What Is The Difference Between CNC Lathe Machining And CNC Milling Machining

CNC lathe machining and CNC milling machining are two common CNC machining methods, which have some differences in machining principles, applicable workpieces, and machining methods. Here are their main differences:
Processing principle:
CNC lathe machining: CNC lathes mainly achieve machining by rotating workpieces and cutting them with cutting tools. The movement path of the tool on the workpiece is along the axial direction of the workpiece, which can achieve machining of outer diameter, inner diameter, end face and other shapes.
Numerical control milling: Numerical control milling is mainly achieved through the rotation of the tool on the workpiece and the movement of the workpiece on the coordinate axis. The movement path of the tool on the workpiece is along the surface of the workpiece, which can achieve machining of flat, curved, and complex shapes.
Applicable workpieces:
CNC lathe machining: CNC lathes are suitable for machining long or axisymmetric workpieces, such as shaft parts, threads, gears, etc. It can achieve high-precision processing of outer and inner diameters, and has high processing efficiency.
Numerical control milling: Numerical control milling is suitable for processing workpieces with flat, curved, and complex shapes, such as flat parts, molds, carvings, etc. It can achieve multi axis simultaneous machining, with high machining accuracy and flexibility.
Processing method:
CNC lathe machining: CNC lathe machining mainly adopts rotary cutting method, and the relative motion between the tool and the workpiece is rotary motion, which can achieve machining of various outer and inner diameters. At the same time, CNC lathes can also perform operations such as turning, boring, and tapping.
Numerical control milling: Numerical control milling mainly adopts the cutting methods of rotation and linear movement. The relative motion between the tool and the workpiece is a combination of rotation and linear movement, which can achieve the machining of flat, curved, and complex shapes. Meanwhile, CNC milling can also perform operations such as drilling, reaming, and boring.
Programming and operation:
CNC lathe machining: The programming of CNC lathes mainly uses G code and M code for control, and the programming is relatively simple. Operators need to understand the structure and operating procedures of the lathe, and be able to perform operations such as tool installation, fixture adjustment, and workpiece clamping.
Numerical control milling: The programming of numerical control milling is relatively complex. In addition to G-code and M-code, it also requires operations such as tool radius compensation and tool path planning. Operators need to be familiar with the structure and operating procedures of milling machines, and be able to perform operations such as tool selection, fixture adjustment, and workpiece clamping.
In summary, there are certain differences between CNC lathe machining and CNC milling machining in terms of machining principles, applicable workpieces, and machining methods. Choosing the appropriate machining method based on specific workpiece requirements and processing needs can improve machining efficiency and quality.
