1. Selected by the processed object
Before determining the purchase object, we must first clearly prepare the processing object. Generally speaking, parts with the following characteristics are suitable for processing in the processing center: Multi -work -type intensive workpieces refer to many tools for processing on one workpiece. Repeated production -type workpieces are suitable for processing single -piece small batch production. Small batches refer to 1-100 pieces, each batch is not large, but it needs to be repeatedly produced. In addition, even if the shape and size of the workpiece is different, it is similar to the workpiece, which is easy to achieve parts of the processing process. Complex -shaped parts of parts, aviation parts, and other complex shape workpieces can process various alien parts on the processing center with the help of automatic program compilation technology.
2. Selection of machine tool specifications
According to the size of the determined processing workpiece, the workbench size and the three straight coordinate systems corresponding to the required machine tool should be determined accordingly. Metal processing WeChat, the content is good and worthy of attention. The size of the workbench should ensure that the workpiece can be successfully installed on the workpiece on it, and the processing size must be within each coordinate itinerary. In addition, the restrictions of the sword space and the coordinate interference areas must be considered.
3. Selection of machine tool accuracy
According to the processing accuracy requirements of the workpiece, the actual processing accuracy value of the actual processing accuracy may be 1.5-2 times the accuracy of the accuracy. General machine tools are processed 8-level precision workpieces in batches, and the processing accuracy of precision machine tools can reach level 5-6, but there must be process conditions such as constant temperature, so the precision machine tools are strictly used and the price is high.
4. Selection of the blade capacity
The manufacturer of the processing center usually has 2-3 different capacity knife libraries for the same specifications of machine tools. When the user is selected, it can determine the required quantity based on the process analysis results of the processing workpiece. Generally, one part is required for one part. The number of tools required in a clamp to determine the capacity of the blade, because when changing another part to process, the tool needs to be re -arranged, otherwise the tool management will be complicated and easy to make errors.
