PRODUCT DESCRIPTION
How to make the size of aluminum parts more accurate?
1.Processing technology
In fact, most of the actual machining errors are caused by unreasonable machining processes, and the basic machining processes are guaranteed (such as âpre-roughing, first-faced rear holes, first large-faced small facesâ or fixtures in milling CNC machiningâ Reduce the of clamping times, try to use the combination of fixtures and other basic processing technology details, to minimize the machining error caused by iron filings on aluminum parts, because the aluminum parts are very soft, the excluded iron filings can easily cause machining errors in aluminum parts. . For example, in the FANUC or Central China Machining Center, the deep hole should be used as much as possible with the G83 command, so that the iron filings can be discharged instead of the G73 command.
2. Cutting three speed vc, feed rate f, cutting depth ap and tool compensation
In simple terms, under the premise of ensuring the processing quality and tool wear, the adjustment parameters fully exert the cutting performance of the tool, so that the cutting efficiency is the highest and the processing cost is the lowest.
In the CNC lathe, there are also factors such as cutter head wear compensation.
3. Tool setting
Inaccurate tool setting is also a factor in size error. Therefore, try to choose a good edge finder. If the machine has an automatic tool aligner, it is better.
