Frame adopts overall welding structure, and the vibration aging treatment, the machine tool accuracy keep sex is good. Hydraulic lift, stepless voltage regulation, using high quality imported sealing ring, to ensure the reliability of the machine tool. Mechanical synchronous, adopts the compound compensation structure, improves the processing precision of parts. After the stroke adjustment and profile had a adjustment, by electric adjustment and manual fine tuning, and fitted with digital display. Machine tool is a little movement, a single, continuous operation rules, reversing, the holding time should be controlled by time relay.
