Talking about the types of milling cutters, safety rules and maintenance of milling machines

A milling machine is a kind of processing equipment and a kind of machine tool. In order to have a better understanding of the milling machine, the editor deliberately collected some knowledge about the milling machine on the Internet, the types of milling cutters, safety rules and maintenance, through these three aspects I hope to give some guidance or help to friends who want to buy a CNC milling machine. The introduction is as follows. 1. Types of milling cutters The types of milling cutters are: Cylindrical milling cutters: used to process planes on horizontal milling machines. The cutter teeth are distributed on the circumference of the milling cutter. According to the tooth shape, they are divided into straight teeth and spiral teeth. According to the number of teeth, there are two types: coarse teeth and fine teeth. The helical coarse-tooth milling cutter has fewer teeth, high tooth strength and large chip holding space, which is suitable for rough machining; fine-tooth milling cutters are suitable for fine machining. Face milling cutter: used for vertical milling machine, face milling machine or gantry milling machine. There are cutter teeth on the end face and the circumference, and there are also coarse and fine teeth. Its structure has three types: integral type, insert type and indexable type. End milling cutter: used for processing grooves and step surfaces, etc. The cutter teeth are on the circumference and end surface, and cannot be fed along the axial direction when working. When the end mill has end teeth passing through the center, it can feed axially. Three-sided edge milling cutter: used for processing various grooves and stepped surfaces, with teeth on both sides and circumference. Angle milling cutter: It is used for milling grooves at a certain angle. There are two types of single-angle and double-angle cutters. 2. Safety rules 1. When loading and unloading the workpiece, the tool must be removed, and the cutting head and hands must not approach the milling surface. 2. When using the milling machine to set the tool, it must be slow forward or hand cranked, fast forward is not allowed, and the tool is not allowed to stop when moving the tool. 3. Pay attention to whether the handle of the milling machine will hit people when fast forwarding and retreating the tool. 4. The feed is not allowed to be too fast, and it is not allowed to change speed suddenly, and the limit stop of the milling machine should be adjusted well. 5. The milling machine must be stopped for up and down, measuring the workpiece, adjusting the tool, and tightening the speed change. 6. When disassembling the end mill, the work surface should be padded with wood, and the nut should be flattened, and the force should not be too strong. 7. It is strictly forbidden to touch or wipe the rotating parts and knives with cotton yarn, and it is forbidden to remove the knife tray by hand. 3. Maintenance 1. Cleaning (1) Disassemble and clean the various oil felt pads; (2) Wipe the sliding surfaces and guide rail surfaces, wipe the workbench and the horizontal, the lifting screw, wipe the knife drive mechanism and the knife holder; (3) Wipe the parts Dead ends. 2. Lubrication (1) Each oil hole is clean and unobstructed and filled with lubricating oil; (2) Each guide rail surface, sliding surface and each screw rod are filled with lubricating oil; (3) Check the oil tank and oil surface of the transmission mechanism, and add oil to Elevation position. 3. Anti-corrosion (1) Remove the rust of each part and protect the painted surface from collision; (2) Stop use, spare equipment guide rail surface, sliding screw handwheel and other exposed parts that are easy to rust are painted with oil for anti-corrosion.
