Q:What drill is used for punching aluminum parts?
Aluminum alloy, copper, stainless steel, these materials are not high hardness, aluminum alloy, copper soft, frequent drilling process, it is easy to have cutting, there will be a lot of burrs, aluminum alloy special drill.
Q:What kind of drills are commonly used in CNC machining centers?
There are many kinds, mainly depending on what parts you use to process, and the machine tools are good enough. Can you use high efficiency drills?.
Q:What bits of percussion drills are made of?
Features: with high hardness, strength and toughness, good wear resistance, heat resistance, corrosion resistance and a series of excellent performance, especially high hardness and wear resistance of it, even at a temperature of 500 DEG C also remained unchanged, at 1000 degrees C still have high hardness.
Q:What's the angle of a standard twist drill?
If the front angle is too small, the bit strength decreases, the deformation increases, the torque increases, and the drill bit breaks easily. Therefore, a reasonable front angle should be sharpened according to the strength and hardness of the workpiece material. The front angle of the standard twist drill is 2 and phi is 118 degrees
Q:How do you tell which materials are used in the test?
