Growing-up Ningbo Anjiesen

Ningbo Anjiesen has pursued the idea of “Market-oriented, Taking Science and Technology as Driving Power ” since its establishment, having attracted some famous bearing manufacturers to come to our company for negotiations and cooperation. For many times, there have been discussions over the theory of grinding and honing with experts from TIMKEN, INA/FAG and so on. As the design and make of machine tools is a systematic engineering that needs cooperation among people from different industries, different cultures and different countries, Ningbo Anjiesen has strengthened the faithful cooperation with all parts suppliers, and therefore, have come to a strategic partnership agreement with some world-famous machine tools accessory makers such as German SIEMENS, Japan FANUC and Mitsubishi, French SCHNEIDER, Italy MARPOSS, etc. so as to have laid a solid foundation for parts production up to the world standards.

Improved Processing Medium
Ningbo Anjiesen has been improving its processing equipment and process in order to keep the quality of machine tools. Our company is equipped with lathe machines, milling machines, coordinate boring machine, high-precision universal grinder, internal grinder, surface grinder, etc. to ensure the manufacturing precision of parts. The pilot drill for CNC machines is used to ensure the uniformity of parts and changeability of spare parts. CNC cutting machines, bending machines, punching machines and nibbling machines are used to make machine cover and electric cabinet, with plastic spraying to ensure its appearance clean and beauty. Advanced inductive linear tester with high precision and height instruments available are used in the production process to ensure the stable manufacturing quality of whole machine.

Ningbo Anjiesen has been closely following the development trends of the international machine tools circle and the advanced technology and keeping up with the advanced level of equipment, technology, processing and inspection devices.

Scientific Quality Management
In the organization of the company, GM directly controls the QC department, which shows the serious attitude that Ningbo Anjiesen has taken towards product quality with high requirements.
The company has established a complete quality assurance system from product design assessment to production planning, to determination of processing lines, and from outsourced parts to machine delivery, each cycle of which is in supervision state. The company has been certified under ISO9001 from British Standards Institution, CE? and machine export quality permit. The QC department is consisted of measuring room, process check team and outsourced parts check group, with digitalized measuring means.

R&D system
During the establishment of the company, we had lots of input into software and hardware in terms of technical R&D. Thus we have trained a team of people with high efficient and high quality to develop products. Besides, we have also established a technical development center with improved functions and advanced level in China, and after some planning the company has formed the whole process of development from investigation of clients, product planning, structural design, analogue math to product trial production, and the match of theory with actual data.

Technical R&D system
Ningbo Anjiesen’s development ability has greatly improved after a series of practice over the products.

• The stable condition of dynamic circle-forming under the centerless grinding

and the study and results of mathematic mould of dynamic dimension accuracy are used, which are quite useful in that it guides the on-line control in? machine making and actual operation.

• According to the forming line requirements for races of taper and cylindrical

roller bearings, and based on the test results of tiredness life and the log curve formula, we have developed a log dresser with high performance to price, which is an invention with patent.

Full series of grinding and honing machine products

In terms of the two major categories of ball and roller bearings, Ningbo Anjiesen has made the following machines: Auto production lines and individual machines for grinding and honing large, medium and small ball bearings, and large, medium and small taper(cylinderical) roller bearings, individual machines for two-row spherical roller bearings, thrust spherical roller bearings, auto production lines and individual machines for grinding and honing automobile hub bearings, etc.

Constant-speed grinding, with clamping electric current at 0.1~2.0A adjustable, with High-low switchover.

Work rpm and wheel rpm are settable on touch screen. The dressing for race grinding machine is handled by 2-axis motion, which can arrive at 32-provision backlash and interpolation dressing by single-point diamond. It is possible to provide straight, hyperbolic and log, with crowning amount of 0－40mm adjustable. Honing race by way of small oscillation and big reciprocation mechanism whose feeding is driven by servo motor. Two honing methods like small oscillation and large reciprocation and small oscillation. The original ground crowning form can be maintained. Honing formula for 5-provision, stone pressure, oscillation frequency and work rpm can be settable on touch screen. With stone loss alarm equipment by pressure. Oscillation mechanism is of sleeve-type with mist lubrication, its structure simple and long in life. The electric cabinet is of fully-sealed structure of IP54 protective grade, with air-con for constant temperature and? with network function for communication.
