(Please not that this is the CNC ready version and it cannot be used manually until stepper motors are installed, which are sold separately) Sherline Products is proud to introduce its latest Vertical Milling machine. With the increase of popularity of Sherline mills in industrial, laboratory and school training environments, the need to produce larger parts has led to the development of an extended capacity milling machine. Sherline’s NexGen Mills are available in Manual, CNC-Ready, and full CNC configurations.
