What is ATC Cambox and how it works？
ATCs are generally used to improve the capacity of a machine to work with several tools at one time, but they can also be used to change out worn or broken tools. There are generally two types of automatic tool changers – rotary-style and linear-style – which vary in the number of tools present within the changer.
An automatic tool changer typically consists of:
- Base
- Gripper arm
- Tool holder
- Support arm
- Tool magazines (where the tools are stored)
How does an automatic tool changer work?
Once set up on your CNC machine, an automatic tool changer follows a quick set of steps to swap tools in and out. Here’s how it works.
The tool change command is given to the machine via the computer.
The tool to be changed assumes a fixed position known as the “tool change position.”
The ATC gripper moves to that position to pick up the tool.
Internally, the spindle opens or closes the chuck to exchange tooling before returning back to work.
In a matter of seconds, an ATC enables you to switch tools automatically without any need for human involvement (apart from programming the change).
What are the benefits of an automatic tool changer?
An automatic CNC tool changer has numerous significant benefits in the shop, including:
- Ability to switch between a large number of tools without requiring a human operator
- Increased accuracy
- Increased efficiency
- Reduced labor cost
- Reduced downtime and total production time
- Increased tool storage capacity
- Increased machine versatility
- Increased safety for employees and equipment
- Ability to change larger and heavier tools with ease
- Increased edge finish due to more appropriate tooling per process
- Increase your efficiency and production quality

The two primary types of ATC camboxes:
Vertical ATC Cambox VS Horizontal ATC Cambox
Here are some of the differences between the two:
1. Orientation: A vertical ATC cambox is mounted vertically above the spindle of the CNC machine.
2. Tool Change Speed: Vertical ATC camboxes typically have faster tool change speeds as they use gravity to aid in tool changes, allowing the tool to drop down quickly into the spindle.
3. Compactness: Vertical ATC camboxes take up less horizontal space, making them a popular choice for machines with a smaller footprint.
4. Stiffness: Vertical ATC camboxes are stiffer and provide more stability, resulting in higher accuracy and better finish quality.
1. Orientation: A horizontal ATC cambox is mounted horizontally beside or under the spindle of the CNC machine.
2. Tool Capacity: Horizontal ATC camboxes have larger tool capacity and can hold more tools than a vertical ATC cambox.
3. Maintenance: Maintenance of a horizontal ATC cambox can be easier than a vertical ATC cambox as it is located at the side of the machine and does not require overhead access.
4. Accessibility: The horizontal orientation of the ATC cambox can make it more accessible for tool change and maintenance, making it a preferred choice for certain types of machining applications.

- Last but not least, also consider the taper when choosing it!
Tapers are conical surfaces used to connect the tool holder to the spindle of a machine, ensuring accurate alignment and secure clamping of the tool. The taper angle represents the slope of the conical surface. The most common taper standards used in machining are the Morse Taper (MT), R8, and the more precise and rigid ones known as the ANSI/ASME B5.50 or ISO tool holder tapers.
The numbers associated with these taper designations, such as 20, 30, or 40, indicate the taper angle in degrees. For example, a 20 taper has a taper angle of 20 degrees, a 30 taper has a taper angle of 30 degrees, and a 40 taper has a taper angle of 40 degrees.
The choice of taper depends on the specific machining application, the machine tool being used, and the requirements of the cutting tools. Generally, higher taper angles provide increased rigidity and tool stability but may sacrifice some accessibility in tight spaces. Lower taper angles may offer better accessibility but could have limitations in terms of rigidity and cutting performance.
Choosing the perfect ATC cambox is a pivotal decision that directly impacts your machining operations' efficiency and performance.
