Detection of peripheral lines in CNC machine tools
The maintenance of CNC machine tools, like other maintenance work, needs to be rigorous and meticulous: to find out the commonality of the microcomputer numerical control system in terms of structure and working principle, and to locate the fault source in stages. Summarize scientific and reasonable fault analysis ideas, the key of which is diagnosis and testing, including the detection of peripheral lines, and strive to locate faults on the board line, and finally locate the fault at the element and device level. The preliminary analysis of the fault is based on the occurrence of the fault phenomenon to determine whether the fault is a general machine tool alarm (operation error, programming error, workbench movement overtravel error, etc.), or reproduce the fault, including various conditions of the machine that cannot be satisfied. (such as insufficient compressed air pressure, insufficient hydraulic system pressure, unstable voltage or high grounding resistance, etc.) are all such faults. Usually there are the following methods: first outside and then inside, first after the machine. Because CNC machine tools are advanced machining equipment with large technical complexity. After the machine is powered, the machine is first checked. The general mechanical fault is relatively intuitive and easy to find. See if the operation is normal, whether the stroke switch is inflexible, pneumatic or hydraulic, or not. If the machine is operating normally, check the electrical aspects. Of course, such checks include power supply voltage, various functional modules, test of parameter setting values, self-diagnosis alarm system prompts, and signal testing between functional modules.

As in welding, you must use the proper size cutting tip if quality work is to be done. The preheat flames must furnish just the right amount of heat, and the oxygen jet orifice must deliver the correct amount of oxygen at just the right pressure and velocity to produce a clean cut. All of this must be done with a minimum consumption of oxygen and fuel gases. Careless workers and workers not acquainted with the correct procedures waste both oxygen and fuel gas.
Each manufacturer makes many different types of cutting tips. Although the orifice arrangements and the tips are much the same among the manufacturers, the part of the tip that fits into the torch head often differs in design.
Because of these differences, there is the possibility of having two or three different types of Cutting Torches in your kits. Make sure that the cutting tips match the cutting attachment and ensure that the cutting attachment matches the torch body. Figure 4-13 shows the different styles of tips, their orifice arrangements and their uses. The tips and sears are designed to produce an even flow of gas and to keep themselves as cool as possible. The seats must produce leakproof joints. If the joints leak, the preheat gases could mix with the cutting oxygen or escape to the atmosphere, resulting in poor cuts or the possibility of flashbacks.
