HEAVY INDUSTRY AND MACHINING
Zero Flex, High-Strength Body
The 60 ton eccentric press machines, which are the exact bridge point of the transition from light industry to heavy industry in industrial manufacturing, constitute the most critical workforce of production lines. These machines, which work in a wide spectrum from white goods spare parts to heavy steel construction fasteners, from thick sheet bending of the automotive sub-industry to construction molds, are considered the "backbone" of workshops.
With our machining and mechanical engineering experience carried from 1988 to the present as Karmaksan Machine, we analyze all the physical difficulties encountered in high-tonnage productions. Every press manufacturing that comes off our production line is not just a machine where metal hits metal, but a smart engineering system that protects the life of your mold and ensures the safety of your operator.
Unshakeable Power in Heavy Conditions: The Steel Body Advantage
When a pressing force of 60 tons is applied, the shock waves and kinetic energy the machine is exposed to reach enormous proportions. Old-style and low-cost cast iron machines develop micro-cracks and flex in their bodies over time due to these shock waves. Even a 1-millimeter flex at the moment of impact causes your mold to press incorrectly and your expensive cutting blades to blunt.
One of the most important features that makes the Karmaksan brand a leader in the sector is that we produce our presses with a monolithic steel body press architecture having a thickness far above standards. These C-type chassis, which are joined by special welding methods and whose stress is relieved in heat treatment furnaces, offer a "zero flex" guarantee even when the machine is running at full capacity. An inflexible machine returns to you as burr-free products and up to 30% extra mold life.
Pneumatic Clutch and the Peak in Occupational Safety
As the tonnage increases, the severity of accidents that may occur in a possible operator error also increases. For this reason, in accordance with the occupational safety laws set by Turkey and Europe (CE), we have completely abandoned traditional mechanical (rigid) systems in all our 60-ton models. Instead, we integrate the much faster and safer pneumatic press (air-clutched clutch and brake) systems.
The working logic of the pneumatic system offers flawless safety. While the press ram is moving downwards, if the operator takes their hand off the dual-hand safety button even for a moment or if an object enters the light barrier, the double-coil safety valves inside the machine instantly cut off the airflow. The multi-ton system is locked in place in milliseconds. Moreover, thanks to this system, the machine exhibits an extremely vibration-free and quiet performance in continuous and single stroke modes.
Technical Superiorities of Our 60-Ton Models
- Precise and Wide Stroke Adjustment: A 100 mm precise ram adjustment mechanism designed to adapt to drawing, spinning, and cutting dies of different depths.
- High Revolution Capacity: Agile performance capable of 60 strokes per minute despite its 60-ton power, thanks to a powerful 7.5 HP motor and a specially balanced giant flywheel disk.
- Expanded Plate (Table) Size: With its wide T-slotted table measuring 540 x 800 mm, it's easy to mount the massive progressive dies of the automotive and white goods sectors.
- Semi-Automatic Central Lubrication: Equipment that lubricates the crank, connecting rod, and heavy bearings, which are the main heart of the system, on a time-adjusted basis without leaving it to operator initiative, preventing bearing seizures.

Frequently Asked Questions (FAQ) About the 60-Ton Eccentric Press
1. Why should I choose the Karmaksan brand over cheap 60-ton presses on the market?
Karmaksan machines are not made of cheap cast iron, but entirely of ST-52 quality high-strength steel plates. Because of this, our machine never flexes or cracks under high impact, extending the life of your mold by up to 30% and saving you from hidden costs.
2. What is the long-term contribution of the steel body to my business?
Cast bodies fatigue over the years and create deviations in the ram axis, causing defective products. Our steel construction body, whose stress is relieved in special heat treatment furnaces, works with the zero-tolerance of the first day even after 20 years, keeping your production quality flawless.
3. How fast is your after-sales technical service and fault response?
The stoppage of your production is as unacceptable to us as it is to you. With the advantage of being a 100% domestic manufacturer, in case of a mechanical or pneumatic malfunction, our expert team intervenes on-site on the same day in Istanbul and its surroundings, and within 24 hours at the latest in other cities.
4. What is the material quality of the components (crank, bearing, gear) you use in your machines?
Our crankshafts that meet the 60-ton pressure are manufactured and ground from Turkey's best forged steel alloys (4140 quality). For bearings, we absolutely do not use roller bearings, but instead use specially cast phosphor bronze materials that are extra resistant to heat and wear, reducing the risk of failure to zero.
