Tungsten steel is the raw material used in the tool industry today, and its remarkable superiority determines its application. However, in addition to distinguishing the true and false tungsten steel in the purchase of tungsten steel milling cutters, there are three main points to be aware of.
Pay attention to the end mill clamping clip /> At present, most of the methods used to process end mills are in the form of spring clips and set clips, which are used in cantilever conditions.
In the process of milling, there is a possibility that the end mill will slowly protrude from the inside of the holder, or even fall completely, resulting in the scrapping of the parts, which is usually due to the inside of the pocket and the end mill. There is an oil film between the outer diameters of the shank, resulting in insufficient clamping force.
Pay attention to the vibration of the end mill
Because there are very small gaps between the end mill and the tool holder, the tool is likely to vibrate during the process.
The vibration will cause the edge cutter of the end mill to have an uneven amount of the knife, and the amount of cut will be much larger than the originally set value, which will interfere with the accuracy of the machining and the service life of the tool.
Pay attention to the cutting of the end mill of the end mill
When the machining of the cavity and other CNC milling cutters is performed, when the position to be cut is the downward recessed portion or the deep cavity, the amount of extension of the end mill must be increased.
If a long-blade end mill is used, the deflection of the inner cutter is relatively large, which is prone to vibration and damage to the cutter.
Therefore, if the processing flow is summarized, if only the cutting edge around the end of the tool is required for cutting, it is better to use a short-blade long-shank end mill with a long total tool length.
Tungsten steel milling cutters seem to have a lot of places to pay attention to, such as the choice of cutting parameters, the choice of cutting methods, the use of carbide end mills, etc., in order to be able to choose the right milling cutter to ensure the tool Safe to use.
