    Predictability is one of the most important drivers of cost reduction in manufacturing.

    Classic tortoise vs hare.

    Without looking at the exact numbers, my guess is that Stressproof is going to fall slightly short of the requirements.

    Horizontals can be a bit tricky with the weight balance. Riggers make it look so easy.

    I get anxiety just thinking about moving one of these myself.

    Not that many, so I'd just baby it for the last half.

    Reduce the peck, slow down rapids, and keep your R plane high enough to so you can maybe rig up an air blast.

    Tapered jaws are a good idea.

    Aluminum jaws will get chewed up from the hardened steel chips, but since this operation does not require precise location in X and Y, it shouldn't matter. You'll...

    If this is a CAT40 holder, a short piece of rod can be driven from the back with a 5/8"-11 screw.

    Don't burn yourself. Assume every piece inside the holder is piping hot, and take your time. It...

    Rolled plate is always hit or miss.

    5/8" is very thin.

    The slot in the middle of the plate doesn't help things.

    Is this your own design or someone else's? The first thing I would do,...

    Trial and error is the name of the game when it comes to hardmilling with insert cutters.

    Some ideas to try:

    - Use a high-feed mill to rough out most of the material

    - Roll your lead-ins and...

    It's all about heat.

    Tools will cut metal at virtually 0 SFM. Think of a hand tap. But the finish can be pretty bad and they're not very efficient.

    So let's take turning a piece of 1018...

    It's possible they may have tried that and found the guides not to be the bottleneck.

    One of the easy-gets with linear guides is just to space them out further.

    For your particular application, I like Sandvik cutters with the biggest insert available, the coarsest flute count (i.e. 3 flute for a 2"), and a...

    What are you currently using?

    That 9.5" depth is a concern. Maybe look into Sandvik Devibe bars.
