Rottler Manufacturing: The Unsung Hero of Combustion Engines (100 Years of Made In America)

What happens here

The tour moves to the electronics assembly area, where control systems for the machines are built. Cabinets arrive flat-packed, and technicians assemble all internal components, including circuit boards and wiring. The host points out that this machine (EM69ATC) is the first one Rottler built and has been used for five years to test parts, running 10 hours a day to simulate daily use. It's a block-work machine designed to machine engine blocks, capable of precise alignment within one ten-thousandth of an inch.

Goal: Showcase control system assembly and the EM69ATC machine

Tools and materials

  • Circuit boards — Building machine control systems
  • EM69ATC machine Rottler — Machining engine blocks and in-house testing of machine components
  • Wiring — Connecting electronic components within the control system

the same frame as the HP um the HP is the 5x it's the only difference you have a five axis articulating head and that's in the back but they're all built all these machines are built assembled right back in uh the left corner here this is one of our last manual machines um for the Rottler f80 series mid 80s we went into the big diesel market and we've always had a traveling column our large format machines with uh highly Precision ground spindles and so we've kept this manual grinder in t here always does a fantastic job of hitting every number and we track each spindle which is really cool so we have an inner and outer spindle assembly and we'll track each dimension on every machine that it gets assembled so whatever that got ground at and we record that information because we make our own tooling our own right angle drives this is a piece here if I if I rattle it there's a little here that little yeah you want to you want to make sure that you hear that all the time because what this does is when this thing's boring this this makes it so the cutter head doesn't chatter which was a again a great simple little design it made the machines better and when a customer wants to order a new right angle drive because it clamps on that spindle we have to have that number that that diameter of their machine to uh to match it so see the master of using this machine he is the master of this machine how long have you worked here I'll ask him hey T how long have you been with Rottler 19 years 19 years because you're the master of the spindles that's what we're talking we're talking you up that's all I got here that's right thanks Steve you can get right angled rise from the general Machine Tool industry but none of them will fit in to an engine block to allow you to
