CBN Superabrasive Grinding Wheel

Basic Info

Made with synthetic Cubic Boron Nitride (CBN) superabrasive, second only to diamond in hardness. Designed specifically for efficient, precise, low-temperature grinding of high-hardness (HRC 45+) ferrous metals like hardened steel, HSS, and tool steel. Enables extremely long wheel life and stable machining accuracy.

Customer reviews

Elena Rodríguez · Toolroom Manager

We purchased your white aluminum oxide precision wheels for our HSS tool sharpening. The results are outstanding, achieving excellent edge finish and straightness that fully meets precision tool requirements. More importantly, your technical team provided highly professional selection advice, recommending the most suitable grit and hardness combination based on our equipment and material, avoiding common burning issues. Professional products coupled with professional service.

Lucas Miller · Production Supervisor

Your grinding wheels deliver stable hardness—we use brown alumina models for carbon steel grinding, no workpiece burn or vibration issues. The wear resistance is better than our previous supplier, cutting our replacement frequency by 20%. Worth the investment.

Sophie Laurent · Senior Mold Technician

We perform polishing on high-end molds long-term, with stringent surface quality requirements. Your company's polyurethane elastic polishing wheel series was a pleasant surprise. Their hardness grading is very accurate, allowing for a smooth and efficient transition from rough to mirror polishing. The abrasive distribution is even, preventing uneven streaks on the mold surface, and the wheels themselves wear slowly with a long service life. This has become the standard configuration for our polishing process.

Product Description

Product Features:

Exceptional thermal stability (withstands >1400°C), maintaining strength and cutting ability at grinding temperatures, greatly reducing workpiece thermal damage (burn, cracks). Extremely low wear rate and superb wheel form retention, ideal for batch, high-precision production on CNC grinders.

Product Specifications:

Typically consists of a steel or aluminum hub with an outer CBN abrasive layer. Bonds include electroplated (single layer), vitrified, or metal (multi-layer). Key parameter "concentration" indicates CBN content (100% concentration = 4.4 carats/cm³). Grit sizes from #120 to micron level. Requires rigid machine tools and ample coolant.

Product Applications:

Precision grinding of automotive camshafts, crankshafts, gears; machining of high-temperature alloys in aerospace; sharpening and slot grinding of high-hardness complex tools (e.g., carbide end mills); superfinishing of precision bearing (P4/P2 class) raceways.
