Processing and scope of conventional machine tools

Machine tools are becoming more popular as the market for machining grows.

The machine tools of the country can be divided according to their processing methods and tools. There are 11 types: lathes; drilling machines; boring machines; grinding machines; gear machines; threading machines and milling machines.

There are seven types of boring machines, grinders and lathes.

Drilling machine

This boring machine can be used for flat milling or hole making in small batches of single or multiple production parts. An end of the headstock has a radial tool holder that is flat rotating and can drill large holes or holes. , apartment.

There are two types of boring machines: CNC boring machines and CNC Jig boring machines. These machines can be divided vertically or horizontally. The drilling machine's control method is point-and-line, which is for processing boxes-shaped parts. Manual tool change is necessary. The jig boring machines control mode is point-and-line, which is for processing parts with high holes distance requirements and requires manual tool changing.

A machine that uses abrasive material (grinding wheels or abrasive belts), is also known as an oil stone or abrasive machine. A grinder is a tool that cuts the surface of a workpiece.

Processing and scope of conventional machine tools

According to the nature of the process, it is divided into surface grinder, internal and external cylindrical grinder, universal grinder, centerless grinder and special grinder. Inspection methods: point, line and contour.

It is used mostly for rough and fine grinding of the plan, mirror grinding, shape grinder after modification of the grinder wheel, etc. The centerless grinder doesn't require any pre-turning to straighten the grind, centerless shape grinder; special grinders include a grinder, crank grinder and camshaft grinder.

Grinding machines are used primarily for finishing workpieces that require high precision and excellent surface quality.


Lathes are used primarily to process various rotating surfaces and ends from rotation bodies. The equipment can be divided into vertical and horizontal types.

Among them, the control method of the horizontal lathe chuck is point position and straight line, which is used to process small disc parts, and uses a square tool post or turret; upper horizontal lathe control method - contour, which is used to process discs, shafts Type of parts, the bed can be divided into horizontal, vertical and inclined, using a square tool post or rotary tool magazine.

Contour is the control mode for the CNC vertical lathe. This is used to machine large portions of the continuous control disc and also uses a tool holder.


The planer is used primarily for processing different planes (such horizontal, vertical, inclined, and inclined planes) and various grooves like T-grooves dovetail grooves, V grooves, V-grooves etc. You can also use the planer to create linear shaping surfaces. .

It can process spatially curved surfaces like spiral grooves and steam turbine impellers if it has a profiling device. This machine's tool structure is simple and does not cut on the return journey. It is often used for small batches and piece production.

Milling machine

Multipurpose machine capable of machine planes (horizontal and vertical), grooves (keyways (T-slots, dovetail grooves), etc. ), gear parts (gears and splined shafts. Spiral surface (thread), spiral groove, and other curved surfaces. It can also be used to machine and cut the outer hole and surface of the rotation body.

The workpiece is placed on the table or other accessories while the milling machine runs. Rotation is the main movement of a cutter, which is complemented by the milling head or work table feed movements. The workpiece can then achieve the desired processing surface. The milling machine's high productivity is due to its multi-tool intermittent cutter.

Milling machines can be divided into vertical and portal. CNC router control mode: bit position, straight line, contour (multi-axis linkage), milling, shaping (drilling and tapping are also available), and manual tool change.

CNC portal milling machine control modes: bit position (straight line), contour (multi-axis linking), which can be used to process large and complex parts as well as manual tool changes.

There is also a CNC milling and profiling machine available on the market. This can be divided into horizontal and vertical. Contour (multi-axis Linkage) is the control method. It is used to process concave and convex forms and manually change tools.

Drilling machine

A drilling machine is a machine that can do a variety of tasks, such as drilling, countersinking, threading and reaming. A radial drilling machine can be equipped with technological equipment. It can also bore when equipped with a bench drilling machine.

Processing and scope of conventional machine tools

The drilling machine is divided into single and double work tables, the control method is point position, straight line, drilling, reaming, tapping; two fixed worktables, one for machining, the other for loading and unloading parts, linear tool magazine.

Gear machine

A gear processing machine is a machine that can be used to process various spur gears, bevel and other parts. The control system is linear and the tooth shape changes in motion. It can be divided into three types of processing: gear hobbing, gear hobbing, and gear grinding machines.

Machine for milling:

This machine can cut spur, helical, worm, and sprocket gears. This machine uses a worm cutter for processing straight, helical and herringbone spur and/or worm gears, depending on the generation method. This machine can also process special workpieces such as sprockets, splines, and other gear workpieces with a special cutter

The normal gear hobbing machine's processing accuracy is 7-6 grades (JB179-883), while the high-precision hobbing machines are 4-3 grades and have a maximum machining diameter of 15m.

Gear shaping:

This machine uses a cutter to shape gear parts. It can process internal and outer spur, helical spur and helical-spur gears. The shaping cutter rotates in relation to the workpiece and makes up and down cutting motions during gear shaping.

The main purpose of the gear hobbing machine, apart from processing multiple gears and inner gears, is to also process racks with accessories. Special tools can be used on the gear shaping machines to process non-circular and incomplete gears. They also have internal and external forming surfaces like square holes, hexagonal holes and keyed shafts. Grade 75 (JB179-83) can be achieved in machining accuracy, while the maximum workpiece diameter can reach 12 meters.

Machine for grinding:

The grinding wheel can be used to machine spur gears and certain gears (helical or bevel). To machine the surface of the tool's gears.

There are many types and specifications of machine tools for cutting gears. These include small machines that can cut small parts, larger machines that can handle large diameters of over ten meters, high performance machines for mass production and high-precision machines for making precision gears.

Machines to process shea gearsRoko can be found in many industries, including automobiles, tractors and machine tools.
