Precision mechanical parts processing, if high precision accuracy is guaranteed?
Many mechanical parts processing factories like to rhetoric. Whenever there is an order for precision mechanical parts processing, they will promise to customers that they can guarantee the accuracy. When it comes to shipping, it is not the case. Customers must keep their eyes open and choose accurately. CNC lathe manufacturers.
To ensure the accuracy of machining precision mechanical parts, the tool is the first. In the process of machining, it is generally necessary to use multiple tools. If the order of tool processing is not arranged well, the processing accuracy cannot be improved, and the processing efficiency cannot be guaranteed. When arranging the tool processing sequence, the general process principles of base surface first, surface first, hole first, rough first and then fine, first master and second time must be followed.
Base surface first is the basis of precision mechanical parts processing. CNC lathe manufacturers must first process the base surface to facilitate the processing of other surfaces. This process of the first base surface processing is the positioning benchmark for the next process, and it is not allowed to be careless. If the positioning datums of all processing operations have been determined, the approximate sequence of the entire process can also be reversed forward.
The machining accuracy of some precision mechanical parts may also require preprocessing of the blank. If the blank itself has high precision, accurate positioning, and sufficient machining allowance, there is no need for preprocessing, and it can be done directly in the machining center. This requires full consideration of the rough accuracy of the blank, and a full evaluation of the machining center process, whether it is completed in one process or needs to be divided into several processes.
The machining accuracy of precision mechanical parts must also consider the standard between the machined surface and the non-machined surface, which is similar to the milling process of CNC lathes. If it is the right or wrong machined surface, when processing the blank, it is necessary to leave an appropriate allowance on the non-machined surface. In this way, in the final processing process, it is possible to ensure that the standards of the processed surface and the non-processed surface meet the requirements of the customer's drawings. If there are also standard requirements for the pre-machined surface and the final machined surface, a machining allowance must also be reserved.
