There are three ways to connect the tool system with the tool, which are used in different machining environments.
There are three ways to connect the tool system with the tool:
This connection mode is mainly used for clamping cylindrical tools, which can be divided into two types:
(1) Three point clamping, as shown in Fig. 8-6a, drill the chuck handle.
(2) 360 ° clamping, as shown in Fig. 8-6b, spring collet tool handle, heat shrinkable tool handle.
Fig. 8-6 Connection mode of tool and tool system under clamping action
This connection mode is mainly used for clamping cylindrical and planar tools, and can be divided into the following two types according to the direction of pressing action:
(1) Radial compression, side fixed tool handle, as shown in Fig. 8-7a.
(2) The axial compression, face milling cutter shank and TMG21 tool system are shown in Fig.8-7b.
a) Radial compression
b) Axial compression

3. Self positioning of conical surface
This connection mode transmits torque by static friction between cones, as shown in Figure 8-8.

The NC tool system is generally composed of tool handle, extension bar and various tools.
The tool system used by the machining center is the boring and milling tool system.
The boring and milling NC tool system is the general name of the tool handle connecting the boring and milling spindle to the tool, as shown in Fig. 8-9.
It is mainly used to connect the spindle and the tool, so that the tool of the boring and milling machining center can reach the required position and precision, transmit the torque required for cutting and ensure the rapid replacement of the tool, as shown in Fig. 8-10.
