SummaryWuxi Changyi Machine Tool Manufacturing Co., Ltd. is a machine-tool manufacturer offering cylindrical-hole, conical-bore, step-hole, surface-end, external, and centerless grinding equipment. It provides extensive customization and ODM services, reports new products within the past year, and has OEM experience with well-known brands. Production facilities include turning, drilling, milling, grinding, laser cutting, and spraying equipment, with stated annual productivity of 1,000 sets for internal and external grinding machines. Quality systems include five inspectors, traceability for raw materials, written inspection instructions, complaint procedures, and corrective-action procedures. The supplier has exported for 19 years, but overseas service infrastructure is limited: no overseas warehouse, showroom, agents, or branches are reported. Financial credibility cannot be assessed because the provided financial entries only identify years, not financial results. A notable operational weakness is the absence...

Supplier typeThe supplier is identified as a machine-tool manufacturer. Its products serve single-unit, small-batch, and large-batch production and include semi-automatic and fully automatic machine tools for multiple grinding applications.

CertificationsThe supplier is reported to hold one national science and technology progress award. No specific certification, standard, or certification validity information is provided, so broader certification status cannot be established.

After-Sales capabilityThe supplier has a clear, followed procedure for handling customer complaints. However, it reports no overseas warehouse, showroom, overseas agent, or branch, limiting documented overseas service infrastructure.

R&D capabilityThe supplier reports new products within the past year, provides ODM services, and holds one national science and technology progress award. It does not have an available SDK, but the available evidence still explicitly supports product-development capability.

Production capacityManufacturing resources include lathe, drilling, milling, grinding, laser-cutting, and spraying facilities, with stated annual productivity of 1,000 sets for internal and external grinding machines. The supplier has one production line and does not continuously reconcile quantities for every batch or production run, indicating a production-control limitation despite substantial equipment and product scope.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. It also provides ODM services, directly supporting broad customization capability.

Client casesThe supplier reports OEM service for well-known brands, participation in CIMT 2023, 19 years of export experience, and exports accounting for 21%–30% of total sales. These records demonstrate market and export experience, although no named customer cases are provided.
