This has a lage cntact aea t minimize the isk f vibatin ccuing. The asyix sleeve is a split sleeve with a vey pecise lcating functin t achieve the cect cente height. This clamping methd can educe setting up times as well as minimizing the deflectin f bing bas, leading t me accuate machining and bette suface finish when using bing bas with lng vehangs. asy ix gives a fast and simple way t achieve cect indexing f cente height when muntig cylindical bas int the machine, due t its sping laded plunge design. Thee asy ix sleeves ae available f clamping small 5 25 mm bing bas. The cylindical sleeves, 132L type f ISO 9766 adapts, ae t be used n tuning centes. They ae simila in fm t the shanks n sht hle dills and can theefe be used in standad Whistle Ntch and Weldn hldes. These sleeves als fit mant apt adapts type The slt in the cylindical sleeve is filled with a silicn seale which allws the existing clant supply system t be used. The squae shank hldes, with asy ix type 131. ae t be used n cnventinal lathes. The scews tighten the sltted hlde which ensues gd clamping. Type 131 Types 132L Silicn seale ldes iffeent standads lant cnnectin f bing bas. The Tun 111 bing bas (except f cabide bas) have intenal clant supply. The clant cnnects ae intended t be used f extenal cnnectin f clant via a hse.these can als easily be cut ff and used in cmbinatin with ba with flats inside a sleeve when the clant cmes fm inside the tuet. 25

The clamping length shuld neve be smalle than 3 times the diamete f the ba. Select an enteing angle as clse t 90 degees as pssible it shuld neve be smalle than 75 - s as t diect the cutting fces alng the bing ba. s fist pefeence, the indexable inset shuld have a psitive basic shape and a psitive inset gemety t minimize tl deflectin. Select an inset nse adius which is less than the cutting depth. Insets with thin catings uncated insets nmally give lwe cutting fces cmpaed t thickly cated nes. specially imptant when the elatinship L/ is lage. shap cutting edge nmally impves hle quality thugh minimized vibatin tendency. gemety with an pen chipbeake (such as R/L-K knife-edge) can ften be me advantageus f bing. Insufficient cutting edge engagement can give ise t vibatin thugh fictin duing cutting, instead f a clean cutting actin. xcessive cutting edge engagement (lage O and/ feed) can give ise t vibatins thugh tl deflectin. n inset gade with a highe level f tughness may be a cnsideatin in sme peatins s as t cpe with any isks f chip jamming vibatin tendencies. nside altenative tl paths if chip fmatin needs t be impved. 27
