    Deep precision holemaking in UHMW

    Hey guys. Quoting brought me an RFQ the other day that I shot down on principle, but it got me thinking. So, the part is UHMW plastic. It was roughly 2.5” OD, 37.50” long, and called for a thru hole. 1.250” diameter, +/-.001” all the way thru. No tolerances on runout or straightness, it was a...

    Boring out a lathe spindle

    Hello gents. I have a task at hand and need help figuring out how to do it. We have a Haas TL-2 lathe. For a reason that escapes me, Haas manufactures these machines with a spindle bore of exactly 3.000" - or perhaps even a thousandth or two under. We all know the old adage, a half-inch pin...

    Milling and Grinding HAP-72

Typically, the pieces are made of D2. For scale's sake, each piece approximately 2" long, just over 3/8" thick (10mm to be exact), and...

    How to make a flat part!?

    Hello gents. Our shop struggles when milling flat plates. It is a job shop, so this can mean anything and everything, but perhaps as an average, say something around 4 x 8" long/wide, 3/8" thick. They can be smaller, or much larger. Any material - we have struggled with stainless, 4140 AN, even...

    SL-20 - threadcutting does not sync up

    Gentlemen. I've a serious problem! We have a Haas SL-20, made in 2000. Nice machine. Still holds tenths to this day. But we have had a problem rear its head as of late. The more immediate problem is as such. We are single-pointing an I.D. thread, 7/8-14, in brass. Using a laydown-style ID...

    Help - I need some fast holes in 304SS!

    Gentlemen, I'm in need of some direction. The shop I work at has a part that we are beginning to make a large quantity of, it's getting to the point of a couple of hundred per week. Dead simple part, a 2" OD x 1.885" long cylinder with a non-critical, .562 hole through. But it being 304 SS has...
