Specifications

JH21 SERIES
HIGH PRECISION POWER PRESS

Standard Equipment:
-JH21 series high precision presses is one of the new generation of plate process and developed by OHA.
The press is for cutting,punching,blanking,bending and light stretching work.
-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.
-Highly advanced,rigidly supported gears,operate in oil bath without any noise saves space,reduces,shaft deflection,increases gear life.
-The press adopts the low inertia combined dry pneumatic friction cluth and brake from OMPI,Italy,Smoother press performance easier maintenance,to ensure reliable safety and flexible action,low 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.
-Auto grease lubrication system,easy stroke adjustment mechanism increases press versatility tremendously.
-Pneumatic dual balance system,easy stroke adjustment mechanism increases press versatility tremendously.
-Pneumatic dual balance cylinder,which balances the slide block and punch weight to reduce noise and impact.
