Milling machine
The milling machine mainly refers to the machine tool that uses the milling cutter to process various surfaces of the workpiece. Usually the rotary motion of the milling cutter is the main motion, and the movement of the workpiece and the milling cutter is the feed motion. It can process planes, grooves, and can also process various surfaces, gears, etc.
A milling machine is a machine that uses a milling cutter to mill the workpiece. In addition to milling plane, groove, gear teeth, thread and spline shaft, milling machine can also process more complex profile, higher efficiency than planer. It is widely used in machinery manufacturing and repair departments.
Milling machine is a widely used machine tool, can be processed plane (horizontal plane, vertical plane), groove (keyway, T-groove, dovetail groove, etc.), split tooth parts (gear, spline shaft, sprocket), spiral surface (thread, spiral groove) and various surfaces. In addition, it can also be used for the surface of the rotary body, the inner hole processing and cutting work. When the milling machine is working, the workpiece is installed on the workbench or the indexing head , the milling cutter rotation is the main movement, supplemented by the feed movement of the workbench or the milling head, the workpiece can obtain the required machining surface. Because of the multi-edge intermittent cutting, the productivity of the milling machine is higher. In simple terms, a milling machine is a machine tool that can mill, drill and boring the workpiece.
Main classification: According to the layout form and scope of application to be distinguished
1.Lifting table milling machine: universal, horizontal and vertical, mainly used for processing small and medium-sized parts, the most widely used.
2. Planomiller: including planer type milling-boring machine, planer milling machine and double column milling machine, are used for processing large parts.
3. Single-column milling machine and single-arm milling machine: the horizontal milling head of the former can move along the guide rail of the column, and the table can be fed lengthwise; The end milling head of the latter can be moved horizontally along the cantilever guide, and the cantilever can also be adjusted in height along the column guide. Both are used for machining large parts.
4. Table non-lifting milling machine: there are rectangular work table and round work table, which is a medium size milling machine between the lifting table milling machine and the gantry milling machine. Its vertical movement is completed by lifting the milling head on the column.
5. Instrument milling machine: a small lifting table milling machine for machining instruments and other small parts.
6. Tool milling machine: used for mold and tool manufacturing, equipped with a variety of accessories such as end milling head, universal Angle table and plug, but also for drilling, boring and insert machining.
7. Other milling machines: such as keyway milling machine, CAM milling machine, crankshaft milling machine, roll journal milling machine and square ingot milling machine, etc., are special milling machines manufactured for processing the corresponding workpiece.
