为了减少磨损区的宽度，提高铣刀（涂层和未涂层）的刀具寿命，断屑器螺纹在高速钢铣刀上研磨。到目前为止，断屑器螺纹是用金属结合剂砂轮研磨的，而砂轮不能在原磨床上转动，而是必须在单独的仿形机上进行修整和修整。由于永久性的轮廓磨损，必须经常从磨床上拆下砂轮以校正其轮廓。本文介绍了一种在一台数控磨床上进行修整、检查和调整的系统。最适合这种应用的磨削工具是陶瓷结合剂CBN砂轮，它可以很容易地修整到所需的每一个轮廓。

TO REDUCE THE WIDTH OF WEAR LAND AND TO INCREASE THE TOOL LIFE OF MILLING CUTTERS (COATED AND UNCOATED) CHIP BREAKER THREADS ARE GROUND ON HIGH-SPEED STEEL MILLING TOOLS. UP TO NOW, THE CHIP BREAKER THREAD WAS GROUND USING METALLIC BONDED GRINDING WHEELS, WHEREAS THE WHEEL COULD NOT BE PROILED ON THE ORIGINAL GRINDING MACHINE, BUT HAD TO BE TRUED AND DRESSED ON A SEPARATE PROFILING MACHINE. BECAUSE OF THE PERMANENT PROFILE WEAR, THE WHEEL HAD TO BE REMOVED FROM THE GRINDING MACHINE FREQUENTLY TO CORRECT ITS PROFILE. THIS PAPER INTRODUCES A SYSTEM WHICH PROVIDES DRESSING, CHECKING, AS WELL AS ADJUSTING WITHIN A SINGLE CNC-CONTROLLED GRINDING MACHINE. THE MOST SUITABLE GRINDING TOOLS FOR THIS APPLICATION ARE VITRIFIED BONDED CBN WHEELS WHICH CAN EASILY BE DRESSED TO EVERY PROFILE REQUIRED.
