PCD Guide Bar Reamer
A leading China manufacturer and supplier, Wangdefu's PCD guide bar reamer combines an ultra-hard polycrystalline diamond cutting edge with a precision diamond guide bar, achieving IT5-IT6 tolerances and a mirror-like surface finish of Ra0.1-0.4μm. Specifically designed for machining large-diameter, long overhanging holes in non-ferrous metals and composite materials, it offers consistent accuracy, burr-free surfaces, and high throughput efficiency.
At Wangdefu, we understand the challenges of machining large, deep holes with high accuracy. Our Quality PCD Guide Bar Reamers are engineered to provide:
High straightness and roundness for L/D ratios up to 20
Mirror-finish hole walls without secondary polishing
Consistent performance for repetitive high-volume production
These reamers are ideal for materials like high-silicon aluminum, magnesium, carbon fiber composites, graphite, ceramics, and sapphire.
