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.
A coolant nozzle is installed on the top of the tailstock for cooling the center tip. An air floating devise allows for smoother movement and protection of the table. It is capable of slightly adjustment and no need to reset dressing zero. -An optional tailstock quill travel of 50 and 75mm helps to load/unload the workpiece with ease. The quill is oil-bathed to ensure smooth movement. -An optional tailstock taper adjustment feature allows the operator to easily adjust for taper error.
The box structure design, the thickness of the frame and rail ribs of this table are 25mm, and the remaining 20mm, can show the best rigidity and stability, and ensure the grinding accuracy and quality. The clean and cool water pipe of this machine is arranged inside the machine, and there are three water outlet holes on the table, which is convenient and beautiful.
The hand scraped Double V guideways provide maximum support to the wheel head for greater stability and grinding capacity. This design insures superior accuracy over the life of the machine.
Positioning by two-piece tooth type clutch gear and hydraulic brake. It is high positioning accuracy, able to hold heavy-duty working, and good water-proof.
ID grinding spindle of T3 axis is designed with built-in spindle. It not only reduces the space, but provides steady torque and rigidity. (Opt.)
T1 and T1 share a spindle. NN bearing designed work spindle ensures rigidity and accuracy while grinding, and provides a bigger output power to increase grinding efficiency. (Standard line speed:45 m/sec)
