Beijing porcelain uses tool of CVD plated film in steel treatment " CA55 " in series add newly " CA5505 " and " CA5535 " 2 kinds of model, will in June 2005 the last ten-day of a month appears on the market. Former use at high speed · to be machined continuously, latter is used at heavy cut · strong intermittent treatment. The general · before cooperating this is weak intermittent treatment is used " CA5515 " with general · intermittent treatment is used " CA5525 " , aux will be able to satisfies extensive steel to machine utility. The price all is in 2205 yen of 483 yen ～ (add up to a RMB about 37 yuan of ～ 170 yuan. Contain tax) between. The department labelled CA55 to raise dependability, cut manufacturing cost, mother capable person did hard to exceeding alloy to have columnar the processing of CVD plated film of particle structure, rose to machine efficiency considerably from this. This new the adjustment that supplementary CA5505 basically faces rolled steel cutting treatment, came true to exceed the cutting rate that 300m/ assigns. And CA5535 applies to what can cause heavy load to the tool to spread out different component to machine (intermittent treatment) stable treatment. Compare with original tool photograph, the end panel in alloy steel is intermittent the service life of about 2 times came true in treatment CNC Milling
