Servo Products Co.’s Orion CNC Retrofit kits add or upgrade no longer supported controls for knee mills and lathes. The pre-configured retrofit package is marketed as a plug-and-play solution featuring a programmable logic controller, VFD spindle speed control, true servomotors, ballscrews and auto lube pump. Users can add an optional LED work light, wireless MPG pendant, power drawbar lockout solenoid and dual-channel emergency stop.

The retrofit kit is said to turn a manual knee mill into to a three- or four-axis CNC machine. Though the milling machine kit is designed for three-axis machining, it is pre-wired for a fourth axis and thus is easily upgradeable. The third axis can drive the knee for a full 16" of travel up/down.

With the servomotors built in, implementing the retrofit system is as simple as installing power feeds the company says. The 400-W true servomotors provide up to 300"/lb of torque and a maximum rapid travel speed of 105 ipm. Servo also offers Elrod belt-and-pulley style systems. Both systems operate on 208- to 240-V single-phase power, making them suitable for small to medium-size job shops.
