1) The material does not require high linear speed: as we said above, when processing red copper, aluminum alloy and other materials, the version should be processed with a flat-bottomed knife. 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.

1. Key points of grooving: radial rake angle, core thickness, helix angle, groove length, cylindrical toughness bandwidth, grinding wheel fillet, groove type requirements, etc.

2. Key points of the circumferential edge: radial relief angle, blade diameter, blade length, circumferential blade width, radial jump, inverted taper

3. Key points of the end edge: end rake angle, end relief angle, end kernel width, edge inclination, end jump

4. Key points of backlash: chisel edge, over-center amount, backlash angle, tooth expansion and exit, bottom corner arc, fusion depth, fusion angle, wheel selection, ball head slotting rake face length

5. Other key points: ball head, arc, taper, chamfer, incision, height removal, forming contour, passivation, appearance, etc.

Diamond bit

The drill with the cutting edge is called a diamond drill. The drill bit is an integrated drill bit, the whole drill bit has no moving parts, the structure is relatively simple, and it has high strength, high wear resistance and impact resistance. It is one of the three new drilling technologies in the world in the 1980s. Field use has proved that when drilling in soft-medium-hard formations, diamond bits have the advantages of high speed, large footage, long life, stable work, fewer downhole accidents, and good well quality. Diamond drill bits are not only used for a long time, but can also be reused. The use effect of the returned diamond drill bit is similar to that of the factory diamond drill bit, which can save a lot of drilling costs.
