What is a CNC Tool Magazine?

A CNC tool magazine is a storage device integrated into CNC machining centers, designed to automatically change tools during machining processes. By enabling automated tool switching, it reduces production costs, shortens processing times, and enhances efficiency in operations such as milling, drilling, boring, and tapping. This article clarifies the types and features of tool magazines.

Types of Tool Magazines

Tool magazines are devided into two types based on their structure: Chain Tool Magazinesand Carousel-Type Tool Magazines.

1. Chain Tool Magazine

Chain tool magazines are capable of storing a large number of tools, typically exceeding 20 and sometimes up to 120 or more. They feature a simple, fast, and reliable structure. Due to their high customization potential, chain-type magazines are generally more expensive. Tools are transferred via a chain mechanism to the desired position, where a robotic arm installs them onto the spindle.

2. Carousel-Type Tool Magazine (Disc-Type Tool Magazine)

Commonly used in machining centers, carousel-type tool magazines automate tool changes to improve efficiency and minimize downtime. The magazine rotates to position the required tool, which is then swapped into the spindle. Key features include:

Compact Design: Ideal for smaller CNC machines due to their space-efficient footprint. Capacity ranges from 2 to 30 tools. 

Fast and Precise Tool Selection: Circular rotation ensures quick and accurate tool positioning.

Low Maintenance: Simple mechanical structure reduces the risk of failure and ensures reliability.

Also you can find  Drum-Type Tool Magazine and Arm-Type Tool Magazine Based on Mounting Design

1. Drum-Type Tool Magazine

The most common design, drum-type tool magazines arrange tool pockets around a rotating drum. This design reduces dust and chip contamination by up to 80%, protecting tool tapers. The drum rotates to align the desired tool with the spindle. A variation of this design is the bucket magazine, which uses a similar rotational mechanism.

2. Arm-Type Tool Magazine

Controlled by a servo system, arm-type magazines use linear arms to transfer tools between the magazine and spindle. They offer greater flexibility for handling diverse tool shapes and longer travel distances. However, their complex design increases mechanical intricacy and maintenance requirements.

Tool magazines have become indispensable components in modern CNC machining centers, enabling advanced automation and operational efficiency.
