Quick answer: The S-D508 from Southern Machinery is a moveable-blade V-cut PCB depanelizer for pre-scored boards. A round upper blade rolls along the V-groove while a flat lower blade backs the panel, so the board separates along the score line instead of being snapped over an edge. The platform accepts boards 0.2 to 5.0 mm thick, blade travel is 300 to 500 mm/s, and the machine runs on 230 V or 110 V at 40 W. It suits SMT and THT lines that want clean, low-stress separation of V-scored FR4, aluminium-backed and copper boards.
Why separate panels by machine instead of by hand?
A V-score is a controlled weakness, but the panel still has to be separated along it. Snapping it over a table edge works until it does not: the crack finds the weakest point, and that is often a solder fillet near the score line. Depaneling moves the failure to the place you designed for it.
- Stress goes into the score line, not the board. The rolling round blade and flat lower blade keep the board either side of the cut flat.
- A clean edge. The brochure describes the cut as made without fibre and without burr.
- Any panel width. The blade moves and the panel is supported; the brochure states no restriction on the width of the target PCB.
How does the S-D508 V-cut depanelizer work?
The panel stays on the platform and the cutting head travels. Following the operation manual:
- Support the panel with the V-groove over the flat lower blade (platform height adjustable 0 to 50 mm).
- Align the score line directly above the lower blade.
- Set the upper blade height with the knob (0 to 2 mm fine adjustment).
- Set the upper-to-lower blade gap to 0.1 to 0.2 mm, with both cutters in the same plane within 0.1 mm.
- Set the stop point to the panel length.
- Press the foot switch; the head returns to origin first, so each cut starts from the same place.
- The round blade rolls the groove while the lower blade supports the board.
- Unload; the display shows motor speed and a production total.

Which details should you confirm before ordering?
The product page shows both values where its source documents disagree, and so do we. Confirm these against the drawing for your configuration: the model code (S-D508, SC-D508 and ASC-508 all appear in documents), the machine dimensions, the blade steel grade, the speed controller scale, and the blade length versus the stop setting. The page also says the CE certificate covers the V-cut separator series including S-D508 and S-D509.
What should you check before choosing a depanelizer?
- Board material and thickness: 0.2 to 5.0 mm, built for V-cut FR4, aluminium-backed and copper boards.
- Score depth: remaining thickness across the V-slot of 0.25 to 2.0 mm.
- Component clearance: make sure no component collides with the blade body; a pre-machined blade is offered if a part sits close to the cut.
What to send for a quotation
Send your panel drawing with V-score position, board thickness and material, panel length, nearest component distance to the cut, and your supply voltage.
FAQ
Can the S-D508 cut boards that are not pre-scored?
No. It is built for pre-scored V-cut boards, not for routing or snapping.
What board thickness does it accept?
0.2 to 5.0 mm, with 0.25 to 2.0 mm remaining across the V-slot per the brochure.
What power does it need?
230 V or 110 V, 50/60 Hz, 40 W.
What is the warranty?
One year from the date of purchase, with lifetime maintenance, per the operation manual.
