Selection criteria for CNC milling machines. According to the dimensions of the parts to be machined, the smaller-sized lifting table CNC milling machine is selected; the width of the working table is more than 400mm; it is most suitable for the processing of small and medium-sized parts and the generalized milling mission of the chaotic surface. The larger specifications such as gantry milling machine; The workbench is above 500 600mm; it is used to process the processing requirements of large-scale messy parts.
. According to the precision requirements of machined parts, China has developed the accuracy specification of CNC milling machine. In the meantime, the CNC vertical milling machine has a professional specification for the milling machine. The calibration accuracy of the linear motion coordinate is 0. 04/300mm; the repeat positioning accuracy is 0. 025mm; milling precision 0. 035mm. In fact; machine tool factory accuracy has an appropriate reserve; the tolerance of the national standard is about 20% contraction; thus; from the accuracy selection; the usual CNC milling machine Satisfied with the processing requirements of most parts. For parts with higher precision requirements, you should consider the use of fine CNC milling machines.
. According to the processing characteristics of the machined parts, select the steps of the frame where the machining part is frame-shaped plane or unequal height; then the CNC milling machine with the point---linear system can be the surface summary of the machining part; The shape resolution selects the system of two-coordinate linkage and three-coordinate linkage. It can also be based on the machining requirements of the parts; on the basis of the usual CNC milling machine; adding the numerical control indexing head or the numerical control reversing working table; at this time, the system of the machine tool is four-coordinate CNC system; able to process spiral grooves, blade parts, etc.
. According to the batch size or other requirements of the parts, the user can choose the special milling machine. If it is a small and medium batch and often repeats the production cycle regularly, then the CNC milling machine is very suitable; because many tools are prepared in the first batch. , programs, etc. can be stored and reused.
Thinking from a long time; the milling machine with high degree of automation replaces the usual milling machine; the trend of reducing the labor of laborers and improving productivity is inevitable.
Equipment for CNC Milling Machines The usual CNC milling machines are mechatronics; shipped from the manufacturer to the user; all are shipped; no crash packaging is required. Focus on the following aspects:
. After the unpacking machine is out of the box; first find the random skill file according to the packaging mark; check the attachments, things, spare parts, etc. according to the packing list in the skill file. If the contents of the box do not match the packing list; contact the manufacturer in time. Then Carefully read the clarification book; assist in the equipment operation according to the clarification book.
. Lifting according to the lifting diagram in the clarification book; put the wooden block or thick cloth in the proper orientation; avoid the steel wire rope to hurt the paint and the processing surface. During the lifting process; the center of gravity of the machine tool should be lowered as much as possible. It is not separated; the top of the electric cabinet usually has a lifting ring for lifting.
. Adjust the CNC milling machine; the main machine is shipped; the machine is adjusted before leaving the factory; the user should pay attention to the equipment: oil pressure adjustment, active smooth adjustment and key points to avoid the vertical tilting device of the lifting platform can work.
