How To Improve The Service Life Of Tungsten Steel Milling Cutter?

DALIAN, China - Jan. 10, 2022 - PRLog -- Tungsten steel milling cutter is a tool made of tungsten steel (hard alloy, also known as tungsten titanium alloy). Generally, it is mainly used for CNC machining centers and CNC engraving machines. It can also be installed on an ordinary milling machine to process some harder and less complex heat-treated materials. Tungsten steel milling cutters are widely used and high-speed processing is used. The hardness of the tungsten steel milling cutter is Vickers 10K, second only to diamond. Because of this, the tungsten steel milling cutter has the characteristics of not being easily worn, and it is brittle and hard not afraid of annealing.

Tungsten steel milling cutters are particularly important for the high temperature resistance and heat resistance of the coating. Due to the high hardness of the coating, high oxidation temperature resistance, and superior tool wear resistance. At the same time, the current tool holder adopts a thermal expansion tool holder with a very high clamping force. Nowadays, thermal expansion tool holders have high runout accuracy and are used in many finishing centers. The strong clamping force and low vibration can also be used for rough machining, so tungsten steel milling cutters that are prone to chipping can also achieve stable machining.
If the tungsten steel milling cutter is abnormally worn or chipped and causes a sharp wear, then it is necessary to select the tool and modify the cutting parameters. In order to increase the strength of the tool, it is also effective to use a negative rake angle shape, and at the same time choose a fine ultrafine cemented carbide material with high hardness. The correction of the cutting conditions is not to reduce the feed rate by a large margin, but to reduce the cutting amount first. In order to maintain the wear resistance of tungsten steel milling and achieve a good machining surface, it is more important to choose high cutting speed than low cutting speed. The cutting amount is reduced in order to achieve stable machining in the case of high-speed milling.
