When machining aluminum parts with CNC machine tools,vqlYoYike manufacturer company
If you want to make the machining size more stable, you must pay attention to these places.vqlYoYike manufacturer company

1. The state of the machine tool. Whether the machining is stable or not depends to a large extent on the state of the machine tool itself. Before machining, we have to check the machine tool itself and start the equipment after there is no problem. 2. Material cooling problem. The workpiece may deform after cooling.vqlYoYike manufacturer company

This situation is often unavoidable, and special attention needs to be paid to the use of coolant at this time. The possibility of material deformation should also be considered when performing in-situ measurements. 3. machining technology.vqlYoYike manufacturer company

The unreasonable machining technology can easily cause the size error of the workpiece. In ensuring the basic machining technology (such as "coarse first, then fine, first face and then hole, first large face and then small face" in CNC milling, or "reduce the number of clamping times and try to use combined fixtures" in the use of fixtures and other basic machining process details) On the basis of this, it is necessary to minimize the machining error caused by iron filings to aluminum parts. 4. Parameter setting.vqlYoYike manufacturer company

Cutting factors such as cutting speed, feed, depth of cut and tool compensation will affect the stability of machining, so special attention should be paid. 5. Tool selection. When machining aluminum parts, try to use special tools, which are often more targeted.vqlYoYike manufacturer company

For example, the milling cutter specially used for milling aluminum usually has larger rake angle and helix angle, sharper cutting edge, which is more conducive to the machining of aluminum parts (such as anti-built-up edge), and the surface quality will be better. 6. Stress.vqlYoYike manufacturer company

The aluminum material is soft, so you need to pay special attention to the clamping force. In addition, during machining, the aluminum parts are roughed and left for a period of time before proceeding to the next process to eliminate stress.vqlYoYike manufacturer company

In addition, aluminum parts should also pay attention to chip removal and the amount of cutting fluid used in the machining of aluminum parts.vqlYoYike manufacturer company

There are many factors affecting the machining stability of aluminum parts, so it is necessary to respond flexibly during machining, and analyze specific problems in detail. Stable machine tools, reasonable machining techniques and tools, and the skill level of operators are all factors that affect product quality.
