The lathe is mainly used for machining various rotating surfaces and the end faces of the rotating bodies. Such as turning internal and external cylindrical surfaces, conical surfaces, ring grooves and forming rotary surfaces, turning end surfaces and various commonly used threads, equipped with process equipment can also process various special-shaped surfaces. It can also do drilling, reaming, reaming, knurling and other work on the lathe.

Milling machine A machine tool with a wide range of applications. On the milling machine, it can process planes (horizontal planes, vertical planes), grooves (key grooves, T-slots, dovetail grooves, etc.), split parts (gears, spline shafts, sprockets, spiral Shaped surface (thread, spiral groove) and various curved surfaces. In addition, it can also be used to process the surface and inner hole of the rotary body and perform cutting work. When the milling machine is working, the workpiece is installed on the table 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-cutting cutting, the productivity of the milling machine is high.

Planers are mainly divided into bull head planers, gantry planers, single-arm planers and specialized planers (such as planers for planing the edges of large steel plates, planing punches and planers for complex-shaped workpieces), etc. The ox head planer is named because the ram and the knife holder are shaped like a bull’s head. The planer is mounted on the ram holder for longitudinal reciprocating motion, and is mostly used to cut various planes and grooves. The gantry planer is named because it has a gantry frame structure composed of a top beam and a column. The workbench carries the workpiece to reciprocate linearly through the gantry frame. It is mostly used for machining large planes (especially long and narrow planes). To machine grooves or machine several small and medium parts at the same time. Large gantry planers are often attached with milling heads and grinding heads, etc., so that the work can be completed after one installation, such as planing, milling and grinding. The single-arm planer has a single column and a cantilever, and the worktable reciprocates longitudinally along the guide rail of the bed. It is mostly used for machining workpieces with a large width that does not need to be processed over the entire width. Spot welding

The slotting machine is mainly used for machining various planes (such as horizontal planes, vertical planes and inclined planes and various grooves, such as T-shaped grooves, dovetail grooves, V-shaped grooves, etc.) and straight-line forming surfaces. If equipped with profiling device, it can also process space curved surface, such as steam turbine impeller, spiral groove, etc. The tool structure of this type of machine tool is simple, and it does not cut when returning, so the productivity is low, and it is generally used for single-piece small batch production.

The boring machine is suitable for plane milling and hole machining of single-piece or small-batch parts in the machining workshop. The end of the spindle box is designed with a flat turntable radial tool holder, which can accurately boring large-sized holes and planes. In addition, drilling, reaming and thread machining are also possible.

Abrasive tools for grinding machines (grinding wheels, abrasive belts, whetstones, abrasives, etc.) are used as tools to machine the surface of the workpiece, and are collectively referred to as grinding machines. The grinder can process various surfaces, such as inner and outer cylindrical and conical surfaces, flat surfaces, gear tooth corridor surfaces, spiral surfaces and various forming surfaces. It can also sharpen tools and cut off. The process range is very wide. Because the grinding process easily obtains high machining accuracy and good surface quality, the grinding machine is mainly used for finishing parts, especially hardened steel parts and high hardness extraordinary materials.

The drilling machine has a versatile machine tool with a wide range of applications, such as drilling, reaming, reaming, countersinking and tapping of parts. When the radial arm drilling machine is equipped with technological equipment, it can also be used for boring; on the bench drill, it is equipped with a universal working table (MDT-180 type), and it can also mill the keyway.

Gear machining machine gears are the most commonly used transmission parts, there are spur, helical and herringbone cylindrical gears, spur and spiral bevel gears, worm gears and non-circular gears. The machine tool for machining the gear tooth surface is called gear machining machine tool.
