Our new Accu-Pro machines are the biggest, sturdiest, and most powerful Sherline machines to date. These CNC machines embody the strength and reliability of Sherline combined with a state-of-the-art MASSO G3 touch controller and a 36V power supply.
We designed the Accu-Pro line with industrial shops in mind. Each machine has ball screws with beefed-up saddles. The line includes an 18″ benchtop mill with an 18″ table, a 17″ benchtop lathe with an 8″ crosslide, and a benchtop chucker lathe with an 18″ base and 18″ crosslide. The MASSO touch controller has a 36V power supply that runs the 36V, closed-loop stepper motors.
