Import Crankshaft Cbn Grinding Wheel — Buy in Bulk from Supplier in China

The Crankshaft CBN grinding wheel supplied by Zhengzhou More Superhard Company is designed for high‑speed, high‑precision grinding of crankshaft pins and journals. It is compatible with a range of CNC grinding machines including NAXOS (NOXOS‑UNION P310*1250 GF70), several TOYODA models (GCS63, GL5P‑63, GL6P‑100, GCH120B, GC32M‑63, GCH63B, GL63M‑T), JUNKER series (JUCAM5002/10, JUCAM500, JUCRANK5000, 6000) and SCHAUDT units (CF41, CF61, ZEUSMX, ZXII). The wheel is intended for processing steels such as 20Cr, GCr15, CF53, 45#, 55# and 80B high‑carbon grades. It is also listed for use on hydraulic tappet components and other automotive parts.

CBN provides exceptional hardness and thermal stability, allowing the wheel to maintain geometry under heavy material removal. The typical vitrified bond gives the wheel a long service life while delivering a consistent surface finish. Standard grit sizes for this class of wheel range from 30 to 80, giving a balance between material removal rate and finish quality. In the grinding industry a peripheral speed of 3000‑6000 m/min is common for CBN wheels of this diameter, and run‑out tolerance is usually held within ±0.1 mm.

Automotive manufacturers, engine rebuild shops and precision machining centres purchase this wheel to achieve tight dimensional tolerances on crankshaft components. The supplier offers the wheel on a wholesale basis but does not disclose minimum order quantities, unit price or lead‑time in the public listing; interested buyers should request a formal quotation. Shipping is normally arranged under FOB or CIF terms, with the wheels packed in wooden crates protected by film. Buyers are encouraged to confirm the exact machine model compatibility and request any relevant test certificates before placing an order.

Zhengzhou More Superhard Company is located at No.171 Zhongyuan Road, Zhengzhou, 450001, China. The firm is listed with a harbour‑level trust tier, indicating that third‑party verification has been completed, although the public response rate is shown as 0 % and no average response time is recorded.

The company markets a range of CBN and diamond tools for the automotive and engineering sectors, citing use by major manufacturers such as BMW, Ford and Toyota. The product page does not provide details on certifications, minimum order quantities, pricing or delivery schedules, so buyers should ask the supplier directly for any missing information.
