There are some processes in industrial production where standard press machines cannot handle the load. Processes such as shipbuilding parts, defense industry steel armors, heavy construction equipment chassis elements, or industrial tube/tank manufacturing require a massive striking power. At this point, 125-ton eccentric press machines, which are the biggest investment item of metal processing facilities and single-handedly shoulder the production capacity of the factory, come into play.

With our machining and mechanical engineering experience gained since 1988 as Karmaksan Machine, we are building not just a press, but a giant "production base" for our industrialists. Designed for thick sheet cutting and deep forming operations where ordinary machines are helpless, our 125-ton giants are designed to solve the toughest jobs in your factory like pulling a hair out of butter.

The Source of Power: Geared Transmission System

To obtain a pressing power of 125 tons, it is not enough to just use a large motor or a massive flywheel. Standard direct drive (transferring power directly from the flywheel to the crankshaft) systems are insufficient at these tonnages and cause the motor to stall. As Karmaksan, we use geared transmission press (reducer system) technology to obtain this massive power without vibration.

So what does this system bring to your workshop? The high-speed, low-torque power taken from the motor is reduced in speed by passing through special alloy and helical-angle steel gear groups (reducer), but the torque (striking power) is multiplied to incredible dimensions. Thanks to this eccentric press with reducer architecture, the machine does not experience the slightest strain during the 125-ton strike. There is no loss of revolution the moment the ram touches the mold, and a perfect, burr-free surface is obtained in cutting quality.

Unforgiving Body: Steel Construction Architecture

At moments when such high kinetic energy is released, the machine body absorbs the biggest shock. Cast iron or bodies with insufficient wall thickness will crack under 125 tons over time and shift the press ram off its axis. This shift means that your molds worth millions of liras will be shattered in a single blow. In order to eliminate this risk 100%, we build our machines far above the standards, using heavy steel plates under heavy-duty steel body press norms.

Our body is produced as "C-Frame" or "H-Frame" with robotic welding technology, completely relieved of thermal stress. This "zero flex" guaranteed body is specially designed to meet the standards of a defense industry press operating with very low tolerances. The male and female parts of your mold overlap in perfect parallelism with every stroke.

Critical Safety: Hydraulic Overload Fuse

Mechanical jamming in a 125-ton giant can leave irreparable damage. If a double sheet is pushed between the mold due to an operator error, the machine can break its own connecting rod or crankshaft with its own power. In Karmaksan 125-ton models, the "life-saving" equipment that prevents this disaster, the hydraulic fused press technology, is present.

This hydraulic cushion integrated into the connecting rod is pressure-sensitive. In the millisecond when the power applied by the machine exceeds 125 tons, the hydraulic fuse blows (discharges the oil) and resets the pressure. The machine idles, no breakage occurs, and your mold is saved. The system is refilled with oil with just a single button, and production continues from where it left off within 3 minutes.

Industrial Equipment of Our 125-Ton Giants

• Pneumatic (Air) Clutch: A double-valve clutch/brake system operating in perfect synchronization with the gear group, providing emergency stopping in milliseconds at CE occupational safety standards.
• Motorized and Digital Stroke Adjustment: A system that adjusts the heavy and massive ram mass via a motor through the PLC screen without the need for the operator to turn it manually.
• Ram Balancing Pistons: Technology that pneumatically suspends the massive ram weight and upper mold group weight, relieving the load on the gears and tripling the life of the machine.
• Full Automation Infrastructure: PLC equipment that prepares your factory for dark production (unmanned production) by working fully integrated with coil unwinder, straightener, and servo driver systems.

Heavy Press Revision and Facility Modernization

Investing in a 125-ton machine is a big decision. However, if you have old heavy presses with mechanical clutches or defective presses sitting idle in your factory, selling these massive iron piles for scrap is a serious waste for your business. Karmaksan Machine brings these machines back to life as a leading press revision center in Turkey.

We remove the old mechanical systems, add brand new pneumatic clutch and hydraulic overload protection systems, and re-turn the crank bearings with zero precision. We transform your old workbench into a modern heavy industry metal forming center that complies with the new occupational safety laws.
