2. After the two sides are finished, the shape is not milled, and the workpiece and the edge material are connected as a whole. The purpose is to facilitate the processing of the position of the column, the round hole and the oil port on the side.
3, CNC machining short-term columns and round holes; first leveling the workpiece with a dial gauge to level; then check whether the workpiece is horizontal, milling a "ten" frame at the top of the edge material, deep 0.5MM length and width Evenly divide; determine that it is horizontal and can be processed.
4. The spark machine processes the long hole and the column. Because the length of the workpiece exceeds 500, the Z value of the CNC is not enough.
5. The inner surface of the oil machine mouth of the spark machine (because the structure of the inner surface of the oil port is small and the precision is high, it is difficult to process on the CNC machine). Use the ABS board to make the two paving slabs to clamp the frame of the workpiece and when horizontally placed, the hole of the oil port on the workpiece is vertical, in order to facilitate the machining of the inner surface of the oil port.
6. The outer surface of the CNC machine oil port is fixed with the front two-plate aid plate. The direction of the oil port is perpendicular to the machine tool. The first step is to check whether the workpiece is level or not. The top surface correction; the second step can check whether the inner surface of the oil port is consistent after positioning. The method is to raise the height of 1MM on the top surface of the oil port and follow the circular hole punched out by the spark machine to see if it can be connected. Be sure to level the calibration before processing.
