With the development of modern industry, CNC machine tools have gradually been widely used, among which CNC vertical lathes and milling machines are one of the most basic CNC machine tools. Although both can process workpieces, their working principles, structures and application scenarios are different.
First of all, a CNC vertical lathe is a machine tool that processes workpieces by rotating tools. This machine tool is mainly used to process rotationally symmetrical workpieces, so it is widely used in automobile manufacturing, mold manufacturing, aerospace, bearing manufacturing and other industries. In addition, CNC vertical lathes are characterized by high automation and high precision, and can achieve efficient processing processes and excellent processing effects through program control.
A CNC milling machine, meanwhile, is a machine tool that processes workpieces by moving a worktable. Milling machines are mainly used to process complex workpieces such as planes, convex and concave surfaces, gears and curves, and are therefore widely used in fields such as machinery manufacturing, mold manufacturing and aerospace. CNC milling machines have the characteristics of high automation, high production efficiency and high processing accuracy, and can adapt to different processing needs and complex processing tasks.
Secondly, the structures of CNC vertical lathes and milling machines are also different. CNC vertical lathe mainly consists of spindle, tool holder, workbench, feed system and control system. The spindle drives the tool holder to rotate, and the tool holder can also move up and down and in a straight line to achieve cutting operations. The workbench is used to clamp the workpiece, and the feed system controls the movement of the workbench along the tool holder.
The CNC milling machine is mainly composed of a spindle, a workbench, a feed system and a control system. The spindle drives the tool to rotate, and the workbench can move horizontally and vertically to accommodate workpieces of different shapes and sizes. The feeding system controls the movement of the workbench along the three directions of X, Y, and Z to achieve processing operations.
In general, although CNC vertical lathes and milling machines are CNC machine tools, their principles, structures and application scenarios are different. According to different processing requirements and workpiece shapes, choosing the appropriate CNC machine tool plays a vital role in improving production efficiency and processing quality.
