CNC machine tools play a very important role in the manufacturing and processing industry. Their uses are mainly reflected in the following aspects:
1. Cutting materials
First of all, CNC machine tools have the advantage of multiple axes, so they can cut some parts during the manufacturing process. They can not only cut metals and plastics of regular shapes, but also program tool paths to achieve precision processing of parts of different models, sizes and shapes.
2. In addition to programming tool paths to achieve part cutting, CNC machine tools can also directly create and shape part prototypes. The principle is to control the movement and processing of machine tools through calculation and setting of system programming. Intelligent system programming can better meet the needs of different part processing and manufacturing. Fully automatic processing can be achieved through preset programming and command sequences.
3. Intelligent and convenient
Compared with traditional machine tools, the biggest advantage of CNC machine tools is that they can liberate labor and solve the shortcomings and limitations of manual control. Operators no longer operate through levers or handwheels, but use computers to perform precise calculations, which makes the processing of parts more accurate, improves work efficiency, and is more intelligent and convenient to use.
CNC machine tools are a very important type of automated processing equipment in the manufacturing industry. They are operated by computers executing pre-programmed controlled command sequences, providing efficient, convenient and precise production capabilities. What parts are suitable for CNC machine tools to process?
1. Most suitable for small and medium-sized batches of parts of various varieties
As the manufacturing cost of CNC machine tools gradually decreases, large-volume parts processing has already appeared both at home and abroad. When processing very small batches and single-piece production, it can also be selected if the program debugging time and tooling preparation time can be shortened.
2. Parts with high precision requirements
Since CNC machine tools have good rigidity, high manufacturing precision, accurate tool setting, and convenient dimensional compensation, they can process parts with high dimensional precision requirements.
3. Parts with small surface roughness values
When the materials, finishing allowances and tool angles of the workpiece and tool are constant, the surface roughness depends on the cutting speed and feed speed. Ordinary machine tools have a constant speed, and the cutting speed varies with different diameters. CNC machine tools have a constant linear speed cutting function, and the same linear speed can be used when turning end faces and external circles of different diameters to ensure that the surface roughness value is small and consistent. When machining surfaces with different surface roughness, a small feed speed is used for the surface with small roughness, and a larger feed speed is used for the surface with large roughness. The variability is very good, which is difficult to achieve on ordinary machine tools.
4. Parts with complex contours
Any plane curve can be approximated by a straight line or arc. CNC machine tools have arc interpolation functions and can process parts with various complex contours.
