Our History
Founded in 1995, the company has evolved from its initial focus on the bearing industry (under Ningbo Jinshi), to the CNC machine tool optical machine sector (under Ningbo Jinkai), and further to the complete CNC machine tool industry (under Ningbo Mino). Drawing on advanced machine tool technologies from Taiwan, Japan, and Germany, and integrating them with the characteristics of domestic enterprises, it has independently developed a range of CNC machines, including vertical machining centers, gantry machining centers, CNC lathes, drilling and tapping centers, and special-purpose machines. Its featured models include horizontal machining centers, 5-axis machining centers, vertical lathes, and specialized machine tools for relevant industries. The company boasts comprehensive capabilities covering independent R&D, mechanical processing, optical machine assembly, sheet metal manufacturing, complete machine assembly, and automated supporting solutions.
Company Profile
The company adheres strictly to a modern ERP management system across all operations, from machine tool design, production and processing, to assembly technology and quality control. It boasts a comprehensive range of modern production equipment, supported by advanced matching testing and R&D equipment - all ensuring the precise accuracy and stable quality of every machine tool manufactured.
Manufacturing & Testing Capabilities
The company possesses robust manufacturing and testing capabilities, backed by key equipment including:
• Taiwanese precision guideway grinders
• High-precision CNC coordinate boring machines
• Precision horizontal machining centers
• High-precision gantry machining centers from Taiwan's Zhongmao
This equipment provides reliable manufacturing support for processing components such as machine housings, guideways, and bed frames. Its metrology and testing center is equipped with dual-frequency laser interferometers from Renishaw (UK), coordinate measuring machines (CMMs) from Hexagon (USA), and Mitsubishi system test machines. These tools deliver dependable guarantees for critical testing needs in product manufacturing and technological development. Currently, the company's manufacturing capacity and testing methods rank among the leading standards in China's domestic industry.
Production Model & Processing
The company's products primarily focus on cast iron, iron, and steel components. For cast parts, the company sources externally and then processes them in-house into machine tool components for assembly. For some steel parts and high-volume small components, it adopts a collaborative external production model to enhance material inventory efficiency.
To meet the requirements for high-precision workpieces, the company's processing workflow follows a strict sequence: conventional machine tools for initial processing, followed by high-precision machines for finish machining - ensuring compliance with high-precision standards. It has shifted from traditional processing methods to CNC-based production, reducing the need for workpiece fixtures and processing time while aligning with high-precision manufacturing and green environmental protection requirements.
Core Process Flows
• Machining Process: Cast iron/steel raw materials → Rough machining → Finish machining → Grinding → Inspection & Warehousing. The company's processing equipment primarily consists of machining centers, lathes, and precision grinders.
• Assembly Process: Component inspection → Processing & inspection of mating workpieces → Assembly → Precision adjustment → Mechanical running-in → Laser inspection → Cyclic inspection → Test machining of workpieces → Warehousing.
Technological & Talent Advantages
CNC machine tools are high-precision products with stringent technical requirements. The company has established a robust manufacturing technology system by integrating:
• Production and design expertise from Taiwan
• Advanced manufacturing technologies from overseas
• Collaboration with renowned domestic universities and institutions
This system provides solid support for project implementation. Additionally, the company places great emphasis on comprehensive competence when recruiting employees, laying a foundation for enhancing and safeguarding its overall strength and quality.

★ Warranty and Maintenance Services
The equipment enters the warranty period after formal acceptance at the buyer's site. The warranty period is one year for mechanical components and one year for the CNC system.
During the warranty period, the seller provides free repair services for any equipment malfunctions; however, damage to parts caused by human error is not covered by the free warranty.
If equipment malfunctions occur during the warranty period, the seller will provide a phone response and diagnostic support within 4 hours of receiving the buyer's phone call or written notice. If on-site repair is required, the seller will send technicians to resolve the issue within 48 hours (this does not apply if special parts need to be replaced and require a long lead time for delivery).
Unnatural damage caused by improper use or unauthorized modification by the buyer is not covered by the warranty, and the buyer shall bear all repair costs.
For equipment malfunctions occurring after the warranty period, if spare parts replacement is needed, the seller will quote the cost of spare parts plus labor fees. Repairs and part replacements will be carried out only after the buyer's approval.
