Method for machining shoe pocket for piston in variable displacement swash plate type compressor |
摘要 |
A method for machining a pair of shoe pockets for piston in a swash plate type compressor is disclosed. In this method, the shoe pockets are respectively formed on the opposed walls of the slot in the piston of the compressor while conforming to a single imaginary sphere. The method comprises the step of moving a cutter provided with an arc-shaped cutter blade that has a rotation diameter less than the width of the slot. Thereafter, there is performed the step of relatively revolving the cutter with regard to the piston by allowing the central axis of a revolved part to move along a circular orbit within the slot while rotating the cutter, so as to cut the shoe pockets to conform to the single imaginary sphere. Finally, the step of retreating the cutter out of the slot when the cutter completes one round revolution and is returned to its initial position is performed.
