Basic requirements for tool use in NC machining of vertical machining center

The vertical machining center completes the machining by executing the machining program of the workpiece . And usually, if it is not urgent , Do not interrupt the execution of the vertical machining center program at will . Therefore, the vertical machining center requires sufficient rigidity and high strength for the tools used , Furthermore, in order to maintain the consistency of workpiece machining dimensions , The machining tool of the vertical machining center must have machining durability , Thus, this paper introduces the basic requirements for the use of cutting tools in the NC machining of vertical machining centers .

1、 The tool used should have high durability

The good durability of the vertical machining center tool is the key to ensure the machining accuracy of the workpiece , Especially when a milling cutter has a lot of processing content , For example, the tool is durable and wears slowly , It will not only improve the surface quality and machining accuracy of the workpiece , And it will reduce the times of tool adjustment and tool setting caused by tool change , Thus, the machining efficiency of the small vertical machining center is improved , And the tool receiving steps formed by tool setting error will not be left on the working surface , Thus, the surface quality and fitting accuracy of the workpiece are improved .

2、 The rigidity of the selected tool is better

The rigidity and durability of vertical machining center tools complement each other , Good rigidity the need to use large cutting parameters to improve production efficiency and the difficulty of adjusting cutting parameters in the process of NC machining . Further, when the machining allowance of the workpiece varies greatly , Traditional machine tools can be adjusted manually , It is easy to adopt layered milling method to solve , The NC milling of small vertical machining center must follow the tool path specified in the program , When the margin is large, it can not be like the general milling machine “ Random strain ”, The sudden excessive cutting force is a big test for the rigidity of the cutting tool , From this we can see the importance of tool rigidity .

To sum up, it is an introduction to the basic requirements for the use of cutting tools in the NC machining of vertical machining centers , And the reputable vertical machining center is a kind of CNC milling equipment equipped with tool magazine and automatic tool change device . Different from ordinary CNC milling machine , This kind of processing equipment has a high degree of automatic processing capability , And strong compound processing ability .
