HIGH PRECISION FOR SHEET METAL PUNCHING AND STAMPING

The press body is milling and boring by PAMA machine center and all the surfaces and holes will be finished machining in one position. JH21 C frame press uses rectangular type lengthened slide guides with bronze plates for higher guide precision.Table surface is grinded by high performance grinding machine for better flatness.

Slide adjustment precision is only 0.1mm (for 60ton press and bigger models).

Crankshaft is under roller pressing treatment for better roughness.

Gears are grinding, high precision and lower noise.

WET TYPE PNEUMATIC CLUTCH AND BRAKE

Wet type pneumatic clutch with imported clutch disc, NOK seals, lower noise and maintenance cost, longer service life.

JH21 Power Press with pneumatic wet clutch can work as continuous, inches or single stroke, more choices for operators.

Hydraulic Overload Protected Pump

The press is standard equipped with Japanese SHOWA hydraulic overload pump. Normally

the system is set as 110% of the nominal capacity. The press will stop immediately once it is overload than 110% to protect both the press and the die. It is easy to reset the overload as there is a reset switch on the control panel. The system can be reset within 3 minutes.

Panasonic or Omron or Schneider PLC

PLC control system can be Panasonic or Ormon or Schneider brand.

HMI FOR EASY OPERATION

HMI according to the working time or working stroke times.HMI with setting function, I/O monitor, counter and preset counter.

The press has both mechanical and electrical cam controllers.It is easy to set the cam angles to match the press with automatic feeding system or transfer system.Motorized slide adjustment with digital shut height indicator, precision is 0.1mm.
