The principle of auto tool change cnc router

The auto tool change cnc router is a high-end automatic knife changing engraving equipment, which is mainly based on computer control technology and mechanical transmission technology. The following is a detailed explanation of the principle of the auto tool change cnc router:

1、 Overview of Working Principle

The working principle of the straight row tool changing engraving machine is to control the driving motor and tool changing system through computer software, so that the tool can move accurately in the XYZ directions, thereby engraving the desired pattern or text on the material. At the same time, through the straight row automatic tool changing system, different types of tools can be quickly replaced to adapt to different materials and processing needs.

2、 Principles of Mechanical Transmission

Rack and worktable: The rack is the main structure of the engraving machine, and the worktable is used to fix the processing materials. The stability and accuracy of the rack and workbench are crucial for the quality of engraving.

Drive motor and lead screw: The drive motor drives the lead screw to rotate, and through the precise coordination of the lead screw and guide rail, the tool can move accurately in the XYZ directions. The precision of the screw and guide rail directly determines the machining accuracy of the engraving machine.

Guide rail and slider: The guide rail provides a precise path for the movement of the tool, while the slider ensures that the tool can move smoothly along the guide rail.

3、 Principles of Computer Control

Software control: The engraving machine receives and parses designed patterns or text through computer software, converting them into digital signals. Then, the computer sends these digital signals to the drive motor to control the movement trajectory of the tool.

Sensor feedback: During the carving process, sensors will monitor the position, speed, pressure, and other parameters of the tool in real time, and feed back this information to the computer. The computer adjusts the tool's motion trajectory and speed based on this information to ensure the accuracy and efficiency of engraving.

4、 Principle of automatic tool change

Straight line tool storage: The straight line tool changing engraving machine is equipped with a straight line automatic tool storage, which can store multiple cutting tools (usually customized according to processing needs). The tools in the tool magazine are arranged in a predetermined order for quick replacement.

Tool changing mechanism: When it is necessary to change the tool, the tool changing mechanism will automatically select and remove the target tool according to the instructions of the computer. At the same time, it will also return the currently used tool to the designated position in the tool magazine.

Laser or pressure sensor: During the tool changing process, the laser or pressure sensor will monitor the position and status of the tool in real time. These sensors can ensure accurate replacement and installation of cutting tools, thereby improving the accuracy and efficiency of engraving.

5、 Application scenarios and advantages

The auto tool change cnc router is widely used in the processing of solid wood door decoration threads, paint free doors, paint free cabinet doors, furniture, panel bathroom cabinets, speakers, game cabinets, computer desks, sewing machines, musical instruments, as well as various plastics, metal sheets and other fields. Its advantages include:

High precision: Using high-precision guide rails, screws, and sensors, it can achieve millimeter level machining accuracy.

High efficiency: With the ability to quickly change tools and perform high-speed cutting, it can complete a large number of carving tasks in a short period of time.

High degree of automation: reduces manual intervention and improves production efficiency.

In summary, the straight row tool changing engraving machine is a high-precision, high-efficiency, and automated mechanical processing equipment. Its principle is based on the combination of computer control technology and mechanical transmission technology. By accurately controlling the motion trajectory of the tool and quickly changing the tool, it achieves fine carving and processing of various materials.
