Embodiment Construction
[0012] refer to figure 1 It is an embodiment of a high-speed cutting cemented carbide milling cutter of the present invention, a high-speed cutting cemented carbide milling cutter, comprising a cemented carbide handle 1, a cemented carbide cutter head 2, and the cemented carbide cutter head 2 is set On the tungsten carbide handle 1, the tungsten carbide shank 1 is coaxial with the tungsten carbide cutter head 2, and the side of the tungsten carbide cutter head 2 is provided with a spiral sipe 3. There is a liquid flow hole 4 extending into the cemented carbide cutter head 2 in the handle 1, and the side wall of the cemented carbide cutter head 2 has a liquid outlet hole 5 that is the same as the liquid flow hole 4. The hole 4 is coaxial with the cemented carbide handle 1, the liquid outlet hole 5 is a straight through hole, the axis of the liquid outlet 5 is inclined downward, and the axis of the liquid outlet 5 is between the axis of the cemented carbide handle 1. The angle ...

The invention discloses a milling cutter for cutting a carbide alloy with high speed, which comprises a cemented alloy handle and a cemented alloy cutter head, the cemented alloy cutter head is arranged on the cemented alloy handle, the cemented carbide alloy handle and the cemented alloy cutter head are coaxially formed, a spiral cutter groove is provided at the side of the cemented alloy cutter head, a fluid hole which extends into the cemented alloy cutter head is provided in the cemented alloy handle, a liquid outlet hole which is same with the fluid hole is provided at the sidewall of the cemented alloy cutter head. The milling cutter for cutting carbide alloy with high speed has the advantages that a flowing coolant is capable of directly cooling the cemented alloy cutter head, so that the milling cutter can be cooled, the cutting speed is enhanced and the work efficiency is raised, simultaneously, the coolant from the fluid hole flows on the nearby work surface of the cemented alloy cutter head, so that the amount of the coolant is substantially reduced.
Description
technical field [0001] The invention relates to a high-speed cutting hard alloy milling cutter. Background technique [0002] A milling cutter is a rotating tool with one or more teeth for milling. When working, each knife tooth cuts off the allowance of the workpiece intermittently in turn. Milling cutters are mainly used for machining planes, steps, grooves, forming surfaces and cutting off workpieces on milling machines. [0003] Carbide flat-end milling cutters are mainly used for rough milling. When used for rough machining of large alloy forgings, the cutting volume is large. Because the usual cooling method is not easy to cool the cutter head, the cutting speed cannot be raised all the time, which affects the processing efficiency. And need to use a large amount of coolant, cause unnecessary waste. Contents of the invention [0004] The object of the present invention is to provide a high-speed cutting cemented carbide milling cutter, which can effectively solve ...
