    -Seldom used CBN wheels on a SG, company budget driving that choice. Did use CSN almost exclusively on the jig grinder for dowel pin holes and "buttons" or on die sections headed to the WEDM, worked...

    Haven't swapped pins in over 25 years and that should be noted.

    1)"Press In New Ones" can be that simple but like everything it's about how you do it. Simple things are not always simple.

    Can't answer most of your questions but I have machined Waspaloy as molds for Corningware. Not a fun material to mill, particularly with HSS draft cutters.

    One other thing I've been experiencing lately is the program (2014) not launching due to licencing issues. For those that have an older version that's not starting go to the Flexnet listing in...

    I've ground a fair amount of hardened D-2 though usually not as thin as your example. The wheel you're using should be a good enough general purpose wheel but would very much agree that a more "open...

    Can't offer any help on this, just wanted to congratulate you for getting it up and running. Didn't know you had this, nor that purchase price was below retail.

    It would help to state the desired level of accuracy you want. What have you learned from a discussion with Keyence, Banner, or some of the other sensor makers? Did you call the robot/control mfg's...

    Clearance for leader pin to bushing? Having .0004 per side doesn't allow for much movement/clearance between pin/bushing before you're contacting punch edge to die edge. Is there even a bushing or is...

    -You needed what I just described doing with the hose. Make two extrusions that define the start/end points. They can be as short as you wish and can also move, dragging the 3D sketched spline along...

    You'll want a jig borer for the plastic and a surface grinder to refresh the steel. If you have both and the time it's up to you. If not then it's best to buy a new one. A shim punch set is an item...

    Rather unusual results. Are you checking clearance between punch and die with a die light to verify alignment AND geometry? Are you checking the edges of both under magnification for contact or "skid...

    It would be more trouble to do this but you could also make a sub-plate for the bottom of the DH that's doweled in place to the DH. It would use the existing keys to locate to the sub-plate and new...

    In another thread I stated that I had no experience with a seeded gel AO wheel. Apparently Norton describes the "ceramic" wheels as seeded gel and I have used several of them.

    I prefer using SC for roughing (shattered cutting edge) where there's a lot of carbide to remove and possibly running into steel. I'd rather save the diamond for the last bit of geometry/edge. I...

    -Not surprised the Mitsui is more expensive, I felt it was a better grinder and apparently they do too. All the shops I worked at must have felt the same about price and bought the Okamoto for wet...

    Have used several Okamoto wet grinders in that size and consider them a very good SG. From back in the late 1980's a Mitsui seemed to be a better grinder. Nothing wrong with the Oko, just a personal...
