One thing to keep in mind if your soft Jaws are not parallel and square when you clamp them with the spider it will transfer, just like cutting lathe jaws the better your spider/ spacers are when cutting the jaws the better your jaws will be. If it is time for a dust up on a surface grinder.Ĭheck the movable jaw for burrs nicks etc etc hit it with a stone see if its even. Other thing to do is move the jaw back and tight screw see if that locks the jaw.

Your need to clean the thread better, Chase it with a tap etc, make sire your screw is clean and goes in all the way free freely.
I am curious what Kurt will say when I finally get a hold of them.if you cant tighten the threads down(with out a cheater bar) and you can still move the jaw back and forth you have one of 2 problems Thanks for all the help it got me going in the right direction. I have another set of older D688 vises on my Trak bed mill I think I will swap them out for these I don't use the Trak very much anymore since I got this machine. I can tighten that set screw as tight as I can get it more or less don't want to strip the threads I can still turn the vise handle with just a little resistance if I did that to the other vise you wouldn't be able to turn the handle. Tore the vise down again wiped out all the old grease and blew it out again and put new grease on the half moon part. I did as you said and used some gauge blocks to space out the jaws and cut the step again. Other thing is that could be happening if your endmill corner is nicked so the part is hitting on the inside corner of your step.Thanks I will give this a try. Other thing is that could be happening if your endmill corner is nicked so the part is hitting on the inside corner of your step. same when using a spider so to speak it has to be square. cut the jaws and you should be fine.Īlwasy dry to clamp a spider so to speak as close to the same size as your part other wise if you have any wear in the base you will get lift at different lengths.Īlways tighten the screw so the movable is snug not tight in the area you are going to clamp as you may have movable jaw wear.Ī tip on Jaws and clamping, if your jaws are not parallel and square to the movable jaw and fixed jaw your vise wont seat square when clamping on a part.
Use a square stock jaw for a spider so to speak. move the handle back and forth while tightening the screw till its snug to turn jaw. Put a dab of geese in the moon then put it back together. clean it well including the threads for the tightening screw. take the screw out and the half moon out. Your problem is cutting the jaws, your doing it wrong!! NEVER clamp the 2 jaws together.ġst thing I would do is take vice movable jaw completely off. I have a call into Kurt but they are not going to get back to me until Monday and I have work I want to do.Īny suggestions are appreciated.022 is alot. I have checked the half moon disc it is clear of chips and is greased. I used a Tschorn probe to get my readings. I have checked my machine bed and the vise bed both are right on the money. Left vise is fine but the right vise lifts too much. I give the jaws a wrap as I am tightening them with a dead blow hammer when I use them and also before I machine in the step. I mill the step in with the jaws clamped together. Here is my setup I have some shop machined soft jaws 6061 T6 with a step milled in. I have cleaned and adjusted them both no matter how I adjust this one vise it always lifts way too high. 022" jaw lift when it has 4" stock clamped in the jaws. I have a pair of Kurt DX6 vises I use in my Sharp VMC.
