The common form of ATC CNC router

Advanced tool machine tool changer is not only an important driving force for manufacturing technology and development but also an important means to improve product quality and reduce processing costs. Tool and machine tools are mutually restrictive and mutually promoted. ATC CNC router promotes The advancement of modern processing technology is manufacturing technology, which has entered a new era of ATC CNC router. There are several common forms of ATC CNC router

• Rotary tool post for tool change

• Replace the spindle head and change the tool

• Automatic tool change system with tool magazine

Tool change with a rotary tool post

The rotary tool post used on the CNC router is the simplest automatic tool change system. According to different processing objects, it can be designed into a square tool post and a hexagonal tool post. The command of the device to change the tool.

The rotary tool post must have good strength and rigidity in structure to withstand the cutting resistance during rough machining. Since the cutting accuracy largely depends on the tooltip device, for the CNC engraving machine, the tooltip position does not need to be adjusted manually during the machining process.

Therefore, it is more necessary to choose a reliable positioning scheme and a reasonable positioning structure to ensure that the rotary tool post has the highest possible repeat positioning accuracy after each indexing.

The entire movement of the rotary tool post is controlled by the hydraulic system through electromagnetic reversing valves and sequence valves. It is divided into four processes: tool post lifting, tool post indexing, tool post pressing, and indexing cylinder reset.

Replace the spindle head and change the tool

In the CNC engraving machine with rotation, replacing the spindle head is a relatively simple way to change the tool. There are usually two types of spindle heads, horizontal and vertical, and the indexing tower is often used to replace the spindle head to realize automatic tool change.

On each spindle head of the turret, the rotation required by each process is first installed. When a tool change command is issued, each spindle head turns to the processing position in turn, and the main motion is switched so that the corresponding spindle drives the rotation, and The other spindles in the non-processing position are disengaged from the main movement.

Automatic tool change system with tool magazine

The automatic tool change system with tool magazine consists of a tool magazine and an exchange mechanism. At present, it is the most widely used tool change method on the multi-process CNC router, and the entire tool change process is more complicated.

First of all, install all the tools that need to be used in the processing process on the standard tool holders. After adjusting the size outside the machine, put them into the tool magazine in a certain way. Take it out from the tool magazine and spindle;

After the exchange, load the new one into the spindle and put the old one back into the tool magazine. This method can be processed in a variety of complex procedures, especially in CNC drilling machines, CNC milling machines, and CNC boring machines.
