A tool magazine is used to store tools and has become a critical component of the automatic tool changer (ATC) in CNC machining centers. Tool magazines are typically categorized into chain-type and carousel-type (disc-type) designs, with the choice depending on the required tool storage capacity.

A standard tool magazine consists of 8 main components: Carousel/Tool Changer, Tool Fork, Tool Holder, Collet, Tool Magazine Motor, Router Bits, Gripper Arm/Tool Change Arm, Controller. Each component plays a vital role in the tool magazine system. 

1. Carousel/Tool Changer

The carousel or tool changer is the primary structure for storing cutting tools. Driven by a motor, it rotates to position tools accurately for the spindle. The storage capacity (number of tools) varies based on the disc magazine design and user requirements.

2. Tool Fork

Common tool fork models on the market include:  

HSK Series: HSK63F, HSK25E, HSK40E, HSK63 (black), HSK50, HSK32E  

BT Series: BT30, BT40 (white), BT50  

ISO Series: ISO30, ISO20, ISO10, ISO25  

CAT Series: CAT40, CAT50  

Also you can find: 

SUN BT40 (short/long models)  

Cincinnati BT40  

Sanjet tool forks  

3. Tool Holder

The tool holder is mounted in the disc magazine and secures router bits using a collet. It acts as the interface between the cutting tool and the spindle, ensuring stability during machining. Common types include:  

ISO Series: ISO30-ER32-42L, ISO20, ISO40 G1/2, ISO30 ER32, ISO30 ER40  

CAT Series: CAT50 ER16, ER40  

HSK Series: HSK63F ER32, HSK63F ER40, HSK25E ER16, HSK25E-ER11-043MS, HSK25E-ER16-43MS  

NBT Series: NBT40-ER32-70  

BT Series: BT40 G1/2, BT40 ER32 70L, BT30  

BBT Series: BBT30-ER16M-160H  

4. Collet 

Popular collet models include:  

ER16: ER16-3mm to ER16-10mm  

ER20: ER20-3mm to ER20-13mm  

ER25: ER25-1mm to ER25-16mm  

ER32: ER32-3mm to ER32-20mm (including 1/8”, 1/4”, 1/2”)  

ER40: ER40-3mm to ER40-26mm  

OZ25: OZ25-3mm to OZ25-25mm (including 1/8”, 1/4”, 3/8”, 1/2”, 3/4”)  

5. Router Bits

Common types include Tiger T007, T008, T011, PCD diamond router bits, and customized designs.  

6. Gripper Arm/Tool Change Arm

This arm retrieves tools from the magazine and positions them into the spindle or tool holder.  

7. Tool Magazine Motor

The motor controls the rotation, positioning, and storage of tools. Example models include:  

I-TA FM22 0.55KW AEV550 POJU DETA ATC tool magazines

MINCHUEN tool magazine motors

8. Controller

The controller manages the tool magazine’s automated operations, ensuring precise coordination between components.
