Carbide milling cutter

            Hard alloy milling cutters have high hardness and are not easily worn. They are generally used in CNC machining centers and CNC engraving machines. It can also be installed on the ordinary milling machine to process some hard and uncomplicated heat treatment materials. The carbide milling cutters are widely used and use high speed machining.

Features

            arbide cutting tools (especially indexable carbide cutting tools) are the leading products of CNC machining tools. In some countries, more than 90% of turning tools are used, and more than 55% of milling cutters are made of carbide, and this The trend is still increasing. Since the 1980s, the tool industry has continued to expand the production of various solid and indexable carbide tools or inserts. Its variety has been extended to various cutting tool fields, among which the indexable carbide tool is simple. Turning tools and face milling cutters have expanded into various precision, complex, and formed tooling fields. Carbide is also a common material used to make general-purpose tools such as drills and face mills. At the same time, the use of carbide for complex tools such as taps, reamers, end mills, hard-toothed medium- and large-modulus gear tools, broaches, etc. is also increasing.

application

           When the carbide milling cutter performs the milling operation, the workpiece can be fed in or against the direction of rotation of the tool, which affects the starting and finishing characteristics of the cutting.

            When the carbide milling cutter performs chui milling (also called co-rotating milling), the workpiece is fed in the same direction as the carbide milling cutter in the cutting area. The chip thickness gradually decreases from the beginning, until the end of the cut is zero when performing peripheral milling; in the case of up-cut milling (also called reverse milling), the feed direction of the workpiece and the milling cutter rotation of the cutting area The direction is just the opposite. The chip thickness begins to zero and then gradually increases as the cutting process progresses.

             When carbide milling is used for up-cut milling, carbide cutting inserts begin cutting at zero chip thickness, which creates high cutting forces that drive the carbide milling tool and workpiece away from each other. Carbide milling cutter blades are forced into the incision and are usually in contact with the machining hardened surface caused by the cutting insert while generating friction and polishing effects due to friction and high temperatures. Cutting forces also make it easier to lift the workpiece from the table.

           When the carbide milling cutter is milling, the carbide milling cutter starts cutting at the maximum chip thickness. This can be avoided by lowering the heat and weakening the machining hardening trend. Applying the maximum chip thickness is very advantageous, and the cutting force makes it easier to push the workpiece into the carbide milling cutter for the cutting action of the carbide milling cutter blade.

            When the carbide milling cutter is milling, chip breaking sometimes sticks or welds to the cutting edge and it will gather around the beginning of the next edge cutting. During up milling, the chip breaking is easier to trap or wedge between the blade and the workpiece, which can cause the blade to crack. In the case of crush milling, the same chip breaking is split in two so that it does not damage the cutting edge.
