What is deep hole drilling and what are its difficulties?

Deep hole drilling is the process of machining holes ten times deeper than the hole diameter. The main challenges with deep drilling are the efficient coolant control and metal chips removal. Failure involve a waste of time and material.

What is BTA tool?

BTA stands for Boring and Trepanning Association, and is also sometimes referred to as STS (single tube system) drilling, as it uses one single drill tube for the BTA tool, compared to other processes such as ejector drilling, which use two.

What is the reason for holes in drilling?

The main cause of rough holes during drilling is. feed rate is too high.

When depth of drilling hole exceeds it’s diameter called as deep hole drilling?

Deep hole drilling is defined as drilling a hole of depth greater than ten times the diameter of the hole. These types of holes require special equipment to maintain the straightness and tolerances. Other considerations are roundness and surface finish.

Which tool is used for deep boring?

The single-point cutting tool for boring operation is the Boring cutter. The boring process can be executed on various machine tools, including lathes (turning centers) or milling machines.

Which type of drill is used for deep hole drilling?

When drilling deep holes on a conventional CNC machine tool, there are three main options: a spade drill, a twist drill and a gundrill.

What is the name of the tool for boring holes?

Drills
A hole may be drilled or bored; awls, gimlets, and augers also produce holes. An awl is the simplest hole maker, for, like a needle, it simply pushes material to one side without removing it. Drills, gimlets, and augers, however, have cutting edges that detach material to leave a hole.

What are drilling tools?

Drilling tools are end-cutting tools designed for producing holes in a workpiece. The shank of a drilling tool incorporates flutes, or grooves, that allow for the entrance of fluids, along with ejecting the cut ships from the workpiece.

Why is speed important in a drilling operation?

Cutting speed is one of the most important factors that determine the life of a drill. If the cutting speed is too slow, the drill might chip or break. A cutting speed that is too fast rapidly dulls the cutting lips.
