Table-top type key-seater

摘要: The present invention provides a cheap machine of small size exclusively used for processing key groove, requiring no skillfulness. It is so constructed that a voltage applied to an insulated work table through lead wires. A piece be processed reciprocated in left- and rightward directions. center position of is calculated, based on digital displays conduction signal positions, which left and right contact positions a cutting tool inserted into throughhole, air inner wall of the groove should formed, with wall and set cutting by means scale, fixed by using an eccentric lever. moved automatically intermittently pitch set, linked air cylinder. distance a separation s between two magnetic sensors and cutting K having depth d effected by moving intermittently backward region, at two extremities respond, respectively, magnet base, formed one body with table.
