From the design drawings of parts to the qualified delivery of finished parts, a series of factors such as the arrangement of the process route of metal parts, the selection of machine tools, the selection of cutting tools, and the positioning and clamping of parts can be considered. Avoid quality problems that may arise due to poorly considered process plans. Metal cutting machine tools have a wide range of process performance and can be used for linear cylinders, oblique cylinders, arcs, various threads, worms and other complex workpieces. They have various functions of linear interpolation and arc interpolation, and can be used in complex parts. achieved good economic results. The following is a brief introduction to the common metal cutting machine tool equipment:

1. Lathe equipment

Lathes are mainly used for various rotary surfaces and the end faces of rotary bodies. Such as turning internal and external cylindrical surfaces, conical surfaces, annular grooves and forming rotating surfaces, turning end surfaces and various commonly used threads. Equipped with process equipment, it can also be used for various special-shaped surfaces. Drilling, reaming, reaming, knurling, etc. can also be done on the lathe.

2. Milling machine equipment

Milling machine is a widely used machine tool. It can be used for flat surfaces (horizontal planes, vertical planes) and divided gear parts (gears, spline shafts, Sprockets, spiral surface threads, spiral grooves) and various curved surfaces. In addition, it can also be used for processes such as cutting the surface and inner hole of the rotary body. The workpiece is mounted on the operating table or an accessory such as an indexing head. The rotation of the milling cutter is the main movement, supplemented by the feed movement of the operating table or milling head, so that the workpiece can obtain the required surface. Because it is multi-tool intermittent cutting, the milling machine is more efficient.

3. Planer equipment

Planers are mainly divided into bull-head planers, gantry planers, single-arm planers and specialized planers (such as edge planers and planers for planing the edges of large steel plates). punches and planing machines for complex-shaped workpieces), etc. The gantry planer is named after a gantry frame structure composed of top beams and columns. The operating table carries the workpiece through the gantry frame for linear reciprocating motion. It is mostly used for large planes (especially long and narrow planes). It is also used for Grooves or flat surfaces to complete several small and medium parts at the same time. Large gantry planers are often equipped with components such as milling heads and grinding heads, so that the workpiece can be planed, milled and ground in one installation. The single-arm planer has a single column and a cantilever, and the operating table reciprocates longitudinally along the bed guide rail. It is mostly used for workpieces with a large width that do not need to cover the entire width.

IV. Slotting machine equipment

Slotting machines are mainly used for various planes (such as horizontal planes, vertical planes and inclined planes and various shaped grooves, dovetail grooves, etc.) and linear forming surfaces. If equipped with a profiling device, it can also be used for 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. It is generally used for single and small batch workpieces.

5. Boring machine equipment

The boring machine is suitable for machine shops to perform surface milling and hole system processing on single or small batch parts. The end of the spindle box is designed with a flat rotating disc radial Tool holder, capable of accurately boring larger holes and flat surfaces. Drilling, reaming and threading can also be performed.

6. Grinding machine equipment

Grinders are machine tools that use abrasive tools (grinding wheels, abrasive belts, whetstones or abrasives, etc.) as tools to cut the surface of workpieces, collectively called grinders. The grinder can be used on various surfaces, such as internal and external cylindrical and conical surfaces, flat surfaces, gear corridor surfaces, spiral surfaces and various forming surfaces. It can also sharpen tools and cut off, etc. The process range is very wide. Since grinding can easily achieve high precision and good surface quality, grinding machines are mainly used for precision machining of parts, especially for hardened steel parts and high-hardness special materials.

7. Drilling machine equipment

Drilling machines are versatile machine tools with a wide range of uses. They can drill, ream, countersink, and tap parts on parts. When the radial drilling machine is equipped with process equipment, it can also be bored; when the bench drill is equipped with a universal operating table, it can also mill keyways.

8. Tooth profile equipment

Tooth profile cutting machine gears are the most commonly used transmission parts, including spur gears, helical gears and herringbone gears, spur gears and arc gears Bevel gears, worm gears and non-circular gears, etc. Machine tools used for cutting surfaces of gear teeth are called gear machine tools.
