Why do We Choose CNC Machining Aluminum Parts？
by jin
One of the most widely used materials for CNC machined parts is aluminum. Here are some reasons to choose it .
rapid machine
Since aluminum is relatively dimensionally stable, you can remove a lot of it while still controlling residual tension. It can be bead blasted for a matte surface or anodized for a consistent aesthetic finish and added corrosion resistance to get a beautiful finish using carbide tooling and contemporary coolants.
higher resistance to corrosion
Although corrosion resistance varies between grades, aluminum is a great material choice if you need it. When aluminum is exposed, on the other hand, it develops a passivating layer of aluminum oxide that seals the surface and stops further oxidation and erosion.
High conductivity
Although copper is frequently the preferred material for conductivity, aluminum is frequently used in electrical components since it is both cheaper and lighter. Because of its excellent thermal conductivity, it is frequently used for heat sinks and heat dissipation.
Recyclable
Recycling aluminum consumes significantly less energy than making it, and it can be used repeatedly as long as impurities are kept under control.
Aesthetics
We've already discussed how well this material can be machined and how aluminum naturally resists corrosion, but for added aesthetics, you can anodize it to get it in a variety of colors.This method of surface finishing improves a material's wear and corrosion resistance while also making it simple to add color. Through the use of acids and an electrolytic procedure, the passivating oxidized layer's thickness is increased. This coating is extremely durable since aluminum oxide is a strong ceramic.
In addition, the high strength-to-weight ratio and the choice of alloy properties are also advantages of aluminum.Your choice of material is vital and will be based on the qualities you require. For the reasons mentioned above, aluminum is frequently a fantastic option, but there are many other metal and plastic choices available.If you want to know more，please click here:https://www.jtrmachine.com/cnc-machining-aluminum-parts...

What Sets CNC Machining Apart from Conventional Machining?
by jin
CNC machining, which uses digital instructions to run machine tools, tools, and workpieces for processing, is extensively used in manufacturing for turning, milling, grinding, and other processes. Other applications for it include engraving, cutting, and lettering. CNC technology allows for the manufacturing of intricate and high-precision objects while also improving machining accuracy and production efficiency.The following benefits of CNC machine tools are brought about by the use of computer control:
1.Excellent adaptability. In order to machine parts with complex shapes, a lot less tooling is needed, and complex tooling is not necessary. The component processing software, which is appropriate for the creation of new products and their modifications, can be changed to alter the part's size and shape. As long as the program is altered, it can process new parts during CNC machining. CNC machine tools can adjust to market competitiveness since they are automated, flexible, and highly efficient.
2.Stable processing quality, high processing accuracy and high production efficiency. CNC machining improves product consistency by removing worker fatigue, carelessness, estimate mistakes, and other human defects on Conventional Machining.
3.Process complex parts.It is capable of processing any shape of space surface, including propellers, turbine blades, and any trajectory movement.
4.It can lessen the amount of labor required and enhance working conditions. Excluding CNC workers from processing for the vast majority of the time saves a lot of labor.
The increased precision of parts made by CNC workers on CNC machining as opposed to parts made by traditional workers on conventional machining saves time. For more information， please click here....

What is the Difference between CNC Turning and CNC Milling？
by jin
CNC turning and CNC milling are both subtractive manufacturing processes, which means that they remove material from a workpiece to create a desired shape.In CNC turning, the workpiece is held stationary and a single-point cutting tool rotates around it. This process is well-suited for creating cylindrical parts, such as shafts, rods, and tubes.In CNC milling, the workpiece is moved in multiple axes while a rotating cutting tool cuts away material. This process is well-suited for creating complex shapes, such as gears, molds, and prototypes.
Here are some additional points to consider when choosing between CNC turning and CNC milling:
Cost: CNC turning is typically less expensive than CNC milling, especially for simple parts.
Lead time: CNC turning can typically produce parts more quickly than CNC milling.
Precision: CNC turning can achieve a higher degree of precision than CNC milling, especially for cylindrical parts.
Repeatability: CNC turning is more repeatable than CNC milling, meaning that parts produced with CNC turning are more likely to be identical.
Complexity of the part: CNC milling is more versatile than CNC turning and can be used to create more complex parts.
Ultimately, the best process for a particular job will depend on the specific requirements of the part. If you need to create a cylindrical part quickly and precisely, CNC turning is a good option. If you need to create a complex shape, CNC milling is a better choice. If you want more information, please click here：https://www.jtrmachine.com/cnc-machining-service...