5. If a part breaks on the machine, how long will it take to find the spare part?
Karmaksan is not an assembly company, but a 100% direct manufacturer. All parts belonging to our machine, from connecting rods to eccentric gears and pneumatic valves, are constantly in stock at our factory and shipped the same day you order.
6. What kind of safety does the pneumatic clutch system provide me compared to a mechanical clutch?
Mechanical clutches can only stop after completing their rotation in an emergency, causing accidents. Our pneumatic system, on the other hand, cuts off the airflow in a fraction of a second and nails the 60-ton ram in mid-air. This system completely prevents occupational accidents and is the basic requirement of European CE norms.
7. What does the warranty period and scope of Karmaksan 60-ton presses include?
The mechanical body, crankshaft, and gear groups of all brand-new 60-ton presses you buy from our company are under a full 2-year (24 months) Karmaksan warranty against manufacturing and material defects. We also have a commitment to provide spare parts for 10 years.
8. Are installation, commissioning, and training charged when the machine arrives at my factory?
No. After the machine is unloaded at your factory, our expert engineers perform the installation free of charge. In addition, we provide your operators with practical, free training on safe use, PLC screen menus, mold clamping, and periodic lubrication.
9. How many parts can I produce per hour/minute with a 60-ton press?
The machine's own speed is 60 strokes per minute (SPM) as standard. If you integrate your machine with an automatic roll sheet feeder (servo) system, you can reach a continuous production capacity of 3,600 products per hour without the operator having to wait.
10. Is your electrical and PLC automation system compatible with my factory's grid?
Yes. Thanks to the A-quality world-brand switchgear materials such as Siemens, Schneider, or equivalent that we use in our panels, and our highly protected inverter (speed control) devices, your machine will never be affected by voltage fluctuations in your factory.
11. If I buy a 60-ton press, how easily can I assemble and disassemble my molds?
Thanks to our motorized ram (stroke) adjustment system, your operators do not have to struggle with heavy wrenches. By moving the ram up or down with millimeter precision using the directional buttons on the control panel, they adjust the mold height in seconds without getting tired.
12. Is there a risk of the machine guides burning or seizing when running at high speed?
There is no such risk. Because the 'Central Semi-Automatic Lubrication Unit' in our machines pumps oil in pressurized doses to all slides, bearings, and connecting rod joints while the machine is running, providing excellent lubricity without the operator having to remember.
13. Can I use this 60-ton press on hard steels in the automotive sub-industry?
Absolutely. Thanks to our rigid (non-flexing) table with wide T-slots and our high-torque flywheel, you can cut and form all kinds of hard materials, from DKP sheets to stainless and thick steels, without burrs and without stalling the machine (stopping the motor).
14. Is the use of a light curtain (safety barrier) mandatory on the machine, and is it included in the price?
According to occupational health and safety laws, the use of light curtains and dual-hand control buttons is mandatory. Because we as Karmaksan cannot risk human life, we offer these top-level safety equipments included in the price as standard.
15. What should I do if I have an old, faulty mechanical press that cannot pass occupational safety?
Don't scrap your old press! In our 'Press Revision Center' at our factory, we take your idle machine, machine its body and bearings, equip it with zero pneumatic systems and smart panels, and deliver it back to you in brand-new condition for 40% of the cost of a new press.
16. What is your delivery time when I order a new 60-ton press?
Since our machines are standardized on our mass production line, our general delivery time is extremely short, averaging 20 to 30 working days from order confirmation. We can stretch our production planning for you in your urgent projects.
17. Do you offer leasing, bank loans, or installment options for payments?
Yes. In order to ease the investment cost of our industrialists, we provide full support to our customers regarding investment incentive leasing through our contracted banks, commercial loans with favorable rates, and flexible payment plans to be determined by mutual agreement.
18. Does the machine make a lot of noise and vibrate the factory floor while working?
Our heavy-duty extra-thick steel chassis absorbs the impact internally and transmits minimum vibration to the floor. Furthermore, thanks to the vibration damping (vibro-pad) feet we offer as an option, our machine can work silently even on upper floors.
19. Can I set up an automatic production line with the 60-ton press in the future?
Yes, the electrical diagram and PLC brain of our machine are designed to be completely open to external automation (Industry 4.0). When you buy a coil unwinder, straightener, or servo driver in the future, you can communicate with our machine over a single cable in seconds and switch to fully automatic production.
20. I want to see your machine up close and bring my mold to test it, is this possible?
Of course! Our doors are open to all our industrialists. You can visit our factory in Istanbul, see our manufacturing processes (welding, heat treatment, grinding) with your own eyes, and personally test the power of our machine by bringing your own sheet metal/mold and doing a die tryout.
