Disc Grinder Retrofit Upgrading to a CNC

The grinding company searched for a replacement unit, but found that prices were too high. Looking over their Besly DH6 disc grinder, they concluded its condition was superb and they could save money by upgrading to an automated retrofit kit. The grinding company found MachMotion’s grinder kit and called to get a quote. The company had a few major concerns about retrofitting. Would they lose some or all of the grinders features? How much would it cost and how long would it take?

MachMotion has been doing retrofits since 2002 and knew what to expect, allowing for a confidante quote over the phone. The grinder company couldn’t believe how low the quote was and thought for sure there was a mistake. To assure there was not a mistake in the quote, MachMotion sent out a technician to the company's location. After the visit MachMotion confirmed the price, giving the grinder company the confidence to proceed with the retrofit.

MachMotion was able to build the Besly DH6 disc grinder retrofit kit in three weeks. The machine was installed with a 17” control touchscreen, conversational interface, Yaskawa dual loop servos, and Newall scales. The customer asked for it and MachMotion delivered on their promise!

MachMotion stayed on site until parts were running off the grinder and the customer was happy. They programed both the machine and software, as well as training the employees. The grinder company was left fully confident in how to operate the machine effectively. This is what you can expect from MachMotion with no additional costs.
