Our CNC machines are among the most popular tools in the space. Our current machines are not suitable for machining tough materials such as steel and cast iron and are limited in their ability to machine non-ferrous metals. While our current Bridgeport milling machine can work with tough materials rather well, it is a manual machine which makes intricate parts tedious and sometimes impossible to produce.

For industry, aging electronics often makes older CNC machine tools obsolete before the mechanical parts wear out. These machines can be inexpensive and if mechanically sound, are good candidates for electronics retrofits. Replacing the CNC controllers provides the reliability and features of a modern machine at a small fraction of the cost of a new machine.

This proposal is to buy an older CNC milling machine in good condition and replace the majority of the electronics with modern parts. This will likely include the motor drivers, rotary position encoders, and CNC controller. Depending on their condition, we will try to reuse the motor power supply, switches, spindle and axis motors.
