About SHANGHAI ZHUYUN MACHINERY CO.,LTD - Metal Working Machinery Supplier in China

China‑based Shanghai Zhuyun Machinery Co.,Ltd operates a catalogue of five distinct products. The list includes a honing machine (HS 8460.13) built with a cast‑iron body, hardened steel spindle and diamond or CBN stones; K, BL, L, Y series honing mandrels (HS 8466.93) of precision tool steel with brass or bronze wear parts; a honing head (HS 8466.29) made from hardened tool steel with carbide inserts; honing stones (HS 6804.22) composed of aluminum‑oxide or silicon‑carbide abrasives; and single‑pass diamond honing tools (HS 8202.40) featuring a steel body and diamond abrasive segments. Each entry specifies the material construction and the relevant HS‑code family, allowing buyers to match customs classifications directly to the product line.

The supplier’s top‑category tags span steel tools, jewellery‑making machines, ceramic machines, metal‑working machinery, tattoo and leather machinery, as well as onyx gemstones and extrusion machines. While the catalogue currently focuses on precision honing equipment, the broader category list indicates capability across multiple high‑tech manufacturing sectors, all sourced from facilities in Shanghai, China.

Product Range and Specialties of SHANGHAI ZHUYUN MACHINERY CO.,LTD

The honing machine series (e.g., MRL1800, MRL1805, MVR220, MVRL160) typically deliver spindle speeds up to 5 000 rpm, positioning accuracy within ±0.001 mm and surface‑finish capability of Ra 0.1 µm. In the industry, such machines are offered with CNC control, coolant‑through spindles and interchangeable diamond or CBN stones graded by grit size from 30 µm to 1 µm. Honing mandrels in the K, BL, L, Y series are forged from high‑carbon tool steel (often S7 or H13) and feature replaceable brass or bronze wear inserts to maintain concentricity during long‑run production. Honing heads equipped with carbide inserts are standard for high‑hardness workpieces, providing wear resistance up to 1 800 HV. Honing stones classified under HS 6804.22 are supplied in Al₂O₃ grades ranging from 120 to 2 400 grit, while SiC variants target higher removal rates on non‑ferrous alloys. Single‑pass diamond honing tools combine a hardened steel shank with segmented diamond abrasives, typically graded by diamond concentration (0.5 % - 2 %) and bond type for finish control.

Industry practice for these categories includes ISO 9001 quality management, CE marking for EU markets, and, where applicable, UL certification for North America. Buyers often request test reports confirming grit distribution, diamond bond strength, and dimensional tolerances (e.g., mandrel concentricity < 0.02 mm).

Trade and Export Information - SHANGHAI ZHUYUN MACHINERY CO.,LTD

China ranks among the world’s top exporters of machine tools and abrasive products, with major import destinations in the United States, Germany, Japan and South‑East Asian manufacturing hubs. The HS 8460.13 family (machine tools for working of metal) and HS 6804.22 (abrasive products) are routinely inspected under China’s General Administration of Customs for correct tariff classification and export licensing for high‑technology items. Typical certifications demanded by overseas buyers include ISO 9001, CE Declaration of Conformity, and, for abrasive stones, MSDS compliance with REACH regulations. Shipments are normally packed in wooden crates or bulk pallets, sized for 20‑ft or 40‑ft containers, and quoted on FOB Shanghai or CIF destination terms. Export documentation frequently includes a commercial invoice, packing list, certificate of origin and, where required, an inspection certificate from a recognized third‑party agency (e.g., SGS or Bureau Veritas).

Sourcing from SHANGHAI ZHUYUN MACHINERY CO.,LTD - Buyer Guidance

When sourcing honing equipment from this supplier, request a detailed datasheet that lists spindle speed range, positional accuracy, recommended abrasive grades and recommended coolant flow. Ask for ISO 9001 certification and, for abrasive stones, an independent particle‑size analysis report to verify grit distribution. Verify that the HS code on the commercial invoice matches the product description and that packaging specifications (e.g., crate dimensions, moisture barrier for stones) meet your logistics requirements before confirming order.

For larger orders, buyers should obtain a sample of the honing stone or diamond tool to assess surface‑finish capability on a test workpiece. Confirm that the supplier can provide a CE or UL conformity statement if you are supplying to EU or North‑American markets, and ensure that the packaging includes protective cushioning to prevent chipping of diamond segments during sea freight.

What types of honing machines does SHANGHAI ZHUYUN MACHINERY CO.,LTD offer?

The catalogue lists honing machines such as the MRL1800, MRL1805, MVR220 and MVRL160, all classified under HS 8460.13. They feature cast‑iron bodies, hardened steel spindles and interchangeable diamond or CBN stones.

Which HS codes apply to the supplier’s honing mandrels?

Honing mandrels (K, BL, L, Y series) are recorded under HS 8466.93. They are made from precision tool steel with brass or bronze wear components.

What materials are used for the honing stones?

Honing stones are classified under HS 6804.22 and are produced from aluminum‑oxide (Al₂O₃) or silicon‑carbide (SiC) abrasives, supplied in various grit grades.

Are certifications like ISO 9001 or CE available from the supplier?

The facts do not list specific certifications, so buyers should request ISO 9001 quality‑management certification and, for EU shipments, a CE Declaration of Conformity.

What is a typical minimum order quantity (MOQ) for single‑pass diamond honing tools?

While the catalogue does not state an MOQ, industry practice for HS 8202.40 diamond tools often starts at a batch of 100‑200 pieces, depending on the required diamond concentration.

What lead time can a buyer expect for a complete honing machine set?

Lead times for machine tools from Chinese manufacturers usually range from 6 to 12 weeks after order confirmation, depending on configuration and stock availability.

How are the products packaged for export?

Machinery and large components are typically crated in wooden boxes, while abrasive stones are packed in sealed, moisture‑proof bags and placed on pallets for 20‑ft or 40‑ft container loading.

Which regions most frequently import these types of honing equipment?

Key importing regions include North America, the European Union, Japan and Southeast Asia, where automotive, aerospace and precision‑engineering sectors require high‑accuracy honing solutions.
