许多无心磨床(如M1080、XF004)的泄油回路中和整体式液压操纵板中都有直角通油道见图1。机床工作时,液压油由于氧化析出沥青和其它沉淀物。时间长以后,直角通油道容易被这些物质堵塞,从而导致机床不能正常工作。有条件的单位可用高压空气排除,但效果不理想,因这些物质容易粘附在通油道表面。我们在维修中发现以下方法排除直角通油道的油
Many centerless grinders (such as M1080, XF004) drain circuit and integral hydraulic control plate has a right angle through the oil see Figure 1. Machine work, the hydraulic oil due to the oxidation of asphalt and other precipitates. After a long time, right angle through the oil is easily blocked by these substances, resulting in machine tools can not work properly. Conditional units can be excluded by high-pressure air, but the effect is not satisfactory, because these substances easily adhere to the surface of the oil passage. We found the following methods in the maintenance of right-angle oil passage of oil
