Application of CNC tool holder in CNC machining center!

November 22, 2021

Generally speaking, the NC tool holder is used to connect the mechanical spindle and tool in the CNC part machining center, which plays a bridge role. In fact, it plays a connecting role. The bearing is mainly reflected in: some performance, torque, speed and other parameters of the main shaft are output through the tool handle; The lower opening reflects that the tool handle should be clamped to realize normal machining. Therefore, Sheng Anbei believes that the role of NC tool holder in CNC machining center is particularly important.

1. The interface between the tool handle and the spindle realizes the cooperation, so the performance can be brought into full play during machining, such as precision, service life and so on. If the wedge fit between the spindle and the NC tool handle is not so good, the assembly accuracy may exceed the standard range. First, the spindle will react poorly and make a lot of noise during processing;

2. When the noise is high, the vibration value also increases accordingly. If it is reflected on the tool, the machining accuracy will become worse and the surface finish of the machined parts will be poor. Then it will certainly have an impact on the life of the spindle and tool. Thus, the production efficiency of the enterprise will be reduced and the cost will increase.

2、 Main classification and application fields of tool handle

According to the larger interfaces, there are two general types.

One is the 7:24 universal interface, including German standard, national standard and Japanese standard; The other is the widely used 1:10 interface. At present, 7:24 is more common, and 1:10 is the tool handle of HSK vacuum system. There are also some heat shrinkable and hydraulic, including the ultrasonic series currently being made, which are more divided according to the form of clamping.

The application of NC tool holder in CNC machining center is a key link that can affect the machining quality of parts. It must not be regarded as a general component. When the spindle rotates, the dynamic imbalance will cause periodic sensation. Therefore, the NC tool handle produced by shenganbei is mainly used for conventional machining and mold processing in the market, such as processing in electronics and mobile phone communication industries.
