In this tutorial, we will look at the drilling process. In this case, an internal cylindrical (conical) surface is formed by means of the middle tool, which must be located coaxial with the axis of rotation of the tool. The drilling is applied to obtain holes in a dense material.
Holes with a diameter of up to 30 mm are drilled directly, and holes with a larger diameter are initially drilled with a smaller diameter. Drilling holes can be done on various machines, such as drills, cutters or lathes. For more information on drilling, contact the library.
