1.whole structure of the Pneumatic Punching Machine JH21-45Ton
● JH21 Series High Precision Presses is one of the new generation of plate process and developed by BAMBOO. ,The press is for cutting, punching, blanking, bending and light stretching work.
● C-Type Steel-welded frame, high rigidity and less deformation Compact, wide body frame eliminating vibration for improved ide life and machine. 
● The press adopts hexahedral rectangle lengthen gib, which has high guiding precision and steady precision.
● Highly advanced, rigidly supported gears, operate in oil bath without any noise saves space, reduces, shaft deflection, increases gear life.
● High accuracy, high efficiency, simple and convenient operation, good performance, favorable price and best service.
● The machine by the European Union CE certification and ISO quality system certification.
2.Controller System and Cluth
● 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.
● 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.
● Use adopts dual valve from TACO, Japan, which can guarantee the safety and reliability of clutch.
● Pneumatic dual balance cylinder, which balances the slide block and punch weight to reduce noise and impact;
● The press adopts cam controller which be combined with proximity switch (Schneider) which will realize the synchronous detection and monitoring reliably.
