CNC milling machines, CNC lathes, and machining centers are all machine tools, but there are differences between them. CNC milling machine is a machine tool that uses milling cutters to mill workpieces. CNC lathes mainly use turning tools to turn rotating workpieces. The machining center is a CNC machine tool with a tool magazine and an automatic tool changer, which can process more than ordinary CNC milling machines process more complex profiles.

The difference between CNC milling machine and CNC lathe

Different works

The workpiece is on the spindle of the CNC lathe, and the tool is on the tool holder and moves linearly in the XZ plane.

The spindle of the CNC milling machine is the milling cutter, and the workpiece is on the worktable. When the milling machine is working, the workpiece is mounted on the worktable or on the accessories such as the indexing head. The rotation of the milling cutter is the main movement, supplemented by the feed of the worktable or the milling head. Movement, the workpiece can obtain the required machining surface. Due to the multi-tool intermittent cutting, the productivity of CNC milling machines is high.

Different uses

The parts processed by CNC lathes are rotating bodies, such as shafts, holes, undercuts, internal and external threads, etc. Drills, reamers, reamers, taps, dies and knurling tools can also be used for corresponding processing on CNC lathes. CNC lathes are mainly used for machining shafts, discs, sleeves and other workpieces with surfaces of revolution.

CNC milling machine can process planes, grooves, and various curved surfaces, gears, etc. In addition to milling planes, grooves, gear teeth, threads and spline shafts, CNC milling machines can also process more complex profiles, which are more efficient than planers. In addition, they can also be used for surface, inner hole machining and cutting of rotary bodies. work etc.

Summary: CNC milling machine is a machine tool that uses milling cutters to mill workpieces. CNC lathes mainly use turning tools to turn rotating workpieces. Users should choose a machine tool that suits them according to their actual situation.

The difference between CNC milling machine and machining center

The CNC milling machine has only three axes, and the CNC machining center can be four-axis or five-axis linkage. Generally, the CNC milling machine has three coordinates, namely X, Y, Z, plus a spindle. The machining center mainly refers to the machine tool with more than four coordinates. The machining center can process more complex profiles than ordinary CNC milling machines.

The machining center has an additional tool magazine and tool change system, while the CNC milling machine does not have a tool magazine, and the tool change is performed manually during the processing. CNC milling machines are generally used to mill relatively simple surfaces, and can also mill relatively shallow holes. The machining center itself has a tool magazine, and the tool is automatically changed by the manipulator. A CNC milling machine is equipped with a tool magazine to become a machining center. A tool magazine can hold many knives. It depends on the actual workpiece types to be processed, including face milling cutters, end mills, keyway milling cutters, ball cutters, boring cutters, and thread cutters. And so on, it has the function of automatic tool exchange. By installing tools for different purposes in the tool magazine, the machining tools on the spindle can be changed through the automatic tool changer in one clamping to realize drilling, boring, reaming, tapping and grooving. And many other processing functions to facilitate parts processing!

The machining center is a CNC machine tool with a tool magazine and an automatic tool changer. It combines the functions of a CNC milling machine, a CNC boring machine, and a CNC drilling machine with powerful functions.
