It is further characterized in that:
Described adjustable pivot structure is specially bolt arrangement, and the upper end head of the described bolt arrangement under tightening state presses the upper surface of described headstock, in the locating hole of described feed slide only lower end have internal thread;
Described trimmer is specifically grinding wheel arc dresser.
After adopting the present invention, headstock is installed by adjustable pivot structure and feed slide, and 0 °～40 ° of the relative feed slide angle ranges of headstock, make can the have °～40 ° of adjustment of the center line of magnetic holding device and X-axis guide rail, the electricity main shaft is perpendicular to the Y-axis guide rail, during work, the bistrique slide plate arrives first trim locations, feed slide is walked trim amount, trimmer starts trimming wheel automatically, feed slide return back to original position afterwards, the bistrique slide plate is to the grinding position, feed slide enters the grinding position, headstock is adjusted angle, guarantee the Internal Spherical Surface centre of sphere of the axis of rotation of grinding process medium plain emery wheel through workpiece, wherein by feed slide, along the X-axis guide rail movement, control the sphere size, grinding forms the qualified sphere that a bearing requires, after the emery wheel abrasive wear, can be removed by trimmer, can not affect grinding next time, it is for improving the precision of self-aligning bearing, also can replace the self-aligning bearing Superfinishing machine to complete superfinishing, make the superfinishing of Internal Spherical Surface bearing only need a grinding to complete, grinding efficiency is high.
