Answers to the questions we are asked most often, and what to do when a machine stops.

FAQ

Frequentlyasked.

What panel thickness can your machines score?
Automatic and CNC models handle 0.6-3.2 mm on the 480 platform and 0.4-3.2 mm across the CNC and SH-380-E ranges. Send us your stack-up and we will confirm blade geometry.
Can you score aluminium-backed LED panels?
Yes. Aluminium-based PCB is a primary application across the range, which is why tungsten carbide is our standard blade material. PCD cutters are available for abrasive substrates.
Sideway positioning or PIN positioning?
Sideway positioning references the panel edge: fast, no tooling plate, best for repeated panel families. PIN positioning references tooling holes, so groove position is absolute regardless of edge quality. Choose PIN when groove position is a drawing tolerance.
Do you build custom machines?
Yes. Blade count, conveyor length, turning configuration and panel size can all be adapted. Custom builds are quoted individually with a drawing for approval before production.
What is the delivery time?
Standard models ship within the lead time confirmed on your quotation. Common blade sizes are stocked so consumables do not hold up production.
What warranty do you offer?
Machines carry a 12-month warranty on main components. Wear parts including blades, belts and seals are excluded, as is damage from incorrect air supply or voltage.
Do you provide installation and training?
Remote commissioning and operator training are included. On-site service is available in China and through regional partners elsewhere; travel terms are quoted with the machine.
Which voltage do the machines use?
Standard build is AC 380 V three-phase, 50/60 Hz. Other voltages can be specified at order, so tell us your plant supply before we quote.
Troubleshooting

Before you call —check these four.

Four things cause most V-CUT problems. Checking them takes five minutes and saves a service visit.

Troubleshooting

Burrs or a ragged groove

Usually a worn blade or the wrong angle for the substrate. Check blade wear marks and confirm the cutter angle against the drawing. For aluminium, verify the blade is carbide or PCD, not a steel body.

Troubleshooting

Groove position drifts

On sideway machines, check the edge guide for chips or wear. On PIN machines, check pin condition and that the tooling plate is seated. A 0.05 mm drift is nearly always mechanical, not software.

Troubleshooting

Board surface scratched

Vacuum cups worn, or dust extraction below 40 m³/min letting chips recirculate. Check the filter and confirm the extraction flow at the port.

Troubleshooting

Machine trips or faults on start

Air pressure below 5.5 kg/cm², or phase/voltage mismatch. The controller shows a fault code; note it and send it to us with a photo of the cabinet display.

When you contact us, have the model, the fault code if any, and a short video of the machine running. It cuts diagnosis time in half.

Still stuck?

Send the model, the fault code and a video. We will diagnose remotely and, if a part is needed, confirm stock and price.
