Broach of high-speed steel fried dough twist is industry is mixed civil use most bore tool. Twist drill is born more than 100 years to come, material and craft progress ceaselessly, but its are basic figure is rare however and major improve. 20 centuries 50 time, our country was invented for the representing's group with Ni Zhifu group auger, of broach of will common fried dough twist get a needle to repair wear " 3 needles 7 blade " appearance (graph 1) , improved the performance characteristics of broach and cutting life greatly, great echo is caused in bound of domestic and international cutting, comrade Ni Zhifu goes to hamster to perform group sensation was caused when getting. But group plunge knife model complex, rely on to repair cross to be produced in order to realize industrialization by hand, this restricted group of wide application that get undoubtedly. A.

Get steel to use group get B.

Auger cast-iron with group get C.

Chamfer of many minutes of bits group get D.

The cross is repaired grind group get E.

Double hind horn group get a picture of 1 different form group auger (two kinds of of A ～ C) and common broach forms that get a tip 20 centuries 90 time, expert of cutting tool of beautiful book foreign citizen of Chinese origin Dr. Wu Xianming's directive technology group was American Irwin company to develop similar group of much blade awl that get head and get a needle to build the numerical control grinding machine that grind, rolled out product of head of much blade awl. At the beginning of this century, excellent broach limited company designed our country Hainan special device, the industrialization that realized much blade needle to get an efficient, high accuracy, low cost is repaired grind, broke through group of bottleneck that get industrialization. Should make truly nevertheless group get a brand to be in even coating of raw material, workmanship, surface and auger model the respect such as further innovation makes thorough effort. Advantage technology of home, those who advance Chinese own intellectual property group get technical industrialization, mixed in January 2004 in March, association of technology of cutting tool of cutting of metal of Chinese machinist job is in early or late Hunan university and limited company of tool of Jiangsu Nature's engineering are held group get attune of industrialization seminar chime to meet. Come from Nature's engineering tool, Hainan the controller of enterprise and the college such as college of industry of grain of university of excellent, Hunan, Wuhan university, Beijing, expert attended the meeting, the developer of awl of much blade of the still has Professor Wu Xianming student that attends the meeting on invitation, United States is beautiful book Chinese Dr. Sha Jilun. Attended the meeting to just be reached each " group get industrialization to carry out compendium " , its are overall train of thought is: Strengthen cooperation, integrated home is made in high-speed steel material, broach, auger model optimize, get a needle to repair grind the mature advanced technique that waits for a respect, advance quickly group get industrialization course. Attended the meeting to just reach multinomial collaboration intent each, limited company of Nature's engineering tool is contributive 200 thousand yuan are built group get industrialization fund, with support industrialization is coordinated and technical development works. Express 67 model group auger get with excellent QB-2003 model the blade inside ARc of the horn after circular arc of Ac of the horn after the blade outside Gc of the horn before the blade inside Y of bevel of horizontal blade of 2Øt of sharp angle of the blade inside 2Ø of sharp angle of the blade outside long By of horizontal blade of long L of the blade outside R of radius of circular arc of comparative pointed tall H.

Be in 67 model group undertook much azimuth innovates on the base that get (see watch and graph 2) development go get it is better to cut lighter, centering, can get armor plate to be able to drill deep hole again already, can get iron and steel already again. They still established industry standard, promote product of much blade awl to the international market group by group with broach manufacturer collaboration. The dominant position that group of Jiangsu Nature's engineering creates with material of its high-speed steel and broach, developed the 2nd generation new-style product of much blade awl, with " TG " own brand (win Chinese celebrated trade mark 6 years) stay in Europe, additional cost also had the technology of broach product to promote greatly. As the progress of cutting technology, portion is in cutting tool of hard alloy cutting tool, pottery and porcelain and the market that transcend strong cutting tool to increase ceaselessly. And high-speed steel cutting tool good with its tenacity, the crucial point is sharp etc the advantage is making complex cutting tool, Kong Jia the respect such as the material treatment of labour cutting tool and sclerosis of a few easy treatment still has its advantage, inspect entirely of high-speed steel twist drill consequently cheap cutting tool also is not comprehensive. World-renowned Guhring and Titex are producing high-speed steel bit, of industrial level, of professional class be in with broach of civil high-speed steel Euramerican have huge market, and the world's greatest flying mechanism builds business Boeing company to also want to use twist drill head. The key is the quality that should improve homebred twist drill hard, for home treatment industry offers the product with good performance and enter market of Euramerican industrial product. Hainan is excellent be in with Jiangsu Nature's engineering group of result that get the place on industrialization to obtain be to be worth us to draw lessons from. Group the industrialization course that get develops to development even. We want gather home's top-ranking technology group, begin extensive technical collaboration, build group get industrialization base; Should move toward groove from the onefold innovation that get a tip model, the comprehensive innovation of structure, material and workmanship; Want a performance broach of common fried dough twist, appearance distinguishs apparent excel apparently at having bit new-style head of much blade awl is pushed to the market, push to the world, to promote the tool enterprise of our country, construction makes powerful nation make due contribution.
