Typical Press Brake Faults:

  • Press brake not going through its start-up safety checks
  • Press Brake does not start its initialization sequence
  • Press Brake does not start a bend sequence
  • Operator Infra-Red guarding not working
  • Operator Laser guarding not working
  • Emergency stop buttons not functioning/damaged
  • Rear or side fence interlocks misaligned, not functioning
  • Bend angle incorrect, recalibration of knife tooling crowning
  • Condition of Press Brake tooling & tooling clamping systems
  • Leaking hydraulic cylinders, requiring the seals replacing
  • Low hydraulic pressure is often caused by the low viscosity
    of old hydraulic oil
  • High Hydraulic oil temperature, should not exceed 150 degrees Fahrenheit
  • Hydraulic filters in need of cleaning or changing, replace the air-cooled heat exchanger filter
  • Slow pressure build-up,i.e more than 2 seconds – check relief valve is working
  • Faulty Hydraulic pump motor, the motor nipple has not been used as recommended by the motor manufacturer
  • Oil leaks – Tighten or replace leaking hoses or fitting
  • Electrical faults such as sticking contractors, faulty solenoids
  • Check foot pedal cable, rewire foot pedal cable, replace the foot pedal

Press Brake CNC Controller Issues

  • JPS Machinery Ltd have recognized the importance of a thorough knowledge of a variety of multi-axis CNC controllers
  • CYBELEC, DELEM, ESA, ELGA etc, both older units and the latest CNC Controls, plus knowledge of the CNC control for AMADA, TRUMPF, LVD, DURMAZLAR

CYBELEC CNC controls:

DNC 60 – DNC 80 – DNC 800 – DNC 90 – DNC 900 – DNC 1200
Cybtouch 8PS – Cybtouch 12 PS – ModEva Pac – Modeva 19T

DELEM CNC controls:
DELEM DA-53T -DA-58T – DA-66T – DA 69T

ESA CNC controls:
Esa S 630 – S 650 – S 650 W – S 660 W

If requested we can also assist in refresher operator training for the above CNC Press Brake controls:

Ongoing Press Brake Maintenance

Inspect the Press Brake at the beginning of each work shift:

  • Check Guarding, Laser, Infrared , Mechanical interlocked,  systems are functioning correctly
  • Make a visual inspection of the Press brake, address small issues before they become significant problems
  • It is important to understand the function, design and operation of your Hydraulic Press Brake
  • The operators role in service, maintenance of a Hydraulic Press Brake is a major part of keeping the equipment running efficiently.
  • It is important to immediately investigate strange noises, vibrations, or something that doesn’t look right.
    The quicker problems are detected and corrected, can often means a less expensive fix.
  • It’s the small preventive maintenance measures that keep a CNC Hydraulic Press Brake up and running.

A maintenance schedule should include the following:

  • Clean Hydraulic oil is the key to a healthy hydraulic system.
    Dirt particles may enter a aspirated hydraulic tank.
    Keeping the oil clean and filling the reservoir to capacity are critical, re filter the oil every 6 months, using a 10/15 micron filter, Completely replace the oil around 2000/3000 hours of actual use
  • Clean the tank and replace the suction filters before replacing the hydraulic oil
  • Leaking hydraulic cylinders requiring the seals replacing
  • Low hydraulic pressure often caused by high oil temperature, or old oil low viscosity
  • Hydraulic filters in need of cleaning or changing
  • Faulty Hydraulic pump motor the motor nipple has not been used as recommended by the motor manufacturer
  • Check the hydraulic ram’s, the Press Brake hydraulic piston rods should be moist, but not dripping oil
  • Check for oil leaks on all hydraulic lines
  • Check for loose bolts around the Y1 & Y2 cylinders.
  • Check the mechanical connections of the Y1 & Y2 cylindersto the top beam
  • Check the oil temperature
  • Check condition of all tooling & intermediary clamping

Check Operator Guarding:
To do this,  break the operator guarding whilst the top beam is descending down, do not put your hands into the Press Brake, use a  length of steel – the Brake Press should stop immediately

If there are any failures with the Operator guarding or emergency stop button(s) do not operate the Press Brake, but do immediately inform management or refer to the owner’s manual for guidance.

Electrical Systems:

  • Emergency stop button(s), check the dual circuit [does your Press brake have a dual safety circuit ??] – look for arcing and welding of contactors – check the safety relay [does your Press brake have a dual safety circuit ??]
  • Check cables on foot pedal, replace
  • Check all terminal strip connections, relays, terminal
    boxes on motors
  • Check all printed circuit boards, look for physical damage (cracked solder joints, burned parts, etc.)
  • Check all voltages coming from power supplies and transformers
  • Check all external cables and switches fittings for damage
  • Check control panel cooling fans are operational
  • Clean control cabinet to remove dust particles
