Matters needing attention when processing aluminum parts

CNC machine tool processing products are various in material, among which aluminum is one of the most processed. When using CNC machine tools to process aluminum parts, to make the processing size more stable, the following aspects must be paid attention to.

1. The state of the machine tool. Whether the processing is stable or not depends largely on the state of the machine tool itself. Before processing, we should check the machine tool itself and start the equipment after no problem.

2. Material cooling. The workpiece may deform after cooling. This situation is often unavoidable and requires special attention to the use of coolant. The possibility of material deformation should also be considered when making in-place measurements.

3, processing technology. Unreasonable processing technology is easy to cause the size error of the workpiece. On the basis of ensuring the basic processing technology (such as milling CNC machining "first coarse after fine, first surface after hole, first big surface after small surface" or fixture in use "reduce the number of clamping, try to use the combination of fixture" and other basic processing details), to minimize the processing error caused by iron filings on aluminum.

4. Parameter Settings. Cutting speed, feed, cutting depth and tool compensation all affect the stability of machining, so special attention should be paid to them.

5, tool selection. When processing aluminum parts, try to use special cutting tools, which are often more targeted. Such as milling aluminum special milling cutter usually front Angle and spiral Angle will be larger, the cutting edge is sharper, more conducive to the processing of aluminum parts (such as anti chip tumor), the surface quality of processing will be better.

6. Stress. Aluminum material is soft, so we need to pay special attention to the clamping strength. In addition, in the processing, the aluminum parts open thick intact static for a period of time before the next process, in order to eliminate stress.

In addition, aluminum parts in the processing should also pay attention to chip removal and the amount of cutting fluid and other issues. There are many factors that affect the processing stability of aluminum parts, so it is necessary to deal with them flexibly and analyze the specific problems. Stable machine tools, reasonable processing technology and cutting tools, as well as the technical level of operators are factors that affect product quality.
