Milling machine cutter head generally consists of (tungsten), the tool body, retainer, card four components, a few of the teeth (tungsten), the tool body, retainer three components, whether imported or domestically and milling machine models, although there are many, but the head of the specification, but only two, one shank diameter is 20 mm and the other shank diameter is 22 mm, while the appearance or shape is vary, there are conical, have undercut the band, but also with the spin-up slot, but always maintain the conical shape, the purpose is to be able to more quickly cut ground material, ensure cutter, cutter body uniform wear!
Cutter is used to cut direct contact with the ground and the ground material, which not only have good wear resistance, but also has high impact resistance! Tungsten-cobalt alloy commonly used vacuum sintering, soldered directly on the tool body, its bending strength is 2400n / mm2, between density 14.5-14.9cm3, high density, strong wear resistance!
Alloy tool body is to protect the teeth, the choice 42Crmo resistant materials, the use of cold extrusion and then machined from high bending strength, wear resistance and strong!
Hardness is an important guarantee to ensure the normal use of the head, a reasonable quenching hardness or play head to prolong the service life of the tool body between hardness 44-48HRC, tooth hardness between 88-89HRA;
Bank of high frequency welding technology, welding firm, ensuring alloy tooth head never fall off;
Card by pressing high elasticity 65Mo then quenched steels made it not only can easily replace the blade, and can effectively protect the knife, so the knife to minimize unnecessary wear!
Retainer is made of high elastic 65Mo steel pressing, the expansion force! Long-term head firmly locked and make sure the tip of the knife can be flexible in the rotation;
