The special construction of the Multi Grind makes it possible to combine the functions of cylindrical, flat and tool grinding in one machine. With external cylindrical grinding, the workpiece is either clamped on one side or supported between centers in the stable tailstock. An internal grinding device can also be attached to the headstock and light surface grinding work is also possible with this model. With the additional tool grinding function area, you can use the Multi Grind to machine the cutting edges of a large number of tools.
