1. Blade frame

The blade frame adopts the fixed clamp (4 pcs)

 

1. Main shaft bearing and lubrication system:

The main shaft of this machine adopts precision domestic famous brand bearing with small clearance, high precision and high rigidity structure design. The spindle assembly is corrected by high precision dynamic balance, and the spindle has good rotation precision, high speed, low vibration and low noise. The use of the first international brand oil cooler for lubrication, so that the spindle bearing lubrication is fully in place. Keep the spindle temperature constant. (the system will alarm automatically when the oil pump of the oil cooler has no oil.) it is recommended that the buyer use No. 2 or No. 5 spindle oil.

1. Rotary plate for unloading the material:

After the processing is completed, the cylinder drives the flap to bring the workpiece into the assembly line (semi-automatic, manual), which is suitable for short gas cylinders and long gas cylinders. The carriage device can be adjusted up and down by manual worm gear (it can be fine-tuned up and down according to workpieces of different diameters), and it can also be manually adjusted back and forth to adapt to workpieces of different lengths. The total length is 600MM, 4 rollers, (the foot of the bed reduces a stiffener)
