1. Selection of processed objects Before you determine the object to be purchased, you must first define the object to be processed. In general, parts with the following characteristics are suitable for machining in machining centers: Multi-process intensive type workpieces require many tools to be machined on one workpiece. Repetitive production of workpieces is suitable for single-piece, small-volume production. Small batches refer to 1-100 pieces, each batch is not much, but it needs to be repeated. In addition, even if the shape of the workpiece is different, it is a similar workpiece, and it is easy to realize the parts of the group processing process. Complex shape parts such as complex shape parts and aerospace parts can be processed into various shaped parts on the machining center by means of automatic programming technology. 2. Selection of machine specifications According to the determined size of the machined workpiece, the table size of the required machine tool and the stroke of the three linear coordinate systems are determined accordingly. The size of the table should be such that the workpiece can be smoothly clamped on the workpiece. The machining dimensions must be within each coordinate stroke. In addition, the space of the tool change and the interference of each coordinate interference zone should be considered. 3. Selection of machine tool accuracy According to the machining accuracy requirements of the workpiece, the user selects the machine tool with the corresponding accuracy grade, and the mass-produced parts may have a precision value of 1.5-2 times of the positioning accuracy. Ordinary machine tools batch processing 8-level precision workpieces, precision machine tool processing accuracy can reach 5-6, but there must be constant temperature and other process conditions, so the precision machine tools are strictly used and the price is high. 4. Selection of tool magazine capacity Manufacturers of machining centers usually have 2-3 different capacity magazines for the same type of machine. When selecting, the user can determine the required quantity according to the process analysis result of the workpiece being processed. Usually, one part is needed. The number of tools required in one setup determines the capacity of the magazine, because the tool needs to be rearranged when machining another part, otherwise the tool management is complicated and error-prone. 5. Machine selection function and selection of accessories When selecting a machining center (gantry milling machine), in addition to the basic functions and basic components, there are also functions and accessories that the user selects according to their own requirements, which are called selection functions and selection of accessories. With the development of numerical control technology, more and more content is available for selection, and the proportion of its constituent price in the mainframe is also increasing. Therefore, it is uneconomical to use a large number of attachments for unclear purposes. The so-called "prepared" Ordering guidance is essentially a waste. Therefore, a comprehensive analysis should be made at the time of selection, and long-term factors should be properly considered. The selection function is mainly for the numerical control system, but the price increase is not much, but it has many convenient functions for use, and should be properly configured. For accessories that can be shared by multiple machine tools, one machine can be considered for multi-purpose. But you must consider that the interface is generic.
