The difference between two-flute milling cutter and three-flute milling cutter — different precision requirements:

1. The size of the keyway milled by the two-edge milling cutter can reach high precision, and the end face of the keyway milling cutter has no center hole, and it can be directly fed downwards, instead of the ordinary three-edge milling cutter due to the center. The center hole can not be directly fed downwards.

2. The keyway milling of the end mill of the three-flute milling cutter can’t reach the precision of the keyway milling cutter. When these two types of milling cutters are milling, there is no difference in the three elements of milling.

The difference between two-flute milling cutter and three-flute milling cutter—the two functions are different:

1. The two-edged milling cutter is a keyway milling cutter. The keyway milling cutter is named after the keyway milling cutter. It is a fixed-size prop. If it enters the tool directly, it will be held up by the center hole and break Knife accident. Instead, the knife can only be entered from the side, or while the knife is moving, the knife can be entered.

2. The three-flute milling cutter is an ordinary end mill, and the outer diameter of the milling cutter does not have the same precision requirements as the keyway milling cutter.

How should the flat-bottomed sharp knife of the CNC engraving machine be used?

1) The material does not require high linear speed: as we said above, flat-bottomed knives should be used when processing copper, aluminum alloy and other materials. This is because this type of material does not require very high linear speed during processing, and the effect of linear speed on tool life is not very obvious. At this time, we use flat-bottomed knives for processing.
2) During finishing, some positions need to be processed with flat-bottomed knives: the accuracy of self-grinding bull nose knives is generally difficult to guarantee, so finishing cannot be performed. The accuracy of flat-bottomed knives is relatively better guaranteed.
In addition, flat surfaces, vertical walls and intersections at right angles can only be processed with flat-bottomed knives.
