The frame is entirely welded with steel plates and treated to relive stress by tempering, so the precision is well maintained. 
Hydraulic top-drive, stepless pressure adjustment and high quality sealing rings imported from overseas to ensure the machine tools reliability. 
Mechanical synchronous mechanism and the complex compensation are designed so as to raise the workpieces precision.(the convex structure for the table above 160T) 
The stroke and distance of the backgauge is adjusted by the motor and is well adjusted by hand, the adjustment is displayed by digital meters. 
Inch,single,continuous operation mode being designed for the machine and reversing and maintain time can be controlled by the time relays. 
Safe fence and the electric interlocker have been designed for the machine to ensure the operation safely.(the back of 40T and above 200T without safe fence)
