Centroid CNC Retrofits Featured in Modern Machine Shop Magazine

From the May issue of Modern Machine Shop Magazine "A CNC retrofit provides improved reliability and functionality compared to an older machine's original control, and this is helpful in a number of ways. For example, a more intuitive control interface can help speed setups and minimize the chance for programming and/or setup mistakes, which could possibly damage or scrap a high-value work piece. Similarly, shops are also more confident in quoting work for large, expensive parts knowing the new control won't hiccup partway through an operation and cause the part to be damaged. Shops also are better-positioned to take in ''hot'' jobs that require fast turnaround due to the retrofitted machine's improved"... click here to see the complete article in PDF.

CNC retrofits for Milling machine, Lathes and Routers

"The quality and workmanship of the CENTROID equipment was outstanding and very professional. CENTROID was able to custom tailor the control to allow us to continue to use our rotary milling arrangement as before and even expanded our capability. The short story is that we ended up with a four axis CNC mill for less than half the cost of the three axis Haas. This includes the work that was done by our staff."
