The Ranges of Boring Processes

Generally, the process of boring makes a drilled or cast hole larger with a single boring head or point cutting tool. The hole is first drilled to create the initial hole in a part and then boring enlarges the existing hole utilizing awls, gimlets, and augers. The basic tool for making a hole in a part is an awl, which pushes material to one side without removing it. Other tools used in the process include drills, gimlets, and augers. These tools have cutting edges that detach material to create the hole. The following are the range of the types of boring.

Jig Boring

The jig boring process is used when a hole needs to be a precise diameter and location. Utilizing a vertical jig boring machine, the operator can make exact adjustments to the cutting tool position within tolerances of ±.005 mm or ±0.0002 inches.

Vertical Boring 

Most often used for large holes, vertical boring uses a rotating piece attached to a horizontal table. Additionally, vertical boring mills can perform turning, facing, tapering, and cutting of both internal and external threads.

Horizontal Boring

There are three main types of horizontal boring: table, planer, and floor. The most common and versatile is the table type. Horizontal boring produces a highly accurate cylindrical surface while enlarging the existing opening. The drilling and milling work is done on a horizontally clamped workpiece with a movable column carrying the spindle headstock with the workpiece receptacle. 

Line Boring

Line boring, is also known as align boring. It is a machining process utilized when a perfectly straight and aligned bores are required.
