Advantages of precision hardware processing

With the rapid development of the processing industry, some of our processing industries are also in continuous development. The precision hardware processing is the same, and the development is still very good. What are its advantages and why is it so popular?

CNC machining precision of precision hardware shaft is high, with stable processing quality;
It can carry out multi coordinate linkage and process complex shape parts;
When the CNC machining parts of precision hardware are changed, only the NC program needs to be changed, which can save the production preparation time;

Tangxia precision hardware processing

The machine tool itself has high precision and rigidity, so it can choose favorable processing amount and high productivity (generally 3 to 5 times of ordinary machine tool);
High degree of automation of machine tools can reduce labor intensity;

Advantages of CNC machining

With the change of the times, our very products need to be processed to get the corresponding effect, and the processing method is also very good, not only to get that effect, CNC processing is one of them, so where are the advantages of CNC processing reflected?

① A large number of tooling is reduced, and complex tooling is not needed to process parts with complex shapes. If you want to change the shape and size of parts, you only need to modify the part processing program, which is suitable for the development and modification of new products.

② CNC machining has the advantages of stable machining quality, high machining precision and high repetition accuracy, which can meet the processing requirements of aircraft.

CNC machining

③ In the case of multi variety and small batch production, the production efficiency is higher, the time of production preparation, machine tool adjustment and process inspection can be reduced, and the cutting time is reduced due to the use of the best cutting amount.

④ It can machine complex surface which is difficult to process by conventional method, and even can process some parts which cannot be observed.

The reason of tool unbalance in CNC machining

In the process of processing, there will be a variety of problems, these problems are often occurred, may be because we do not operate well in the process of operation, caused by CNC machining is the same, so what are the causes of CNC machining tool imbalance?

The main reason for CNC machining is that the tool design is asymmetric, there are defects in the tool body, and all the adjustment of the tool. The correct balance of the tool can significantly reduce noise and vibration, which increases the tool life and improves the accuracy consistency of parts.

The centrifugal force of CNC machining center is proportional to the square of velocity to amplify the vibration caused by unbalance. The vibration increase of CNC machining center caused by the machining center minimizes the service life of bearing bush, bearing, shaft, spindle and gear.

Before balancing the tool in CNC machining center, it is necessary to measure the unbalance and the angle position of each selected correction plane. These variables are measured on two general types of balancing machines: non rotating or gravity machines are used to measure single plane unbalance, while rotary or centrifuge is used to measure single plane or two plane unbalance.

After measuring the magnitude and angle of the unbalance in the correct plane, you can correct it by adding or removing material from the workpiece. For the components which are not tools, the most widely used material adding method of drilling center is welding counterweight on the components.

Characteristics of CNC machine tools

CNC (numerical control machine tool) is the abbreviation of computer numerical control machine tool. It is an automatic machine tool equipped with program control system. The control system can process and decode the program with control code or other symbol instructions logically, so that the machine tool can move and process parts. Today we’ll take a look at its characteristics.

The operation and monitoring of CNC machine tools are all completed in this CNC unit, which is the brain of CNC machine tools. Compared with ordinary machine tools, CNC machine tools have the following characteristics:

1、 High machining precision and stable machining quality;

2、 It can carry out multi coordinate linkage and process complex shape parts;

3、 When the machining parts are changed, only the NC program needs to be changed, which can save the production preparation time;

Prospect of CNC processing

CNC is also called computer gong, cncch or CNC machine tool. In fact, it is a kind of name in Hong Kong. Later, it was introduced into the Pearl River Delta of the mainland. It is actually a CNC milling machine. In Guangzhou, Jiangsu, Zhejiang and Shanghai, there are people called “CNC machining center”. General CNC machining usually refers to precision machining, CNC machining lathe, CNC milling machine, CNC boring milling machine, etc. Today we will talk about the prospect of CNC processing industry.

As an industry widely used in the market for mold processing and production, with the development of market economy, the decline of demand and the increase of peer competition pressure, technological breakthrough or price war is urgent.

1、 From the technical reform, the future development center must make a breakthrough from the most basic technology, realize the multi-directional upgrading from the mechanical and operational aspects, and achieve the technical update of the industry. Only with unique technology can we better cope with the future competition.

2、 In terms of service improvement, the competition in the industry is not only in technology, but also in service. Service is the relationship. If the service is done well, customers will continue to choose cooperation. Therefore, in the limited time, we should improve the service in essence.

Automatic processing quality

For the quality of processing, it depends on what factors, including many, may be the processing method, may also depend on the material, these are possible, automatic parts processing is the same, then the quality of automatic parts processing depends on what reason?

The quality of the machine depends on the processing quality of the parts and the assembly quality of the machine. The machining quality of the parts includes the machining accuracy and the surface quality of the parts. The machining accuracy refers to the degree to which the actual geometric parameters of the parts are consistent with the ideal geometric parameters. The difference between them is called machining error. The size of machining error reflects the level of machining accuracy. The larger the error is, the lower the machining accuracy is, the smaller the error is, the higher the machining accuracy is; the main factors affecting the machining accuracy are: dimensional accuracy, the conformity between the actual size of the part after processing and the tolerance zone center of the part size.

The machining error of Automatic Parts reflects the machining accuracy. The larger the error is, the lower the machining accuracy is, the smaller the error is, the higher the machining accuracy is; the main factors affecting the machining accuracy are: dimensional accuracy, the conformity between the actual size of the part after processing and the tolerance zone center of the part size. Compared with the method of producing parts with die casting die, it avoids the uneconomical of opening the die when manufacturing small batch parts, and shortens the production cycle greatly. At the same time, the correct clamping and positioning and reasonable processing technology make the processed parts have high precision and surface finish, which is not achieved by die casting process. Moreover, the density of extruded aluminum profile is higher than that of die casting. In addition, this method is different from the general single part machining production, it can batch produce a bed of parts. If the working table of the machine tool is large enough, the bottom plate can be made larger, and several aluminum materials can be arranged at a time, then the processing efficiency can be further improved and the number of tool changes is relatively reduced. If there are features on the side of the part to be processed, such as a round hole to be drilled, then after the part is cut off on the B side, the fixture shall be manufactured, and the part shall be installed

CNC machining features

It is precisely because of the good characteristics of this processing, people will continue to use, will continue to choose, it is enough to prove that this processing is how good, CNC processing, then CNC machining parts characteristics is what? What advantages can be embodied?

The features of CNC machining parts are as follows: after the parts are clamped once, the CNC system can control the machine tool to automatically select and change the tool according to different working procedures; it can automatically change the spindle speed, feed rate and the movement track of the cutter relative to the workpiece and other auxiliary functions, and automatically drill, spot face, ream, bore, tap thread on each machining surface of the workpiece Milling and other multi process processing.

CNC processing in Dongguan

Because CNC machining center can finish many kinds of working procedures in a centralized and automatic way, it can avoid man-made operation error, reduce the time of workpiece clamping, measuring and machine tool adjustment, as well as the time of workpiece turnover, handling and storage, and greatly improve the processing efficiency and accuracy, so it has good economic benefits.

CNC machining center can be divided into vertical machining center and horizontal machining according to the position of spindle in space
