1 Updte B158J Expnded s New Chip Breker s for Turning Breker Offers the best performnce for utomotive prts pplictions! ysmooth chip control even t vried depths of cut, feeds nd cutting speeds!

2 New Chip Breker s for Turning Breker y Outline When copying, cutting conditions such s the depth of cut, feed rte nd cutting speed cn vry. This cn led to number of problems nd reduce efficiency: Ineffective chip control due to the use of one breker style. Mchine down time due to chip jmming. Poor tool mngement due to the use of numerous insert geometries. breker uses unique geometry tht provides effective chip control over wide ppliction re. It lso improves wer resistnce becuse of lower het genertion during cutting, therefore contributing to lrge increse in productivity. y Fetures The peninsul provides effective chip control if the wings become worn. The wings re strtegiclly locted to dely wer propgtion nd give effective chip control even s the insert wers. The steep slope on the inner side of the winged sections chieves improved chip control t smll depths of cut. Wide chip pocket to llow effective chip control nd reduced cutting resistnce. The breker is vilble in high performnce grdes UE6105, UE6110, UE6020 nd! y Anlysis: Chip geometry nd cutting edge tempertures Low cutting het reduces crter wer! Lower workpiece tempertures led to higher dimensionl ccurcy!

Plese mchine within the recommended ppliction rnge nd exchnge expired tools with new ones in dvnce of brekge. Plese use sfety covers nd wer sfety glsses. When using compounded cutting oils, plese tke fire precutions. When ttching inserts or spre prts, plese use only the correct wrench or spnner.
