What should be paid attention to in CNC precision parts processing?

1. CNC lathe processors must read the content of the process card clearly before processing, clearly know the part, shape, and size of the drawings to be processed of the workpiece, and know the processing content of the next process.

2. Before the workpiece is clamped, it is necessary to measure whether the size of the blank meets the requirements of the drawing. When the workpiece is clamped, it must be carefully checked whether its placement is consistent with the programming operation instruction.

3. Self-inspection should be carried out in time after the rough machining is completed, so as to adjust the data with errors in time. The content of the self-inspection is mainly the position and size of the processing part.

(1) Whether the workpiece is loose;

(2) Whether the workpiece is correctly centered;

(3) Whether the size from the part processed by CNC hardware parts to the reference edge (reference point) meets the requirements of the drawing;

(4) The position size between the CNC machining parts. After checking the position size, measure the rough shape ruler (except the arc).

4. After rough machining and self-inspection, finish machining is carried out. After finishing, workers should conduct self-inspection on the shape and size of the processed part: check the basic length and width dimensions of the processed part on the vertical surface; measure the base point size marked on the drawing for the processed part on the inclined surface.

5. Workers complete the self-inspection of the workpiece and confirm that it meets the drawings and process requirements before removing the workpiece and sending it to the inspector for special inspection.
