The classification of CNC machining technology can be specifically distinguished from multiple dimensions such as machining methods, process uses, and control methods.
1. Classification based on machining technology characteristics
Rotary cutting: The core is to process rotating parts, covering a variety of turning processes such as external turning, internal turning, end face finishing, and thread forming.
Plane and contour milling: Focus on the processing of geometric shapes such as planes, grooves, and complex curved surfaces. The technology covers a variety of milling strategies such as plane milling, end milling, and profile milling.
Hole machining technology: Specially handles the processing needs of various types of holes, including drilling, reaming, fine reaming, boring, and other processes to meet the requirements of different apertures and precision.
Surface finishing: For parts with strict requirements on surface roughness, grinding, polishing and other technical means are used, such as precision machining of bearings and gears.
Special and non-traditional processing: Including laser cutting and welding, ultrasonic processing, and water cutting, these technologies do not rely on traditional mechanical cutting, but use energy beams or fluid power for processing.
2. Classification based on application process category
Metal direct cutting machine tools: focus on direct removal of metal materials, covering a variety of machine tool types such as lathes, drilling machines, milling machines, grinders, etc.
Metal plastic forming machine tools: use external forces such as pressure and impact to plastically deform metal to form the required shape, such as presses, bending machines, etc.
Special and high-precision processing machine tools: for processing tasks with special materials or high-precision requirements, such as laser cutting, EDM, wire cutting and other special processing machine tools.
3. Classification from the perspective of control strategy and accuracy
Point control machine tools: This type of machine tool only focuses on the precise positioning of the tool at each point in space, and does not involve the movement trajectory between them.
Linear control machine tools: on the basis of point control, further ensure that the tool moves accurately along a straight line trajectory between two points.
Multi-axis contour control machine tools: the highest level of control mode, which can simultaneously control the movement of multiple coordinate axes to achieve precise processing of complex three-dimensional shapes, suitable for the production of high-precision and complex parts.
