JY21 Series D-frame Single Crank Press with Fixed Table

Product Features
1. Although with the same welded steel structure as our C-frame double crank press, this single crank press has higher rigidity due to the D-frame design.
2. With alarming function, the automatic thin-film lubrication system allows the metal forming machine to work smoothly all the time.
3. The D-frame press supports electrical adjustment and digital display of die set height, which ensures great convenience in die set adjustment.
4. The D-frame single crank press will automatically stop when there is hydraulic overload condition. Thus, the safety of both the dies and the machine is guaranteed.
5. The eight-surface guide features very long guide way, and also enables the slide to move accurately and stably.
6. This machine tool adopts dry type pneumatic friction clutch to ensure low noise and easy maintenance.
7. PLC centralized control system offers operation modes such as emergency stop, inching, single-cycle operation, and continuous operation.
8. The optional configurations for the D-frame single crank press include the air cushion, transmission output shaft, automatic feeding system, photoelectric protection unit, etc.
