Product Details

J21 series is versatile fixed worktable crank shaft press machine. Among which, the J21-125T is the upgrade product for J23-125T, it adopt one-piece casting machine body, non-inclinable, helical gear transmission, and rigid clutch.
J21Z-125T,J21Z-160T, and JD21-200T all adopt dry friction clutch which can stop the slider at any place immediately, and at the meantime achieve the single, jog or continuous punching operation, which is convenient to adjust the die position at any time, thus improve the machining precision. The whole machine adopts imported PLC centralized control system and equipped with safety dual valve and balance cylinder, which make it work smoothly and reliably. It can also be equipped with photoelectric protection device, it is a safety type press machine.
