APPARATUS FOR PROCESSING INNERSHERSPHERICAL SURFACE, HAVING AUTOMATIC OIL SUPPLIER

摘要

PURPOSE: An apparatus for processing an inner spherical surface is provided to improve the surface roughness of a workpiece by preventing a bite from shaking and to automatically supply oil by an automatic oil supplier for the smooth reciprocating motion of a cutter. CONSTITUTION: An inducer(30) supplies lubricating oil to a face touching with a piston(8) and a holder(42) of a spherical surface processing apparatus through a supplying channel(21) of a connecting shaft(16) and an oil outlet channel(10) formed on the outer circumference of the piston. The supplied oil makes the rectilinear movement of the piston smooth. A check valve(12) prevents oil from backflowing and a key fixes the connecting shaft and the piston.
