CENTROID Bridgeport Boss CNC Retrofit kit installs in 12 hours!
Boss 5 before retrofit... 12 hours later, new CNC control and making parts!
         
They just don't make a knee mill as stout and accurate as these old Bridgeport Boss machines. Centroid has developed a special control just for these classic Bridgeports. A Centroid CNC will turn your Boss back into a money making machine.

The old original NC controls on these Boss machines are obsolete, troublesome and never realized the full potential of this great machine. Time for a Centroid upgrade! For just a few dollars a day you'll be making parts you thought you never could.

No one has more experience retrofitting Bridgeport NC machines than CENTROID.

  In addition to all the great CNC features that you get with the CENTROID, After the retrofit, your machine will be faster, more accurate, quieter and will take up less floor space. This machine was retrofitted in 12 hrs including removing the old control. With a CENTROID retrofit, you will be up and cutting parts, making money in a matter of days. We get the job done fast because our CNC controls, unlike most others, are completely factory assembled ready to install.

The new direct bolt up CENTROID servo motors are more powerful and much more accurate than the old Boss axis motors. It just takes a few minutes to unbolt the old motor and install the new CENTROID digital DC servo motor in its place. All mounting hardware, belts and pulleys are retained. The new motors are also quieter and run much cooler than the old motors.

"I am writing this to thank you for your work on the Centroid retrofit of the Bridgeport series 2 mill. I must admit when you first approached me about this, I was somewhat skeptical. My initial thought was that this would be a problem from an electrical standpoint and that I would be much better off with a new machine.

After purchasing a new Haas TM2 and finding that the rigidity of this machine was not totally satisfactory, the Bridgeport project was back on the table. The Bridgeport was in good shape even for its age and we decided to go ahead. This approach also allowed us to keep using the Bridgeport for several jobs requiring helical milling with the Bridgeport right angle head, which we did not have a viable work around for.

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.

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 new motors are much better than the original motors with much higher torque. The operator interface is a much improved as well.

I would recommend this option to anyone that has a decent Bridgeport with tired electronics. This is a very good value for a very capable machine tool."
