Let's find out how to use this special cobalt-chromium-molybdenum milling cutter so that we can get twice the result with half the effort and get the job done efficiently. A good solution for cobalt-chromium-molybdenum machining starts with a clear understanding of how to use cobalt-chromium-molybdenum milling cutters correctly.


As a senior engineer, we need to understand which type of tool is required in different situations, otherwise the best tools will be wasted. First of all, in mould CNC machining, milling parts inside and outside the contour and milling plane commonly used flat bottom end mills, for some three-dimensional surface and variable bevel contour profile processing, commonly used ball milling cutter, ring milling cutter, drum milling cutter, conical milling cutter and disc milling cutter.


1、Choose the tool for mould CNC milling


Mould milling tool is used for processing mould cavity forming surface, the cavity part of the processing is mainly rely on a variety of end mills. Mould milling cutters are evolved from end mills.


According to the shape of the working part, they can be divided into three types: conical flat head, cylindrical ball head and conical ball head.


According to the material, they are divided into carbide mould milling cutters, high-speed steel mould milling cutters, etc.


In addition to milling various mould cavities, they can also replace hand files and grinding wheels for cleaning the burrs of cast, forged and welded workpieces, as well as for finishing certain shaped surfaces. The following table shows the structure of the milling cutter for different processing methods.

Reasonable tool life is generally divided into the highest productivity tool life and the cost of tool life, the former according to the minimum work hours per piece to determine the goal, the latter according to the cost of the process to determine the goal.


Compared with ordinary machine tool processing methods, CNC machining of tools put forward higher requirements, not only the need for good rigidity, high precision, but also require dimensional stability, high tool life, while requiring easy installation and adjustment to meet the requirements of high efficiency of CNC machine tools. CNC machine tools are often used to adapt to high-speed cutting tool materials, and the use of indexable inserts. For the installation of tools, tool change and adjustment of more complex multi-tool machine tools, combined machine tools, tool life development standards should be selected higher, but also to ensure tool reliability. When the workshop productivity of a process limits the productivity of the entire workshop to improve, or a process unit of time to share to the plant-wide expenditure is larger, tool life should also be selected lower.


Tool life can be determined by taking into account factors such as tool manufacturing, sharpening costs and complexity. For short tool change times for machine indexable tools, tool life can be chosen to be lower in order to improve productivity and give full play to their cutting performance. The life of complex and high precision tools should be chosen higher than that of single-edge tools. When finishing large parts, in order to ensure that at least one tool is completed, to avoid changing tools in the middle of cutting, tool life should be determined by the accuracy of the part and surface roughness.
