“CNC Retrofit” Often Means More

This video testimonial provides an inside look at the myriad benefits Major Tool & Machine has realized from a new CNC platform—but like other, similar projects, implementing that platform required a complete motion system overhaul.

Faster, more intuitive programming, reduced setup times, improved flexibility—these are just a few of the results of Major Tool & Machine’s move to  a new CNC platform for many of its largest machine tools. The video above, produced by Siemens, provides an overview of these and other benefits.

However, realizing these advantages involved far more than just a CNC swap. In fact, most large-machine retrofits do. That was a major takeaway from a series of conversations I had with Doug Huber of Indiana Automation, the company that performed the retrofits at MTM. In this article, Mr. Huber describes why projects like the one at MTM not only tend to necessitate new drives, motors and other motion system components, but also present opportunities for more substantial improvements. 


  • Gearing Up to Make Big Gears

    Over the years, this Indiana job shop/contract manufacturer developed a specialty in gear making. Now it is taking this specialty to a grander scale. Two large machines for high-precision internal gear grinding are the main anchors of the company’s new precision grinding room.

  • Turning The Long And Difficult

    This shop has made large turning work its specialty. In proving to its customers that it can perform this difficult work, it has started to win more "standard" machining jobs.

  • No Need For Speed

    In this shop, high speed machining makes sense at 4,000 rpm. While the disciplines the shop put in place made a new 15,000-rpm profiler dramatically more productive, high speed machining would have remained valuable even if the new machine never came. Acoording to a co-owner of this shop, high speed machining has no need for speed.
