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 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. 

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.

Optional spring damping foundation pads under the mild steel bed plate ensures low vibration during press operation.

Screw, thrust bearing and guides are continuously lubricated by re-circulating oil
lubrication system.

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 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.

• 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.

• Prakash Presses with robust ring frame construction gives highest rigidity minimizing deflection of the frame to almost zero thereby giving incredible tools life & part quality. Oil dip gears provided to enhance press life & low sound level. No open parts for the highest safety of operator.

Slow Draw Speed: 

• Three times slow drawing speed compared to ordinary mechanical draw press for highest drawn part quality with virtually no draw lines & still the same production.

Auto gauge variation control system draws blank even with thickness variation minimizing rejections. Motorised blank holders reduce die setting time unbelievably just at the touch of a single button without any manual settings by operator.

Quick Auto Ejection System:
This system facilitates operator to remove drawn Components earlier for highest safety.

• Improves metal flow times by keeping material in the work portion by nearly 300% longer period.
• Slower velocity in the tool improves part finish.
• Faster production speeds without increased forming speed thanks to faster slide return rate.
• Lower impact, shock, noise and vibration improves die, press and other equipment life.

• Automatic Lubrication System
• Pneumatic Clutch
• Electrical Control Panel
