机床导轨的刮削精度对工件的加工精度和机床本身的使用寿命有很大关系,尤其对精密机床和仪器的床身导轧更是如此,因此改进刮刀以提高刮削精度有一定的现实意义。现将我们的经验介绍如下:一、弯头刮刀、直刮刀和勾头刮刀(1)弯头刮刀:这是过去最常用的一种,如图1所示。操作时将刀柄顶在腹部,左手压紧刀头,右手握住刮刀中部进行
The scraping precision of the machine tool guide rail has a great relationship with the machining precision of the workpiece and the service life of the machine itself, especially for the bed rolling of precision machine tools and instruments. Therefore, it is of practical significance to improve the scraper to improve the scraping accuracy. Now we introduce the experience as follows: First, elbow scraper, straight scraper and hook scraper (1) Elbow scraper: This is the most commonly used in the past, as shown in Figure 1. Operation will be the top of the shank in the abdomen, the left hand squeeze the blade, the middle of the scraper to hold the right hand
