The main purpose of common machine tools
lathes are mainly used for processing various rotating surfaces and end faces of rotating bodies. Such as turning inner and outer cylindrical surfaces, conical surfaces, ring grooves and forming revolving surfaces, turning end faces and various commonly used threads, and processing various special-shaped surfaces with process equipment. Drilling, reaming, reaming, knurling, etc. can also be done on the lathe.
Milling machine is a widely used machine tool. On the milling machine, it can process planes (horizontal planes, vertical planes), grooves (keyways, T-slots, dovetail grooves, etc.), and gear parts (gears, spline shafts, sprockets, spirals). Shaped surfaces (threads, spiral grooves) and various curved surfaces. In addition, it can also be used to process the surface of the revolving body, the inner hole and the cutting work. When the milling machine is working, the workpiece is installed on the worktable or the indexing head and other accessories. The rotation of the milling cutter is the main movement, supplemented by the feed movement of the table or the milling head, the workpiece can obtain the required machining surface. Because of the multi-cut intermittent cutting, the productivity of the milling machine is high.
Planer
Slotting machine is mainly used for processing various planes (such as horizontal plane, vertical plane and inclined plane and various grooves, such as T-shaped groove, dovetail groove, V-shaped groove, etc.), linear molding surface. If equipped with a profiling device, it can also process spatial curved surfaces, such as steam turbine impellers, spiral grooves, etc. The tool structure of this type of machine tool is simple and does not cut during the return stroke, so the productivity is low, and it is generally used for single-piece small batch production.
boring machine is suitable for plane milling and hole machining of single or small batch production parts in machining workshops. The end of the spindle box is designed with a flat rotary tool post, which can accurately boring larger holes and planes. In addition, drilling, reaming and threading can be performed.
Grinder Machine tools that use abrasive tools (grinding wheels, belts, oilstone or abrasives, etc.) as tools to cut the surface of the workpiece are collectively called grinders. The grinder can process a variety of surfaces, such as internal and external cylindrical and conical surfaces, flat surfaces, gear tooth profile surfaces, spiral surfaces and various shaped surfaces, etc. It can also sharpen tools and cut off, etc., with a wide range of processes. Since grinding is easy to obtain high machining accuracy and good surface quality, the grinder is mainly used for the finishing of parts, especially the finishing of hardened steel parts and high-hardness special materials.
Drilling machine It is a versatile machine tool with a wide range of uses, which can perform drilling, reaming, reaming, countersinking and tapping of parts. When the radial drilling machine is equipped with process equipment, it can also be used for boring; when the bench drill is equipped with a universal table (MDT-180), it can also mill keyways.
