  1. Hi,

     

    Are you using any lubrication on the puches? You can finish the punch and die to size then heat treat if you like, what kind of clearance are you runing between the punch and die? You should not need any where near 62Rc for Aluminum, I would say 57 to 58. We used to use D2 to stamp 1/4" steel plate with no problems.

  2. Hi James and Lars,

     

    We have a NC4 on our machine with some noted problems. The tools must be clean (no oil, dust etc) so graphite dust would be and issue. The spindle taper needs to be dry and clean.

     

    The Renishaw guy set ours up (we made the bracket out of .25 heavy wall 1.5 x 3.0" tubing). The sending unit and receiver lens need to be cleaned. You need to check the alignment of these by checking the voltage.

     

    We just use ours for measuring the tools since we only do one offs and mostly short jobs.

     

    How old is your NC4 Lars? Any other problems?

     

    The Renishaw guy in our area is a freind of mine so he helps me out if there is a problem.

  3. Hi,

     

    We use it all the time on manual equipment, regular coolant with HSS tools. Run them slower then normal and watch out for chipping of the macor. It is expensive as well almost $100.00 per cubic inch. It is used alot in Ultra High Vacuum applications.

  4. Hi Dragracer,

     

    We have an OiMb here and use a 256 compact flash card, we were told nothing larger than a 512.

     

    Make sure when you format it that it is FAT.

     

    I tried using a 1gig sd card and it would not work.
