What are the advantages of CNC milling aluminum services in China?

The custom CNC milling services from China is the most common process used in the machining of aluminum parts. This is due to many advantages this provides over traditional machining processes.

Low Labor Costs

The CNC milling aluminum services do not require individual operators or any manual labor. The only labor required is the machinist who feeds the cutting program into the machinery. The setting up of machinery and starting the process is carried out by a single laborer. This makes the process of CNC milling cheaper than conventional methods.

High-Precision Results

The aluminum CNC machining service produces precise results. This is due to the automated nature of the process. The process guarantees accuracy with every axis it adds to the setup. The process is controlled by highly sophisticated computers resulting in much better and precise parts.

Repeatability

The CNC milling process makes the repeatability of the part easier. The automatic program is fed to the machine which runs in exactly the same way as the other producing identical parts in no time.

Safety

The process ensures the safety of workers as well. The cutting spindles can easily injure the operator but this completely automatic setup does not require the operator to work closely with such tools. This almost removes any risk of the operator getting hurt while working. Hence, CNC milling operation is a safe option for CNC milling manufacturers.

How cost-effective is the CNC milling aluminum service?

The CNC milling aluminum service is thought to be a costly process. This is due to the high costs of these machines. But this, in fact, is not true. Although the procuring of such machinery is expensive the process itself is cheaper than any other conventional method used for milling.

This is due to the following factors:

• The machining part takes lesser time to get milled and reduces the cost.
• The labor cost of the process is reduced as the operation is completely automatic.
• The parts created are precise and do not require added machining services resulting in increased cost.
• There is very little to no need for surface finishing services when CNC milling aluminum services are used.
• The material cost for this process is slower than other conventional methods because the risk of wastage is reduced in this process.
• The design can be optimized to optimize the price of the metal parts.

What are the different types of CNC milling operations?

Depending on different types of CNC milling operations, CNC milling is divided into different types:

Slot milling

Very thin milling cutters are used for this process. This operation is used to cut slots in the metal part. The workpiece is cut into two parts by making a slot throughout the depth of the part. This is done by saw mills.

Side Milling

As the name also explains, side milling results in the machining of the side of the workpiece. A vertical surface is obtained on the side of the workpiece by moving the cutter there. The vertical feed screw of the table helps in adjusting the depth of the process.

Straddle Milling

This process makes use of two side milling cutters at the same time. These cutters straddle the workpiece by operating on two vertical surfaces at a single cut.

Gang Milling

Two or more milling cutters are placed around the workpiece to operate on the horizontal surfaces only. This setting is called gang milling. The process is efficient and more productive.

Form Milling

This milling process is used to work with the contours of the workpiece. Rapid tooling manufacturers come across more complicated parts every day. Form milling help to shape and cut the contours of the metal part.

What techniques are involved in CNC milling aluminum services?

CNC milling aluminum service makes use of many different operations and techniques to create high precision parts. The complete process uses different techniques to make the process more productive.

Spindle Speed

Spindle speed affects the result to a great extent. The high speed of the spindle provides small chips of the metal cutting the metal part very fast. When the spindle speed is turned down, it cuts the metal in a long stringy method. This technique is used to shape the metal part differently.

Feed speed

The feed speed of the milling tool is the total distance traveled by the tool in one revolution. The feed rate is increased to make the tool work more per revolution. This makes the process more efficient and generates a faster result. The feed speed is increased and decreased according to the custom requirements of the customer.

Spindle Pressure

Some metals harden while processing. This needs the slow-moving of the spindle with a higher pressure. The fast spindle speed does not allow the tool to go through metal. The technique is used differently with different metals.

What kinds of parts can be produced using CNC milling services?

CNC milling services can be applied to different materials to produce parts from different industries. The CNC milling services are mostly used to create parts of different types using the following materials:

• Aluminum

How to avoid the chance of deformation in the CNC aluminum milling process?

Aluminum has a relatively large thermal expansion coefficient than any other metal. This can easily deform the material when passed through a CNC machining process. Here are some ways to minimize the onset of deformation in CNC milled products.

• Eliminating the internal stress of the metal before the process starts.
• Avoiding heat concentration by using the method of Symmetrical Machining.
• Reducing the chance of deformation due to cavities by processing the metal layer by layer in a method called the Stratified Multiple Machining.
• Controlling the amount of cutting force by setting an appropriate cutting parameter.
• Optimizing the performance of cutting tools by adjusting the right geometric factors like the front angle, rear angle, main deflection angle, helix angle, tool wear, cutter teeth, etc.

• Working on improving the milling tool structure by reducing the number of teeth and using a wider chip space.
• Reducing clamping deformation by implementing the method of Two-Times Compression.
• Instead of pushing the metal pieces directly into CNC milling aluminum, we Pre-drill all the parts to make right-sized holes and then continue with Aluminum CNC machining service.
• Using two different approaches for rough cutting and finishing to shape the metal into its final form. This greatly suppresses the chances of deformation in the last stage of our custom CNC milling services from China.

Bead Blasting

The CNC milled parts have rough surfaces with hard textures. Bead blasting helps in providing a matte finish with a light texture. The metal part gives a smooth visual once exposed to this process. Experts at Sunrise Metal recommend this process for machined parts.

Powder Coating

Powder coating is the most required surface finish by CNC milled parts. Dry powder is applied to the metal part electrostatically and is then exposed to heat to cure the coating. This coating makes the metal part wear and corrosion-resistant. Powder coating has higher impact resistance and hence the large range of colors are available in the process.

Chromate Plating

This is a process where chromate treatments provide a decorative finish to metal alloys. It makes the final product corrosion-resistant and protects against chemical attacks. Chromate is a very good pre-treatment for paint, especially for aluminum products.

Liquid Painting

Liquid painting is applied to finished and assembled industrial products, which is otherwise not possible with powder coating. This makes it a popular choice for most aluminum components prepared as the masking is also easier. It also offers quick and easy color change. Smooth surfaces can be prepared and the final top coating gives a luscious coating for automobile and other metal parts.

What is the milling spindle speed for CNC aluminum?

Milling spindle speed is a major factor that affects the design of the metal part. The CNC milling of a metal part can severely depend upon the spindle speed. The machine can process at any speed but there’s a specific speed for every metal at which the process is stable. This is the ideal speed and is designated for all different metals.

If the spindle speed is higher than the ideal speed

The higher speed of the spindle can cause the CNC milling process to start and stop, causing the wearing of the machine. The higher speed is not always the required speed. The risk of machine breakdown increases with high speed.

If the machine is working at the ideal speed

The ideal speed is not a specific speed. It is different for different metals. For aluminum, it is 15000 rpm. At this speed, aluminum is milled perfectly. There is no chance of breaking down of machine or the lowering of productivity and efficiency.

If the spindle speed slower than the ideal speed

The low spindle speed can cause the machine to mill slowly hence resulting in low temperature and high-pressure requirements. This can affect the metal part efficiency as well. The sharpness required in the part can also be affected by the lower speed.
