Turning knives

　　No matter what knife you choose, you must know:

　　What is the material of processing? What machine tool is used for processing? Finishing or roughing? Are there any drawing requirements? What is the compression method? How many knife squares? Blade model?

　　1. Cylindrical turning tools:

　　What degree is the main declination angle of the tool required? Are there any drawing requirements? What is the material of processing? Are there any hardness requirements?

　　2. Inner hole turning tools:

　　What is the diameter? How deep is the hole? What is the inner diameter of the machine tool sleeve? Is there any interference with the inner hole?

　　3. Grooving knife:

　　How deep should you cut? How wide is the groove? Is it an outer round groove or an inner groove cutter? What is the maximum and minimum machining diameter? (End face groove knife special question)

　　4. Cutting knife:

　　What diameter to cut? What is the required groove width?

　　5. Thread turning tools:

　　Threaded turning tool forehand and backhand? External or female? Metric or imperial? What is the pitch?

　　Knife clips

　　Milling cutters: (taking machining center as an example)

　　Do you want a table or digital display, or a projection? What is the range of measurement? What is the measurement accuracy?

　　Knives

　　One. Milling cutter:

　　1. Integral milling cutter

　　Do end mills want high-speed steel or carbide? What is the hardness of the machining? Less length requirements? How many blades? Ball head or flat head? How many degrees is the shank? How many threads? What kind of coating? How many degrees is the spiral rise angle?

　　2. Blade milling cutter

　　1) Mandrel milling cutter

　　What is the required diameter? Is there a requirement for the angle of the blade? What is the length of the process?

　　2) Cutterheads;

　　What diameter? What is the required angle of the blade? Finishing or roughing? Is there a requirement for knife clearing?

　　Two. Drill bit:

　　1) Straight shank drill bit

　　Is the drill bit required to be high-speed rigid or carbide? What is the machining diameter? What is the depth of processing? Are there any requirements for the blade?

　　2) Taper shank drill bit
