The tool loader is the assembly fixture of the tool, which is used to assemble and disassemble the tool handle.
Generally, the tool loader is divided into two types, one is a common tool loader (see Fig. 8-11a), and the other is a modular tool loader (see Fig. 8-11b).
Due to structural limitations, the common tool loader can only be used to fix several types of tool handles, while the modular tool loader can be matched with various types of tool handles by changing the bushing and flange plate, so that it can be applied to various types of tool handles.

a) Common tool loader b) Modular tool loader
The process of assembling the tool handle with the tool loader is briefly described as follows:
(1) Select the flange, collar and bushing suitable for the tool for assembly (see Fig. 8-12).
Fig. 8-12 Select the appropriate flange, collar and bushing
(2) Select the bushing suitable for the interface.
Fasten the fixture to the workbench with 3 socket head cap screws (see Fig. 8-13).

(3) Install the modules of the tool handle in order.
2. Specification of tool system
1. Specification of tool handle
Most of the tool shanks of boring and milling machine tools and machining centers use 7 ∶ 24 taper tool shanks, and the corresponding form of rivet tensioning mechanism is used to match the machine tool spindle.
The commonly used specifications are No. 30, No. 40, No. 45, and No. 50.
Among the new tool handles, HSK tool handles designed with a 1 ∶ 10 cone structure have six types: A, B, C, D, E and F.
The commonly used types are A type 63, 100, C type 63, 100, E type 40, 50, 80, F type 40, 50, 80. The common types of CAPTO tool handle are C3, C4, C5, C6, C8 and C10.
2. Specification and quantity of tool handle
The integrated TSG tool system includes 20 kinds of tool handles, with hundreds of specifications. Users can select the variety and specification of tool handles according to the NC processing technology of typical parts to meet the processing requirements without causing overstock.
Considering that a certain number of tool shanks are in preset or tool grinding while the CNC machine tool is working, the number of tool shanks is usually 2-3 times that of the required tool shanks.
