Collet Chuck Tool Holder

Collet Chuck Tool Holder

The structure of tool holder of NC machine tool can be divided into two types: integral mode and modular mode. The working part of the clamping tool of the integral tool holder is integrated with the handle used for fixing and positioning on the machine tool. This kind of tool holder has poor adaptability to the transformation of machine tools and parts. In order to adapt to the transformation of parts and machine tools, users must store various specifications of tool holders, so the utilization rate of tool holders is low. Modular cutting tool system is an advanced cutting tool system. Each tool handle can be assembled by a variety of serialized modules. For different parts and machine tools, different assembly schemes can be adopted to obtain a variety of tool shank series, thus improving the adaptability and utilization of tool shank.

Tool holder specification

Most CNC tool shanks adopt 7:24 tapered tool shanks, and the corresponding type of pull nail tension structure matches the machine tool spindle. Tool handle has various specifications, commonly used are No. 40, No. 45 and No. 50. At present, ISO7388-1983 and GB10944-are widely used in China.

Knife handle chuck series

In 1989, MAS403-1982, ANSI/ASME B5.50-1985 and so on, the specifications of the tool shank should be taken into account when choosing the machine tool spindle and manipulator.


Tool and handle matching

Pay attention to the matching of tool holder and tool, especially when choosing tapping tool holder, pay attention to the matching taper drive square head size. In addition, choosing single-edge boring cutter on NC machine tool can avoid scratching workpiece during tool withdrawal, but attention should be paid to the position direction of tool tip relative to keyway on tool handle: some machine tools require the same orientation as keyway, while some machine tools require that the orientation of keyway be perpendicular to the orientation of keyway.


Selection of High Efficiency and Composite Tool Handle

In order to improve the processing efficiency, high efficiency cutters and tool holders should be selected as far as possible. For example, the double-edged boring tool holder can be used for rough boring, which can not only improve the processing efficiency, but also help to reduce cutting vibration. The strong spring chuck can not only clamp the straight shank tool, but also clamp the tool with holes through the connecting rod. For typical workpieces with large batches and complex processing, composite cutting tools should be selected as far as possible. Although the price of composite cutting tools and tool holders is relatively expensive, the use of composite cutting tools in machining centers can combine multiple processes into one process and be completed by a single tool, which is conducive to reducing the processing time and the number of tool changes, and significantly improving production efficiency. For some special parts, special design of composite tool holder can also be considered.
