Patent ID: 7540726

Claim:
A method for machining a scroll wrap, comprising: forming a stationary scroll having a stationary end plate and a stationary scroll wrap extending from said stationary end plate, said stationary scroll wrap of said stationary scroll having a side face, forming a slewing scroll having a slewing end plate and a slewing scroll wrap extending from said slewing end plate, said slewing scroll wrap of said slewing scroll having a side face, wherein said side face of said stationary scroll wrap and said side face of said slewing scroll wrap are configured to slide with respect to each other in use, wherein said side face of said stationary scroll wrap and said side face of said slewing scroll wrap each has a height extending from a respective one of said stationary end plate and said slewing end plate to a distal end; and non-rotating-tool machining said side face of one of said stationary scroll wrap and said slewing scroll wrap by moving along a longitudinal direction of said one of said stationary scroll wrap and said slewing scroll wrap a non-rotational blade such that said height is machined at one time, wherein a cutting edge of the non-rotational blade has a curved profile which is transferred to said height such that an optimum shape is provided when the one of said stationary scroll wrap and said slewing scroll wrap is driven in a compressor generating heat and pressure, and wherein said cutting edge has a length greater than the height of said one of said stationary scroll wrap and said slewing scroll wrap.
