bolt threaded through my spindle liner plug. Thank you for your reply! CNC, its an old okuma. Thank you for all the replies guys! -

Tail stock or or chuck clamp first?
Is it okay to clamp down on a part before engaging the tailstock? I can only grab onto a small portion of the part before a taper messes up the axis of the part. I’m just worried about the tail stock pushing it further into the chuck. 175 tailstock psi 200 chuck psi gripping aluminum with hard jaws -

Machining Chrome encased shafts
I am making a .505" hole through a 1.125" diameter chrome plated drive shaft. I've decided upon using a 1/2 carbide drill with no thru coolant and then opening up the hole to the final diameter. I am a little unsure of what feeds and speeds to go with. I did one drilling at 1511 rpm and...
