How to use CNC tool holder to be worth the money?

Jinjie Machinery Bright-tools answer for you

The CNC tool holder is responsible for connecting the mechanical spindle and the tool in machining, which plays a role of connecting the upper and lower. The main manifestation is that some parameters of the spindle, such as performance, torque, speed, etc., are output through the tool holder; and the current embodiment is that the tool holder needs to clamp the tool to achieve normal processing, so the role of the tool holder is very important. Today Bright-tools brings you some relevant knowledge of CNC tool holders, hoping to provide convenience for everyone to use.

The first is adaptability. The interface between the tool holder and the spindle can be perfectly matched, so that the performance can be fully exerted during processing, such as accuracy, life and other aspects. If the spindle and the tool holder are not well matched, the assembly accuracy may exceed the standard range, and during processing, the spindle will respond poorly and the noise will be relatively large. When the noise is large, the vibration value will also be large. If it is reflected on the tool, the machining accuracy will be deteriorated, and the surface finish will be poor. At the same time, it will affect the life of the spindle and the tool, and thus the production efficiency of the enterprise. will decrease and costs will increase.

Since there are many types of tool holders, how to choose a tool holder first depends on the classification and positioning of the company's products. What kind of processing is done depends on what kind of machine tool is purchased, and the tool holder follows the interface between the machine tool and the spindle. After the machine tool and the spindle are selected, the general category of the tool holder is also determined. If it is roughing and conventional machining, the general BT type interface is usually used; if it is finishing, the ISO tool holders of small tool holders may be used. The weight is relatively light, it can run at high speed, and there is also the HSK tool holders, which is suitable for a more comprehensive tool holder.

For example, if the machine tool is of the BT30 tool holders, then it is the tool holder of the BT30 tool holders that is equipped with the machine tool. Under the BT30 series, there will be many interfaces, and the tools clamped by different interfaces are also different. If it is to be precision machined, it is recommended to choose the collet of the HSK tool holders.

There is also a shrink fit chuck  tool holder in the finishing process, and the principle of thermal expansion and cold contraction is used to achieve zero-error clamping. The type of tool holder can be determined according to the processing conditions of different enterprises. Another example is the ultrasonic series in some special fields, if the conventional processing methods cannot reach, some new tool holders will also be used.
