在1K282型半自动车床上大批加工装卸机液压机缸盖时,必须保证φ105.8A_3、80A_4和64A_3三孔的同心。利用在刀杆上装一组如图所示的镗刀块同时精镗各孔,可方便地达到这一点,而且可提高加工精度,降低刀具材料消耗.刀块由刀体2和3、5两把刀头组成,后者相对于前者的中心孔对称磨锐,并可用螺钉4进行调整,以便根据磨损程度来恢复其所需尺寸,然后用螺钉1固定.刀片采用T15K6硬质合金。使用时,把刀块装在刀杆长方形孔中,用
In 1K282 semi-automatic lathe large batch processing hydraulic machine cylinder head, you must ensure φ105.8A_3,80A_4 and 64A_3 three holes concentric. The use of a set of boring bar on the arbor as shown in the figure at the same time boring fine boring holes, can easily achieve this, but also improve the machining accuracy and reduce tool material consumption knife by the knife body 2 and 3,5 two The tip is made symmetrically sharpened with respect to the center hole of the former and can be adjusted with a screw 4 to restore its required size to wear and then secured with a screw 1. The insert is T15K6 cemented carbide. Use, the knife block installed in the rectangular hole cutter, with
