Abstract
A milling system to be used in the manufacturing of electronic card for chamfering the edge of a card (e.g. a SIMM card) to facilitate its insertion in a socket on a board. According to a preferred embodiment of the present invention, the card to be chamfered (e.g. a SIMM card) is linearly moved within a milling system including two motor mills. The two mills are inclined with respect to each other forming an angle of about 90°. The card passes through the apex of this angle. The mills are mounted on a bracket system having a guide which guarantees the correct positioning of the milling system with respect to the card edge.
Claims10
A milling system for chamfering an edge of an electronic card, the system comprising:
- milling means for milling said card edge, the milling means including at least one couple of juxtaposed rotating mills, each mill having an axis of rotation forming an acute angle with the plane on which the card lies;
- movable guide means for relatively positioning the milling means and the card, including a follower to contact the card edge during the chamfering operation to follow the card edge, wherein the follower includes at least one rotational disc having a v-shaped rim, the guide means being coupled to said milling means;
- and
- moving means for relatively moving the card and the milling means, the card passing through said at least one couple of mills.
