Aluminum Parts Machining Cost

Aluminum parts have the least loss of tools and equipment, and the processing speed is the fastest among all metals.

The cost composition of aluminum parts: material cost + processing cost. Average hours per hour for Aluminum CNC Machining in Tirapid are:

3-axis CNC machining: $20~40/hour.
4-axis CNC machining: $30~50/hour.
5-axis CNC machining: $40~100/hour.
Lathe processing: $30~60/hour.

The above is for reference only. Factors such as the complexity of the part, the cost of the materials, and the setup costs of the mechanic all affect the total cost.

How to solve the deformation problem of aluminum thin plate parts?

Aluminum plate specification:

Thickness: less than 5mm (0.196inch),
Length & width: greater than 300mm (15.748inch),
Length & Width: less than 600mm (23.622 inches).
Flatness requirement: // 0.02mm or less
Part structure: There are large-area hollow structures and porous parts.

There are 6 solutions:

●Perform secondary leveling processing
When the flatness of raw materials does not meet the requirements, secondary leveling processing can be carried out.

●Increase the thickness of raw materials
Raw material thickness increased by 3-5mm. For example, if the thickness of the product part is 5mm, then the minimum thickness of the raw material needs to be 8-10mm.

●Drilling first and then milling the surface
The hole and shape of the product parts are processed first, and then the size of the surface is processed.

●Increase the number of milling
Increase the number of plane milling and perform multi-layer processing. After each process of milling, check whether there is any change in the plane size, and adjust the process in time.

●Reduce the amount of cutting each time
The amount of milling of the plane is minimized, and it is not necessary to process it in place at one time, and leave 1-2 hours for the material to release the stress.

●Milling direction is consistent
The running direction of the tool needs to be consistent, and the feed rate, depth of cut, and spindle speed cannot be changed arbitrarily.

What is the price of CNC aluminum sheet?

The average price of aluminum sheets commonly used in China is USD6~10/KG.

Additional shipping and cutting charges apply for very small quantities. Then the total price of a piece of aluminum material will also rise accordingly.

Special aluminum plate prices are priced according to customization, such as imported materials and customized materials.

What is aircraft grade aluminum?

In industrial aluminum, 7075 aluminum alloy is the representative of aviation aluminum. It has strong corrosion resistance, light weight, high strength, and a higher melting point than 6061.

7075 aluminum is suitable for a variety of surface treatments, such as hard anodizing, electroplating and other secondary finishing.

Therefore, it is used in the industry fields of aircraft accessories, defense applications, high-end automobiles, gears and shafts.

Are aluminum RC parts better than plastic?

Yes, of the RC parts, half are aluminum.

The choice of aluminum to make RC parts not only improves the quality of the parts, but also has a functional effect.

The precision of aluminum parts is higher than that of plastic parts. In key components, the use of metal aluminum parts can greatly improve the precision of mechanical properties.

The temperature resistance of plastic parts is not as good as that of aluminum. Aluminum can have better thermal performance and also increase the service life of parts
