In the field of machining industry, the precision size control of drawings plays a vital role, which directly affects the assembly performance and quality of mechanical equipment. The main factor affecting the size of precision machining is the error problem, because the error problem is affected by a variety of factors, in the machine precision machining will inevitably appear a variety of error problems, so only the use of various technical measures, the precision control in a scientific range.

Understand the content of machining
In the field of mechanical processing in China, there is a clear definition of the accuracy of mechanical processing, which refers to the professional and technical personnel after the completion of the processing of mechanical parts, the use of instruments to detect the position of the parts, shape, size and related data, so as to determine the degree of compliance of the parts. Generally speaking, the main factor affecting the accuracy of machining is the various errors generated in machining, and the operators and technical units of technical processing must attach great importance to this problem. In machining, the control and grasp of precision are obviously related to the error problem of machining. Machining error is mainly reflected by the shape, size and position, it is through the use of mechanical size control to achieve the purpose of controlling the precision of machining, in ensuring the surface quality of machining, the machining size error control within a reasonable range. In the process of machining, due to the impact of the benchmark and the machining surface, it will cause the deviation of the position of the precision parts, so the verticality, position and parallelism of the precision machining must be strictly controlled.

/ Factors affecting precision machining accuracy
In the process of precision machining, there are strict requirements for various production technologies and production processes, so as to reduce or even eliminate the purpose of machining technology errors. In machining, the error between the spindle rotation is an important factor affecting the accuracy. In the process of modern mechanical production and processing, the error caused by the spindle rotation problem is very obvious, which is more obvious in high-tech and high-precision products, which is also an important factor affecting the processing. For the resulting error, the error can be reduced by processing and transforming the machinery. In addition, bearings with higher precision can also be used, which can also significantly reduce the resulting error.
In addition to the error caused by the spindle rotation, the error caused by the problem of the fixture and the tool can not be ignored. Due to the requirements of production, machining manufacturers will renovate the size, type and model of fixtures and tools to a certain extent, which will have a greater impact on the accuracy of machining. In the actual processing process, the size of the fixture and the tool are fixed, which makes it impossible to adjust the size of the fixture and the tool in the process of production and processing. This will cause a certain error flow in the mechanical processing when the technical parameters and the working environment change.
In addition, due to the process of using and installing fixtures and tools, the position of fixtures and tools will be changed, resulting in errors. Of course, the cutting force will also have a certain impact on the machining, resulting in the generation of errors, and ultimately the accuracy of the machining. Due to the influence of the external environment and temperature, the machined parts can easily affect the cutting force. The greater accuracy error is caused by the local change of the process system and the overall deformation. In the process of mechanical production and processing, if the change of the direction of the tightening degree and the insufficient stiffness of the parts are affected, the deformation of the machined parts will be caused, and the machining will produce a lot of errors, which will affect the precision control of the machining.
Technical measures to control machining accuracy
In the process of mechanical production and processing, the problem of processing accuracy must be strictly controlled, and the accuracy problem must be comprehensively considered, so the processing accuracy of each part must be greatly improved, so as to improve the accuracy of the entire mechanical equipment. In the process of machining, the original error plays an important role in ensuring the quality of machining. For mechanical components, it is necessary to classify them according to the requirements of relevant regulations, according to the material, type, model, size and use, and then develop a certain accuracy range, and control the precision error of the machined parts within this range. For the technical staff, it is necessary to determine a reasonable range of the error generated in the machining, and make reasonable adjustments to the fixture and the tool, so as to control the error within this reasonable range, and ultimately reduce the error of the part to the greatest extent. Only by controlling the errors in machining, can the precision control of machining be achieved to the maximum extent, so as to achieve the purpose of improving the precision of machining.
Compensating error method
Error compensation method refers to the use of processing means to achieve error compensation after the machining of mechanical parts, so as to achieve the purpose of reducing the error in the processing of parts. Compensation error method is a very important technical measure to solve the stiffness problem of the process. The main principle is to compensate the original error by creating a new error, so as to improve the precision control level in precision machining. Error compensation method is an important means to reduce the machining error, which has been widely used in practice at home and abroad. In domestic regulations, the original error is generally represented by a negative number, and the compensation error is specified as a positive number, so that when the original error and the compensation error are closer to zero, the smaller the machining error.
Of course, the methods of reducing errors and improving precision control are not only these two, but also the transfer error method is a more commonly used method of reducing errors. Therefore, in the actual production process, it is necessary to choose a reasonable method to reduce the error according to different situations, so as to achieve the best precision control and promote the continuous and stable development of precision machining.
Today, with the rapid development of social economy and industrial reform, the role played by precision machining has become more and more important, and China's machining industry has also made great progress, not only the quality has been greatly improved, but also greatly expanded in the scale of production. With the development of the industrialization process, the precision of precision machining is also more and more attention, therefore, it is necessary to strengthen the control of precision in the process of machining (precision machining process, the control of precision must be attached great importance, and take reasonable technical measures to solve the problems.

