Abstract (en)
[origin: WO8203039A1] A spindle tilting control device for a plane and spherical rotary grinding machine, fine gliding machine, lapping machine and polishing machine, which are super precise machines for manufacturing microminiature electronic part components, which device employs a joint (7) for tilting a spindle, can perpendicularly secure a rotary table (1) with respect to the spindle (3) by clamping crank bolts (4), (5), tilts a grindstone or surface plate (2) with a spindle tilting joint (7), thereby machining a spherical surface together with electric and chemical methods. This machine can extremely precisely machine semiconductor material, magnetic material, ceramics, superhard alloys, or the like.
