Is it not difficult to CNC Machining? Teach you 6 steps to p

          No matter what you do, you want to become a master, must withstand the test of time, itself to continuously improve the ability to work, in the CNC processing industry, to become a master of CNC (metal cutting), graduated from university into the factory, at least 6 years. He should have both the theoretical level of the engineer and the practical experience and practical ability of the technician. Today, Rong Guansen technology is sharing with you: it is not difficult to learn CNC well. The master teaches you six steps to CNC NC machine programming.
      The first step: it must be an excellent technician without the support and trust of the staff. It is impossible to be an excellent craftsmen. Through such a long time of learning and accumulation, you should meet the following technical standards and requirements: 1, familiar with the structure and process characteristics of drilling, milling, boring, grinding and planing. 2, familiarity with the properties of processed materials. 3, solid tool theory basic knowledge, master cutting tool's conventional cutting amount and so on. 4. Familiar with the technical specifications and standards of the enterprise, the general requirements for the processing of various processes, and the process route of the conventional parts. Reasonable material consumption and time quota and so on. 5, collect a certain amount of tool, machine tool, mechanical standard data. In particular, we should be familiar with the tool system used in CNC machine tools. 6. Be familiar with the selection and maintenance of the coolant. 7, there should be a common sense of the related work. For example, casting, electrical processing, heat treatment and so on. 8. There is a good foundation for the fixture. 9. Understand the assembly requirements and requirements of the processed parts. 10. There is a good basis for the measurement technology.
       The second step: proficient in numerical control programming and the application of computer software. In practice, the standard of a good program is: 1, easy to understand, organized, the operator can understand. 2. The fewer instructions in a program section, the better, the purpose of which is simple, practical and reliable. From the programming point of view of the instruction, I think the instructions are also G00 and G01, and the others are auxiliary instructions, which are convenient for programming. 3. It is convenient to adjust. When the machining precision of parts needs to be trimming, the procedure is not changed. For example, the cutting tool is worn and needs to be adjusted, as long as the length and radius of the tool offset table are changed. 4. It is convenient to operate. The programming should be compiled according to the operating characteristics of the machine tool, which is beneficial to the observation, inspection, measurement, safety and so on. For example, the same parts, the same processing content, in vertical processing, and horizontal processing, processing, the program is certainly different. In mechanical processing, the simplest method is the method. As long as there are practical experience, you must agree with this sentence.
 
      The third step: the ability to operate the CNC machine tool skillfully. It takes 1-2 years to study, and the operation is about the feeling of hand, the beginner, especially the college students, understand how to do it, but the hand is not to listen. In the process to learn: system operation, fixture installation, datum centering and tool setting, set the zero bias set, tool length compensation, radius compensation, loading and unloading of tool and toolholder, measuring tool grinding, parts (skilled use of vernier caliper, micrometer, dial indicator the diameter, dial gauge, lever table) etc.. The best expression of the operation level is: horizontal processing, and large Longmen (dynamic sorghum, top beam) processing. The operation practice of the need for understanding! Sometimes I really have a "leisurely heart, beauty difficult to say with you" the mood in the NC workshop! You down to practice it! In general, qualified from the first parts processing to the processing precision of this process is the requirement of NC programming technology. Since the completion of the pro. You can't operate machine tools skillfully, this is not a pass.
       The fourth step: it is necessary to have a good base of fixture and fixture and the level of measuring technology. The difficulty of the reason analysis of the fixture is that it can only be qualitative, and it is difficult to quantify. If there is no experience in the design of the fixture and the clamping of the parts, it is very difficult. In this respect, it is suggested to ask for the precision coordinate boring machine and the technicians. One of the basic level of measurement precision when engaged in machining, to be able to skillfully use vernier caliper, micrometer, dial indicator, dial gauge, caliper diameter lever table, etc.. Sometimes the parts are processed, and the three coordinate measuring instrument is not expected.
      The fifth step: familiar with CNC machine tools. Well versed in the maintenance of CNC machine tools. The so-called familiar with CNC machine tools, should be done: 1, familiar with the numerical control electrical components and control principle. The name and function of each element in the electric box can be said and the electrical schematic diagram can be understood. The alarm content can be found out according to the electrical alarm number. 2. Understand the structure and transmission principle of the ball screw. It is clear which factors have a great influence on the accuracy of machine tools. 3. To understand the structure of the bearings at the two ends of the machine tool and its influence on the precision of the machine tool. 4, understand the lubrication system of the machine tool (bearing, spindle, every movement pair, gear box, etc.), and clear the distribution of each lubricating point. The grade of the lubricating oil of the machine tool and the normal consumption of oil per week or month. 5, understand the cooling system of machine tools: cutting (water and gas) cooling, spindle cooling, electric box cooling and so on. 6, understand the main drive structure of machine tools, the data characteristics of each machine speed and torque. 7, understand the characteristics of machine tool guide rail: line rail or slide rail, rigid (bearing capacity)? 8, it can exclude common operational faults (such as super limit, tool magazine error, etc.) 9, proficient in the accuracy of machine tools (static, dynamic) indicators and testing methods. 10. Familiar with the mechanism of knife base and the principle of changing the knife. The above few more than 3 years of time exercise, I am afraid it is very difficult to meet the requirements. And many enterprises do not have the conditions to learn. It is recommended to consult the master of the equipment maintenance department.
The six step: cultivate good habits, adapt to the characteristics of CNC machining. Plusminusthree Industrial Co., Ltd. was founded in 2010, professional R & D, manufacturing and sales of various types of precision thimble, thimble connector and precision metal lathe parts products. Our company has 12 CNC CNC machines, 6 automata, 10 processors, 3 POGO PIN automatic assembly machines, and can process all kinds of precision aluminum parts, copper parts, stainless steel parts, iron and titanium parts. We can also design and produce various products according to customer requirements.
