The first part: Research and overcome iron of squirm Mo Zhu (the machine treatment that CGI) place brings challenges iron of squirm Mo Zhu (the application of CGI) grows increasingly. Squirm Chinese ink is cast-iron (the application of CGI) is growing, the cylinder body crock that reachs car derv engine in the lorry especially covers production aspect. Engine stylist used a lot of CGI advantages to improve the performance of fuel efficiency and engine. Compared with groovy casting pig or tall molybdenum iron, its offerred taller intensity weight to compare, fight abrasiveness effectively, thermal conductance and damping sex. -- all these character are need of engine design place. However, manufacturer people the cast-iron more difficult treatment that discovers CGI wants to compare convention. When the metal that when their use treatment casting pig place uses machines fluid to machine CGI, the cutting tool that machines CGI wears away should compare cast-iron fast 90% -- this was caused higher cost and more machine down time. In addition, because cutting speed and feed lead a likelihood to reduce, the handling time of CGI is about to grow than casting pig a lot of. Use special cutting fluid to be able to reduce the difficulty that machines CGI. Understanding why CGI is machined hard. What CGI should machine harder than groovy iron or nodular cast iron is much, in same treatment the condition falls, the wear rate of cutting tool should compare groovy casting pig 30 times bigger. Undertake machining in the rate with arrived fixed especially (250-700 M/min) , what the difference of wear rate can change is most apparent. These high speed treatment are used in the boring that is like engine air cylinder commonly. Come to those who improve cutting tool wear away to design new metal to machine fluid, want to consider to cause the prime cause of the low cutting sex of CGI above all. The main differentia of casting pig and CGI: The different · casting pig of black lead structure wraps the figuration of black lead easy cutting of lozenge shape structure, strengthened cutting function · thereby CGI includes coral or vermicular structural black lead, strength is accordingly greater, and processability can be lower vulcanization manganese (the vulcanization manganese in the different · casting pig of MnS) content (MnS) offerred the good lubricity in cutting treatment, the effect of the MnS when reaching fixed cutting rate especially is more apparent. MnS is not contained however in CGI however, because this CGI does not have lubricity and the advantage that protect cutting tool. (see following micrograph piece) fluid of treatment of very apparent in the casting pig microstructure of as above new-style metal can solve vulcanization manganese this one predicament. Considering adequately to cause the prime factor of function of CGI low treatment, new metal machined fluid technology to had been developed, this technology can improve the cutting tool life in all sorts of craft that machine CGI and quality of spare parts surface. These craft include the boring that successive cutting treatment is like high speed to be used in engine cylinder commonly. Although newest metal machined fluid technology huge to shorten,groovy casting pig and CGI are in the difference on machine treatment function, but the relevant cost when the chance that increases a metal further machines function and cutting is very significant still, persistent research and development. If you are planning to machine CGI, the metallic treatment fluid that had better contact you first please and tool supplier get relevant first-rate metal to machine the proposal of fluid and cutting tool solution. The 2nd part: Data of near future test shows cutting tool wears away had marked improvement to be in 2010, kui overcame chemical company to develop a kind of new metal to machine fluid technology, a kind special designs to raise the machine processability with squirm cast-iron Chinese ink metal machines fluid. When machining CGI, compared with other those are used in normally general and cast-iron medium metal machines fluid, its huge lowered cutting tool wear rate. Nextpage is in the wear rate that high speed checks cutting tool below the circumstance of successive cutting. To prove QUAKERCOOL 7020®The function of CG, we undertook turning in 450 class CGI (successive cutting) machine treatment checks, cutting tool of steel of use hard alloy undertakes machining below the rotate speed of 250 M/min. In addition, still checked general cast-iron metal to machine fluid to reach a fiducial data consults for research. Dry cutting (without oil) the test also is used assess the disparate impact that wet cutting place does to bring in be being machined here. The graph sees the wear out condition that appears on the cutting tool below the circumstance that machines in same opportunity on, hind of knife face wear away to appear very quickly, final and whole bit wore away. Cutting fluid function - @250m/min of hard alloy cutting tool restrains chemical company about Kui: Understand more information to visit Quakerchem please. Com.
