Frequently Asked Questions (FAQ)

  1. What is the purpose of ram counterbalance (balancer) pistons?

They minimize mechanical play, extend the life of press components, reduce load on the motor, and shorten braking distances.

  1. How is the upper die weight (attached to the ram) determined?

It is set during the design phase based on the dies to be used. For different die weights, the air pressure in the balancer pistons must be adjusted accordingly.

  1. What is the function of the hydraulic overload safety system?

In theory, a press can apply infinite force at bottom dead center. To protect the press and die from overload, a hydraulic safety system is installed.

  1. Can the pressing force on the die be measured in real time?

Yes, with digital load monitoring systems. These allow real-time measurement of the force needed by the die. Ales Press offers this feature as an option.

  1. Do these systems require calibration over time?

Yes. The hydraulic overload safety and digital load monitoring systems need calibration based on usage. This can be done by Ales Press service teams during maintenance if requested.

  1. How often should press maintenance be performed?

It depends on usage type and frequency. Maintenance is recommended at least once a year. Maintenance points and intervals are defined based on press type and working conditions.

  1. What safety category do presses fall into?

Link Motion presses are generally designed to meet Category 3 or 4 safety levels per EN ISO 13849-1 and EN 692 standards. They use dual-channel systems, monitored safety relays, and emergency stop systems to ensure safe operation.

  1. Are there parts that need periodic replacement?

Yes. Depending on usage, components like brake/clutch linings, lubrication filters, and motor belts may require replacement.

  1. Is a cushion system used in presses?

Yes, depending on part geometry. A lower cushion can be added to help with forming or part ejection. It can be hydraulic or pneumatic depending on capacity.

  1. Are the presses compatible with Industry 4.0?

Yes. All Ales Press products have infrastructure that supports Industry 4.0. Software and hardware can be adapted to customer needs.

  1. What types of oil are used in eccentric presses?

Different oils are used in different parts. At Ales Press, all lubrication is done in a closed loop system with oil. Typical oils include:

  • Slide Guide oil
  • Gear oil
  • Hydraulic oil
  • Conditioning oil
  1. What is a press safety valve?

In air-clutch presses, movement occurs with compressed air. The dual-coil safety valve controls the air supply to the clutch for safe operation. According to EN 692, dual-coil valves are mandatory on all CE-certified machines.

  1. What is a hydraulic overload protector?

It’s a safety system that detects overload in an eccentric press. It releases hydraulic pressure to push the ram upward, preventing damage to the press.

  1. What is slide adjustment (reglaj) in presses?

It allows connecting dies of various heights to the press. A motorized mechanism between the connecting rods and the ram moves the slide up/down independently from crank rotation—used only during die setup.

  1. What is the nominal tonnage (working distance) in eccentric presses?

It is the distance before bottom dead center where the press starts applying force. This is the effective working range where the rated tonnage is delivered.
