Winway is a professional manufacturer and supplier of PCD PCB V-CUT Cutter, also known as PCD V-Score Cutter, designed for precision PCB V-groove processing. This specialized tool adopts an alloy-steel substrate with a PCD polycrystalline diamond V-shaped cutting edge brazed onto the outer periphery and is used in matched pairs of two cutters. It cuts V-shaped grooves between connected PCB panels while maintaining a reserved residual thickness for easy subsequent depaneling. Featuring outstanding wear resistance, it performs well on high-glass-fiber and high-TG PCBs. It delivers stable V-angle and residual-thickness accuracy with minimal burrs. Its service life is much longer than that of ordinary tungsten-steel V-CUT cutters, making it suitable for large-batch continuous PCB V-cut production.

China PCD PCB Small Corner Radius Cutter Manufacturer – Winway provides precision PCB machining tools featuring a high-temperature brazed PCD diamond cutting edge and an alloy steel substrate. Designed for micro-R-angle forming, hole-edge passivation and edge deburring of printed circuit boards, this cutter offers high wear resistance, consistent machining performance and low chip adhesion. It is compatible with FR-4, high-glass-fiber boards, aluminum base boards and composite boards.

For wholesale and customized PCD Shank Corner Radius Cutter orders, Winway provides a PCB machining tool designed for precise edge rounding and consistent production results. This forming tool is specially developed for the printed circuit board industry, combining a PCD cutting edge with a high-strength alloy steel shank substrate through a high-temperature welding process. It is mainly used for R-arc chamfering and sharp edge trimming after PCB contour machining. The tool features superior wear resistance, smooth cutting, reduced edge chipping and fewer burrs. It is compatible with conventional boards such as FR4 and CEM series, as well as high-glass-fiber and high-filled difficult-to-machine boards. It supports stable mass production and helps improve PCB edge appearance yield while extending tool service life.

Winway offers the PCD PCB Straight Corner Radius Cutter for wholesale and customized orders. Designed for precision PCB machining, this tool adopts a composite structure with a polycrystalline diamond (PCD) cutting edge and an alloy steel shank. It is applied for profile milling and edge radius machining of PCB, composite materials, acrylic and other plates. The tool features ultra-high hardness and an extremely low friction coefficient. It produces a superior surface finish on workpieces, helping reduce burrs and edge chipping. Its wear resistance and service life are much longer than those of ordinary carbide tools. Suitable for high-volume automated CNC finishing, it maintains stable radius dimensions and enables smooth R forming on workpiece edges.

Winway PCD PCB Combination Corner Radius Cutter is a complete set of combined PCD tools for PCB corner rounding machines. One set has two specifications: 4 pieces per group or 5 pieces per group. The cutter body adopts an alloy steel substrate with embedded PCD straight-tooth blades with straight cutting edges. Relying on the step combination structure of the whole set of cutters, it can complete PCB board edge cutting and corner radius forming in one pass. Common outer diameters are φ150 mm and φ160 mm; tooth specifications are 10 teeth and 16 teeth. PCD teeth feature high wear resistance and long service life when machining fiberglass circuit boards, making the cutter suitable for mass PCB board edge cutting and grinding processing.

Dongguan Weicheng Electronic Co., Ltd is a professional manufacturer & supplier of PCD PCB Edge Milling Cutter in China. This PCD edge trimming saw blade is a special post process trimming tool for PCB full automatic inline depanel lines. Featuring PCD polycrystalline diamond brazed teeth with pre set R corner / chamfer profile, it is not designed to cut through panels. It is specially used for grinding, deburring and corner rounding of pre cut PCB side edges to eliminate edge flash and copper foil lifting. Custom R radius, angle, outer diameter and inner hole are available for large volume automatic PCB production.
