Application knowledge of several types of commonly used machine tools

Lathes are mainly used to machine various rotating surfaces and end surfaces of rotating bodies. Such as turning inside and outside the cylindrical surface, conical surface, ring groove and forming surface, turning face and a variety of commonly used thread, equipped with processing equipment can also process a variety of special surface. Drilling, reaming, reaming, knurling, etc. can also be done on the lathe.

Milling machine A versatile machine tool that can machine flat surfaces (horizontal, vertical), grooves (keyways, T-slots, dovetails, etc.), toothed components (gears, spline shafts, sprockets, spirals) on a milling machine Shaped surface (threads, spiral grooves) and various curved surfaces.In addition, it can also be used to machine the surface of the rotor, bore machining, cutting work, etc. When the milling machine is working, the workpiece is mounted on the worktable or attachments such as the dividing head. The milling cutter rotates as the main movement, supplemented by the feed motion of the table or milling head, and the workpiece can obtain the required machining surface.Because it is multi-knife interrupted cutting, the productivity of the milling machine is higher.

The planer is mainly divided into planer, planer, single-planer and special planer (such as planing machine for edge of large steel plate, planing punch and planing machine with complex shape workpiece). The planer is named after the ram and the knife holder. The planer is mounted on the turret's knife holder for longitudinal reciprocation and is used to cut various planes and grooves. The planer is named because of a gantry type frame structure consisting of a top beam and a column. The worktable carries the workpiece through the gantry frame and reciprocates linearly. It is mostly used for machining large planes (especially long and narrow planes). Machining grooves or machining several small and medium-sized parts at the same time. Large planer planers often include milling heads and grinding heads. This allows workpieces to be planed, milled, and ground flat after a single installation. The single-arm planer has a single column and a cantilever. The table is longitudinally reciprocated along the guide rails of the bed, and is mostly used for processing workpieces having a large width without processing at the entire width. Spot welding

The 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.), and a straight molding surface. If equipped with a profiling device, it can also process spatial surfaces such as turbine impellers and spiral grooves. The tool structure of this kind 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 and small-batch production.

The boring machine is suitable for the machining workshop to carry out the flat milling and hole machining on the single-piece or small-batch production parts. The spindle box end is designed with a turret radial tool holder, which can accurately boring the larger size holes and planes. In addition, drilling, reaming and threading can also be performed.

Grinding machines Machine tools for grinding the workpiece surface using abrasives (grinding wheels, abrasive belts, whetstones, or abrasives, etc.) as tools are collectively referred to as grinding machines. Grinding machines can process a variety of surfaces, such as cylindrical and conical inner and outer surfaces, flat surfaces, gear tooth surfaces, spiral surfaces, and various molding surfaces. They can also sharpen cutting tools and perform cutting operations. Due to the high processing accuracy and good surface quality that can be easily obtained by grinding, the grinding machine is mainly used for finishing parts, especially the hard machining of steel parts and the finishing of extraordinary materials with high hardness.

The drilling machine has a versatile, versatile machine tool that can drill, ream, drill, ream, drill, and tap the part. When equipped with technological equipment on the radial drilling machine, it is also possible to carry out boring; the universal table (MDT-180 type) is equipped on the table drill, and the keyway can also be milled.

Gears Machine tool gears are the most commonly used transmission parts. They are cylindrical gears with straight teeth, helical teeth and herringbone teeth, bevel gears with straight teeth and arc teeth, worm gears and non-circular gears. The machine tool that processes gear tooth surfaces is called a gear machining machine.
