Electroerosion machine with a frame with a new structure

摘要

EDM machine for machining of a stationary workpiece including a device for moving the machining head of the machine and hence the tool along the Z axis and a cross movements system with two chariots each sliding along one of the reference axes X and Y of the machine for moving the machining head along these axes. A main frame body is shaped as a cube having four vertical walls joined together so as to delimit a square space all these walls being immovably attached to the same base forming the lower face of the cube and to the horizontal element with an opening cut out in it forming the upper face of the cube. An assembly designed to move the machining head along the Z axis along at least one of the chariots of the system in the X-axis and/or Y-axis of cross movements is mounted above the upper face of the cube thus resting on four pillars formed by the edges of the cube delimited by the four vertical walls. The opening cut out in the upper face of the cube being suitably profiled to allow this assembly to move freely along at least either the X or Y axis. The machining tank and the work table are mounted atop a vertically actuable column extending from a base of the body during machining.
