Line Boring


Line Boring, which can also be referred to as Line Boring, is a term used to describe an engine machining process. The aim here is to create perfectly straight and aligned holes. These are used for the camshaft housing, also known as calipers and tunnels, and for the crankshaft. When it comes to any of the steps in this process, in-line boring is perhaps the most important step in the entire engine block design process.

What Is a Drill used For?

The use of a line drilling machine is very specific. It is designed to enlarge an existing hole, usually by pouring and drilling beforehand. This is one of the tools used to cut the component. There are various cutting tools that can be used within the machine to achieve this result. These are made with a drill head.With the right tools, it is possible to produce a highly accurate and precise end product. The hole diameter is enlarged and there is high precision.

The term line drilling is often used in the machining industry, but not everyone is familiar with this common practice. Line drilling is required for many machining and repair projects and can range from simple procedures to complex situations that require months of work and the dedication of many engineers.

A line drilling job often depends on the complexity of the machine, the number of holes and how damaged or worn a hole may be.Simple repairs can sometimes be completed on site in a few hours. However, there are many instances where engineering designs as well as custom drill rod systems need to be requested. These larger projects can take several technicians and sometimes months.

In-Line Drill


An in-line drill is used to enlarge an already drilled or cut hole with one or more cutting tools held in a drill head. As a result, the operation achieves greater accuracy of the hole diameter.Linear boring machines are used on a wide variety of projects, some common examples include:

Excavator buckets
Transfer case housings
Stern tubes and rudder bores in the shipbuilding industry
Drive shaft housing bores
A-frame supports
Hinge pins
Gearboxes
Turbine housings in power generation
As well as machining parallel bores, line boring machines can also be used to taper bores and to machine the outer surface of the workpiece with a face head.
