We will cover all there is to know about CNC lathes in machining systems in this post. The information includes the structure of the lathe and the operating principle of the CNC machine. I hope this knowledge will be of value to many of you who are learning about this device.

1. What is a CNC lathe?

nguyên lý hoạt động của máy CNC

A CNC lathe is a part of a mechanical processing machine system. A mechanical lathe system that is controlled and programmed by a computer to aid in proper workpiece processing is called a CNC lathe.

Wood cnc lathes and metal cnc lathes are the two most common forms of cnc lathes.

CNC lathes are similar in construction to traditional lathes, and are mainly used for making spinning parts.

2. Structure of CNC lathe

To understand the working principle of a CNC machine, you must first understand the structure of the machine. It takes a long time to fully absorb, so you have to break it down to absorb it.

The first step is to understand the overall structure of the CNC machine, what key elements it consists of and how they are related.

The CNC machine will include the main components such as:

-Control unit

-The motors for each shaft

-Machine table

-Knife, knife head

-Cooling system

-Hydraulic system if it is an old machine.

The basic structure of a CNC machine is as below, here is a 3-axis CNC milling machien.

And the detailed structure of the CNC machine will be relatively many. Consists of components such as:

Machine frame, protective shielding system

– System table, chuck, mounting bracket.

– Knife tray system, automatic tool change

– Knife head, all kinds of knives

– Air or water cooling system, gas clamp.

– Control system, connect with computer.

3. Operation mechanism of CNC lathe

The working concept of the lathe is based on the general material processing principle: The circular motion of the workpiece is the main movement, and the horizontal and vertical movement of the belt is the feed movement.

Therefore, the operating mechanism of the cnc lathe is the principle of adjusting the rotation of the workpiece as well as the principle of controlling the tool motion.

The workpiece is mounted on the chuck on the lathe (there are 3-pin self-centering types, there are 4-pin types). Center supports (there are two types of center heads: static center and dynamic center) located on the dynamic mound are often used to support workpieces of large length (about 200 or more) to increase rigidity.

The rotation of the main shaft (of the workpiece) is the movement of the chuck according to the following diagram:

Motor —> Gearbox —> Chuck

The engine of a lathe (mechanical lathe) is usually located behind the machine, under the machine base. Depending on the type of machine, this motor has different capacity and speed.

A belt drive transmits the rotation of the motor to the reducer. There are gear elements in the reducer that can be coupled in pairs to transmit motion to the chuck at different speeds. The speed levers on the speed box are used to select the desired speed.

– The movement of the tool is the movement of the tool table according to the following diagram:

Motor —> Gearbox —-> Transmission shaft——-> Knife table.

The movement follows the same motion and speed principles as the spindle.

The gears that divide the motion and the stages in the speed box allow the motor to provide motion to the table in addition to rotation for the main shaft.

The conveying machine uses longitudinal and transverse shaft drives because it is far from the speed box and must move freely in both longitudinal and transverse directions by the machine.

The gears in the level box are used to adjust the gearing of the wagon. On the body of the level box, there is a movement speed selection board
