Patent ID: 7056429

Claim:
Method for deburring and rounding a side face of a thin-sheet and annular metal ring element ( 1 ) of a push belt for a continuously variable transmission, comprising: an electrochemical machining step that receives a thin-sheet and annular metal ring element ( 1 ) of a push belt for continuously variable transmission in a device ( 10 ) for electrochemical machining of the ring element ( 1 ), an annular electrode ( 5 , 20 ) being positioned in the device ( 10 ) i) opposite an axially oriented annular side face ( 3 ) of the ring element ( 1 ) along an entire circumference thereof, and ii) at the same time, located in such close proximity distance relative to the side face of the ring element that deburring and a rounding-off of said side face ( 3 ) takes place during the electrochemical machining, which electrode ( 5 , 20 ), as seen in a thickness or radial direction of the ring element ( 24 , has a dimension (B) which is at least twice as great as a dimension (D) of the ring element ( 1 ) in the thickness direction.
