JPS Machinery boast the Largest Dealer Service Team in the UK and can cater for all new & used press brake machinery through our in house service team.
Typical Repair Breakdown Faults:
Operator guards not working
Rear fence interlocks mis aligned
condition of tooling & tooling clamping systems
Bend angle incorrect
Check infra red or Laser operator guards alignment
Press brake not going through its start up safety checks
Machine motor does not start
Check emergency stop buttons, check side & rear interlocks
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
Electrical faults such as sticking contactors
Typical Service Requirements:
At the beginning of the work shift, inspect the press brake, a visual inspection of all areas will allow you to notice and address small issues before they become significant problems
It is important to understand the function, design, and operation of your press brake
The operators role in service / maintenance of a 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 mean a less expensive fix.
it’s the small preventive measures that keep a Press Brake up and running.
A service / maintenance check list should include these five (5) key areas of a press brake:
Mechanical guards at side & rear of the press brake, check interlocks are working
Front Infra-Red or Laser Guards, check alignment of beams, tighten all brackets
Check emergency stop buttons, emergency button(s) dual circuits, the safety relay functions
Emergency stop buttons, check the dual circuits relays, check the safety relay, look for welding of contactors
Check all terminal strip connections , relays, terminal boxes on motors.
Reseat all printed circuit boards and check for physical damage (cracked solder points, burned parts, etc.).
Check all voltages coming from power supplies and transformers.
Check all external cables and switches fittings for damage
Check oil and control panel cooling fans are operational.
Clean control cabinet to remove dust particles
Clean Hydraulic oil is the key to a healthy hydraulic system
Keeping the oil clean and filling the reservoir to capacity are critical
Workshop dirt particles enter the hydraulic tank via the hydraulic tank breathers
Re-filter the oil every 6 months using a 10/15 micron filter
Completely replace the oil around 2/3000 hours of actual use
Clean the tank and replace the suction filters before replacing the hydraulic oil
Check all pipes & fittings for leaks
Check condition of tooling clamping systems, if mechanical are they effective
if Pneumatic check filters, empty water bowl – if Hydraulic check hydraulic oil tank
Check condition of all cables, clean screen, check system for conflicts
