Nisshin Tool Company
Japan's Nissin tool is a small-diameter cutting tool manufacturer, founded in 1954, so far, half a century, founder of the current president's father, Yong Goto. Plant at the beginning, the main commission undertake processing of high-speed steel tools, the main products are drill bits, reamers, side cutters and so on. 1972 launch of the company's own products Power End Mills (HSS), 1980 production of Die Carbide End Mills industry needs. ?
In 1991, Japan's bubble economy burst, the Japanese company's operations into the tool encountered unprecedented difficulties. They closed many office, industrial park in the center of Sendai in northern established a new production plant, originally owned by four small factories scattered along the cage to make production more concentrated. Product categories, highlighted the production of carbide end mills. After drastic restructuring, after two years out of trouble. Currently, the company employs 125 people, the production of standard end mills are about 100 species, sizes of about 5,000. Now the mention of small-diameter carbide end mills, people will immediately think of Japanese companies into the tool. The company's small-diameter cutting tool products, manufacture of precision molds and small parts manufacturer in, enjoy a high reputation. ?
Sendai, Japan into the tools the company has two factory buildings, production buildings and develop the building. The production building covers an area of 12,000 square meters, building area of about 2,500 square meters; development building covers an area of 5000 square meters, building area of about 1,000 square meters. Tools of the production lines within the building, plant open space, plant in a wide channel, equipment placed orderly, is also not smell the smell of cutting fluid. The main equipments are cylindrical grinder, universal tool grinder, and other new tools, machine tools equipped with dust clouds absorber, room is equipped with ventilation facilities. Standard tools of production equipment are equipped with automatic supply and finished sending blank devices (mainly using small robots and conveyor belts), no one can be 24 hours of processing. Most purchased machines were upgraded to accommodate the special needs of the company. In the CNC universal tool grinding machine spindle rotation, with several diamond grinding wheel (diameter, shape, size, combined with different doses), grinding conditions are based on the change in grinding and practical experience in the development of production, there conducive to the continuous production of high precision cutter. ?
Part of the company also produces non-standard products, such as ?10mm helical milling, etc., requiring that their bottom edge, side edge, should be to mirror the level of the rake face. ?
In order to compete in a superior position in the Japanese into the tools the company seeks to texture with excellent production equipment, excellent performance. If the company in order to ensure a small diameter cutter R precision CNC measuring machine used, the indication unit of 0.1?m, can fully guarantee the accuracy of the measurement micron. In order to observe the status of cutter blades, the company used high-precision high-speed rotary scanning electron microscopy of small diameter end mills. This cutter feed per tooth was only a few microns, therefore, it must be extremely sharp cutting edge. With advanced grinding technology, in the grinding process, particles can be guaranteed not to fall off hard, scanning electron microscopy can be conducted on the edge sharp observation from 2000 to 5000-fold magnification, a slight fault, and immediately discovered that the factory will not put any defective products . ?
Company not only on all aspects of production tools (equipment, environment, technology) attaches great importance to and use of tools on the production and processing performance results have verified this with a dedicated high-speed machining centers, machining cutting tools, and test results of some test processing equipment. In case of mold cavity forming process, the company under the machining accuracy, surface roughness, tool life, etc., working out the cutting conditions and molding can be made without grinding the processing requirements, the whole process using CAD / CAM software controls, processing results are quite satisfactory. INTERMOLD 2003 exhibition in Japan into the cutting tool company to conduct the actual demonstration, the use of tools for the company's R0.5 CBN ball end mill, is processed materials 62HRC hardened steel, cutting conditions for speed 120000r/min, into the to speed 5000mm/min (feed per tooth 0.02mm), depth of cut 0.01mm, with oil mist cooling. Demonstrate good results, that's a very excellent tool for product performance. ?
In the 2003 EMO show, on into the tools the company exhibited a number of new products, we feel that the current tool industry is facing "high-speed processing, high hardness materials processing, high-precision machining," the general trend, an unprecedented fierce competition, the company will Small diameter end mills development, production and sales as the main direction of strong tools to the world market expansion. ?
