<p>The guide installation is for a spark erosion tool holder on a flat enclosed path eccentric in relation to a component fixed to the machine. A cylinder bush (10), vertical to the plane of the path, is linearly displaceable. The bush (10) is rotatably located around the machine centre vertical line (11), and has a hole (12) inclined against that vertical line (11). In the hole (12) is an inclined bolt (13) displaceable along its lengthways axis which projects at one end, to which the tool is fitted. The bolt is located in a ball guide bush inside the cylinder bush and with its end projecting from the hole. A pin (15) has its lower part rotatably fitted in a cross slot.</p> |
