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 assembled for further processing

In a processing, there will be a variety of processes, these processes, are to make processing products, change better method, hardware processing is the same, it also has a variety of processes, so what are the surface treatment processes of hardware processing?

Hardware processing: surface processing can be divided into: Hardware spray painting processing, electroplating, surface polishing processing, metal corrosion processing and so on.

1. Spray paint processing: now the hardware factory in the production of large hardware products are used in the spray painting process, through the spray painting process to prevent the hardware from rusting, such as: daily necessities, electrical shell, handicrafts, etc.

1. Electroplating: electroplating is also the most extensive processing technology of hardware processing. Through modern technology, the appearance of hardware parts is electroplated to ensure that the product will not mildew and rust under long-term use. The common electroplating processes are: screws, stamping parts, batteries, car parts, accessories and so on.
2. Surface polishing processing: surface polishing processing is generally used in daily necessities for a long time. After surface burring treatment of hardware products, for example, we produce a comb, the comb is made of hardware by stamping, then the edge of the comb is very sharp, we have to polish the sharp part of the corner into a lubricating face, so in operation In the process of using, it will not cause harm to human body.

For operators, for their own processing things, we must know how to operate, but also know what the precautions are, so that it is useful for themselves, otherwise, when processing, there will be accidents, Dongguan CNC parts processing is the same, so what problems should be paid attention to in parts processing?

1. It is necessary to follow the safety operation regulations of machining center.
2. Wear protective equipment and cuff before operation. It is forbidden to wear scarf, gloves, tie and apron. The braid of female workers should be tied in the hat.
3. Check whether the tool compensation, zero point of machine tool and workpiece are correct before starting the machine.
4. The relative orientation of each button should meet the operation requirements. Carefully compile and input NC program.

1. Check the operation status of protection, insurance, signal, orientation, mechanical transmission part, electrical and hydraulic digital display system on the equipment, and carry out cutting under all normal conditions.
2. Before CNC machining of parts, the machine tool should be run in order to check the operation conditions of smooth, mechanical, electrical, hydraulic and digital display systems. Cutting can be carried out under all normal conditions.
3. After the machine tool enters the processing operation according to the program, the operator is forbidden to contact the workpiece, cutting tool and transmission part of the moving person, and it is forbidden to transfer or take things through the transmission part of the machine tool.
4. It is necessary to park the machine when adjusting the machine tool, clamping the workpiece and cutting tool and wiping the machine tool.
5. Things or other articles are not allowed to be placed on electrical appliances, operation cabinet and protective cover.
6. It is forbidden to remove iron filings directly by hand, and should be cleaned with special tools.

CNC parts processing in Dongguan

1. In case of abnormal conditions and alarm signals, park the vehicle immediately and ask relevant personnel to check.
2. It is forbidden to leave the operation post when the machine tool is running. If it is necessary to leave the machine tool for some reason, put the working table in the central position and return the cutter bar. It is necessary to park the vehicle and cut off the power supply of the main engine.

1. Accurate design drawings are required

It has just been said that precision hardware processing is to process some hardware parts with small diameter, so the design drawings of this product should be accurate, and the parts and components are far from accurate. If the drawings are not accurate, it may cause that the parts produced can not be used, thus increasing the production cost.

1. Raw materials for precision hardware processing

The products of precision hardware processing are usually used in aviation, clocks and other places with high requirements on raw material quality, so the requirements for the quality of processed hardware products are also quite high, so the high-quality raw materials are usually used in precision hardware processing.

1. Cost estimation

In many cases, the products of precision hardware processing are of relatively low value, so we should also study this point in the estimated time, which requires that the cost of precision hardware processing must be controlled. Improving production skills and increasing production efficiency play an important role in controlling capital.

Precision hardware processing is a high requirement for all aspects of the process, but as long as these concerns are achieved, it can still be done well under normal conditions.

1、 Basic machining route of shaft parts

The main machining situation of shaft parts is the general situation of outer circle and common special shape. Therefore, it is necessary to select the appropriate processing method for bucket force according to the requirements of various Accuracy grades and profile roughness. There are four basic processing routes.

First of all, it is the processing route from rough turning to semi finishing turning, and then to finishing turning, which is also the main process route for the pin cylindrical machining of shaft parts with common materials; The second is from rough turning to semi finishing turning, and then to rough grinding. For ferrous metal materials and parts with high accuracy requirements, general coarseness requirements are small and need to be hardened, this processing route is a good choice for bucket force, because grinding is an ideal subsequent processing procedure for bucket force; The three routes are from rough turning to semi finishing turning, then to finishing turning and diamond turning. This kind of processing route is specially used to process non-ferrous materials. Because the hardness of non-ferrous metals is small, it is easy to block the gap between sand grains. If grinding is used, it is not easy to obtain the required profile roughness, so finish turning and diamond turning must be adopted; The latter processing route is from rough turning to semi finishing turning, then to rough grinding, fine grinding and finishing. This route is often used for the parts which are hardened by ferrous metal and have high requirements for precision and low requirements for coarseness value.

2、 Pre machining of shaft parts

Before turning the outer circle of shaft parts, some preparatory procedures should be carried out, which is the pre machining process of shaft parts. Straightening is an important preparatory process. Because the workpiece blank in the manufacturing, transportation and storage process, often occurs bending deformation. In order to ensure reliable clamping and uniform distribution of machining allowance, straightening is carried out by various presses or straightening machines in cold state.

3、 Positioning datum for machining shaft parts

First of all, the center hole of the workpiece is used as the positioning reference for machining. In the machining of shaft parts, the general situation of each outer circle, the coaxiality of taper hole and thread profile, and the verticality of the end facing torsion axis are all important appearance of position accuracy. These profiles are generally based on the center line of the shaft as the design basis, positioning with the center hole, and the principle of appropriate datum coincidence. The center hole is not only the positioning datum in turning, but also the locating datum and grinding datum of other machining processes. When two center holes are used for positioning, multiple outer circles and end faces can be machined in one clamping process.

Secondly, the outer circle and the center hole are used as the positioning datum. This method effectively overcomes the error and fallacy of poor rigidity of the central hole positioning, especially when machining heavy workpieces, the positioning of the central hole will cause unstable clamping and the cutting parameters can not be too large. If the outer circle and the center hole are used as the positioning datum, there is no need to worry about this problem. In rough machining, the general situation of the shaft’s outer circle and a central hole are used as the positioning reference, which can bear a large cutting torque in the machining, which is a common positioning method for shaft parts.

The third is to take the general situation of two outer circles as the positioning datum of machining. When machining the inner hole of the hollow shaft, the center hole can not be used as the positioning reference, so the general situation of the two outer circles of the shaft should be used as the positioning reference. When machining machine tool spindle, two supporting journal is often used as positioning reference, which can effectively ensure the coaxiality requirement of taper hole relative to supporting journal, and eliminate the error caused by the non coincidence of datum.

The cone plug with a central hole is used as the positioning reference for machining. This method is widely used in the processing of hollow shaft cylindrical profile.

4、 Clamping of shaft parts

The machining of cone plug and cone sleeve mandrel must have high machining accuracy. The center hole is not only the positioning reference for manufacturing itself, but also the datum for finishing the outer circle of hollow shaft. It is necessary to ensure that there is a high coaxiality between the cone surface and the central hole on the cone plug or cone sleeve mandrel. Therefore, when selecting the clamping mode, attention should be paid to reduce the installation times of the cone plug as far as possible, so as to reduce the repeated installation error of the parts. In actual production, the cone plug installation in the future, generally speaking, before the completion of processing, will not be removed or replaced in the middle of processing
