View Full Version : Stuck tool holder, Kwik Switch
08-15-2003, 11:22 PM
I need help! My kwik switch won't release. Does anyone have these figured out? They turn to the right to release don't they? What is the little screw inside the little hole used for? Also there seems to be a little spring plate that moves over the hole.
Facing the machine, using the spanner wrench they release by turning to the left, CW rotation looking down from above the machine.
Do you have the correct wrench? You should get one if not. Heavy milling will self-tighten the holder making hand tool changing difficult/impossible.
Did you crash the machine? If you did it can damage the mechanism. Universal sells a small rebuild kit including a spring and a few other small parts, not expensive IIRC.

I lock my brake, take the hook wrench and pull the collet around to release it. There are drawings in the book of the spindle and lock.
I hope it is not rusted stuck. You have a problem when you handle the adapters about them turning red.

I found a diagram on page 6-3 of manual M-128 that shows a CCW rotation to unlock. Of course it is unclear whether it is to be understood looking up or looking down but I hope I can assume it is looking down. I hope it is correct because I've been applying considerable torque in that direction. Once I get it loose I'm going to have to analyze where it needs a little oil and of course keep the taper clean. Are there versions of the Kwik Switch that unlock in the CW direction?
If we're talking about Universal kwik switch, they unlock CW looking down from above. No doubt about it. Call Universal if you want to verify.

One lil bitty grit in the taper collet or kwik switch can cause the mill to wobble making more junk to throw into the waste barrel. One company makes a plastic taper brush to clean the chuck.
Mine has never stuck, I must be living right.
Have you found tooling yet?

You are 100% correct in saying CW to release.
The Bridgeport manual M-128 page 6-3 is 100% incorrect.
Thanks to you Doc.
My Jaguar automobile expert examined it closely with a flashlight and noticed the ramping inside the Kwik-switch. Let me tell you that this ramping is so slight as to be nearly imperceptible. We used chisels and hammers in a synchronized way to rotate the ring because I had it really really tight.
The Tooling is real hard to find and really expensive. The quest continues. On the M-128 document conversion I sent you, I thought it was much better than it really is. I was using Omnipage pro 12 to convert it. The original conversion file saves both the image file at 300 dpi and the extracted text file. The file in that format takes up 45 Meg for about 70 pages. My computer can’t seem to open it any more as it reports that I don’t have enough memory. I have 256 Megs of ram and lots of HD space. I’m working on it.

KBC handles that brand. Ain't free by a long stretch...
