JH21 series C-Type high precision power press 1.JH 21 Series
high precisin presses is one of the new generation of plate
process. It is for cutting ,punching ,blanking ,bending and light
stretching work.2.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 die3.Highly advanced, rigidly suppported gears, operated in oil
bath without any noise saves space,reduces, shaft deflection,
increases gear life.4.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, low noice, long service life.5.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.6.The RAM is a whole cast form construction which adopts high
quality hydraulic overload protector and reliable
action.After overload, it can reset automatically to reduce the
down time and improve the avaiability of press.Main
