Gao MJ screw hole cutting tools to extend the life of the improvement program
Since January 2008, MJ screw holes with a lower loss teeth, and the value of surface roughness is high, and the processing occurs after the thread can not pass regulatory situation, accelerated wear tool, processing an average of 15 to 30 is the ATC. site-specific circumstances, the final design of the key for the two breeding programs.
(1) Option 1 and disappeared from the tap, after re-grinding the surface coating.
Under current circumstances, it is lower thread diameter control on the roof to reduce wear on the faucet, the improvement of everyday life. In touch of inventory that enables Copyright MMSonline.com.cn at present the least possible tap use heavy grain, due to enjoy life after heavy grinding inconsistent, prone to mass production of threaded screw holes in individual cases no, but also increased inspection and repair workload. If I had to use touch heavy grain, after re-grind the surface coating, touch the larger diameter to ensure that tap pitch diameter.
Currently has a small tap diameter or processing of the first piece of Japan recently OSG thread does not touch, in charge of measuring meter tap Dongfeng plant used again after crushing the topsoil, Japan OSG taps can surface coating, painted diameter of 6 m, to check the eligibility process, and collect touch the life situation.
(2) Scenario 2 with the new key in the method of increasing the diameter 0.01 mm, respectively Dongfeng factory measuring meter Japan, OSG, Wuxi New Diamond Age and Zhuzhou cemented carbide taps for experiments.
Measuring plant taps Metro Company Dongfeng
Materials common tools are high speed steel, improving the pre-install a new blade can process 30 processing of the surface roughness can screw hole meet the requirements to ensure through regulations only pass inspection. Milling of the surface layer of the old faucet, about 30 pieces of life, relatively roughness of the surface high. The main reason may be due to post-industrial automation tap layer network edge will become blunt, which is on the edge not very strong cutting, resulting in higher surface roughness.
Has to take in diameter at the base of the original and the increase of 0.01 mm 0.02 mm, each produced 10 tries. The first test of 0.01 mm in diameter to increase the tap (K23D2-128C) (Test hole No. 6003,6005,6007,6009,6011,6013 and 6015), first hole 6007 article inspection regulations are only two buckles, the rest is qualified, so far has processed more than 220 (puncture diameter can not increase the pre-processing 25 or less), judging by wear on the tap, you can continue processing.
Later in the tap tap 0.02mm diameter increase was tested (K23D2-128D) (Test hole No. 6003,6005,6007,6009,6011,6013 and 6015), first inspection rules that Article 6007 only the holes in 4 button on the left and right, others were qualified, the short life of 300 pieces.
Judging from the above two tests, tap, and the increase of larger diameter 0.02 mm 0.01 mm, with the exception of 6007, the others are going through the hole machining, the spindle 6007 may be due to higher rate, resulting in only two tests were both in the regulation of 2 buttons and the 4 button. 0.01 mm in diameter increased after the tap, tap of life increased from 25 to about 220 now, life has been an increase substantial tap, tap tap change in the path of life itself has a significant impact.
In order to explore the economic size of the diameter and more adequate and the tap tap of material has accumulated experience in processing threads MJ, January 14, 2008, which provides an increase of 0.015mm diameter 400 of the tap waiting for the test.
Japan Taps OSG
The tool is sensitive to temperature change, summer temperatures are high fashion a knife can produce 200 to 300, but winter can only produce 60 to 70, and threaded holes for surface treatment of high roughness.
Tap is made of HSSE (including cobalt steel high speed), coating the surface, life is about 20, the surface roughness is relatively low, the new arrival of the first pieces of a group of touch in through rules processing into the situation there.
Wuxi touch new era
regular high speed steel cone, put a knife to produce 50 to 60, but the quality of the cutting tool metal mixed network, the size of a very unstable load 12 knives usually have 1 / 3 of the screw hole is not helpful. Because This tool is very unstable product quality, treatment, test results is not obvious.
Zhuzhou Cemented Carbide Taps Diamond
Adjust the gain Zhuzhou cemented carbide tap diameter designed 30 experiments, according to statistics of production have been processed more than 2,200 qualified Kong still use and the treatment of surface roughness hole screw.
The study implies that moc.swenaii.www, Dongfeng measuring measuring instruments designed steel plant in Zhuzhou High Speed Diamond Cemented Carbide Taps Cone and most successful experiment, carbide cutting tools in the unit price in terms of a simple tool high speed steel 20 times, but life is several times Carbide high-speed steel, which reduces the cost and improve economic efficiency.
All rights reserved comprehensive industrial automation network in a reasonable tool to improve the use of tools, the use of advanced tools for improving product quality and reduce costs is beneficial. About the Author
