In the field of machining industry, CNC machining center belongs to precision machining equipment, mainly because of the high precision of the machine tool itself, computer programming command CNC operation. CNC machining center machine tool spindle high precision, look at the requirements of high-speed machining tool understanding
In the process of machining mechanical parts, high-speed CNC machining is very important for the selection of cutting tools. The selection of cutting tools is mainly considered from two aspects,
The first is: the dynamic balance state of the cutting tool under the high-speed rotation state;
The second is: how to ensure the life of the tool. In order to ensure the tool can rotate stably around the axis at high speed;
At present, there are two approaches:
One is: the tool with dynamic balance device is used, which is equipped with mechanical slider or fluid dynamic balance design in the tool sleeve;
Second, the integral tool is adopted, and the tool sleeve and the tool body are integrated to ensure the minimum clearance between the tool body and the tool sleeve in the installation process. From the overall performance point of view, the overall tool in this aspect is the most ideal. However, as the tool sleeve and the tool body are integrated, once the tool body is scrapped, the tool sleeve will be scrapped together, so the cost is higher. In the process of parts processing, different materials have different requirements for tool selection. For example: aluminum processing is the first aluminum knife, there is a hardness of steel need to choose different hardness alloy coating knife. Under the operation of high-speed CNC machining, the overall requirements of CNC tools are balance, advanced materials, high manufacturing accuracy, safety, easy chip removal and multi-purpose.
The above is the understanding of the requirements of high-speed CNC machining tools,
