Typical Metal Guillotine Repair Breakdown Faults:
Rear entry guards out of alignment
Chipped or worn guillotine blades
Front finger guard damaged
The back gauge measuring system needs re calibrating
Material hold downs leaking
Machine motor does not start emergency stop buttons, 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
Electrical faults such as sticking contactors
Typical Metal Guillotine Service Requirements:
At the beginning of the work shift, inspect the metal cutting guillotine 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 metal cutting guillotine
The operators role in service / maintenance of a Metal Cutting Guillotine 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.
A service / maintenance check list should include these key areas of a Metal cutting guillotine
Keeping the metal cutting guillotine productive can be accomplished by performing these simple planned maintenance tasks. When a guillotine / shear is serviced properly, replacement costs and catastrophic failure are avoided.
Understand The Guillotines Capacity:
The main cause of metal cutting guillotine failure is overloading it beyond the OEM’s started capacity
Metal cutting guillotines are designed to cut metal of a known thickness, width, mechanical properties
When these capacity limits are exceeded, damage occurs, so ensure all potential users of the metal cutting guillotine fully understand its capabilities.
Front finger guard set at correct height, the height set so as not to allow a finger to pass under it
Check rear entry guarding, interlocked gate or photocell barriers, check they are operational
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 the cutting beam return cylinders are functioning, some guillotines use gas springs, are they ncorrectly pressurised
Guillotine blade Condition
Is the cutting edge sharp, is the cutting edge chipped ? any such problems, then turn guillotine blade to a new sharp chip free edge
Setting the guillotine blade gap correctly is key to extending blade and machine life. Setting the proper clearances for blade cutting affects the required drive power, hydraulic down action cylinders cut quality
Check metal cutting guillotine is level, free of any frame twist & securely bolted down to the floor
