Basic machining process of aluminum alloy aluminum cover is briefly introduced.

1 programming
. after processing the positive and negative surface, milling shape, let the workpiece and scrap are connected into a whole, the purpose 

is convenient post processing on the side of the hole and the oil outlet position.
3. CNC machining in the short direction columns and a circular hole; first school of positioning the workpiece with a dial indicator to leveling; i

nspection work level, on the rim of the top of milling a "ten" word, deep 0.5mm length to width uniform split; determine the level before processing.
4 EDM machine for the long direction of the hole and the column, due to the length of the workpiece more than 500, while the Z of the CNC value

 of the trip is not enough 500.
5 the inner surface of the engine oil, (because the structure of the inner surface of the engine oil is small, the precision is high, and it is difficult to

 process the CNC machine). Use ABS board to do the two piece of the board to clamp the workpiece and the horizontal position can make the oil hole 

on the workpiece is the vertical state, the purpose is to facilitate the machining of the inner surface of the engine oil.
6. CNC machining oil port of the outer surface, in front of the second shop help plate fixation of the workpiece and oil export and the direction of the

 machine is vertical, the first step first test workpiece is level, with the dial gauge in oil export position of the top surface of the correction; after the

 second step and localization testing whether the same oil mouth surfaces are consistent, the method is at the mouth of the oil the top surface elevation

 1mm in spark machine play out the hole shape, and see if you can pick up on. Must be leveling school Affirmative processing.
