First of all, the most important error of secondary positioning and non coincidence is the error of non coincidence. When machining the workpiece on the machine tool, it is necessary to select some geometric elements on the workpiece as the positioning datum during processing. If the selected positioning datum does not coincide with the planning datum, the datum misalignment error will occur. Measurement error: when measuring parts during or after processing, the measurement method, measuring tool precision, workpiece and subjective and objective factors directly affect the measurement accuracy. There are fixture errors and tool errors: mechanical fixture errors: the role of the fixture is to make the workpiece equivalent to the tool and machine tool with the correct orientation, so the geometric errors of the fixture have a great impact on the machining errors. Spindle rotation error refers to the variation of the actual rotation axis of the spindle relative to its uniform rotation axis at each moment, which will directly affect the accurate density of the workpiece. Any tool in the cutting process can not prevent wear, and thus cause the size and shape of the workpiece to change.

The structure and shape of machine parts are composed of some basic geometric surfaces. The machining process of machine parts is the process of obtaining these geometric surfaces. Different processing methods can be selected for the same surface, but the processing quality, processing time and cost obtained by each processing method are different. The task of engineering and technical personnel is to select the most appropriate processing method according to the specific processing conditions, so as to ensure that the machine parts meeting the requirements of the drawings can be processed. When selecting the processing method, the final processing method is always selected first according to the technical requirements of the main surface of the part and the specific conditions of the factory, and then the processing methods of the relevant previous processes of the surface are selected one by one. The machining surface of parts has certain processing requirements. Generally, it is impossible to achieve the requirements through one processing, but it can be achieved gradually through multiple processing (i.e. multiple processes).

Arrangement of heat treatment process and surface treatment process!

The heat treatment processes arranged to improve the cutting performance of workpiece materials, such as annealing, normalizing, quenching and tempering, should be carried out before cutting.

In order to eliminate the internal stress of the workpiece, the heat treatment process, such as artificial aging and annealing, should be arranged after the rough machining stage.

In order to improve the mechanical properties of workpiece materials, heat treatment processes, such as quenching, carburizing and quenching, are generally arranged between semi finishing and finishing.

In order to improve the wear resistance and corrosion resistance of the workpiece surface, the heat treatment process arranged for the purpose of decoration, such as chromium plating, zinc plating, blue plating, etc., are generally arranged in the final stage of the process.

The processing of metal equipment is not only the quality required by customers, but also the needs of the times. Why do you say that? The general quality is not guaranteed. Do you think that anyone else will buy your products? In the long run, your manufacturers will lose money. If we continue to develop in this way, we will not even get the cost. Therefore, it is Zui to guarantee the customer’s return purchase rate in the early stage of hardware processing important.

How about the hardware processing market

Since entering the 21st century, China is gradually becoming an international hardware processing and exporting country, with huge market and consumption potential. China’s self-developed various kinds of daily hardware products rank in the forefront of the world, and have achieved good economic benefits and reputation. The development of hardware processing market has thousands of years of history, with the continuous evolution of society, its development is also changing with each passing day. All kinds of advanced products are inseparable from the design and development of hardware, and these just confirm the changes of social development.

How about the hardware processing market

With the deepening of competition, the profit space of metal stamping industry chain in each stage is compressed, and the space of price reduction is decreasing day by day. More and more enterprises realize that only relying on price competition can not establish the core competitiveness and is not the direction of long-term development, so they try to explore a new development path. Many hardware enterprises have increased their investment in technology, developed new products with high-tech content, took product differentiation as a long-term plan for enterprise development, sought new market demand, established new economic growth point, and realized sustainable development of enterprises. The next few years will be a period of high-speed shock in the metal stamping industry. The direct consequence of this high-speed shock is the expansion of the polarization trend of the current metal stamping industry. It is expected that in the next few years, there are not so many metal stamping enterprises that can survive in the market. But the high-speed shock of the metal stamping industry will bring great opportunities, and the result of the shock will make the market operation more rational.

Metal parts processing, most of the use of mechanical equipment to complete the work, the effect is good, and the processing speed is fast, in a certain range involved is also relatively wide, the era is changing, we need to apply the mechanical equipment is also increasing, different industries, then the types of mechanical equipment, or classification, model are different, precisely because with the times Change, machining precision, requirements are higher and higher. So we must pay attention to the craftsmanship! What are the skills of turning simple shaft in machining knowledge?

Mechanical processing, Dongguan machining skills have what

What is the axial datum in machining knowledge?

Compared with shaft, the expression scheme of sleeve is roughly the same as that of shaft. Generally, only one basic view and a small number of auxiliary views are needed. Only because the sleeve is hollow structure, it is necessary to carry out sectional representation (whether to use full section, half section or partial section depends on the complexity of the internal and external structure shape of the part). The dimension datum only has radial datum and axial datum. The axial datum should be the axial positioning surface when the sleeve is fitted to other parts, that is, the right end face of the left-hand 040 cylinder. The surface roughness requirement is such as the ring plane with Gen value of 0.8.

What is the method of threading in machining common sense?

