A cnc processing plant will always carefully analyze the difficulties, sort out the technological process, and reconstruct as necessary whenever it receives a new key task. This will allow the plant to have a higher product qualification rate. There is an essential component, which consists of a number of different parts. It is not possible to loosen the connection between the parts, so there must be adequate space in between them to allow for free and flexible movement. Only a small portion of the hair is accounted for in the machining accuracy of its mating surface. Scraping and grinding by hand serves as your guarantee.

After the precision parts machining center took over, the machining technology and measurement methods of the parts were carefully studied. The control problems of the machining tools, measurement methods, and the fit clearance after surface treatment were improved as a result of these studies. The lack of rigidity of the slender shaft, for instance, makes it very easy for the slender shaft processing method to deform while it is being processed. This has a significant influence on both the accuracy and the quality of the processing done on the slender shaft. To this end, the following solutions are frequently implemented in production in order to fix the problem.

(1) Develop a more effective custom cnc milling method for clamping the workpiece
Because of the large cutting allowance and the large cutting force that is applied to the workpiece, the clamping top method is typically utilized during rough machining. Additionally, the tailstock top typically utilizes an elastic top, which enables the workpiece to freely extend in the axial direction.On the other hand, because there is a limit to the top's elasticity, there is also a limit to the axial elongation; consequently, the top tightening force is not very great.When cutting at a high speed and through a large volume, there is a possibility that the workpiece will be cut away from the top.Using the Kara method will protect you from experiencing this phenomenon.

When performing fine turning operations, the precision parts machining center utilizes the double-top method (at this point, the tailstock should be using the elastic top), which is advantageous for improving the accuracy. The accuracy of the center hole needs to be worked on first and foremost.

(2) Inserting the tools into the tool holder
When turning thin shafts, the tool holder is an extremely important piece of auxiliary equipment to have.When performing machining operations, the use of a follower rest can reduce the impact of radial cutting forces, and CNC parts can be processed to reduce cutting vibration and workpiece deformation. However, adjustments must be made with caution in order to ensure that the center of the follower rest is aligned with the center of the machine tool.

(3) Adopt reverse feed
When turning a thin shaft, the turning tool is frequently fed in the direction of the tailstock. This causes the feed force that is applied by the tool to the workpiece to be directed cnc machining service toward the tailstock. As a result, the workpiece has a tendency to elongate axially, and the karaoke tool is significantly reduced.The bending deformation that was caused by the elongation of the workpiece is eliminated.

(4) Lathes and lathe tools designed for turning thin shafts
It is common practice for turning tools designed for turning thin shafts to have large rake angles and leading angles. These features make cutting easier and help reduce radial vibration and bending deformation.The chip breaking process is simplified thanks to the roughing turning tool's chip breaker, which is located on the rake face.The edges of fine turning knives typically have a slight negative inclination, which encourages the flow of chips to the surface that is being machined.

The color tone of electroplated tin-cobalt alloy is comparable to that of electroplated cobalt; however, the former has a softer appearance and enjoys greater popularity. The majority of chromium that is used today comes from countries outside the United States. Electroplating with cobalt is difficult for barrel plating, but electroplating with tin-cobalt alloys is appropriate for barrel plating of small parts. In addition, the electroplated tin-cobalt alloy has excellent throwing ability and the ability to barrel plate, which allows it to be used on workpieces that have complex shapes. If a double layer of nickel plating is applied to the base layer, the corrosion resistance of the finished product is equivalent to that of chrome plating. During the CNC machining of the aluminum alloy shell, a treatment called dipping with chromate should be performed. This will help prevent the surface from becoming discolored and will also improve the shell's resistance to corrosion.

It has a feel similar to pale rose and excellent resistance to corrosion. Additionally, the color is pale rose. It is possible to achieve a surface with a high gloss by applying an electroplating of tin-nickel alloy to a substrate that is already shiny or by applying a layer of bright nickel electroplating. The surface's original condition has a chance of being revealed if the CNC machining of the aluminum alloy casing is electroplated after it has been finished with a matte finish. Because there is almost no leveling effect and the throwing ability of the electroplating layer is very excellent, it is suitable for the electroplating of extremely fine lines and rotating processed products.

The low-tin bronze coating of the aluminum alloy shell has a color that can be described as either pink or golden, and the crystal is very fine. It also has a high resistance to corrosion and performs well when it comes to polishing and rotation. In the light industry and handicraft industry, as well as the mechanical instrument industry and other industries, it is frequently utilized as a protective-decorative nickel bottom layer. The coating made of medium tin bronze has a color that can be described as golden yellow, and its resistance to corrosion is above average. Used primarily as a foundation for the application of decorative chrome plating.

People have put forward various new requirements for the surface performance and appearance of CNC machining of aluminum alloy shells as a result of the development of science and technology. , turn to smoky shades, as well as shades that are as understated as satin. Because of this, electroplating alloys came into existence. In this section, Huiwen provides a concise introduction to a number of decorative electroplating alloys that are utilized in product finishes.
