How to choose a suitable end milling cutter in processing?
A. Classification by Material
1. White steel milling cutter: also known as high-speed steel, it has soft and hard properties. High speed steel cutting tools are cheap and have good toughness, but their strength is not high, making them easy to cut. Their wear resistance and thermal hardness are relatively poor. The hardness is approximately 600 degrees. When using white steel to mill harder materials, if the coolant is not in place, it is easy to burn the tool. This is one of the reasons for the low thermal hardness.
2. Hard alloy milling cutter: Hard alloy (tungsten steel) has a series of excellent properties such as good thermal hardness, wear resistance, good strength and toughness, heat resistance and corrosion resistance. Especially, even at 500 degrees, the high hardness and wear resistance remain basically unchanged, and still have high hardness at 1000 degrees.
3. Ceramic milling cutter: also known as oxidation milling cutter, it has extremely high hardness, heat resistance up to 1200 degrees, compressive strength is extremely high, but brittleness is too high, so the strength is not high, so the cutting amount cannot be too large. Therefore, it is more suitable for final precision machining or other high wear resistant non-metallic processing products.
4. Superhard material milling cutter: it has enough toughness whether it has excellent hardness, wear resistance or heat resistance. Its temperature can withstand up to 2000 degrees because it is too brittle and not solid. More suitable for final finishing.
B. Classification according to the manufacturing method of end mills
1. Grinding blade: This type of blade has better dimensional accuracy, so the positioning accuracy of the cutting edge in milling is higher, which can achieve better machining accuracy and surface roughness. Grinding Inserts with large front corners can be used for milling viscous materials TCGT Insert such as stainless steel. Through the shearing effect of sharp Inserts, the friction between the blade and the workpiece material is reduced, and the chips can leave the front of the blade faster.
2. Pressing blade: It is best to choose a pressing blade for rough machining, which can reduce processing costs. The dimensional accuracy and sharpness of the pressed blade are worse than those of the ground blade, but the edge strength of the pressed blade is better. It has impact resistance and can withstand greater cutting depth and feed.
3. Combination blade: Install the pressed blade in the blade seat of most milling cutters, and then configure the polishing scraper blade to remove rough machining marks.

D. According to the cutting edge of the milling cutter
1. Flat bottom milling cutter: Machining Carbide Inserts also known as end milling cutter, smooth cutter, gong cutter, and purple cutter. They are usually used for precision machining, semi precision machining, precision machining, and milling cutter Inserts for machining flat surfaces, side planes, grooves, and mutually perpendicular step surfaces. The more numbers, the better the effect after completion.
2. Rough milling cutter: also known as wave edge cutter, used for rough machining of workpiece surfaces. According to the tooth profile of the wave edge, it is divided into coarse teeth, medium teeth, and fine teeth. Different tooth shapes result in different machining parameters. Generally speaking, this type of milling cutter allows for a large cutting amount, so roughening of the workpiece is the preferred choice.
3. Ball end milling cutter: Due to the spherical shape of the blade, it is called a ball end milling cutter, also known as a computer ball cutter or R milling cutter. It is usually used for semi precision machining and precision machining of various curved surfaces and curved grooves.
4. Round nose milling cutter: also known as cow nose milling cutter or rounded milling cutter. It is commonly used for processing right angle step surfaces or grooves with R angles, and is often used for semi precision and precision machining.
5. Copper aluminum milling cutter: mainly manufactured for the characteristics of copper aluminum materials. Its characteristics are large front corner, large rear corner (sharp teeth), large helix, and good chip removal effect. It is processed from copper and aluminum. Preferred.
6. T-groove milling cutter: mainly used for processing T-groove and side groove.
7. Chamfer milling cutter: mainly used for chamfering the inner holes and shape of molds. The chamfers are 60 degrees, 90 degrees, and 120 degrees.
8. Internal R milling cutter: also known as concave end milling cutter or reverse R ball cutter, commonly used as a specialized milling cutter for milling convex R-shaped surfaces.
9. Countersunk milling cutter: mainly used for processing hexagonal socket screws, mold thimbles, and mold nozzle counterbore holes.
10. Oblique cutter: also known as conical cutter, it is commonly used for ordinary blade processing, draft allowance processing, and conical surface processing after concave surface processing. The slope of the tool is the degree on one side.
11. Swallowtail groove milling cutter: Shaped like a dovetail, mainly used for machining dovetail groove contour workpieces.
