在液压元件生产中,精密阀孔的工艺方法和质量是非常重要的。如果孔的几何精度、表而光洁度、孔径的最终尺寸等等不能稳定在技术要求范围内,这会给选配阀芯保证与阀孔的一定间隙,带来很多麻烦。虽然目前各厂的条件不同,但是探索和采用先进工艺,不断提高产品质量目的是一致的。因为先进的工艺是提高产品质量的保证。但就目前情况来说,工艺水平相对地落后于设计水平。一、目前通孔阀孔采用的几种工艺阀孔的工艺方法是在生产实践中经过逐步改进和完善起来的。各种精密孔的工艺,在不同时期均发挥了各自的优点,起过一定作用。例如:早期都采用研磨工艺,后来相继出现推
In the production of hydraulic components, precision valve hole process and quality is very important. If the geometric accuracy of the hole, surface finish, the final size of the aperture, etc. can not be stabilized within the technical requirements, it will cause a lot of trouble for the selected valve core to ensure a certain gap with the valve hole. Although the conditions of the various plants are different at present, the purpose of exploration and adoption of advanced technology and continuous improvement of product quality are consistent. Because advanced technology is to improve product quality assurance. However, in the current situation, the technological level is lagging behind the design level. First, the current through-hole valve hole used in several process valve hole in the production process is gradually improved and perfected. Various precision hole technology, at different times have played their own advantages, played a certain role. For example: Early use of grinding process, followed by one after another push
