Typical service requirements are:

 

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. 

Operator Guards:

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

Electrical Systems:

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

Hydraulic Circuits

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