The importance of product processing technology
The process of the internal structure of the product is closely related to the processing cost. The processing technology used by the product directly determines the production cost, and the processing efficiency and production capacity will also be affected by it.
From the perspective of product design, if the manufacturing threshold of processing technology can be fundamentally reduced, on this basis, certain processing costs can be reduced, and the processing CT time of CNC machine tools can be shortened, and the processing quality and processing quality can be improved.

Tool life management control in CNC machining
The life management control of the tool by the CNC system is to calculate the number of tool machining, or to determine the processing time. Therefore, when the tool life reaches the expected number of machining times or time of the system, the CNC automatically stops the action. It is assumed that when manual supervision is not in place, or when the tool is not able to stop changing in the expected situation, the CNC machining process will be affected. Therefore, tool life is a key factor affecting CNC production capacity.
Especially when the CNC machining process of a workpiece is too much, the processing amount is cumbersome, and the dimensional accuracy of the processing is relatively strict, the tools to be used will be more. At this time, the CNC tool library automatically changes the tool, and the knife action is more frequent, and the tool wear is larger, so that the manual tool change and machine adjustment are more frequent.
Therefore, tool wear is an important indicator that affects the normal production rhythm and capacity of CNC. Through technical measures to improve the process, improve the overall life of the tool, not only can save the cost of the tool, but more importantly, can reduce the stopping time of the CNC spindle, so as to improve the efficiency of CNC processing, improve the production quality and capacity.

CNC machining abnormal problem elimination
The inspection work needs to be comprehensive, such as the use of the cylinder, solenoid valve, motor and other electrical parts in the oil environment on the equipment and fixture condition, and the investigation of these parts before the operation can effectively avoid the situation that the production of CNC spindle is forced to stop, so as to improve the utilization rate of the spindle.
Machine iteration is expensive, but there are other methods we can use to do it at a very small cost in exchange for a high yield.
The high-quality management of CNC machining production should be put in the first place, and the above six points can effectively improve the production performance and capacity of the machine tool.

The aerospace industry is worth an estimated $300 billion and shows no signs of slowing down. We usually think of aerospace as = airplanes, but there are also thousands of satellites and rockets that require thousands of precision parts.
The aerospace and defense industry relies on CNC machining to manufacture complex precision parts that leave no margin for error. The tight tolerances, rapid prototyping and scalability of CNC machines are ideally suited to meet the needs of this industry.
Construction industry
The construction industry needs reliable, high-strength parts that can operate in harsh environments. CNC machine tools can process large and small metal parts needed for construction equipment.
CNC machining is the best manufacturing method for difficult metal alloys. High-strength steel alloys are commonly used to make parts for cranes, lifting equipment, bulldozers and other construction equipment. Gears, pump equipment, and high-strength fasteners are just a few examples of NC machined parts.
Energy industry
The gas, oil and energy industry is another huge market that relies on many #CNC machined components. Precision valves, bushings and sensor devices all require precision machined parts.
To keep vital energy infrastructure operating at peak efficiency, components need to fit perfectly together.
Parts used in harsh environments require high precision and high corrosion and heat resistance. Salt water and chemicals can destroy many metal parts, so the industry needs metals such as Hastelloy, which often require modern CNC machine tool cutting tools.
In general, CNC machining process plays an irreplaceable role in modern manufacturing industry, and its high precision, high efficiency and flexibility bring great development opportunities and competitive advantages to all walks of life. With the continuous progress of technology and the continuous expansion of applications, CNC machining technology will continue to play an important role in the future manufacturing industry, and make new contributions to the progress and development of human society.#Honscn #cnc
