Chengyu Testing Machine is a high-tech enterprise integrating professional research and development, production and sales. The company took the lead in passing the "ISO9001 Quality Management System Certification" and was awarded the title of "National Authoritative Testing Standard Product" and "National Quality Service AAA Level Enterprise". 

The company has a software control system with independent property rights and a number of national patented products. The company gathers the industry's top material mechanics testing machine structure design experts, professional tribological testing technology program research and design experts, specially-appointed engineers and laboratory testing equipment analysis experts to provide lasting impetus for the company's development. 

The MVFW-1A friction and wear testing machine produced by the company is a

friction form of rolling, sliding or sliding-rolling compound motion under a certain contact pressure. It has a stepless speed regulation system and can be used at very low or high speeds Evaluate the friction and wear properties of lubricants, metals, plastics, coatings, rubber, ceramics and other materials, such as low-speed pin discs (with large discs and small discs, single needle and three needles) friction function, four-ball long-term wear resistance and four-ball rolling Contact fatigue, ball-bronze three-piece lubrication performance, as well as thrust washer, ball-disk, mud wear, rubber seal lip seal torque and stick-slip friction performance test, matching reciprocating module can achieve reciprocating friction and wear motion. The testing

machine has a wide range of applications in various professional technical fields of tribology, petrochemicals, machinery, energy, metallurgy, aerospace, universities, research institutes (institutes) and other departments. The advantages of the company's friction and wear equipment are analyzed as


1. Loading method: This type of testing machine is the first time that our

company has introduced servo motor loading in the industry. It has strong

controllability and low failure rate. After years of continuous improvement, its

performance is stable and reliable. Among them, double floating bearing technology and gapless guidance technology And the buffer cross-balance technology is the guarantee of the accuracy and stability of the test force, reduces the system error, and ensures the accuracy of the test force and friction force real-time tracking measurement;

2. Main body structure: During the friction test, the impact of the vibration of

the motor and accessory parts on the wear marks should be minimized. Therefore, we adopt the overall main body, thicken the support plate, and use the Taiwan TECO servo motor to drive the main shaft. The related transmission components are also Use imported precision bearings;

3. Electrical part: The equipment adopts an independent embedded industrial

controller, an industrial metal touch screen, and an independent analysis module, which can effectively ensure the impact of the equipment on the performance of the control part when the equipment is high-speed or the oil film is ruptured and violently vibrated;

4. Control software: Software can generally achieve real-time acquisition, but we

are dedicated software independently developed (software for the transformation of universal universal material testing machines), and professional test programs can be established according to different standards. 5. Service team: We not only produce the equipment (for companies with no

R&D strength to assemble at will according to drawings), but also have an

independent technical service department (more than 100 research and

development friction and wear testing machines cooperated with colleges and

universities for many years), which can be real-time for specific problems We analyze and solve them. At the same time, the Hengxu Testing Machine-Research and Exhibition Center, which we invested and constructed in the national new material industrial park, has been put into operation, providing a stable base for the company's later R&D and expansion (lease of workshops, unlicensed production enterprises with potential safety hazards, quality and Service can't keep up).
