Carbide anti-vibration internal boring bars

Jul 01, 2019

The anti-vibration tool bar is an important tool accessory in CNC machining. The purpose is to prevent the vibration of the tool, to control the vibration of the tool, or to maximize the ability to prevent the tool from vibrating. In the cutting process, the vibration of the tool is inevitable, so there is no way to change this fact, you should choose to use a tool bar that can play a role in earthquake resistance.


The anti-vibration tool bar is also called CNC extension rod, especially the development of CNC precision machining. The traditional CNC machining is from 5000 rpm to 6000 8000 rpm. More precise and efficient cutting speed will be developed to more than 20,000 rpm. With such high-speed cutting, the rotational speed requires higher requirements for the use of the arbor, and must have sufficient seismic performance. To achieve the seismic performance required for such high-speed cutting operations, the cemented carbide anti-vibration shank must have uniform material and perfect consistency. Precision concentricity guarantee.

It is not easy to prevent the vibration of the tool. It will be easy to damage the tool. If the tool is broken, it needs to be reinstalled with a new tool, which not only delays the working hours, but also increases the industrial cost. Therefore, in industrial processing, the anti-vibration tool bar The choice is very important. Some people say that the cost of this tool holder is relatively high, but think about it from another angle. If you do not choose to use this special tool bar, the cost of the damaged tool will be even higher. In fact, it is a truth. And frequent tool changes will affect the process of factory processing, not only delay the work schedule, but also affect the speed of completion, which has a great impact on the production efficiency of the enterprise.


In the machining industry, the vibration of CNC tools is the biggest enemy and killer of machining, because this mechanical vibration is inevitable. In addition, this mechanical vibration will cause the precision of the workpiece to drop drastically after the mechanical workpiece is severely damaged. So how to control and solve this kind of mechanical vibration has become an important topic in the machining industry. Under such a background, CNC tools need a special anti-vibration hard alloy arbor. The hard alloy anti-vibration arbor makes full use of hard The material properties of the alloy, and in order to facilitate the user and save the user cost, the lock tooth design is used to liberate the operation space of the CNC cutter head. The cemented carbide anti-vibration tool bar is integrally formed by the solid carbide round bar. The integrity of the hard alloy material makes the alloy material with high hardness and small deformation. The stability of the machined workpiece greatly exceeds the stability of the ordinary steel tool bar, and the mechanical vibration value is minimized. The long-diameter ratio of the cemented carbide anti-vibration shank is such that the anti-vibration alloy arbor is more suitable for the difficult and high seismic requirements of the small-diameter deep-hole machining.

Most of the rods of the anti-vibration shank are hollow, which can minimize the vibration generated during processing. These anti-vibration shanks are suitable for high-precision machining in the machining center, and can also be used in high-speed engraving and high-speed milling. as follows:

1. Made of tungsten carbide, it has excellent rigidity, good shock absorption and no distortion due to excessive lateral force.

2. Extend the processing depth, improve the precision of the machined surface, and realize the possibility of ultra-long, ultra-deep, ultra-high precision machining.

3. There is no concern about welding fracture, emphasizing the variability of the cutter head. A cemented carbide arbor can reach dozens of combinations, which can cover all processing requirements of coarse addition to fine.

4. The cutter head and the cutter rod are threaded and run in opposite directions from the main shaft.

5. Even if the cutter head is damaged, the cutter bar can be reused! And the cutter head can be replaced quickly and easily on the machine.
