Abstract
A method for machining a groove in a sealing member and the edges of the groove. A tool 24 is formed with a top portion 24 having cutter sections 23A, each defining a cutting edge 23 for machining a groove in a scroll wall of a scroll member, and a tapered part 25 having cutter sections 26A, each defining a cutting edge 26 for bevelling the edges of the groove and the edges of the scroll wall. The groove 9 and edges 11 are simultaneously machined.
Claims8
A method for machining a scroll member having a base plate having an axis and a scroll wall extending axially from the base plate, comprising steps of:
- providing a tool having a first cutter part of a substantially straight cylindrical shape and a second cutter part of a tapered cylindrical shape extending from the first cutter part;
- holding the tool while allowing a relative movement of the tool with respect to the scroll member in a first plane parallel to the axis of the tool and in a second plane transverse to the axis of the tool;
- causing the tool to be moved in the first plane, so that the first and second cutter are engaged with an end surface of the scroll wall at respective desired depth, and;
- causing the tool to be moved in the second plane, while the tool is rotated, so that a groove is formed at the end surface of the scroll wall by the first cutter part of the tool, while edges of the groove is bevelled by the second cutter part of the tool simultaneously with the machining of the groove by the first cutter part.
A method for machining a scroll member having a base plate having an axis and a scroll wall extending axially from the base plate, comprising steps of:
- providing a tool having a first cutter part of a straight cylindrical shape and a second cutter part of a tapered cylindrical shape extending from the first cutter part;
- providing a chuck for holding the scroll member;
- providing a support of the tool;
- a holding, on the support, the tool while allowing a relative movement of the tool with respect to the scroll member on the chuck in a first plane parallel to the axis of the tool;
- holding, on the chuck, the scroll member while allowing a relative movement of the scroll member with respect to the tool, in a second plane transverse to the axis of the tool, by means of a relative movement along X-axis and Y-axis and a rotating movement in the second plane;
- causing the tool to be moved in the first plane, so that the first and second cutter are engaged with an end surface of the scroll wall at respective desired depth, and;
- causing the tool to be moved in the second plane, while the tool is rotated, so that a groove is formed at the end surface of the scroll wall by the first cutter part of the tool, while edges of the groove are bevelled by the second cutter part of the tool simultaneously with the machining of the groove by the first cutter part.
