If the cutting depth and feed rate is too large, it will increase the cutting resistance, but also accelerate the wear of tungsten carbide milling cutter. Therefore, choosing the right amount of cutting can also prolong the service life of tungsten steel milling cutter.
A larger front Angle results in smaller chip deformation, lighter cutting, lower cutting resistance, and lower cutting heat. The front Angle should be as large as possible on the premise of ensuring sufficient strength of the tungsten steel milling cutter.
Reducing the entry Angle will increase the length of the cutting edge involved in cutting, so the relative distribution of cutting heat and the increase of the cutting Angle may reduce the cutting temperature.
If the tungsten milling cutter is abnormally worn or has a falling edge that leads to rapid wear, the tool should be selected and the cutting parameters changed. To increase tool strength, it is also effective to use a negative front Angle geometry while selecting a fine hard alloy material with high hardness.
The modification of cutting conditions is to first reduce the amount of cutting rather than drastically reduce the feed speed. In order to maintain the wear resistance of a tungsten mill and obtain a good surface finish, it is important to choose high rather than low cutting speeds. Reduce cutting amount and realize stable machining by high speed milling machine.
Through vibration analysis and other parts of the cutting conditions, timely adjustment, for tungsten steel milling cutter to prepare the working environment. After replacing the tungsten steel milling cutter, adjust the dimensions to ensure proper tightening and cutting conditions.
