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:How does the double nut design eliminate backlash in CNC machining?

The double nut preload structure applies axial compression to remove internal clearance between the nut and ball screw shaft. This forces the balls into constant contact with the raceway, achieving zero backlash and ensuring sub-micron repeatability during direction changes and aggressive cutting operations.

Q:What maintenance is required to sustain the 97 percent transmission efficiency?

Regular lubrication with grease or oil every one to three months is essential to minimize friction and wear. Additionally, protective covers should be used to prevent contamination from dust and debris, and axial clearance should be checked annually to maintain thermal stability and precision under high-speed heavy loads.

Q:How does this ball screw shaft integrate with linear guide systems for CNC machines?

The precision ground ball screw shafts are engineered for seamless compatibility with linear guide systems, providing enhanced motion accuracy and load distribution. This integration ensures stable, low-friction linear movement, preventing deflection and vibration to achieve flawless surface finishes in CNC machine tool applications.
