What is the difference between cnc and CNC lathe there?

2024-12-18

CNC (Computer Numerical Control) and CNC lathe are two important concepts in the field of machining and there are many differences between them.

Firstly, on a conceptual level, CNC is a type of control. It uses computer programmes to precisely control the movements of the machine tool, including tool trajectories, speeds, feeds, and many other parameters.CNC technology is like an intelligent brain that can efficiently command a variety of machine tools. And CNC lathe is a specific type of machine tool, which is mainly used for machining rotary body parts. Simply put, CNC lathe is a specific application carrier of CNC technology.

In terms of processing objects, CNC has a wider range of applications. Since CNC can control a variety of machine tools, such as milling machines, machining centres, EDM machines, etc., its processing object covers almost all shapes of mechanical parts. For example, CNC milling machines can process complex moulds, parts with curved surfaces and grooves; CNC machining centres are capable of milling, drilling, tapping and other kinds of machining on box-like parts. However, CNC lathe mainly focuses on processing rotary body parts, such as shafts and disc parts. For example, the transmission shaft of the car, the rotor of the motor and so on are the typical objects of CNC lathe processing.

From the processing mode, the machine tool under CNC control (milling machine, for example), the tool rotates at high speed, and through the movement of the table in the direction of X, Y and Z axes, the tool carries out cutting processing relative to the workpiece, and processes a variety of flat surfaces, curved surfaces and holes, and other shapes. While CNC lathe is the workpiece rotating around its own axis, the tool is in the tool holder of the lathe, and its movement in the axial (Z-axis) and radial (X-axis) directions is controlled by the CNC system to carry out operations such as turning, boring, grooving and thread turning.

In terms of programming, CNC programming is more complex in terms of what and how it is programmed because it involves multiple machine types. For example, for CNC five-axis linked machining centres, programming needs to consider the coordinated movement of multiple rotary and linear axes in order to machine complex spatial surfaces. CNC lathe programming is relatively simple and direct, mainly centred around the rotation of the workpiece and the movement of the tool in the two coordinate axes (X-axis and Z-axis) to write the program, focusing on controlling the depth, length and other parameters of the turning.

In addition, in terms of machine structure, CNC machine tools (milling machines, etc.) have parts such as the table, column, spindle box, etc. The structure is designed to facilitate the movement of the tool in multiple directions for machining. CNC lathes are mainly composed of bed, spindle box, tool holder, tailstock, etc., and their structure is designed around the rotation of the workpiece and the feed movement of the tool.

1. Functional aspectsCNC lathe: mainly used for processing rotary body parts, such as shafts and disc parts. It is processed around the workpiece rotating spindle. For example, processing a cylindrical shaft, CNC lathe can accurately turn the outer circle, inner hole, tapered surface, threads, and so on. The shape of its machining is mainly achieved by the linear or arc movement of the tool on the surface o...

Shape accuracy detection

In addition to dimensional accuracy, the shape accuracy of the parts cannot be ignored. Detect shape errors such as roundness, cylindricity, and flatness of parts using equipment such as roundness meters and contour meters. For example, when processing high-precision bearing rings, the accuracy of roundness and cylindricity directly affects the rotational accuracy and service life of the bearing.

Dimensional accuracy testing

Using advanced measuring tools and techniques, such as coordinate measuring instruments, optical imagers, etc., to accurately measure the dimensions of parts. For precision parts, dimensional tolerances are usually controlled at the micrometer level, so high-precision measuring equipment is required to ensure the accuracy of the test results. For example, when processing precision molds for mobile phone chi...
