The choice of cemented carbide circular blade as the tool for rough machining of dies

Cemented carbide circular blade, called "wafer", is one of the series of hard alloy materials. It is usually used to make hard alloy blades and hard alloy tools, such as hard alloy woodworking tools, carbide cutting machine blades, hard alloy V-CUT knives, hard alloy cutting tools, hard alloy paper cutting knives, hard alloy cutting tools, hard alloy cutting tools, hard alloy cutting tools, and hard alloy cutting tools. Quality alloy hob, carbide circular knife, carbide milling cutter, carbide saw blade, cemented carbide split knife etc. Its application field involves various fields of national production, such as special cutting tools in the electronic industry, special cutting tools in woodworking furniture industry, special cutting tools in hardware machinery processing industry, and the characteristics of hard alloy wafers that are also resistant to corrosion and acid alkali and are not rusty by the food processing industry. With cutting tools, in short, the application range of cemented carbide wafers is very extensive. It is a good assistant material for people's production and processing.

If a shoulder milling cutter is used for rough milling of the cavity, a large amount of step cutting allowance must be removed in semi finishing. This will change the cutting force and make the tool bend. As a result, uneven machining allowance is left to finish machining, thus affecting the geometric accuracy of the die. If the blade tip milling cutter with a weak tip is used (with a triangular blade), it will produce an unpredictable cutting effect. The triangle or diamond blade can also produce greater radial cutting force, and because the number of cutting blades is less, they are poor economiccutting tools.

On the other hand, the circular blade can be milled in all kinds of materials and in all directions. If it is used, the transition between the adjacent tool paths is smooth and a smaller and more uniform machining allowance can be left for semi finishing. One of the characteristics of a circular blade is that the chip thickness they produce is variable. This enables them to use higher feed rates than most other blades. The main deflection angle of the circular blade changes from almost zero (very shallow cutting) to 90 degrees, and the cutting effect is very smooth. At the maximum depth of cutting, the main deflection angle is 45 degrees. When the straight wall profile is cut along the outer circle, the main deflection angle is 90 degrees. This also explains why the strength of the circular blade tool is large -- the cutting load increases gradually. Rough and semi rough machining should always be the first choice for round blade milling cutters, such as CoroMill 200 (see mold manufacturing sample C-1102:1). In 5 axis cutting, the circular blade is very suitable, especially without any restrictions.

By using good programming, the circular blade milling cutter can largely replace the ball end milling cutter. The small circular blade with small pulsation is combined with the fine grinding, positive rake and light cutting groove. It can also be used for semi finishing and some finishing.
