CNC Masters understands that many older NC machines are among the best for reliability and durability, but the controlling systems are outdated or simply impossible to maintain and repair. As such, outdated machines are often left in a corner and forgotten. With CNC Masters, an older machine can be revitalized, bringing added productivity and efficiency to any shop. By installing our CNC Vertical Knee Mill Retrofit Kit, any shop can breathe new life into old machines.

Installing our retrofit kits into an older machine improves productivity and efficiency. CNC technology allows machinists to fabricate parts with little interaction with the machine itself, and CNC machines can be programmed to create large production runs automatically. Since the operation of CNC machines is incredibly easy to learn, novices can create complex designs by loading the design into the computer with one single click.

While our retrofit kits are designed to be installed easily, even by just one person, performing modifications on any CNC machine can be intimidating. Our staff consists purely of trained professionals whose main goal is to help our customers. CNC Masters will gladly assist our customers in any way possible, so contact us for any questions regarding your CNC SUPRA Vertical Knee Mill Retrofit Kit.

As with all of our products, we are proud to offer financing for our CNC Vertical Knee Mill Retrofit Kit. Contact us directly – or use the simple online form – for questions or finance inquiries.

Customer Testimonial:

"For those of you out there who are considering a conversion of any Bridgeport or Bridgeport clone knee mill, please allow me to advise you to give serious consideration to the CNC Masters kit. It is a complete kit, and is extremely well-designed with great consideration given to make it easy to assemble with a minimum of work to the mill itself. Working by myself and following the instructions, I had no problems of any kind with respect to alignment or any other issues.

In running the mill, repeatability is as advertised. As is accuracy. My mill is equipped with X and Y DRO, and the coordinates called for on the computer are matched by the DRO indications within 2 to 4 ten-thousandths EVERY time! Measurements of repeat runs are even better than that!

I searched a long time for a kit, and given CNC Masters' design and manufacturing quality, and including ease of conversion, I could not find anything that even came close to matching it. Neither could I find anything close to this price.

Lastly, CNC Masters has been one of the most accommodating companies I have ever dealt with. All things considered, this was one of the best decisions I have made, and a huge step in having more capability."
