PCB Cutting Machine — Precision Board Separation Solutions

UV Laser Cutting

Non-contact laser ablation for the lowest stress separation. UV wavelength (355nm) vaporizes PCB material with precision down to ±3μm, making it the preferred choice for flexible circuits, high-density interconnects, and boards with delicate components near cut lines.

• KL-5040 UV Laser Cutting System — ±3μm accuracy
• KL-5545 UV Laser Cutting System — Dual-galvo high-speed

Curve Routing Cutting

High-speed spindle routing along programmed paths for complex board contours. 4-axis CNC control enables cutting of irregular shapes, circular cutouts, and any-angle edges that straight-line methods cannot achieve.

• KL-3500II Curve Router — 60,000 RPM, dual worktables
• KL-3500WII Curve Router — Wide-format panels
• KL-3530 Curve Router — Mid-range precision
• KL-3530S Curve Router — Compact design

V-Cut & Guillotine Cutting

Straight-line separation for pre-scored or rectangular panels. V-cut machines split along pre-routed grooves, while guillotine cutters handle unscored boards with a clean blade action — both highly cost-effective for simple geometries.

• KL-5088 V-Cut Separator — Blade scoring for pre-routed panels
• KL-6208 Guillotine Cutter — Straight-line full separation

What is a PCB cutting machine?

A PCB cutting machine separates individual circuit boards from a production panel using precision cutting methods. Common types include UV laser cutting machines for zero-contact separation, curve routing machines for complex board shapes, and V-cut scoring machines for pre-scored panels. The goal is clean, low-stress separation that protects sensitive components.

What is the difference between laser cutting and routing for PCBs?

UV laser cutting is a non-contact process that uses a focused laser beam to vaporize material, producing zero mechanical stress — ideal for thin, flexible, and high-density PCBs. Curve routing uses a high-speed spindle (up to 60,000 RPM) to physically cut along a programmed path, suitable for thicker boards and complex contours. Laser cutting offers higher precision (±3μm vs ±0.05mm), while routing handles a wider range of board thicknesses.

How much does a PCB cutting machine cost?

PCB cutting machine prices vary significantly based on technology and automation level. Entry-level V-cut and guillotine machines start lower, while UV laser cutting systems represent a higher investment due to their precision capabilities. Inline automated systems with conveyor integration cost more than stand-alone units. Contact Keli Smart for a detailed quotation based on your specific requirements.

Can a PCB cutting machine handle flexible circuits (FPC)?

Yes. UV laser cutting machines (such as the KL-5040 and KL-5545) are specifically recommended for flexible PCBs because the non-contact process eliminates mechanical stress that could damage thin flexible substrates. Curve routing machines can also handle FPCs with appropriate fixturing, but laser cutting is the preferred method for maximum yield.
