How to Choose Carbide Cutter Under Machining Conditions

Now, the carbide cutter, which is not easy to wear, is very popular in the market because it can effectively process different materials. But with the development of technology, there are different types of carbide cutters on the market now. As a consumer, facing so many carbide cutters, how to choose carbide cutter under machining conditions? Don't worry, this article will provide you with useful suggestions for choosing a carbide cutter. We will introduce you how to choose a carbide cutter from three aspects. I believe this article will definitely help you.

• Choose a carbide cutter according to the width and depth of milling

• Choose a carbide cutter according to the rigidity of the machine tool

• Select the carbide cutter according to the high-speed tool path

1. Choose a carbide cutter according to the width and depth of milling

We can choose the size of the carbide cutter you need according to the milling width and depth. This is a common sense, the greater the depth and width before milling, the larger the diameter of the carbide cutter. But when we need precise milling, we should choose a larger diameter carbide cutter, this is to reduce the mark of the tool between two adjacent feeds. But if it is rough milling or face milling of large parts, you can choose a carbide milling cutter with a smaller diameter. This leaves a lot of room for improving productivity. Under ideal working conditions, the carbide cutter should have 70% cutting edge participation. You have to choose the carbide cutter according to the hole diameter. If the diameter of the selected carbide cutter is too small, a core may be formed in the center of the hole. Falling of the material core will damage the workpiece and tool. However, a carbide milling cutter with an excessively large diameter cannot cut the material in the center, so the bottom of the tool will collide, which will cause damage to the tool and the workpiece.

2. Choose a carbide cutter according to the rigidity of the machine tool

We can choose the carbide cutter according to the rigidity of the machine tool. Different machine rigidity needs to choose different size carbide cutter. You have to consider the capabilities of your machine tool to choose the right carbide milling cutter. You can check the stiffness of your machine tool and find relevant information. Here is an example. When you need to cut on a 40-taper machine, you should choose a carbide cutter with a diameter less than 12.7mm. Although we all know that a carbide milling cutter with a larger diameter will produce a greater cutting force. However, if the selected carbide milling cutter is not suitable for your machine tool, poor surface finish will occur during the machining process, and it will also cause damage to the carbide cutter.

3. Select the carbide cutter according to the high-speed tool path

The combination of high-speed cycloid tool path and CAD/CAM system greatly improves cutting accuracy. And when the carbide cutter cuts into corners or other complex geometric shapes, the amount of tooling will not increase. Compared with a carbide milling cutter with a larger diameter, a small-diameter carbide cutter can often remove more workpiece material per unit time if it is under the condition of a high-speed tool path. Because the contact surface of the large-diameter carbide milling cutter and the workpiece is larger, it is necessary to reduce the feed speed. Small diameter carbide cutter can achieve higher metal removal rate under the condition of high-speed tool path. Moreover, the price of small-diameter carbide cutter is lower than that of large-diameter carbide milling cutter, it will be a cost-effective choice.
