Milling Machine is a kind of processing equipment and a kind of machine tool. In order to have a better understanding of milling machine, Xiao Bian specially collected some knowledge about milling machine on the Internet, the types, safety rules and maintenance of milling cutters, through the introduction of these three aspects, hope to be able to give some guidance or help to friends who want to buy CNC milling machines, as follows. I. 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 and can be divided into straight teeth and spiral teeth according to the tooth shape. According to the number of teeth, there are two types: coarse teeth and fine teeth. Spiral tooth coarse tooth milling cutter has few teeth, high cutter tooth strength and large chip holding space, and is suitable for rough machining; Fine tooth milling cutter is suitable for finishing. Face milling cutter: used for vertical milling machine, end face milling machine or gantry milling machine. There are cutter teeth on the end face and circumference, as well as coarse teeth and fine teeth. Its structure has three types: integral type, inlay type and indexable type. End Mill: it is used to process grooves, step surfaces, etc. The cutter teeth are on the circumference and end face, and cannot be fed along the axial direction when working. When there are end teeth passing through the center on the end mill, axial feed can be made. Three-sided edge milling cutter: used to process various grooves and step surfaces, with cutter teeth on both sides and circumference. Angle milling cutter: used for milling grooves with a certain angle, there are two kinds of single-angle milling cutters and double-angle milling cutters. II. Safety Rules 1. For loading and unloading workpieces, the cutter must be removed, and the cutting center head and hands must not approach the milling surface. 2. When using the milling machine to set the knife, it must be slow or hand-cranked. It is not allowed to fast forward. When the knife is passed, it is not allowed to stop. 3. Pay attention to whether the milling machine handle will hit people when quickly advancing and retreating the knife. 4. The feed is not allowed to be too fast, and it is not allowed to change suddenly. The milling machine limit block should be adjusted. 5. The milling machine must be stopped for up and down and measuring workpieces, adjusting cutting tools and fastening and changing speed. 6. Disassembly end mill. The surface should be pad Wood split ping xian dao flip nut hard shall not be too. 7. It is strictly forbidden to touch or use cotton yarn to wipe the rotating parts and knives. It is forbidden to use the hand to support the cutter. Third, maintenance 1. Clean (1)Disassemble and clean all oil felt pads; (2) Wipe each sliding surface and guide surface, wipe the workbench and horizontal, lifting screw, wipe the tool drive mechanism and tool holder; (3)Wipe the dead corners of each part. 2. Lubrication (1)Each oil hole is clean and smooth and filled with lubricating oil; (2) Add lubricating oil to each guide surface, sliding surface and lead screw; (3) Check the oil box and oil level of the transmission mechanism, and add oil to the elevation position. 3. Anti-corrosion (1) Remove the rust of each part, protect the paint surface, and do not collide; (2) Stop using, spare equipment Guide surface, sliding screw handwheel and other exposed parts that are easy to rust are oiled to prevent corrosion.