If the diameter of the round rod is too large, it is difficult to insert the die and the thread is not complete if it is too small. The diameter of round rod can be calculated by consulting the manual or empirical formula: the diameter of round rod is 4 = (nominal diameter of thread) – 0.13p (pitch). The end of round rod with thread set shall be chamfered (15 ° ~ 20 °), and the diameter of small end of round rod after chamfering shall be less than the minor diameter of thread, so as to facilitate thread setting. The process of threading is similar to tapping. When threading, the die end face should be strictly vertical to the round rod. When starting to rotate the die, a little pressure should be evenly applied; after 3-4 turns of threading, the die can only be rotated without pressure. In the process of thread setting, it is necessary to reverse frequently for chip breaking. The thread of steel parts should be lubricated with oil.

Metal parts, parts processing, is now very common, mainly related to our development, the better, the faster the development, the more research and development of mechanical equipment, the effect is better, the role is obvious, automation era, hardware accessories in a wide range, market development in recent years, however, hardware processing need to pay attention to the details Many, for example?

Dongguan Hardware processing, Dongguan Hardware processing effect is how

1. The designed stamping parts must meet the product use and technical performance, and be easy to assemble and repair.
2. The designed stamping parts must be conducive to improving the utilization rate of metal materials, reducing the varieties and specifications of materials, and reducing the consumption of materials as far as possible. If allowed, low-cost materials should be used to make the parts as much as possible to achieve no waste and less waste blanking.
3. The designed stamping parts must be simple in shape and reasonable in structure, so as to simplify the die structure and simplify the number of working procedures. In other words, the least and simplest stamping process is used to complete the processing of the whole part, reduce the use of other processing methods, and facilitate the stamping operation, facilitate the organization of mechanized and automatic production, and improve labor productivity.
4. Under the condition of ensuring normal use, the stamping parts designed should have lower requirements for dimensional accuracy and surface roughness, and be conducive to product exchange, reduce waste products and ensure product quality stability.
5. The design of stamping parts should be conducive to the use of existing equipment, process equipment and process flow to process them, and to extend the service life of the die.

Our staff, in the production of anything, we should pay attention to whether its quality is up to the standard. We need to achieve some specified indicators. Tangxia precision hardware processing is the same. What are the five evaluation indicators of precision hardware processing quality?

1. Surface texture morphology: including surface waviness and surface texture direction in surface roughness,
2. Surface defects: including machining burr, flash, macro crack, surface tear and wrinkle.
3. Microstructure, surface metallurgy and chemical properties. It includes metallographic structure, micro crack and surface chemical properties.
4. Surface mechanical properties: including the degree and depth of work hardening, the size, direction and distribution of residual stress.

For our technicians, it’s very good for us to be familiar with various safety precautions, which can prevent and reduce the problems in this respect. The same is true for machining. What are the safety precautions in Dongguan machining?

(1) Easy to operate, reduce walking back and forth, avoid unnecessary bending, tiptoe action.

(2) The positioning is accurate and reliable, so as to prevent misoperation caused by slight vibration.

(3) The movement direction of the operating parts of the machine tool and the moving direction of the operated parts shall meet the requirements, and there shall be simple symbols.

(4) The necessary interlock mechanism shall be installed to prevent the uncoordinated action of the operating parts and the accidents caused by the uncoordinated operation of many people.

(5) The structure and arrangement position of handle, hand wheel and button shall meet the requirements. The start button shall be installed in the casing or with a guard ring to prevent accidental touch. The hand wheel and handle installed on the shaft rod will rotate along with the shaft to hurt people when feeding automatically, so the automatic release device should be installed.

In the same processing, there will be a variety of principles. For example, our machines will have working principles and operating principles, and our precision hardware processing is the same. So what is the operation principle of precision hardware processing control system?

Generally, CNC computer lathe processing control system can control the machine tool to automatically start and stop, change direction and change speed of the spindle according to the digital program instruction. It can automatically control the feed speed, direction and processing road, stop the processing, select the tool and adjust the cutting amount and walking path according to the tool size, and complete various auxiliary actions required in the processing. When using CNC machine tool to process parts, it only needs to program the part graphics, process parameters and processing steps in the form of digital information, and input them into the machine tool control system, and then turn them into the command signal driving the servo mechanism after the processing of the stop operation, so as to control the harmonious action of all parts of the machine tool and automatically process the parts. When changing the processing object, only need to rewrite the program code, input to the machine tool, can be installed by numerical control instead of human brain and hands of the overall function, control the whole process of processing, manufacturing arbitrary complex parts. When we use machine tools to process parts, CNC computer lathe processing usually needs to stop the various actions of the machine tool, one is to control the sequence of action, the other is to control the displacement of each moving part of the machine tool. When the CNC computer lathe is processed by ordinary machine tools, such operations as start-up, parking, tool moving, reversing, spindle speed changing and cutting fluid switching are all controlled by manual. When automatic machine tool and copying machine tool are used, the processing operation and motion parameters of the above CNC computer lathe are controlled by imitating quantity through the installation of designed cam, profiling and block. Although they can process complex parts, and have certain sensitivity and generality, the machining accuracy of parts is affected by the manufacturing accuracy of cam and profiling, and the process is also affected It took a long time to prepare
