What is a milling machine?
The milling machine is a machine tool with a wide range of uses. On the milling machine, it can process planes (horizontal planes, vertical planes), grooves (keyways, T-slots, dovetail grooves, etc.), gear parts (gears, spline shafts, sprockets), Spiral surface (thread, spiral groove) and various curved surfaces. In addition, it can also be used to process the surface and inner hole of the revolving body and cut off the work. When the milling machine is working, the workpiece is mounted on the worktable or the indexing head and other accessories, the milling cutter rotates as the main movement, and is supplemented by the feed motion of the worktable or the milling head, and the workpiece can obtain the required processing surface. Due to the multi-edge intermittent cutting, the productivity of the milling machine is high. Simply put, a milling machine can be a machine tool for milling, drilling and boring workpieces.

What is the difference between vertical milling machine, horizontal milling machine, universal milling machine and drilling and milling machine?
Compared with the horizontal milling machine, the main difference between the vertical milling machine and the horizontal milling machine is that the main shaft is arranged vertically. The milling cutter used for the vertical milling machine is relatively flexible and has a wider application range. End mills, machine clamps, drills, etc. can be used for keyway milling, plane milling, boring, etc. Horizontal milling machines can also use all the above tools, but they are not as convenient as vertical milling. The main feature is the use of hanger-enhanced tools (mainly three-sided edge milling cutters, sheet milling cutters, etc.), which can mill grooves, mill planes, and cut off. Horizontal milling machines generally can be equipped with an end milling head. Although the function and rigidity of this end milling head is not as strong as that of a vertical milling machine, it can do some end milling processing. This makes the overall function of the horizontal milling machine stronger than that of the vertical milling machine. Vertical milling machines cannot process workpieces suitable for horizontal milling, but the production efficiency is higher than that of horizontal milling machines.
The universal milling machine is suitable for using various bar milling cutters, circular milling cutters, and angle milling cutters to mill planes, bevels, grooves, etc. If you use universal milling heads, round tables, indexing heads and other milling machine accessories, you can expand the processing range of the machine tool. The machine tool has sufficient rigidity and power, has a strong processing capacity, can carry out high-speed and heavy-load cutting work, gear processing. The worktable of the universal milling machine can be rotated 45° to the left and right. When the worktable rotates at a certain angle and the indexing head attachment is used, various spiral surfaces can be processed.
The worktable of the drilling and milling machine can be moved vertically and horizontally, the main shaft is arranged vertically, usually a desktop, and the head can be raised and lowered. It has multiple cutting functions such as drilling, milling, boring, grinding, and tapping. The spindle box can rotate 90° left and right in the vertical plane, the worktable can rotate 45° left and right in the horizontal plane, and the worktable can automatically move longitudinally.
