Abstract
Abstract A device for magnetic-abrasive machining of a part has the steps of forming a magnetic field, arranging a part to be machined in the magnetic field, supplying a magnetic-abrasive powder in a machining zone toward a surface of the part to be machined, and supplying a fluid jet under pressure toward the magnetic-abrasive powder so as to move the magnetic-abrasive powder relative the surface of the part to be machined.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
71 words
A method of magnetic-abrasive machining of a part, comprising the steps of forming a magnetic field; arranging a part to be machined in the magnetic field; supplying a magnetic-abrasive powder in a machining zone toward a surface of the part to be machined; and supplying a fluid jet under pressure toward the magnetic-abrasive powder so as to move the magnetic-abrasive powder relative to the surface of the part to be machined.
Claim 2
Independent Claim
71 words
A method of magnetic-abrasive machining of a part, comprising the steps of forming a magnetic field; arranging a part to be machined in the magnetic field; supplying a magnetic-abrasive powder in a machining zone toward a surface of the part to be machined; and supplying a fluid jet under pressure toward the magnetic-abrasive powder so as to move the magnetic-abrasive powder relative to the surface of the part to be machined.
Claim 3
Dependent Claim
37 words
A method as defined in claim 1, wherein said supplying a fluid jet includes supplying the fluid jet so that the fluid jet presses the magnetic-abrasive powder to against the surface of the part to be machined.
Claim 4
Dependent Claim
37 words
A method as defined in claim 1, wherein said supplying a fluid jet includes supplying the fluid jet so that the fluid jet displaces the magnetic-abrasive powder relative to the surface of the part to be machined.
Claim 5
Dependent Claim
37 words
A method as defined in claim 3, wherein said supplying a fluid jet includes supplying the fluid jet so that the fluid jet rotates the magnetic-abrasive powder relative to the surface of the part to be machined.
Claim 6
Dependent Claim
55 words
A method as defined in claim 1, wherein said supplying a fluid jet includes supplying the fluid jet so that the fluid jet presses the magnetic-abrasive powder to the surface of the part to be machined and at the same time displaces the magnetic-abrasive powder relative to the surface of the part to be machined.
Claim 7
Dependent Claim
54 words
A method as defined in claim 1, wherein said supplying a magnetic-abrasive powder includes accommodating the magnetic-abrasive powder in a temporary receptacle and attaching the temporary receptacle to said means for generating a magnetic field, so that thereafter the magnetic-abrasive powder leaves the receptacle to be supplied to the surface of the part machined.
Claim 8
Independent Claim
77 words
A device for a magnetic-abrasive machining of a part, comprising means for generating a magnetic field; means for placing a part to be machined in the magnetic field; means for supplying a magnetic-abrasive powder into a machining zone onto a surface of the part to be machined; and means for supplying a fluid jet under pressure to the magnetic-abrasive powder so as to move the magnetic-abrasive powder relative to the surface of the part to be machined.
Claim 9
Independent Claim
77 words
A device for a magnetic-abrasive machining of a part, comprising means for generating a magnetic field; means for placing a part to be machined in the magnetic field; means for supplying a magnetic-abrasive powder into a machining zone onto a surface of the part to be machined; and means for supplying a fluid jet under pressure to the magnetic-abrasive powder so as to move the magnetic-abrasive powder relative to the surface of the part to be machined.
Claim 10
Dependent Claim
35 words
A device as defined in claim 7, wherein said means for supplying a magnetic-abrasive powder is formed so that the fluid jet presses the magnetic-abrasive powder to the surface of the part to be machined.
Claim 11
Dependent Claim
36 words
A device as defined in claim 7, wherein said means for supplying a magnetic-abrasive powder is formed so that the fluid jet displaces the magnetic-abrasive powder relative to the surface of the part to be machined.
Claim 12
Dependent Claim
36 words
A device as defined in claim 9, wherein said means for supplying a fluid jet is formed so that the fluid jet rotates the magnetic-abrasive powder relative to the surface of the part to be machined.
Claim 13
Dependent Claim
54 words
A device as defined in claim 7, wherein said means for supplying a fluid jet is formed so that the fluid jet presses the magnetic-abrasive powder to the surface of the part to be machined and at the same time displaces the magnetic-abrasive powder relative to the surface of the part to be machined.
Claim 14
Dependent Claim
58 words
A device as defined in claim 7, wherein said means for supplying a fluid jet includes means for accommodating the magnetic-abrasive powder in a temporary receptacle and attaching the temporary receptacle to said means for generating a magnetic field, so that thereafter the magnetic-abrasive powder leaves the receptacle to be supplied to the surface of the part machined.
