Abstract:
A method for machining a groove at an axial end surface of a scroll wall of a scroll member of a scroll compressor, the axial end surface extending along a spiral direction, the scroll wall having, at a radially inner part thereof, a width which is larger than the remaining part of the scroll wall, said method comprising the steps of:providing a milling tool having an outer diameter corresponding to a width of the groove to be machined;axially introducing the milling tool into the axial end surface of the scroll wall at a radially outer location thereof to obtain a desired cut depth;moving the milling tool inwardly along the spiral direction of the scroll wall, so as to create a groove of a width corresponding to the outer diameter of the milling tool until the tool comes to the radially inner location of the scroll wall having the increased width, and;moving, when the tool comes to the radially inner part of the scroll wall having the increased width, the milling tool along a closed loop path, so as to create a groove of a width larger than the outer diameter of the milling tool, while leaving, inwardly of the closed loop path, a portion un-machined.
