ONETAP tap suffers the appearance of patent protection to be made according to hi-tech standard, have the following advantage: Reduce and decompose cutting load well, block of efficient pass the time in a leisurely way the overload of tap; Ensure tall by treatment surface quality, cutting treatment behaves stability; Compare at current tap, life of ONETAP tap cutting tool is highest amount to its double (still depend on cutting parameter and workpiece material) . Offer the following two kinds of general tap: Snail pointed tap -- the treatment that is used at via; Tap of chamfer of helix platoon bits -- the treatment that is used at blind aperture. 1. Snail pointed tap: Snail pointed tap will cut bits to be advanced ahead; Use at the treatment of via. Design of shallow the chamfer that discharge bits makes tap solidder. Tap straight chamfer is used at the drainage of cooling fluid only, need not at discharging bits. Characteristic: Straight chamfer is used at drainage cooling fluid; Make awl part: B (of 4-5 head whorl pour wine cup) ; – of helix shape sharp angle is driven ahead cut bits; Blade is as long as diameter of 3 times whorl; Use extensively at great majority to be machined the efficient tap of material. 2. Helix discharges bits chamfer tap: Blind aperture studies optimal option of silk. Give attention to two or morethings discharges bits and refrigeration to flow. Characteristic: Used very general 40 ° dextral helix angle; Tap of HSS-E blind aperture; Pour horny guiding: C- (2-3 head whorl pours wine cup) ; Blade is as long as diameter of 3 times whorl; Use extensively at great majority to be machined the efficient tap of material. Two tap all use blame coating polish to handle high-speed steel HSS-E to be made. If need TiN, tiCN and TiAIN coating or finishing (chemical vapour is handled) , raise a requirement when order please. Form of ONETAP tap tooth: – of · ISO is metric 6H of grade of public errand of DIN 13 - of thick tooth whorl.
DIN 371 standard (M2-M10) reach DIN 376 (M11-M30) ; – of · ISO is metric 6H of grade of public errand of DIN 13 - of fine tooth whorl.
DIN 374; – of · UNC is US-made thick tooth whorl (TPI) - 2B of tolerancepublic errand grade; · DIN 371 (#4 - 3/8) and DIN 376 (7/16 - 1 " ) ; – of · UNF is US-made fine tooth whorl (2B of grade of public errand of TPI) –; · DIN 371 (#4 - 3/8) and DIN 374 (7/16 - 1 " ) . Use tap of Yi Sika ONETAP can reduce the amount that is used at all sorts of tap that be reached by treatment material to apply place to need tap considerably, those who achieve economy is efficient make.
