What are the components of CNC machine tools?

Generally, it is composed of control system, numerical control system and servo system.

and the machine tool body. CNC machine tools are generally composed of the following parts:

The main machine, which is the subject of CNC machine tools, includes mechanical components such as machine body, column, spindle, feed mechanism, etc. He is a mechanical component used to complete various cutting operations.

The numerical control device is the core of the CNC machine tool, including the hardware (printed circuit board.

CRT display, key box, paper tape reader, etc.) and the corresponding software, which are used to input the digital part program, and complete the storage of input information, the transformation of data, the interpolation operation and the realization of various control functions.

The drive device is the driving component of the actuator of the CNC machine tool, including the spindle drive unit, the feed unit, the spindle motor and the feed motor. He implements the spindle and feed drive by means of an electrical or electro-hydraulic servo system under the control of a numerical control unit. When several feeds are linked, positioning, straight lines, plane curves and spatial curves can be processed.

Auxiliary devices, some necessary supporting parts of the index control machine tool, are used to ensure the operation of the CNC machine tool, such as cooling, chip removal, lubrication, lighting, monitoring, etc. It includes hydraulic and pneumatic devices, chip removal devices, exchange tables, CNC turntables and CNC indexing heads, as well as tools and monitoring and testing devices.

Generally, CNC machine tools are divided into 16 categories:

1. CNC lathes (turning centers with milling functions).

2. CNC milling machine (including milling center).

3. CNC cenging machine.

4. Machining center mainly for milling

5. CNC grinding machine (including grinding center).

6. CNC drilling machine (including drilling center).

7. CNC broaching machine.

8 CNC planers.

9. CNC cutting machine tools.

10. CNC gear processing machine tools.

11. CNC laser processing machine tools.

12 CNC EDM wire cutting machine tools.

13. CNC EDM machine tools (including electric machining centers).

14. CNC plate village forming processing machine tools.

15. CNC pipe forming processing machine tools.

16 other CNC machine tools.

The commonly used CNC machining machine tools in mold manufacturing are: CNC milling machine, CNC EDM machine tool, CNC EDM wire cutting machine tool, CNC grinding machine and CNC lathe.

CNC machine tools are usually composed of control systems, servo systems, detection systems, mechanical transmission systems and other auxiliary systems.

The control system is used for the operation, management and control of CNC machine tools, and the data is obtained through the input medium, and the data are interpreted and calculated and have an effect on the machine tool; The servo system drives the machine tool according to the instructions of the control system, so that the cutter and parts perform the movement specified by the numerical control; The detection system is used to detect the displacement and speed change of the machine tool execution parts (worktable, turntable, slide plate, etc.), and feedback the detection results to the input terminal, compare with the input instructions, and adjust the machine tool movement according to its difference; The machine tool transmission system is a mechanical feed transmission device between the feed servo drive element and the machine tool actuator; There is a wide variety of assistance systems. Many.

There are mechanical parts of CNC machine tools, such as beds, workbenches, columns, protective covers, etc.; Electrical parts such as CNC system, electrical control, PLC, etc.

CNC machine tools are mainly composed of the following systems:

1. Servo control system;

2. a mechanical mechanism system;

3. a lubrication system;

4. Computer-aided systems;

1. Host. Including machine tool body, column, spindle, feed mechanism and other mechanical components. Function: Mechanical parts used to complete various cutting processes.

2. Numerical control device.

This includes the hardware as well as the corresponding software. Function: It is used to input the digitized part program, and complete the storage of input information, the transformation of data, the interpolation operation and the realization of various control functions.

3. a driving device.

Including spindle drive unit, feed unit, spindle motor and feed motor, etc. Function: He realizes the spindle and feed drive by means of an electrical or electro-hydraulic servo system under the control of a numerical control device.

When several feeds are linked, it can be processed into positioning, straight lines, plane curves and space curves. Suchang.

4. Auxiliary devices.

Some necessary supporting parts of the index-controlled machine tool. Function: It is used to ensure the operation of CNC machine tools, such as cooling, chip removal, lubrication, lighting, monitoring, etc.

It includes hydraulic and pneumatic devices, chip removal devices, exchange tables, CNC turntables and CNC indexing heads, as well as tools and monitoring and testing devices.

5. Programming and other ancillary equipment.

Function: It can be used to program and store parts outside the machine. <>

CNC machine tools are composed of machine tool base castings (bed), tool magazine, XYZ three axes, tool magazine, CNC system, machine tool sheet metal and other machine tool accessories.
