Recently, the 2014 National Machinery Industry's highest technology award - China Machinery Industry Science and Technology Award special award was announced, "Crankshaft flexible, precise, efficient grinding processing key technology and complete sets of equipment" won, which is also the first time China's machine tool industry won the award .
The project was undertaken by Beijing No. 2 Machine Tool Works Co., Ltd. (hereinafter referred to as “Beiji Machine Toolâ€), and has been supported by the National 863 Program and the National Science and Technology Major Project.
“The project team grinds a sword for 7 yearsâ€, Wang Bo, general manager of the second project of the project, introduced the precision and high-efficiency grinding requirements of the crankshaft. Through technological innovation, he successfully developed a complete set of equipment for crankshaft finishing and agile production line. From the crankshaft follow-up (cut point tracking) grinding related theory, method, process, functional components, complete machine manufacturing to the application of the complete technical system, the realization of the crankshaft non-circular grinding complete sets of equipment technology research and development and application of a major breakthrough It is the first in China.
In addition to breaking through key technologies, Beiji Machine Tool also carried out technical research work on digital design, machine tool structure analysis and optimization, processing status monitoring and information management technology of Tsinghua University and other related university enterprises, and finally made the grinding efficiency relative to The traditional eccentric clamp type crankshaft grinder is increased by 4 times.
The complete set of equipment can meet the crankshaft processing requirements of various types of internal combustion engines such as automobiles and ships, and provides powerful technical equipment support for promoting the development of technology and industry in China's internal combustion engines and other related fields. The series of technologies created by the project can also be extended to non-circular precision and high-efficiency grinding in the fields of automotive camshafts and robotic eccentric shafts. Based on this technology, Beiji Machine Tool has successfully developed CNC camshaft grinding machines, etc. The results have been successfully applied in automobiles, ships, diesel locomotives, military, industrial robots, air conditioner refrigerator compressors and other industries.
The successful development of crankshaft grinding equipment has made China the fourth country to master follow-up grinding technology and equipment after Britain, Germany and Japan.
Fiberglass Mesh is based on Glass Fiber woven fabric as substrate, the polymer emulsion coated with immersion resistance. So it has good alkali resistance, flexibility and latitude to highly tensile resistance,can be widely used for building internal and external wall thermal insulation,waterproof, anti crack.
It has Good chemical stability. Alkali resistance, acid resistance, water resistance, anti erosion,cement and other chemical corrosion; and resin strong adhesion, easy to dissolve in the styrene. High strength, high modulus, light weight.Good dimensional stability, stiff, smooth, not easy to shrinkage, good positioning capability.Good toughness. Anti impact performance is good.Mildew,pest control.Fire prevention, thermal insulation, sound insulation, insulation.
Application
(1) Fiberglass mesh for marble reinforcement
The fiberglass mesh for marble reinforcement is characterized by excellent fitting positioning, high strength, etc. Fiberglass mesh is woven by fiberglass yarns, which is coated by alkaline resistant latex.
This kind of product is usually used to do reinforcement for stone, mosaic, cement, wall materials, roofing, plaster, etc.
(2) Resin coated fiber glass mesh
Resin coated fiberglass mesh has the functions of waterproof, erosion resistance, long service life, etc.
The special resin coating on the fabric can minimize the distortion, and is compatible with various materials.
It is an ideal engineering material to be used in broad construction fields, such as marble & mosaic backing,road surface, water-proof and preventing cracks, etc.
(3) Fiberglass mesh for concrete
The fiberglass mesh is made of glass fiber. Special technique for weave is required to obtain this kind of
product. This kind of product has strong alkali erosion resistance and stability, long service life, etc., and
it is widely used in the field of decoration and construction.
(4) Fiberglass mesh for wall
Fiberglass mesh for walls is characterized by alkali resistance, stable dimension, good toughness, fire
protection, etc.
It is commonly used in the field of GRC wall panel, wall insulation, fire resistant board, reinforced cement
products, other decoration material, etc. Different sizes are available according to customers`
requirements.
(5) Fiberglass mesh for gypsum board
Fiberglass mesh for gypsum board is a very popular in the construction and decoration industries.
Many of its merits build and enhance its good fame, such as strong bonding with resin, thermal insulation,high modulus, light weight, excellent durability, etc. This kind of product can be used in the field of gypsum board and some related fields.(Fire board, interior and exterior walls, asphalt roofing, rubber products, etc.
