* Read from slide……….. Stress the increase TIR on the weldon collet systems vs. the “precision” systems……. * Prerequisite 2: Rigid holding system The carbide tool is stiff and thus – unlike tools with steel bodies – the tool body cannot compensate for any effects of unbalance in the holding system. Therefore, a well-balanced and rigid tool-holding system is a must. Runout is then the important factor, since it has great effect on both surface finish and tool life. CoroGrip is example of an excellent choice of tool holder. It offers a maximum runout of only 0.002-0.006 at a tool protrusion (outstick) of 3 times the mill diameter! However, runout is not only caused by the tool holder, but all the items between the tool holder and the machine spindle, i.e. the modular holding system and any extenders, add to the total runout value. This means that each coupling should have as little runout as possible in order to meet the acceptable total value of 0.0008 mm – or, preferably, 0.0004”. A good rule of thumb: For every 0.01 mm (= 10 microns) increased runout, the tool life decreases by 50%. This is important to bear in mind when choosing a collet chuck, which can have a runout of up to 0.04 mm. * Read from slide………. * * The BEST ……………..read from slide………. * Read from slide….. * Read from slide * Read from slide * Read from slide /* 0.01 -50% T，每增加0.01mm跳动刀具寿命减小50％ 刀柄跳动 0 20 40 60 80 100 100 80 60 40 20 0 刀具寿命 圆跳动 ％ /* 红色 = 差的 TIR 蓝色 = 好的 TIR 表面质量跳动对表面精度的影响 TIR（径跳动）直接影响表面质量.
