Import Bearing Ring Turning Machine — Buy in Bulk from Supplier in China

The bearing ring turning machine from Zhejiang Toman Precision Machinery Co., Ltd. is a CNC-controlled lathe designed specifically for machining raw or semi-finished steel rings into precision bearing components. The machine employs computer numerical control to achieve precise dimensional accuracy and surface finish on ring outer diameters, inner diameters, and groove profiles. Based in Xinchang, Zhejiang Province, the supplier targets manufacturers serving automotive, aerospace, and general precision engineering sectors.

Typical CNC turning machines for bearing rings utilise hardened and ground box-way or linear guide construction to damp vibration during interrupted cuts on high-carbon chromium steel. The control system generally supports G-code programming with canned cycles for facing, rough turning, finish turning, and groove cutting. Standard spindle through-hole capacity, maximum swing over bed, and chuck size vary by model tier, with typical bearing ring diameters ranging from 20 mm to 500 mm depending on machine specification. Buyers should confirm whether the offered model uses a turret or gang-tool configuration, as this affects tool change speed and complexity of groove geometry achievable.

The intended buyer is a bearing manufacturer or automotive tier supplier seeking to bring ring machining in-house rather than subcontract to grinding houses. Zhejiang Toman states the machine has programmable settings and user-friendly controls, though the degree of automation (bar feeder, gantry loader, or manual loading) is not specified. Payment options mentioned include L/C and T/T, with flexible MOQ, though exact figures require direct negotiation. No price, delivery time, or specific model designation is provided in the source data.

Zhejiang Toman Precision Machinery Co., Ltd. is located at No 29, Xinshi Road, Xinchang, Shaoxing, 312500, Zhejiang Province, China. The company holds an imported supplier tier designation on the platform, with a harbor trust tier and no recorded response rate or average response time. Xinchang is a known cluster for precision machinery and bearing equipment manufacturing in eastern China, suggesting the supplier operates within an established supply chain ecosystem for machine tools and related equipment.

The supplier does not disclose year of establishment, factory size, number of employees, annual revenue, or installed machine base. No ISO certification numbers, patent portfolio, or reference customer list is provided in the source profile. Buyers should independently verify manufacturing capability, request video factory verification, and confirm whether Zhejiang Toman designs and builds the machines in-house or acts as an assembler or distributor for another OEM. The supplier's mention of ISO certification in the source description lacks a specific certificate number or scope, which should be validated directly.
