54.3mm B126 Electroplated CBN Grinding Disc for Precision Grinding

Our electroplated CBN grinding disc is engineered for precision grinding of high hardness steels. A monolayer of cubic boron nitride (CBN) abrasive is precisely electroplated onto a high-speed steel body, producing a sharp, free-cutting surface with excellent form retention. With a 54.3mm outer diameter, 25.2mm bore, 1mm body and 8mm CBN layer, it is built for applications where dimensional accuracy and surface finish matter most.

Why It Delivers Precision

• Tight dimensional tolerance — controlled outer diameter, bore and layer width ensure accurate mounting and stable grinding.
• Monolayer electroplated bond — a single layer of sharp CBN crystals with high grain protrusion removes material with low grinding force and minimal heat.
• Uniform abrasive distribution — even crystal spacing keeps cutting performance consistent from the first pass to the last.
• Superior form retention — the hard CBN layer holds its profile, protecting precision geometry during long production runs.
• Controlled surface finish — stable cutting behavior supports fine, repeatable surface quality.

Differentiated Advantages

• CBN versus conventional abrasive — far higher hardness and thermal stability than aluminum oxide, delivering longer life and less frequent dressing.
• Consistent batch quality — repeatable manufacturing keeps grinding results stable across production lots.
• Custom built on request — outer diameter, bore, layer width and grit size (B126 and other grades) can be tailored to your drawing.
• Cost efficiency — the durable layer reduces downtime and abrasive consumption for high-volume precision work.

Typical Precision Applications

• Precision grinding and re-sharpening of hardened steel and high-speed steel cutting tools.
• CNC tool grinding, profile and slot grinding with tight tolerances.
• Mold and die finishing, bearing steel and alloy steel precision grinding.
• Fine finishing where surface quality and geometry must be closely controlled.
