液压阀孔的精加工,多年来,一般采用的工艺是:铰削→研磨→抛光。这种工艺的加工效率低,废品率高,加工质量难以保证。为了改变这一落后工艺,天津市液压件厂和天津砂轮厂、天津制刷厂合作,研制出电镀超硬磨料镗磨工具和挠性磨孔器(见图1)。从而使阀孔精加工工艺改为:刚性镗铰→电镀超硬磨料镗磨工具珩磨→挠性磨孔器抛光。 Hydraulic valve hole finishing, over the years, the general process is: Reaming → grinding → polishing. The process of processing low efficiency, high reject rate, processing quality is difficult to guarantee. In order to change this backward technology, Tianjin Hydraulic Parts Factory and Tianjin Grinding Wheel Factory, Tianjin Brushes plant cooperation, developed a superhard abrasive plating tool and flexible grinder (see Figure 1). So that the valve hole finishing process to: Rigid boring hinge → plating super-hard abrasive boring tool honing → flexible abrasive polishing machine.
