First of all, a brief introduction.

A machine tool for cutting metal. Equipped with rod-shaped or disc-shaped multi-edge cutter, used for machining planes, curved surfaces and various grooves. When working, the cutter rotates and the workpiece moves to contact with the cutter. There are many kinds, such as vertical milling machine, horizontal milling machine, gantry milling machine, copying milling machine and universal milling machine.

Second, explain

1. Milling machine mainly refers to the machine tool that uses milling cutter to process various surfaces of workpiece. Usually, the rotary motion of the milling cutter is the main motion, and the motion of the workpiece and the milling cutter is the feed motion. Can process planes and grooves, as well as various curved surfaces and gears.

2. Milling machine is a machine tool for milling workpieces with milling cutter. Milling machines can not only mill planes, grooves, gear teeth, threads and spline shafts, but also process more complex contours, with higher efficiency than planers, and are widely used in machinery manufacturing and repair departments. Milling machine is a widely used machine tool, which can process planes (horizontal plane and vertical plane).

Third, safety rules.

1, when loading and unloading the workpiece, you must remove the cutter and the cutter head, and keep your hands away from the milling surface; When Xú Zhēng milling machine is used for tool alignment, it is necessary to feed slowly or manually, and it is not allowed to fast forward, and it is not allowed to stop when cutting. Pay attention to whether the handle of Xú Zhēng milling machine will hit people when it advances and retreats quickly; Don't feed too fast, don't change speed suddenly, and adjust the limit of Xú Zhēng milling machine.

2, up and down and measuring the workpiece, adjust the cutting tool, fastening speed, must stop Xu Zheng milling machine; Dismantle the end milling cutter, the workbench should be padded with wooden boards, and the milling cutter nut should be flattened, and don't use too much force; It is forbidden to touch or wipe rotating parts and tools with cotton yarn, and it is forbidden to hold the cutter head by hand.

3. Under normal circumstances, a chuck can only hold one workpiece at a time. Because a chuck clamps multiple workpieces at a time, even if it is tightly clamped, the force is great during rough feeding, and it is easy for two workpieces to slide between them, resulting in accidents such as workpiece flying out, knife breaking and personal injury.
