AI-Powered supplier vetting

SummaryThe supplier is a privately owned, standalone combined manufacturer and seller of machinery, hardware, molds, mechanical parts, CNC machine tools, industrial robots, and related equipment. It has 30 employees, two production lines, four qualified service-capability suppliers, valid manufacturing contracts with associated subcontractors, and a valid import/export license. Its customization capability is supported by sample-based, design-based, and full-custom services, 3D software design, and professional technical expertise. However, it reports no supplier-management-system certification, no private mold capability, no new products during the past year, no overseas agents or branches, no overseas warehouse or showroom, no in-stock capability, and no stated customer cases or major-brand OEM experience.

Supplier typeThe supplier is a privately owned, standalone company classified as a combined business, with stated activities covering manufacturing and sales of machinery, hardware, molds, mechanical parts, CNC machine tools, industrial robots, and automation-related equipment. It also holds a valid import/export license, supporting its ability to conduct international trade.

CertificationsThe supplier reports no certification for supplier management systems. This is explicit evidence that the requested certification status is absent.

After-Sales capabilityThe supplier has no overseas warehouse, showroom, agent, or branch, and reports zero countries where overseas services are offered. Although it has participated in an offline trade show and is located near Shanghai Port, the provided information does not establish operational after-sales support coverage.

Production capacityProduction capability is supported by two production lines, a broad range of machining and grinding equipment, documented and uniformly followed finished-product inspection instructions, valid contracts with associated subcontractors, and one-month average peak- and off-season lead times. Limitations include no in-stock capability and a relatively small workforce of 30 employees, but the stated manufacturing infrastructure provides explicit evidence of operating capability.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, and full customization. It also provides 3D software design services and operates equipment including CNC machining centers and multiple specialized grinding and turning machines, supporting its stated technical customization services.

Product Q&A

Q:What is the main advantage of precision ground ball screws over rolled ones for CNC machines?

Precision ground ball screws offer superior accuracy and minimal backlash compared to rolled types. The grinding process ensures tighter tolerances, making them ideal for high-precision CNC machining where repeatability and surface finish are critical.

Q:How does the 97 percent transmission efficiency impact CNC machine performance?

The 97 percent transmission efficiency significantly reduces servo motor load and energy consumption. Combined with a temperature rise of less than 3 degrees Celsius, it ensures thermal stability during high-speed heavy loads, preventing precision drift and maintaining consistent machining accuracy.

Q:What maintenance is required to ensure the long service life of these ball screws?

Regular lubrication with grease or oil every one to three months is essential. Additionally, keep the screw clean with protective covers to prevent contamination, and check axial clearance annually. Proper maintenance can extend service life to over 8000 hours.
