What types of metals can be processed by CNC machine tools?
CNC machine tools can process a variety of metals, ranging from common metals to special alloys, including but not limited to the following categories:
What are the methods of CNC machining metal?
The choice of CNC machining method depends on the design complexity, size requirements and production volume of the part. Combined with advanced CNC technology, these processes can efficiently produce high-quality metal parts and are widely used in automotive, aerospace, medical and industrial equipment and other fields.
In metal CNC machining, common CNC machining methods include the following, each method is suitable for different processing needs and process requirements:
What Factors Should Be Considered When Choosing A Metal For CNC Machining?
When selecting metal for CNC machining, several key factors should be considered based on project requirements and material properties:
1. Mechanical and physical properties
The metal should be selected based on the strength, hardness, durability, corrosion resistance, and electrical and thermal conductivity required by the part. High-strength materials such as tool steel are suitable for high-load scenarios, while aluminum with good ductility is suitable for parts with complex shapes.
2. Processing difficulty and time
The processing difficulty depends on the material properties. Easy-to-process materials save costs, while high-hardness materials may require special equipment and processes.
3. Cost
The choice of metal should balance the price of raw materials, processing complexity, and surface treatment costs. Aluminum is a cost-effective choice, while high-end materials such as titanium are more expensive.
4. Application scenarios
Different applications determine the material selection. For example, mechanical parts are mostly made of steel, aerospace often chooses lightweight heat-resistant metals, and electronic products tend to prefer aluminum or brass with good appearance.
