AI-Powered supplier vetting

SummaryThe supplier is a combined company engaged in R&D, production, maintenance, and sales of CNC machinery, industrial automation equipment, intelligent robots, and related parts. It demonstrates established product and management credentials through CE marking for its machines, ISO 9001:2015 certification, OEM service for well-known brands, recent new-product development, and one stated national science and technology progress award. Production evidence includes three production lines, 21–30 quality-control staff, and stated output of 500 vertical machining centers. It offers one year of free spare parts and online/offline after-sales service, although customer-paid travel expenses apply. Service-management documentation is weak, with no written procedures for supplier assessment, corrective actions, or complaint handling. The supplier has no overseas warehouse, showroom, agent, or branch, but has attended EMO Hannover 2025. Financial credibility cannot be assessed from the provided year labels alone.

Supplier typeThe supplier is identified as a combined company whose scope covers R&D, production, maintenance, and sales of intelligent robots, CNC machinery, industrial automation equipment, CNC machine tools, control systems, and mechanical parts. Its product range includes machining centers, robodrills, gantry machines, CNC lathes, and turning-milling machines, indicating a machinery manufacturer and solution provider rather than a pure trading entity.

CertificationsThe supplier states that all machines have CE certification and holds an ISO 9001:2015 certificate. These are explicit certification credentials relevant to product conformity and quality-system management, although no additional certification scope or issuing-body details are provided.

R&D capabilityThe supplier reports new products during the past year, provides CNC solutions, and can customize special machine tools. It also reports one national science and technology progress award. Conversely, it has no available SDK and does not provide ODM services, so the evidence supports product development and engineering innovation but not broad software-platform or ODM capability.

Production capacityProduction evidence includes three production lines, 21–30 quality-control staff, stated annual output of 500 vertical machining centers, and a fastest production time of seven working days. Reported average lead time is within 15 working days in both peak and off-season, indicating defined production and delivery capacity, although the supplied output information is limited to one product category.

Customization capabilityThe supplier explicitly states that it can customize special machine tools according to customer needs and provides CNC solutions. It also offers OEM services for well-known brands, although it does not provide ODM services; the evidence therefore supports customer-specific manufacturing and OEM execution rather than ODM product-development services.

Product Q&A

Q:What specific costs can 'composite grinding' save for me?

It saves time cost by eliminating repeated setup time (efficiency up 40%), labor cost by reducing reliance on skilled technicians, and quality cost by lowering scrap and rework rates through single-setup accuracy.

Q:What materials can be processed by the machine tool?

It processes various high-hardness metals such as GCr15 bearing steel, quenched steel, alloy steel, cemented carbide, and ceramics. Select the appropriate grinding wheel and parameters based on material characteristics.

Q:Do you offer a trial grinding service? How does it work?

Yes, we offer free trial grinding. Provide workpiece drawings and sample blanks, and our engineers will conduct on-site or remote video tests, providing a detailed report to verify equipment effectiveness.

Q:What is the delivery time for the equipment?

Standard delivery is 45-60 days after deposit payment. For urgent needs or special configurations, contact our sales manager to coordinate schedule requirements.

Q:What are the key configurations of the LEYO 450L?

Key configs include Siemens 828D controller, 300mm max workpiece length, 200kg load capacity, 0-1000rpm spindle speed, Renishaw optical scale, 16-inch hydraulic chuck, and magnet filter.
