JH21 C frame 80ton form mold pneumatic hydraulic press punch machine hole punching press machine

The model described is an 80-ton C-frame press, designed for medium to heavy plate processing tasks such as cutting, punching, blanking, bending and light stretching.

The JH21 Series is versatile and suited for cutting, punching, blanking, bending and light stretching of plate materials.

It uses a C-type steel-welded frame that provides high rigidity and minimal deformation. The compact C-frame reduces vibration, improving accuracy and prolonging machine life.

Precision guiding is provided by a lengthened hexahedral rectangular gib, which ensures accurate alignment of the slide and stable, repeatable operation.

The press uses a low-inertia combined dry pneumatic friction clutch and brake from OMPI (Italy), delivering smooth engagement, easy maintenance and reliable safety.

The JH21 Series is primarily a mechanically driven press with pneumatic control elements (clutch/brake and balance cylinders). If you require hydraulic actuation or additional hydraulic features, consult RAYMAX for available customizations or model variants.

The driving gears are rigidly supported and operate submerged in an oil bath inside the frame. This reduces shaft deflection, lowers operating noise, and improves gear longevity.

The press includes protective fencing, safety interlocks, front-side covers with switches, backlight safety guards (Category-4), dual-valve and pneumatic dual balance cylinder, and meets CE electrical standards. Controls and emergency stop features comply with relevant safety and OSHA-style hand/foot control requirements.

The electrical panel uses SIEMENS automation and electrical equipment and incorporates a cooling system. Synchronous detection is handled by a cam controller and Schneider proximity switch. Control options include two-hand buttons and a foot switch.

Yes — the standard design uses mechanical gearing, but customers can opt for an electromagnetic governor to enable stepless speed regulation.

Yes, the JH21 Series is equipped with an auto grease lubrication system to ensure consistent lubrication and reduce routine maintenance tasks.

Routine maintenance includes checking and replenishing gear oil in the oil bath, servicing the pneumatic clutch/brake, inspecting the auto-lubrication system, verifying safety interlocks and guards, and periodic inspection of gibs and tooling alignment. Follow the manufacturer's maintenance schedule for intervals and procedures.

The press accepts standard punch-and-die tooling appropriate for C-frame presses. It features an easy stroke adjustment mechanism to set press stroke and die clearance for different operations. For specific tooling dimensions and capacities consult the RAYMAX tooling guide.

Typical requirements include a level, reinforced foundation or floor capable of bearing the machine weight and reaction forces, appropriate electrical supply as per the machine specification, compressed air supply for pneumatic systems, and adequate clearance for maintenance and safety guarding. Contact RAYMAX or your distributor for the detailed site-prep checklist and electrical/pneumatic specifications.

RAYMAX and its authorized distributors generally offer operator and maintenance training, warranty packages, and options for customization (electromagnetic governor, tooling, control upgrades, etc.).
