Crankshaft Grinding Wheel

Our Crankshaft Grinding Wheel is specially engineered for high-performance grinding applications, delivering superior precision, high efficiency, and extended tool life. Designed to meet the rigorous demands of crankshaft and camshaft production, this grinding wheel is widely used in automotive, aerospace and heavy-duty engine component manufacturing.

It is ideal for grinding main journals, crankpins, cam lobes, flange necks, thrust faces, and end faces with consistent accuracy. The wheel offers excellent thermal stability, uniform wear resistance, and outstanding surface finish, even under high-speed, continuous grinding conditions.

Superhard CBN Tools Machining Bearing

Advantages of Halnn Tools Machining Bearings

1) Excellent both abrasion resistance and impact resistance;

2) High cutting efficiency and long tool life;

3) Patented product, non-metal adhesive CBN inserts.

Wind power bearings are difficult to machining after heat-treated. with the development of the modern Inserts industry, CBN Inserts is accepted by more and more customers. The last processing step of processing of wind power bearing processing uses BN-H200 Grade, which not only improves the processing efficiency but also reduces the processing cost.

When machining the outer ring of a wind turbine bearing, intermittent cuts are formed due to oil holes in the moon groove of the outer ring raceway, and the machining allowance at the moon groove is higher than the machining allowance of the raceway and the inner hole flange Therefore, the machining performance of the CBN Inserts is more important.

For wind power bearings, the accuracy tolerance of the raceway radian is 0.08, and the surface roughness of the raceway is Ra0.4
