In the CNC machining industry, if you want to become a CNC master (metal cutting), it takes at least 6 years to graduate from university and enter the factory. He must have the theoretical level of an engineer, as well as the practical experience and hands-on ability of a technician, so he can get started in a short time as soon as possible, and learn the following six steps to get started easily.
The first step: must be an excellent craftsman. Without the support and trust of employees, it is impossible to become an excellent craftsman. Through such a long time of study 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 machines; 2. Familiar with the performance of processing materials. 3. Solid basic knowledge of tool theory, master the conventional cutting amount of the tool, etc. 4. Familiar with the company's process specifications, guidelines, general requirements that can be achieved by various process processing, and process routes of conventional parts. Reasonable material consumption and working hours quota, etc. 5. Collect a certain amount of data on tools, machine tools, and mechanical standards. Particularly, you must be familiar with the tool system used in CNC machine tools. 6. Familiar with the selection and maintenance of coolant. 7. Have a common sense understanding of related types of work. For example: casting, electrical processing, heat treatment, etc. 8. Have a good fixture foundation. 9. Understand the assembly requirements and use requirements of the processed parts. 10. Have a good foundation of measurement technology.

Step 2: Proficient in the application of CNC programming and computer software. In practice, the criteria for a good program are: 1. It is easy to understand, organized, and everyone can understand it. 2. The fewer instructions in a block, the better, for the purpose of being simple, practical and reliable. From the perspective of programming, I think the commands are also G00 and G01, and the others are auxiliary commands, which are set to facilitate programming. 3. Convenient adjustment. When the machining accuracy of the parts needs to be fine-tuned, there is no need to change the program. For example, if the tool is worn out, if you want to adjust it, just change the length and radius in the tool offset table. 4. Convenient operation. The programming should be compiled according to the operating characteristics of the machine tool, which is conducive to observation, inspection, measurement, safety and so on. For example, the same kind of part, the same processing content, in vertical processing, and horizontal processing, processing separately, the procedure is definitely different. In mechanical processing, the simplest method is the method. As long as you have practical experience, you will definitely agree with this sentence!

The third step: be able to operate CNC machine tools proficiently. This requires 1-2 years of learning, and the operation is very handy. Beginners, especially college students, know how to do it in their hearts, but they just don’t listen. In this process, you must learn: system operation mode, fixture installation, part datum alignment, tool setting, zero offset setting, tool length compensation setting, radius compensation, loading and unloading of the tool and tool holder, and the cutting edge of the tool Grinding, measurement of parts (proficient in the use of vernier calipers, micrometer cards, dial indicators, dial indicators, inner diameter lever indicators), etc. What can best reflect the level of operation is: horizontal processing, and large gantry (moving beam, top beam) processing. The practice of operation requires savvy! Sometimes there is an artistic conception of "a leisurely mind, but it is difficult to talk to you"! In the CNC workshop, you can calm down and practice! Generally speaking, from the processing of the first part to the processing accuracy The qualification process requires the CNC programming technician to complete it in person. You can't operate the machine proficiently, you can't pass this level.

The fourth step: Must have a good tooling and fixture foundation and measurement technology level. The difficulty in analyzing the cause of the fixture is that it can only be qualitative but difficult to quantify. If there is no experience in fixture design and part clamping, the difficulty will be great. For learning in this area, it is recommended to consult the technicians who do precision jig boring machines. One of the basic skills of machining to accurately measure the level is to be able to use vernier calipers, micrometers, dial indicators, dial indicators, inner diameter lever meters, calipers, etc. proficiently. Sometimes parts processing, three-coordinate measuring machine can not be counted on.

Step 5: Familiarize yourself with CNC machine tools. Proficient in the maintenance of CNC machine tools. The so-called familiarity with CNC machine tools should: 1. Be familiar with CNC electrical components and control principles. Can tell the name and function of each component in the electrical box, and understand the electrical schematic diagram. The alarm content can be found based on the electrical alarm number. 2. Understand the structure and transmission principle of the ball screw. Know which factors have a greater impact on the accuracy of the machine tool. 3. Understand the structure of the bearings at both ends of the machine tool screw and its influence on the accuracy of the machine tool. 4. Understand the lubrication system of the machine tool (bearings, main shafts, motion pairs, gearboxes, etc.), and know the distribution of lubrication points. The brand of machine lubricating oil and the normal consumption of oil every week or month. 5. Understand the cooling system of the machine tool: cutting (water, air) cooling, spindle cooling, electric box cooling, etc. 6. Understand the main transmission structure of the machine tool, and the specific data characteristics between the speed and torque of each machine tool. 7. Understand the characteristics of the machine tool guide rail pair: Is it a linear rail or a sliding rail, and how rigid (carrying capacity) is? 8. Can eliminate common operating faults (such as: exceeding the limit, tool magazine tool number error, etc.) 9. Proficient in various accuracy of the machine tool (Static, dynamic) indicators and detection methods. 10. Familiar with the tool magazine mechanism and the principle of tool change. For the above items, it is difficult to meet the requirements without exercise for more than 3 years. And many companies do not yet have the conditions to learn. It is recommended to consult the master of the equipment maintenance department.

Step 6: Develop good habits and adapt to the characteristics of CNC machining. Shenzhen Rongguansen Technology Co., Ltd. was established in 2010 to specialize in R&D, manufacturing and sales of various precision thimble, thimble connector and precision metal lathe products. Our company has 12 CNC machines, 6 automatic machines, 10 processing machines, and 3 POGO PIN automatic assembly machines, which can process various precision aluminum, copper, stainless steel, iron, and titanium parts... ...We can also design and produce various products according to customer requirements.
