Purpose and structure performance:  

    With AutoCAD, the designation of JK31 series presses are fully considering the dynamic precision at high speed, bottom dead center changing, vibration and noise, which makes sure of high quality products at high speed. The efficiency of JK21 series presses is 6-10 times of normal presses. The punched accessories has high precision, the die has long service life, while the press will also save human resource and material. This series presses are appropriate for precision punching and silicon, steel plate, chain, disc spring etc. It is widely used in the fields as electric motor, low voltage apparatus, instrument, light industry. The press is especially used for middle steel plate punching.

Welded H straight frame with quality steel which means good rigidity and little distortion

Square figure and long guide with six friction-faces makes sure of abrasion resistant and stable precision

Hydraulic overloading protector can give die more accurate and quick protection. And the press will recover in few seconds if overloadi

Fixed with friction clutch and brake, closed bevel gear with dipped lube. Slide with counter balancer. Run smoothly and make low nois

Intermittent auto lubrication makes every point get fine and safe lubrication. Long service life is saved

PLC controller makes sure of sensitive motion and reliable performance

Speed die changing, air cushion, photo guard, auto feeder are optional

Infinitely variable speed device is used for adjusting speed.

The frame of A type is strengthening semi-closed structure. The bearings of main shaft and connecting rod adopt rolling bearings. The guide way adopts rolling six faces structure. A type press is more rigid, faster with high precision than standard products.
