Different types of auto tools changer of ATC CNC Router

The Advantage of an ATC System

Like the manual woodworking machine, you can change tool bits all the time for different sections of work. To achieve a better finishing result and much faster turnaround times, you will need Spiral Bits with different numbers of Flutes. In other words, you will need a plunge cut, a dado cut, an up cut and down cut, and the list will go on and on. And not even to mention grooving where you can have so many different shaped groove bits to get a single job done in one pass.

Without the ATC (Automatic Tool Change) function, you will have to use a small finishing/engraving bit to perform the job from the beginning and it will take ages to get the job done. Plus you will have to use a large carving, relieving or roughing bit and get a rough finish. This frequent tool bit change and repositioning of the CNC Router spindle will result in the manual tool change becoming impracticable.

Different types of Auto Tools Changer

We divide the tools changer to two types,which are Linear tools changer(tools arranged in a line) and Circle tools changer(tools arranged in a circle). 

 The linear automatic tools changer can be arranged at two positions
The tool changer at the far end of the cnc router table, this design does not affect the feeding height. When change the tool,the spindle moves to the far end of the table. Auto loading and unloading panel furniture production line can not use this type tool changer. 

The tool changer attaches to the gantry, it has fastest tools changing speed due to nearer distance from the spindle. The tool changer affects the feeding height,this design is suitable for thin materials like MDF,chipboard,plywood for panel furniture.

The circle automatic tools changer can be arranged at two positions as well

 Mount at side of table. It does not affect Z-axis feeding height and not far from spindle. 

 Close by the spindle. When auto changing the tool, a cylinder will push the magazine closer to the spindle,save the time of moving to end of table. This type tools changer is suitable for thin materials only. 

The circle tools magazine is driven by a servo motor,thus it result in higher price of this types ATC. Linear type ATC became more popular than circle type due to its high cost-effective.
