FCX metal CNC punching operation process

Under normal circumstances, CNC punching to a processing method of using drills on the FCX metal Industrial Sheet Metal Parts/Chassis or Sheet Metal Enclosures/Cabinets/Housing/Casing/Boxes indication. Generally speaking, when drilling the product is drilling on the drilling machine, the drill head should be completed in two movements:
① The main movement, that is, the rotation movement of the drill head around the axis (cutting movement);
② Secondary exercise, that is, the drill head moves in the straight line of the workpiece along the axis.
When drilling, because there are disadvantages in the drill structure, marks will be left for the place where the product processing is processing, affecting the quality of the workpiece processing, and the processing accuracy is generally below IT10. The surface roughness is about RA12.5 μm. Essence

FCX metal CNC punching operation process:
1. Line: Before drilling, the first understanding of the graphic requirements. According to the basic standard requirements of the drill, the central line must be used to draw the center line of the hole. Use a gazed caliper or steel sheet to measure.
2. Check the checked square or inspecting circle: After the line is completed and checks the qualification, the checked square or inspection circle with the center line of the hole asymmetry should be drawn. And correct the diamond position.
3. Sample: Drive the corresponding check -ups or check the circle carefully. Pick a small point first, measure multiple times in different directions of the cross center line. See if the eyes are indeed on the cross point of the cross center line, and then the samples are rushing, round, and big The knife is determined.
4. Placed: Wipe the packets, fixture surfaces, and workpiece reference planes with rags, and then clamp the workpiece, and the clamping is flat and reliable as required, and it is convenient to query and measure at any time. Pay attention to the method of installing the workpiece to prevent the workpiece from deformed due to the fixture.
5. Test drill: Before the official drilling, you must test the drill: the drilling head horizontal blade is aimed at a shallow pit with an eye -like drill, and then inspect whether the position of the shallow pit is correct. Coaxial axis. If you violate the smaller, you can force the workpiece to move in the opposite direction in the opposite direction of the drilling, and reach the gradual pair.
6. Drilling: The drilling of the machine is generally manual in the operation. When the positioning of the diamond pore is required, the drilling can be performed. When manually entering, the strength of the feed should not cause the drill bit to bend and avoid skew the hole axis.
