 1 . JH21 Series Presses is one of the new generation of plate process and developed by Besco Machinery Limited ,The press is for cutting, punching, blanking, bending and light stretching work.

2.C-Type Steel-welded frame, high rigidity and less deformation Compact,wide body frame eliminating vibration for improved ide life and machine. 

3. Rigid construction guarantees exact die mating,Six-side long rectangle guides of the slide with high moving precision and high accuracy, extending the service life of the die.

4. Highly advanced, rigidly supported gears, operate in oil bath without any noise saves space, reduces, shaft deflection, increases gear life.

5. High accuracy, high efficiency, simple and convenient operation, good performance, favorable price and best service.

1. The Press adopts the low inertia combined dry pneumatic friction clutch and brake from OMPI, Italy, Smoother press performance, easier maintenance, to ensure reliable safety and flexible action,Iow noise, long service life.

2. Driving gear is installed into the frame and gear is immersed in oil reservoir. Customer could choose Electromagnetic governor. which is stepless speed regulation within a certain range and enlarge the area of craf.

3. The press adopts hexahedral rectangle lengthen gib, which has high guiding precision and steady precision.

4.PLC from Omron electrical control system allows various auto-equipment reprogrammed accord-lng to different requirements and perform various functions,to ensure high reliability and high adaptability,

5. Use adopts dual valve from TACO, Japan, which can guarantee the safety and reliability of clutch.

6. Machine is with both hands button and foot switch to achieve continuous, single and inching practices.

7. Auto grease lubrication system,easy stroke adjustment mechanism increases press versatility tremendously.

8. Pneumatic dual balance cylinder, which balances the slide block and punch weight to reduce noise and impact;

9. The press adopts cam controller which be combined with proximity switch (Schneider) which will realize the synchronous detection and monitoring reliably.

1. The RAM is a whole cast form construction which adopts imported hydraulic overload protector from Showa, Japan with agile and reliable action. After overload, it can reset automatically to reduce the down time and improve the availability of press. 

1. Electrical components are imported or from Sino-foreign joint Venture,in accordance with international standards,reliable safety,long life,good anti-interference ability,a radiation unit is fitted in electrical cabinet.

2. Protective fence and the safety interlock to ensure the operation safety. Have a movable single-hand pedal switch,easy to operate.

 Standard Execution:

Heavy, one-piece welded steel frame is designed to resist deflection, providing more accurate stampings and longer die life. 

Fast-response hydraulic overload relieves the pressure of a tonnage overload in milliseconds, stopping the press immediately and protecting press and dies from damage.

Wet clutch and brake provide long life, very low maintenance, and high performance even at high single-stroking rates.
