Graph 1 auger cut 1 auger cut machine tool model various, size is differ. The sort of contemporary machine tool is infinite almost. Some machine tools are so small that some machine tools can install go up in workbench, some machine tools must want to build technical workshop ability to be accommodated greatly below. Some machine tools are quite simple, and the construction of some machine tools and operation are very complex. No matter the machine tool is big,be small, it is simple complex still, can divide it is 5 kinds big, 5 kinds of when this makes the metal shapes big kinds 5 namely basic methods. Get cutting is the treatment in the bore on sincere metal. The whirl that uses a kind to call twist drill broach. The machine tool that is used at bore calls drilling machine. Drilling machine also has a variety of model and norms. Outside dividing bore, drilling machine still can have other treatment. When bore, workpiece is fixed position clamp, fixed do not move; Broach one side rotates, get work at the same time (1) seeing a picture. 2 turning and bore hole general accuracy machine tool is the commonnest machine tool that is used at turning workpiece. Turning is the treatment that excises a metal from workpiece. While workpiece rotates, cutting tool cuts work or along workpiece turning (2) seeing a picture. Graph 2 turning pursue 3 bore hole graph 4 milling pursue 5 grinding bore hole is the treatment method that attend metallic work to already was gotten or makes further treatment. Boring hole on lathe is through Chan Ren cutting tool one side rotates to be finished to workpiece feed at the same time (3) seeing a picture. 3 milling milling is to use rotate the treatment of metal of cutting tool excision, this kind of cutting tool has many cutting where a thing can be put to best use, call milling cutter (4) seeing a picture. 4 grinding grinding is the grinding that uses a kind to call emery wheel annulus the treatment method that will excise a metal. Grinding has precision work to workpiece, the work measure after treatment accurate, surface is bright and clean. When grinding circle workpiece, workpiece one side rotates, face rotating emery wheel feed. Grind when making compressed work, workpiece goes back and forth between motion in gyral emery wheel dirty (5) seeing a picture. Grinding craft is commonly used have final precision work at the hard work to passing heat treatment, make its reach exact size. Dig of dig of 5 oxen head is cut, dig dig cuts dragon door to insert the plane that cuts these treatment to all use Chan Ren cutting tool to machine a future life to produce a nicety with slotting machine. We ought to know the distinction between shaping machine, double housing planer and slotting machine. When be being machined with shaping machine, workpiece provides feed to the knife, cutting tool is above workpiece make motion going there and back (6) seeing a picture. When dig of the door that use dragon is machined, cutting tool cuts work or to workpiece feed, workpiece makes motion going there and back below cutting tool (7) seeing a picture. Graph dig of 6 oxen head pursues dig of 7 dragon door pursues 8 insert cut treatment to insert cut treatment to be similar to treatment of bovine head dig. Slotting machine is actual it is vertical shaping machine, it is its only cutting tool is fluctuation motion. Insert when cutting treatment, workpiece has been made like cutting tool direction to motion, the basis is differred by the type of treatment workpiece, show sometimes straight, show arc sometimes (8) seeing a picture. Slotting machine namely vertical shaping machine, basically use at cutting the gear of certain type. Broaching machine is OK classify double housing planer this kind. Broach has many tooth. Broaching machine can be used at inside treatment, machine square aperture for example, also can use at extra work, machine plane or some kind of specific figure. CNC MillingCNC Machining
