Teach you six steps to play with CNC machine tools.

The first step: you should achieve to meet the following information technology development level and requirements.

1. familiar with the structure, process technology characteristics of drilling, milling, boring, grinding and planing machines.

2. familiar with the characteristics of processing materials.

3. solid knowledge of the basic education of tools for theoretical research, mastering the conventional cutting dosage of tools, etc.

4. familiar with the process card payment providers specifications and guidelines of the enterprise, the general requirements that can be achieved by various process processing, and the process route of conventional parts. Reasonable material consumption, work hour quotas, etc.

5. Collect a certain amount of information about cutting tools, machine tools and mechanical standards. In particular, be familiar with the CNC machine tool system.

6. Familiar with the selection and maintenance of coolant.

7. Must have a common sense understanding of the relevant technical trades. For example: casting, electrical processing, heat treatment, etc.

8. Good foundation in fixtures.

9. Understand the assembly requirements and usage requirements of machined parts.

10. A good foundation in measurement technology.

The second step: proficient cnc milling servicein Chinese CNC system programming and computer network software application. In practice, the criteria for a good program are

1. easy to understand, organize and comprehend by all operators.

2. The fewer instructions in the program the better, this is for simplicity, practicality and reliability. From the point of view of programming instructions, I think the instructions are also g00 and g01, the others are auxiliary instructions, which are set up for the convenience of programming.

3. Easy to adjust. When the machining accuracy of a part needs to be fine-tuned, there is no need to change the program. For example, if the tool is worn and it is to be adjusted, only the length and radius in the tool offset table need to be changed.

4. Easy to carry out the operation. Program design s17+ antminerand preparation of enterprises to be based on the operating characteristics of different machine tools to compile, conducive to student observation, inspection, measurement, safety, etc.. For example, the same part, the same processing research content, in vertical machining, and horizontal machining, respectively, through the processing, the program can certainly also be different.

The third step: skilled operation of CNC machine tools. Operation is about the feeling of the hand, beginners, especially college students, the heart knows how to do, but the hand is not to listen to the command. In this process, we have to learn how the system works, the installation of fixtures, the alignment of the part datum, tool setting, zero point offset, tool length compensation, radius compensation, tool and shank installation and uninstallation, cutting tool grinding, measurement of the part (skilled use of vernier calipers, micrometers, micrometers, percent tables, internal diameter lever tables) etc.). The level of operation is best demonstrated by: horizontal machining, large gantry (moving beam, top beam) machining. Operation practice needs to be smart! Sometimes there is really a "leisurely heart must, the beauty of the unspeakable" mood! In the CNC shop, you just have to calm down and practice! Generally speaking, the process from machining the first part to machining accuracy needs to be done by the CNC programming technician himself. If you can't operate the machine proficiently, you won't get through it.

Step 4: Have a good level of fixture foundation and measurement skills. The difficulty of fixture cause analysis is qualitative and difficult to quantify. If it is fixture design, the clamping experience of the parts, then it is much more difficult. In this area of study, it is recommended to do precision coordinate boring machine, technical staff for advice. One of the basic skills of machining is to be able to use vernier calipers, micrometers, percentages, micrometers, inside diameter lever meter, calipers, etc. Sometimes parts are machined and coordinate measuring instruments are not expected.

Step 5:Familiar with CNC machine tools. Proficient in the maintenance of CNC machine tools. To be familiar with CNC machine tools, you should:

1, familiar with the CNC system electrical equipment components and control working principle. Be able to say the name and role of each different component in the electrical box, and be able to read the electrical schematic diagram. Be able to find out the content of the alarm information according to the enterprise electrical alarm number.

Understand the structure and transmission principle of ball screw. The factors that affect the accuracy of the machine tool are obvious.

3. Understand the structure of the screw bearing and its effect on the accuracy of the machine tool.

4. Know the lubrication system of the machine tool (bearing, spindle, motion sub, gear box, etc.). And know the distribution of lubrication points. Machine tool lubricant brands and the normal weekly or monthly oil consumption.

5. Understand the cooling technology system of Chinese machine tools: cutting (water, air) cooling, spindle cooling, electric box cooling, etc.

6. to understand the main transmission structure of machine tools and the specific data characteristics between the speed and torque of each machine tool.

7. Understand the Chinese machine tool through the guide rail sub-characteristics: is it a line rail or two slide rails, rigidity (load management capacity) how?

8. Can troubleshoot common operating faults (such as over-limit, tool magazine tool number error, etc.)

9. proficient in the work accuracy (static, dynamic) indicators and testing technology methods of Chinese machine tools

10. Familiar with tool magazine mechanism and tool change principle.
