    I form tap harder materials all the time. 17-4 mainly, up to H900 (low 40's Rc).

    I have one part in 36CrNiMo4 QT (4340/EN24) that I form tap M8, made about a thousand of those in the last year or...

    That is a large amount of displaced material - that amount of indentation is absolutely going to have a significant negative effect on the load distribution on the stud and the ball carrier.

    One of our Hurcos has an analogue drawbar sensor. It's a 2011 machine with a Kessler integrated motor spindle.

    I'm sure there is nothing wrong with the DIN mount. I'm pretty sure about every machine on the floor here has sprung latched din mounted components of some form or other. I've never had one come...

    I sort of did, sort of didn't.

    Everybody is moving in the same direction now, by the time I come to replace FC, I am not expecting there to be any perpetual options anymore.

    Make a spider that fits inside, put in three jaw chuck clamping on the spider so the chuck does not collapse the part. Machine the bayonets between the jaws.

    I did this years ago on a 40 taper spindle and had great results too, but I don't think I would do it for just a few high spots. Especially not if there is a spindle grinding outfit 30 miles away, we...

    There was never really a "prosumer" cam market, and the lower end cam market has been all but taken over by fusion.

    Didn't see this the first time around, but if that's your day to day work you should probably not be looking at basic 40 taper VMC's. None of them are going to have the spindle torque to do that...

    I was a bit taken aback by the x rail configuration as well. Why they did it is pretty obvious; inverting the rail like that means the rail is much shorter and you can do away with way covers...

    That doesn't mean the rest of the industry is standing still. New things do appear every now and then that require software support. Minor...
