    If you rough machine them and then have them annealed and normalized they will move around much less after final machining and heat treat.

    That oil will be just fine. If you have a lot of parts to do and you are using a single stone mandrel, consider getting a metal bonded borazon stone. The are not cheap, but they cut fast and seem...

    Remember he is on a CNC lathe- no quill clamp, n handwheel etc. And then again, sometimes its just easier to admit you need to grind the darn things as a 2nd OP.

    I understand Mud's point, but make sure you don't create a 2nd problem fixing the 1st one. The center line between the center of turret rotation and the tool tip or center of an ID tool holder MUST...

    Assuming its a random access tool changer, how would you know what tool is in what pot if you don't call it by tool number? Are your programs written to always put a tool back in the same pot it...

    That's a CTU for sure. Mine had a 2" wide wheel on it, but the wheel mount would take a 1" wheel with no modifications. The fine feed handwheel is .004" on diameter per turn and is nice for...

    Do you have a parts book? The turret is positioned by a curvic coupling pair in most machines. One side of the coupling is bolted to the turret body, the other half to the tool turret. Most likely...

    One other thing to try-put a slight dwell on the center drill to make sure you get an accurate surface.

    I have a 6 x18 Norton CTU and its not a light duty machine- more of a production grinder- not universal. It uses a 20" wheel. Wheel head bearings are plain type and run just fine. Its a little...

    I did not say it was good for you, just that it's a great solvent for acrylic.

    If you don't like the Protrak mill stuff you will hate the lathe stuff. A friend has one at his work that they inherited from a sister division and its a true POS to program and he hates it and now...

    Just about 100% sure you cannot fusion weld cast acrylic sheet. It works great for polyproplyene but not acrylic.

    If you're worried, put a lathe dog on the body of the drill in front of the taper and let it rest on a bar clamped in a toolholder on the cross slide. A long boring bar works pretty good for a rest...

    Get some methylene chloride and a small syringe or the little solvent bonding bottles that tap plastics sells. Set your joint up and flow the meth into the joint by dragging the needle tip along the...

    If your tolerances are real, and need repeatability, honing would probably salvage a lot of your scrap. A few swipes on a hone and a few tenths later you would have a perfect finish and to size.

    If the machines are inside a building, using an air arc or oxygen lance might lead to an undesirable situation.

    Yup- Dave is a great resource. There are a bunch of 40 year old Hurco CNC mills out there still running because of Midwest CNC and a few other dedicated suppliers. AFAIK, all the Hurco Knee mills...

    You might check with Midwest CNC Service for a good used ballscrew and nut. They are Hurco guys, but the iron is the same.

    We spent 30 years cleaning up the trash that others spewed on the sidewalks in front of the shop. It's gotten so bad now that we just leave it there and call the city to clean it up. Takes a few...
