M 2116型内圆磨床是一种简易型机床,主要存在着液压系统开车冲击和低速爬行两大问题。本文介绍的预先充压是解决开车冲击和低速爬行的一条较为有效和实用的途径。 一、改装的思路和原则 我们对原机床提供的液压系统原理图(图1)进行了研究,似乎可以看出有一条管路经开停阀I的第
M 2116-type internal grinder is a simple type of machine tool, there are two main problems hydraulic system driving impact and low-speed crawling. The pre-charge described in this paper is a more effective and practical way to solve the driving shock and low-speed crawling. First, the modified ideas and principles of the original hydraulic machine we provide the schematic diagram of the system (Figure 1) were studied, it seems we can see there is a pipeline by the opening and closing valve I
