Chipping on the panel edges

Hits OEE: Quality

Symptoms: The bottom or top face of the cut shows chipped edges.

Scoring blade not aligned with the main blade

Align the scoring blade to the main blade kerf.

Scoring blade height or width wrong

Set the scoring blade so its kerf matches the main blade.

Blades dull

Change the blades on a fixed schedule.

Blade projection wrong for the panel

Set the blade height for the stack thickness.

Prevention: Test cut checked for chipping after every blade change.

Cuts not square

Hits OEE: Quality

Symptoms: Parts are out of square or the cut wanders.

Pusher or fence not square to the saw line

Check and adjust the squareness with a test panel.

Panels moving under the pressure beam

Check the pressure beam force.

Grippers slipping

Replace worn gripper pads.

Saw carriage guides worn

Check the carriage guides.

Prevention: Squareness test cut each week.

Parts out of size

Hits OEE: Quality

Symptoms: Dimensions are off by a constant amount or vary.

Pusher not calibrated

Calibrate the pusher against a measured cut.

Encoder or drive fault

Check the axis position.

Kerf setting wrong in the program

Check the blade thickness in the optimiser.

Panels not against the stops

Check the alignment devices.

Prevention: Size check on first parts of each pattern.

Burn marks or blade overheating

Hits OEE: Quality

Symptoms: Cut faces show burn marks and the blade runs hot.

Blade dull

Change the blade.

Feed too slow for the material

Increase the carriage speed.

Wrong tooth shape for the board

Use the blade designed for the panel type.

Resin build-up on the blade

Clean the blade.

Prevention: Blade hours or metres tracked.

Pressure beam not holding the stack

Hits OEE: Quality

Symptoms: Panels move during the cut.

Air or hydraulic pressure low

Check the supply to the pressure beam.

Beam seals worn

Replace the seals.

Beam not lowering fully

Check for obstructions and the beam guides.

Stack too high

Keep the stack within the machine rating.

Prevention: Pressure beam force checked monthly.

Blade vibration or wobble

Hits OEE: Quality

Symptoms: Cuts are rough and the saw is noisy.

Dirt between blade and flanges

Clean the flanges at every blade change.

Blade damaged or out of tension

Replace the blade.

Arbor bearings worn

Check and replace the bearings.

Blade nut not tight

Tighten to the maker torque.

Prevention: Flanges cleaned at each blade change.

Poor dust extraction

Hits OEE: Quality

Symptoms: Dust gathers on panels and in the saw line.

Extraction hood blocked

Clear the hood and ducts.

Air flow too low

Check the extraction system.

Hood not following the blade

Check the hood mechanism.

Blast gate closed

Open the gate for the saw.

Prevention: Extraction checked weekly.

Saw carriage faults

Hits OEE: Availability

Symptoms: The carriage stops, moves slowly, or alarms.

Carriage guides dirty or worn

Clean and lubricate the guides.

Drive belt or rack worn

Inspect the drive and replace worn parts.

Limit switch fault

Check the switches.

Motor or drive overload

Check the drive current and free any binding.

Prevention: Carriage guides cleaned weekly.

Wrong labels or parts mixed up

Hits OEE: Quality

Symptoms: Labels do not match the parts, or stacks of different parts get mixed.

Cutting pattern changed after labels were printed

Print labels from the pattern being cut.

Optimiser data not matching the saw

Check the link between the optimiser and the saw.

Label printer settings wrong

Check the label template and printer.

Parts stacked without a clear order

Use the stacking order the pattern prints.

Prevention: Spot checks of label against part at each pattern.

Scoring blade wearing quickly

Hits OEE: Availability

Symptoms: The scoring blade needs changing far more often than the main blade.

Scoring depth too deep

Set the scoring blade to cut just through the surface layer.

Scoring blade not suited to the board

Use the scoring blade made for the laminate.

Blade speed or rotation wrong

Check the scoring motor and direction.

Abrasive coatings

Use blades with tips suited to abrasive boards.

Prevention: Scoring blade life tracked separately from the main blade.

Stop the same fault coming back

Recurring panel saw stops usually trace to a cause you cannot see by hand. The partner we recommend is Fabrico: it tracks OEE and downtime live from PLCs, IoT sensors or AI cameras; where cameras are fitted, the video of a stop sits next to its machine data so the cause can be reviewed; and a technician opens the work order from the stop in the same system. Data is hosted in the AWS EU region, and Fabrico and the company behind it hold ISO/IEC 27001, ISO/IEC 20000-1 and ISO 9001.
