In the face of many parts need to be processed, we should how to match their own needs of the machine tool, how to choose their own CNC milling machine?
1. The size of the main specifications of CNC milling machine should be compatible with the profile size of the workpiece. That is, small workpiece should choose small size of machine tool processing, and large workpiece is selected large size of machine tool processing so as to achieve the reasonable use of equipment.
2. The structure of CNC milling machine depends on the influence of factors such as machine specifications and size, the weight of the workpiece.
3. CNC milling machine work accuracy and process requirements of the processing accuracy. Select machine tools according to the machining accuracy requirements of parts, such as rough machining process with low accuracy requirements, low precision machine tools should be selected, and high precision finishing process should be selected.
4. The power and stiffness of the machine tool as well as the range of maneuvering should be adapted to the nature of the process and the most appropriate cutting dosage. If the rough machining process to remove the blank allowance is large, the cutting allowance is selected large, it requires the machine tool to have large power and better stiffness.
5. Convenient clamping, simple fixture structure is also a factor to consider when choosing CNC equipment. Choose to use horizontal CNC milling machine, or choose vertical CNC milling machine, will directly affect the selection of fixture structure and processing coordinate system, directly related to the degree of NC programming and NC machining reliability. Should notice is, should make full use of the function of numerical control machine tool when choosing numerical control milling machine, undertake reasonable development according to need, in order to enlarge the function of numerical control machine tool, satisfy the need of the product. Then, according to the choice of CNC milling machine, further optimize the CNC processing scheme and process route according to the need to adjust the content of the process.
There is also a situation many enterprise bosses feel that small CNC machine tools can only process small parts of the product, buy a bigger machine tool back, the size of parts can be processed products. This is the case for that.
