Three Easy Ways To Select Suitable Cnc Cutting Tools

We are an exporter of CNC cutting tools with 16 years’ experience. In the process of communicating with many customers, we found that helping them choose suitable products is part of our responsibility. Therefore, through this article, we hope to help more staff engaged in CNC machine processing to understand how to choose the right CNC cutting tools.

Why should we choose the right CNC tools

  • First, reformed CNC machine puts forward higher requirements for CNC machining tools, including higher precision, higher strength, better rigidity, higher durability, and necessary demands for stable size, easy installation, and adjustment. That is to say, the tool structure should be reasonable, and geometric parameters should be standardized and serialized.
  • Second, sutiable cutting tool is one of the prerequisites for improving processing efficiency. The right cutting tool not only helps us improve production efficiency but also reduces production costs.

How to choose the right CNC tools

  • The material of the processed workpiece

The cutting tool can be selected according to the material of the processed workpiece. For example, when turning or milling high-strength steel, titanium alloy, stainless steel parts, I recommend you to choose indexable carbide inserts with better wear resistance because they can extend the service life. While processing aluminum, copper and other soft material parts should choose end mills with a larger front angle but less than four flutes.

  • The processing stages

Choosing the right cutting tool based on the processing stages. The rough machining stage is mainly to remove the remains, so cutting tools should be with better rigidity, low precision. In the semi-finishing and finishing stage, we should choose high durability, high precision tools to ensure the quality product. The precision of the tool used in the rough machining stage is the lowest, and the precision of the tool used in the finishing machining stage is the highest. If we choose the same tool both in the rough and finish processing, then I will recommend choosing those tools used by the finishing machining, because they are mostly slight wear, which will not affect the rough machining.

  • The characteristics of the machining area

Selecting cutting tools according to the characteristics of the machining area. And there is another point we should remember that size of the CNC inserts should adapt to the surface workpiece being processed. An end milling cutter is often used to process the peripheral contour of the flat workpiece. When processing planes, we often choose tungsten carbide milling inserts. HSS end mill is a good choice in processing lug boss and groove parts. When machining blank surfaces or doing rough machining, cemented carbide corn milling cutter can be selected. For some vertical surface and bevel contour shape processing, ball nose end mill, ring milling cutter, conical milling cutter, and disc milling cutter are often used.

Finally, it is also worth noting that, because all cutting tools are already installed in the knife library before the CNC machine works, choosing the right size for CNC machines can also help improve working efficiency.

Although the durability and precision of cutting tools have a great relationship with their prices, in most cases, choosing a good cutting tool helps us reduce the whole processing cost.

To sum up, I believe this article can deepen our understanding of CNC machining technology and help us choose the right CNC cutting tools. The way stretches endless ahead, I shall search heaven and earth. Only by constant learning can we go further and further in our career journey.
