    Depending on the size of the work-piece my vote is for a Willemin 701S if the parts are really tiny or a 301S2 for bigger parts. They can effortlessly handle the tightest tolerance microwave parts...

    I really like the Swiss DERO vises. They're Lang quality at a bit lower price point. I have an HRK-UKB on my Koma 5-axis table because it has reversible master jaws for more range and serrated...

    Yeah, I wouldn't do that very often. The torque curve on my spindle is barely getting started at 5000RPM. At only 2500 I would not be surprised if you stalled the spindle shattering that endmill. ...

    What's the point of an HSK-40 spindle that doesn't go 42,000RPM...all of mine do? Even the ISO spec for HSK-40A is rated to 30K. Using a high speed holder to rough at 27K or lower is a recipe for...

    I only use multi-axis linking for drill toolpaths. But my machine is fast, has a really tiny work envelope, and the manufacturer has built in approach/retract macros for milling. Are you setting the...

    I can't be very specific about the parts on the 308 but it's a combination of prismatic features in 3+2 and full 5-axis surfacing. My point is that it's dramatically lower labor and faster to make...

    You greatly overestimate the real world precision of machine tools based on the spec sheet. The 308 is a legitimate four decimal places in metric machine but it's not infinitely rigid. Everything...

    Since we don't actually know what the parts are other than desktop mill sized I'm going to weigh in on the other side of the price point argument. The best prototype machine is a fast and extremely...

    MIM is way more involved than than just the mold design. The setting fixtures for bake out can be more involved than mold itself.
