There are many materials of products processed by CNC machine tools, among which aluminum parts are one of the most processed. When using CNC machine tools to process aluminum parts, we must pay attention to these places if we want to make the processing size more stable.Mastars as a metal prototype maker, provides rapid sheet metal prototyping,rapid CNC service.rapid prototyping.

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

2. Material cooling problem. The workpiece may be deformed after cooling. This situation is often difficult to avoid. At this time, special attention should be paid to the use of coolant. The possibility of material deformation should also be considered during in-situ measurement.

3. Processing technology. Unreasonable processing technology is easy to cause dimensional error of workpiece. On the basis of ensuring the basic processing technology (such as "rough before fine, face before hole, large face before small face" in milling NC processing, or "reduce the clamping times and try to use combined fixture" and other basic processing technology details in the use of fixture), the processing error caused by iron filings on aluminum parts shall be minimized.

4. Parameter setting. Cutting speed, feed rate, cutting depth and tool compensation will affect the stability of machining, so special attention should be paid.

5. Tool selection. When processing aluminum parts, try to use special tools, which are often more targeted. For example, the special milling cutter for aluminum milling usually has a larger rake angle and spiral angle, and the cutting edge is sharper, which is more conducive to the processing of aluminum parts (such as anti chip formation), and the processed surface quality will be better.

6. Stress. Aluminum parts are made of soft materials, so special attention should be paid to the clamping strength. In addition, in the process of processing, the aluminum parts are opened in good condition and stand for a period of time before the next process is carried out to eliminate stress.

As a modern manufacturer of precision mechanical parts, mastars takes CNC processing as the core process, has physical factories and testing equipment, and integrates supporting manufacturing resources such as rapid prototyping, mold and post-treatment to provide customers with rapid proofing, small and medium-sized batch production, manufacturing and trial assembly, so as to truly achieve a one-stop service that saves worry and effort
