CNC machining method for aluminum alloy
1、 Overview
With the development of modern industry, aluminum alloy, as an important structural material, is widely used in fields such as aviation, automobiles, ships, electronics, etc.
As an efficient and efficient processing method, CNC machining technology is widely used in the processing of aluminum alloys.
This article will introduce the methods and techniques for CNC machining of aluminum alloys.
2、 Selection of Aluminum Alloy Materials
There are various types of aluminum alloy materials, and different types of aluminum alloys have different mechanical properties and properties.
Before CNC machining, it is necessary to select appropriate aluminum alloy materials based on specific machining requirements.
Generally speaking, commonly used aluminum alloy materials include aluminum copper alloy, aluminum zinc alloy, aluminum magnesium alloy, etc.
The hardness and cutting performance of different materials also vary, so choosing the appropriate material is crucial for improving machining quality and efficiency.
3、 CNC machining process
1. Processing preparation: Firstly, it is necessary to prepare the required aluminum alloy materials and processing tools according to the drawings and requirements of the parts.
The size of the material should match the requirements of the drawing, and the processing tools should also be kept in good condition.
2. Design machining path: Based on the drawings and requirements of the parts, use CAD/CAM software to design a suitable machining path.
The machining path should minimize the tool movement distance as much as possible to improve machining efficiency.
3. Installation of fixtures: Based on the design of the machining path, select a suitable fixture for fixing the parts.
The selection of fixtures requires the stability and machining accuracy of the parts.
4. Processing operation: According to the design of the processing path, fix the aluminum alloy material on the processing center and perform the processing operation.
During the machining process, attention should be paid to the selection of cutting tools, the adjustment of cutting speed and feed speed, in order to ensure machining quality and efficiency.
5. Inspection and repair: After completing the machining, the parts need to be inspected and repaired.
Check whether the size and shape of the parts meet the requirements through measuring tools, and make necessary adjustments and repairs.
4、 CNC processing precautions
1. Tool selection: Aluminum alloy has good cutting performance, so high-speed steel tools or hard alloy tools can be selected for processing.
When selecting a tool, it is necessary to choose the appropriate tool material and shape based on different cutting conditions.
2. Cutting speed and feed speed: Aluminum alloy has a higher cutting speed, and a higher cutting speed and feed speed can be selected.
However, adjustments should be made according to the specific processing situation to ensure processing quality and efficiency.
3. Cooling and lubrication: When machining aluminum alloy CNC, attention should be paid to maintaining cooling and lubrication in the cutting area.
Cutting fluid can be used for cooling and lubrication to reduce cutting heat and friction, improve machining quality and tool life.
4. Machining accuracy control: When performing CNC machining, attention should be paid to controlling the machining accuracy.
