Definition

Tool interfaces form the mechanical link between the machine tool and the exchangeable tool.

Theory and Application

Introduction

As a direct link between the machine tool and the tool, the tool interface directly affects the performance and quality of the machining process.

The demand for drilling, turning, and milling tools that may be used universally on different machines has led to standardized interfaces being formed from the various manufacturer-specific systems. Due to the increasing degree of automation, current interface systems are now largely equipped for automatic tool change.

Types

For manual tool change only the Morse taper according to ISO 296 is used (Fig. 1) on shop floors in some cases. The force and torque transfer is achieved via the frictional contact of a self-locking taper angle of 1:20. For higher loads there are models with a clamp thread...
