Abstract
A lead face machining apparatus for machining a lead face on a cylindrical workpiece. The apparatus includes a spindle unit having the workpiece rotatably mounted on it, an end cam provided rotatably together with the spindle, a first slide table and a second slide table such that each of the spindle unit, first slide table and second slide table has a static pressure fluid bearing structure. The apparatus is further provided with means for supplying fluid to the static pressure fluid bearings in common, whereby the workpiece is least subjected to vibration produced through contact of the end cam by a lead machining unit for machining the workpiece.
