The cutter head of the milling machine is divided into asphalt cutter head and cement cutter head. Its working mode is to use the top tungsten carbide alloy to keep rotating and cutting on the road surface. It is used on the milling drum of the milling machine.

At present, the most commonly used tool heads in the market are German Wittgen and Xugong. The tool head materials on the market are basically the same, all using 42CrMo, but the manufacturing process is not consistent, which leads to the uneven quality of the tool head in the market. So how to choose the high quality milling machine tool head

Users can consider the following points:

The materials used in the head and body of the tool; 2. Whether the welding is firm; 3. The hardness of the tool head heat treatment should not be too high; 4. Expanding tension of gasket clamp spring.

To understand the choice of milling machine tool head, it can recommend some reliable manufacturers, here, I recommend for your conscience, first of all, you can see the manufacturer of part of the head picture

The production process of the cutting tools is: the blank forging - CNC machining - vacuum welding, vacuum quenching - tempering - surface treatment - installation - table, the advantage of the production process or different from other factory production process is: vacuum welding and vacuum quenching, the two process enables bit more wear resistant and not easily broken, milling cubic number more, greatly improve production efficiency.

The advantage of vacuum welding is the use of copper and manganese welding, the temperature can reach 1000°-1100°, so that the alloy will not be lost, the tool head is not easy to break, while other manufacturers mostly use high-frequency welding, the temperature can only reach 800°, the alloy lost in the welding process, resulting in the tool head is not wear-resistant and easy to break.

Other manufacturers adopt high frequency quenching, which only makes the HRC of 2.5mm on the surface of the tool head reach 55 degrees, which leads to the surface hardness is enough, but the inner part is empty, resulting in the tool head is easy to break. However, the vacuum quenching adopted by this manufacturer makes the HRC of the tool head reach 52 degrees, and the HRC of the tool head bar reach 38 degrees in the annealing process, thus improving the wear resistance. For example, the tool head of this manufacturer W6 can be milling 1200 square.
