JH21 Series High Precision Press

The JH21 Series High Precision Press, developed by RAYMAX, represents the latest advancements in plate processing technology. This versatile press is designed for cutting, punching, blanking, bending, and light stretching tasks.

Key Features

Robust Frame: Constructed with a C-Type steel-welded frame, this press offers high rigidity and minimal deformation. The compact design helps reduce vibration, enhancing the machine's longevity.
Precision Guiding: Features a hexahedral rectangle lengthened gib, ensuring high guiding precision and stable operation.
Efficient Gear System: Utilizes advanced, rigidly supported gears operating in an oil bath. This design minimizes noise, reduces shaft deflection, and extends gear life.
User-Friendly Operation: Engineered for high accuracy and efficiency, the press is easy to operate, providing excellent performance at a favorable price.

Clutch and Brake Control System

Pneumatic Clutch and Brake: The press uses a low inertia combined dry pneumatic friction clutch and brake from OMPI, Italy. This system ensures smooth performance, easy maintenance, and reliable safety.
Integrated Gear System: The driving gear is housed within the frame, submerged in an oil reservoir. Customers can opt for an electromagnetic governor for stepless speed regulation.
Safety Features: Equipped with a dual valve from TACO, Japan, and a pneumatic dual balance cylinder, this system balances the slide block and punch weight to minimize noise and impact.
Synchronous Detection: The press incorporates a cam controller paired with a proximity switch (Schneider) for reliable monitoring.

Electrical System and Safety Interlock

CE-Compliant Electrical Panel: The electrical panel features a cooling system and includes automation and electrical equipment from SIEMENS.
Safety Interlocks: Designed with protective fencing and safety interlocks, the press ensures safe operation. It includes a movable single-hand pedal switch for ease of use.
Control Mechanisms: The machine features both hands button and foot switch controls that meet OSHA standards. Additional safety features include front side covers with switches and backlight safety guards (Category-4).
Auto Grease Lubrication: An auto grease lubrication system, along with an easy stroke adjustment mechanism, significantly enhances the versatility of the press.

In conclusion, the JH21 Series High Precision Press is an excellent choice for industries requiring reliable and efficient pressing solutions.

1. What is the rated capacity of the JH21 C frame press?

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.

2. What types of operations can the JH21 Series perform?

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

3. What is the frame design and how does it affect performance?

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.

4. How is guiding precision achieved on this press?

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

5. What kind of clutch and brake does the press use?

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

6. Is there a hydraulic system in this machine?

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.

7. How does the integrated gear system extend gear life and reduce noise?

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.

8. What safety systems and certifications are included?

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.

9. What electrical and control components are used?

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.

10. Is stepless speed control available?

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

11. Does the press have automatic lubrication?

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

12. What maintenance is recommended?

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.

13. What tooling is compatible and how easy is stroke adjustment?

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.

14. What site requirements are needed for installation?

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.

15. Are training, warranty and customization options available?

RAYMAX and its authorized distributors generally offer operator and maintenance training, warranty packages, and options for customization (electromagnetic governor, tooling, control upgrades, etc.). For exact terms, warranty length and available options, contact RAYMAX sales or your local distributor.
