Oil-bath tail stock remains lubrication and makes the machine more durable. Tailstock taper adjustment feature makes workpiece setting faster.
NN bearing designed work spindle with high power motor provides enough power to outer diameter 510mm of wheel head, and improves processing efficiency. The angle of wheel head could be choose as 0 or 20 degree.
The structure of cross slides is made of Meehanite cast iron. Its good thermostability compensates for temporary temperature changes. (Roller bearing and straight lead rail with Heidenhain linear scale)
NN bearing designed work spindle offers heavy duty load capacity, optimal rotation accuracy, and high rigidity. The servo motor drive offers steady speed and torque during the grinding operation. A positive air purge system keeps grinding swarf and coolant out of the work head, thus it prolongs its life.
Bath type of machine base is made in Meehanite cast iron, which experience natural aging and twice stress relief to make machine base itself more stable and durable.
