Sandvik is a world famous special steel production enterprises, but also well-known metal cutting tools and drilling equipment and drilling equipment manufacturing enterprises. The company's production of milling teeth in Europe and North America occupies a considerable market share, is now on the road cut the product structure is described below.
As mentioned above, carbide ingot is a milling part that directly grinds concrete or asphalt pavement, even soft rock or medium hard rock, and requires good toughness and abrasion resistance in high temperature and high impact conditions The It is usually necessary to select tungsten carbide cemented carbide with different grain sizes according to the milling object (Fig. 6). The top of the cutting alloy is tapered to ensure that the milling resistance is reduced when cut into the ground; the bottom is large in diameter to provide protection against the reticulated steel body. The cutting alloy is welded to the cutter body by means of copper brazing, requiring high weld strength and shear strength to ensure that it can withstand the work of the road cold milling machine applied to the alloy teeth and cut the highest 45 ° direction Up to 6 tons of force and the corresponding bending moment. Sandvik company milling cutter alloy main shape and characteristics in Table 3.Road Repair Equipment - Doan Machinery
Milling machine with cutting, in the road cold milling machine on the road maintenance construction process, milling materials, milling depth, milling power, working speed and maintenance and other factors have a direct impact on the use of picking effect. General asphalt pavement ordinary cut to meet the requirements, and cement pavement will use a higher performance of the pick, milling depth, milling power, load the greater the speed of the performance requirements of the higher pick. The proper design of the milling drum and the correct arrangement of the picks on the milling drum are also related to the life of the picks. However, as a drilling tool manufacturing enterprises, we can only grasp the reasonable structure of the cutting structure and manufacturing quality assurance, and the use of working conditions and the use of maintenance and other requirements can only make reasonable recommendations to the user, so understand the foreign milling The structural size of the cutting gear has a certain reference value to improve the performance of its own products. Sandvik has been constantly updating its design in the cutting structure, and the company's recent milling saw is shown in Table 4.
