Servo Screw Press

About Servo Screw Press

The frame of PARKASH Screw Press consist of four steel casted frames, held together by four
hydraulicaly pretensioned tie rods, and thus ensuring longevity of the frame, and forming of more accurate parts, and reducing the overall weight and size of the press.

Screw is made of high-alloy forged, quenched and tempered
steel which provides longer screw life. The screw bearing in the
machine frame is a heavy-duty spherical flanged bearing.

Screw Nut

Screw nut is of special wear resistance bronze alloy fixed in the ram.
Thread geometry in the screw drive with optimized tooth profile and four
start threads, has already proved to be durable and tough in the past.

Motors and Driving System of the Press

The drive comes from two heavy-duty high torque motors linked via a bull gear to the external diameter of the flywheel. The press force is limited by a slipping clutch provided in the flywheel.

Safety

PARKASH Servo Screw Press is equipped with digital
tonnage monitor in which the force exerted in forming process is measured and recorded by strain gauges. When the maximum permissible force is exceeded, the
system displays a warning message and cycle stops, to prevent possible damage to the press. Photoelectric sensors mounted on both columns front and back.

Ram and Guiding System

Ram is of high-quality cast steel and is guided in four guides at
45 degree with continuous lubrication, so that it is able to
maintain constant clearance in spite of heat expansion. Bronze
and steel are used as guide pairs.

Advantages over hydraulic double actions:

• Increased production capacity due to superior reliability and improved performance.
• Large working capacity/safeguarding by means of overload protection.
• Exact adjustment and maximum repeat accuracy of the energy output.
• Wide range of stroke control options.
• Optimized, exact ram guidance.
• Optimum controllability of the forging process
• Reduced energy consumption and noise emission.
• Long lifetime and operational safety due to robust design.
• The spring stiffness of the frame is precisely adjusted by pre-tensioned tie rods.
• High press stroke rate even at low forming energies.
• Low maintenance and service costs

Advanced PLC-Based Automation

Enhance your manufacturing precision with the integrated PLC-based control system, enabling fully automated and reliable operations. The intuitive touch screen interface streamlines programming and real-time monitoring, making machine adjustments effortless and minimizing the scope for errors during critical metal forming tasks.


Superior Precision and Safety

Achieve exceptional repeatability of 0.01 mm, assuring high-quality output in forging and assembly applications. The Servo Screw Press is equipped with crucial safety measures, including emergency stop and overload protection. The automatic centralized lubrication system further promotes smooth operation and machine longevity.


Versatile Industrial Application

Designed for flexibility, the Servo Screw Press caters to diverse industrial requirements such as forging, metal forming, and assembly. Available in different sizes, it easily adapts to varying production demands and factory layouts, supporting both small-scale and large-scale manufacturing environments across India.
