It is not necessary to use G83 for drilling on CNC milling machines. Generally, G81 is used when water is added. It is recommended that the best G81, CNC car use G01 the best instructions, which means which. No worries.

Compared with the integral drill, the U-drill is a tool that performs hole machining by combining a center blade (inner edge) and an outer periphery blade (outer edge). This structure determines that the U-drill has an irreplaceable advantage over other drilling tools.

Don't use g83 for U-drills (the kind of cyclic commands for drilling a little bit back), the debris is all in the hole, up and down, directly hitting it ... the hole is not deep, g81 is done. The blade is changed frequently.

The U-drills are all internally cooled. Without internal cooling, the twist drill is easy to use. The twist drill works with the macro program I wrote before, and the speed will not be slow. Section 49. Macro program of deep hole drilling imitating G83 (CNC car must pay attention to this, internal cooling is very important)

U-drills are usually processed from the outside to eat knives. Compared with the center-drilled form, U-drills are more suitable for machining. (The following are common U drill applications)
