I would like to know the proper use of NoGo thread plug gages. My customer contacts aren't around today so I can't get the standard from them, it's not on the print, and I don't have it. That's some important information I need obviously.
The production manager believes the part can make up...
I have this machine that is threading tapping lock nuts at a defect rate of ~1800 PPM. The thread perpendicularity spec. is .005" and the majority (85%) of the parts fall within the lower half of that.
I've attached a picture of the machine, it has a loading station, chamfering, tapping, and...
(Like toolingu.com)I was wondering if they actually work and couldn't find any reviews about them. I have the mathmatics and used to know G&M codes, but after not really using it for 5+ years, I've pretty much forgot.
I'd like to take a lab coarse or something around here but finding one...
I have some 2.25mm thick parts, ring shaped, 1020 steel, that are warping after heat treating.
Case hardening spec.
Nitrocarborize 0.01 to 0.03mm Dep compound depth zone
surface hardness 60 Rc min. (file hard)
Diffusion layer depth 0.15mm min.
oil quenched
The parts are flat (w/in 0.015mm)...
I've got a 55 mm circular part, notched on the OD in 4 places, with a 40.6 mm hole threw the middle. The hole requires a M42 x 1.5 D9 thread. The tap I tested is 6 flute (straight), TiN coated.
I may be running about 100 RPMs fast as the machine only has two speeds.
I keep getting a rather...
