Precautions for slow wire processing

shower

1. Read the drawing requirements. What material, how high.

2. Call out the program to simulate the graphics, compare it with the drawing to see if it is correct, so as not to copy the wrong program, and then zoom in on the graphics to see if there are prongs.

3. Self-measurement is required after processing. When machining larger punches, an extra knife should be added. First, use a larger correction amount than the first knife to open the roughing. After roughing, use the first knife to make the first knife smaller. The speed should be faster and the water pressure should be small. The amount of correction is also smaller than the usual first cut to prevent deformation.

into the block

1. There are splint into the block, take-off plate into the block, and lower template into the block. Before processing, see what the drawing is into the block.

2. It is relatively simple to insert the splint into the block, and the corners can be cleaned. The inner hole must be processed first, and the punch should be used to match it, and then the sliding match is enough.

3. The removal of the plate into the block is similar to that of the splint into the block, the inner hole should be slightly tighter, and the fit should be tight and slippery.

4. The lower template generally has a knife edge. It is necessary to see the requirements of the drawing, how many knife edges and how many inclinations. The lower module can not clear the corners of the block. Before processing, it is necessary to zoom in on the simulated graphics on the machine.

5. Before processing into the block, before there is no frame mold, it is necessary to make a comparison drawing to see if there are any leaks and holes, and whether the holes are penetrated. If there are many holes and relatively small holes, sweep the edges when punching, sweep the same side when framing, or sweep two holes on the same straight line when framing. When setting the coordinates, the small hole shall prevail.

6. The inner hole must be machined first before inserting the block, and then it can be cut off after matching with a punch or a plug gauge. The larger entering block should be roughened, and then the inner hole should be processed. After the inner hole is processed, the shape should be repaired and cut off to prevent deformation. .

7. When machining a particularly large block, it is necessary to use a larger correction amount than the first knife to open the rough shape first. After the inner hole is processed, the roughing correction amount is smaller than that of the usual first knife. The conditions are also weaker than the usual first knife, the speed is faster, and the water pressure is also small to prevent deformation.

8. When processing small holes, pay attention to whether there will be two or more small scraps, otherwise the machine head will be stuck.
