目前所使用的车刀大部分都是硬质合金的,如何有效地利用硬质合金,是一项很重要的工作。在机械加工车间用得最广的有这几种:1)平面偏刀;2)外圆偏刀;3)主偏角为90°的外圆偏刀;4)弯头车刀。过去都是把硬质合金平焊在刀杆上,刀片的利用率很低;以后我们改进了方法,把刀片横焊在刀杆上。图1中的甲、乙、丙、丁、是改进前的车刀;图2中的甲、乙、丙、丁是改进后的车刀。改进后的优
At present, most of the turning tools used are cemented carbide. How to make effective use of cemented carbide is a very important task. In the machining shop are the most widely used in these categories: 1) plane partial knife; 2) eccentric knife; 3) the main declination of 90 ° external circular knife; 4) elbow turning tool. In the past, cemented carbide was flat-welded to the arbor, and the utilization of the blades was very low. Later, we improved the method by horizontally welding the blades to the arbor. Figure 1, A, B, C, D, is to improve the turning tool before; Figure 2 in A, B, C, D is improved turning tool. Improved excellent
