The billet grinder automatically loads, grinds and unloads diameters from 75mm to 205mm and lengths from 250mm to 1,550mm. Parts from 100mm to 250mm in length can also be ground but will have to be loaded manually.

After the OD grinding, the machine will automatically grind the end face. Constant grinding pressure is controlled via proportional valves and a current controller. The machine has a Y and an X axis.

The operator can control the grinding sequence via a joystick that allows forward and reverse rotation and left-right or right-left roll grinding head feed. Alternatively, the grinding sequence can be set to fully automated operation with programmes recalled from the Siemens S7 programmable logic controller.

A 40kW motor drives the 400mm-diameter x 50mm-width grinding wheel for OD grinding and a 25KW motor grinds the end face. According to the company, these powerful motors are necessary to guarantee a minimum metal removal rate of 10kg per hour.
