In this episode of Rottler Featured Series, we’re in McCool Junction, Nebraska home of Donrich Machine a full-service machine shop focused on agricultural and industrial diesel and gas engines.

Corey Schlegelmilch, owner of Donrich Machine tells us he bought the business about 20 years ago, starting out as a one-man shop in a 2,000 square foot building with a handful of equipment. Since then, he’s grown Donrich into a thriving business with a team of employees and a new 7,200 square foot facility.

Being located in America’s heartland it’s no surprise that a good portion of their business is servicing the workhorse diesels that keep the water flowing and the crops growing in the farm fields of the Midwest. Donrich services a lot of engines like Cummin ISXs, CAT C15s and Detroit 60s. To get that work done quickly and done right, they’re using the Rottler EM79 engine machining center along with the H85AX automatic hone and an S80 series surfacer.

According to Corey, one of the big advantages using Rottler equipment is the ability to work on a diesel and then switch it up to machine gas V8 with near zero downtime. Plus, with the increased speed and accuracy of Rottler’s CNC technology, he knows it’s going to be spot on with the machining specifications.

We asked one of Corey’s machinists and told us what he appreciates about the Rottler equipment is anyone can learn it. It only takes a few minutes to master and, unlike other machines, you don’t need to stand there and watch it to make sure it’s working. “You hit the button and walk away,” he said. “You’re free to go work on something else.”

Corey summed it up pretty well. “I’ve been using Rottler equipment since I started in this. They always build a good product, they support it, and you know they’re going to be around for a long time,” he said.

He’s right too. Thanks to customers like Donrich Machine, we’re celebrating our 102nd anniversary this year and we’re looking forward to 102 more!

In this episode or the Rottler Featured Series we’re heading out to Centerville, Utah to visit Dave’s Auto Center, a family-owned business that’s also home to the most trusted diesel and automotive mechanics in the state.

Dave’s began as a plain old auto repair shop over 30 years ago, but has grown to a full service auto center with a CNC machine shop and even a complete line of crate engines ready to ship.

While Dave & crew service the full range of cars and trucks, one area they really shine is in diesel repair and rebuilds. The company always strives to build great product, and one of the ways they do that is investing in the best tools to deliver the best results. And when it comes the the engine building business, the best tools naturally includes Rottler.

Dave’s first piece of Rottler equipment was an F79 (now EM79), multi-purpose automatic CNC engine machining center — a purchase Dave’s president, Miles Bell, calls “the best investment they’ve ever made” in the business.

Since the F79, they’ve also added a Rottler H85AX automatic hone to their equipment line-up, allowing them to setup and walk away while the machine does a wide range of precision work completely unattended!

We’re proud to call Dave’s Auto Center a customer, and look forward to years of collaborative work with this great auto business!

Oh, and make sure to check out their YouTube channel for hundreds of great videos on troubleshooting and repairing all sorts of diesel and gas engines from just about ever engine manufacturer there is.

Nick Cogar works at Diesel Power Parts & Machine, an engine machine shop located in Missoula, Montana. The shop mainly focuses on remanufacturing engine blocks, cylinder heads, crankshafts, and connecting rods among other engine machine processes. The shop owns a Rottler F79A machine that helps keep the shop running smoothly.

“I would recommended Rottler because the machines are very user friendly, and it’s sped up our machining time by 50% or better.”
