A milling machine is a machine tool that uses a milling cutter to process the flat surface of a workpiece. In addition to processing the flat surface of workpieces, milling machines can also process grooves and gears. Another point is that milling machines can also process workpieces with more complex surfaces. Therefore, compared with drilling machines, milling machine equipment has the characteristics of high processing efficiency, fast speed and simple operation. Workers who are not proficient in using milling machines do so because the cutting edge of the milling cutter is in a spiral shape. When the milling machine processes the workpiece, it generates a force that pulls the milling cutter outward. The force that the milling cutter pulls the drill bit is exactly opposite to the downward movement direction of the spindle, so the cutter will not fall off. If you want to use a drill bit instead of a milling machine for processing, you can first make a fixture to position the workpiece. Additionally, drill a hole in the spindle of the drilling machine to fix the milling cutter.
A drilling machine refers to a device that mainly uses drill bits to drill holes in workpieces. Under normal circumstances, the rotation of the drill bit is the main motion, and the axial movement of the drilling machine is the feed motion. The entire structure of the drilling machine is relatively simple, and its processing accuracy is very low. It can perform operations such as through holes and blind holes on workpieces. Additionally, it can change tools by itself and perform processing programs such as reaming and tapping.
The difference between a drilling machine and a milling machine:
The drilling machine has a simple structure and relatively low processing accuracy. It can drill through holes and blind holes. By changing special tools, it can also perform reaming, 锪 holes, boring holes or tapping and other processing. During the processing, the workpiece remains stationary while the tool moves. Align the center of the tool with the center of the hole and make the tool rotate (the main motion). The feature of a drilling machine is that the workpiece remains stationary while the tool rotates. A drilling machine is a versatile machine tool with wide applications, capable of performing operations such as drilling, reaming, boring, 锪 planing, and tapping on parts.
A milling machine is a widely used machine tool. On a milling machine, planes (horizontal planes, vertical planes), grooves (keyways, T-slots, dovetail grooves, etc.), toothed parts (gears, splined shafts, sprockets), helical surfaces (threads, helical grooves), and various curved surfaces can be processed. In addition, it can also be used for processing the surface and inner holes of rotating bodies and for cutting operations, etc. When the milling machine is in operation, the workpiece is mounted on the worktable or attachments such as the dividing head. The rotation of the milling cutter is the main motion, supplemented by the feed motion of the worktable or the milling head. Thus, the workpiece can obtain the required machined surface. Because it is multi-edge intermittent cutting, the productivity of the milling machine is relatively high. In simple terms, a milling machine is a type of machine tool that can perform milling, drilling and boring operations on workpieces. A drilling machine refers to a machine tool that mainly uses drill bits to process holes on workpieces. Generally, the rotation of the drill bit is the main motion, and the axial movement of the drill bit is the feed motion.
