圆盘槽铣刀是我厂生产钻头、丝攻的重要工具。为了保证和提高它的使用寿命,必须在热处理时要对它进行炉前金相的检测。由于它的形状所定,不能在它的齿部,而要在它的端面上进行磨制看金相,这项工作不大容易掌握,磨不好金相组织显示不出米。为了解决这个矛盾,本人根据实际经验,现总结以下几条: 1.槽铣刀经淬火冷却后,先在热水中把残盐洗净、擦干,再用砂轮机把刀具的一端面的局部轻磨一下,磨去刀具的表面脱碳层。
Disc groove cutter is my factory production drill, wire tapping an important tool. In order to ensure and improve its service life, it must be carried out in the heat treatment before the furnace metallurgical testing. Because of its shape, it can not be in its teeth, but to wear on its face to see the metallographic phase, the work is not easy to grasp, not wear out of the metallographic microstructure shows no. In order to solve this contradiction, I based on actual experience, are summarized in the following articles: 1. Groove milling cutter after quenching and cooling, the first salt in the hot water to wash, dry, then the grinder to one end of the face Local light grinding, wear off the surface of the decarburization tool.
