CNC milling machine four selection tips

According to the size of the parts being processed

The smaller size of the lifting table CNC milling machine, the table width of more than 400mm, it is most suitable for the processing of small and medium parts and the contour surface contour milling tasks. Larger specifications, such as gantry milling machines, with tables above 500-600 mm, are used to solve the processing needs of large and complex parts.

According to the precision requirements of machined parts

China has established the precision standards for CNC milling machines, among which the CNC vertical milling machine has professional standards for lifting and milling machines. The standard stipulates that the positioning accuracy of its linear motion coordinates is 0.04/300mm, the repeat positioning accuracy is 0.025mm, and the precision of milling is 0.035mm. In fact, the precision of the machine tool has a considerable reserve, which is about 20 times less than the national standard. Therefore, from the perspective of precision selection, the general CNC milling machine can meet the processing needs of most parts. For parts with high precision requirements, you should consider using a precision CNC milling machine.

According to the processing characteristics of the processing parts to choose

For processing parts that are frame-shaped planes or unequal height steps, use a CNC milling machine with a point-line system. If the machined part is a curved surface profile, a system that selects two coordinate linkages and three coordinate linkages should be selected based on the geometry of the surface.

Also based on the part processing requirements, on the basis of the general CNC milling machine, increase the number of CNC indexing head or CNC rotary table, then the system of the machine tool for the four-axis CNC system, can process spiral groove, blade parts and so on.

Choose according to part's batch or other requirements

For large quantities, users can use special milling machines. If it is a medium-small batch and it is often periodically repetitively put into production, then the use of a CNC milling machine is very appropriate, because the first batch of multi-tools, programs, etc. can be stored for reuse. In the long run, replacing the milling machine with a high degree of automation in the milling machine, the trend of reducing laborers' productivity and increasing productivity is inevitable.
