54.3mm Diameter B126 Electroplated CBN Grinding Disc For Precision Grinding

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.
