What is line bore?
Line boring is essentially enlarging a hole that has already been cast, making the centerlines of two or more bores collinear. Collinear bores appear in several large machine parts such as engine blocks, gearboxes, presses and turbines.
What is portable line boring?
Portable Line boring is an on-location welding/machining process to repair bores that have been worn out, oversized or irregular shaped. We are able to build up the inside diameter of the bore with a robotic welding system and machine back to OEM specs.
What is line boring used for?
Line boring, which can also be called align boring, is a term used to describe an engine machining process. The task involved here is to create perfectly straight and aligned bores. These are used for the camshaft housing, which is also known as the saddles and tunnels, as well as the crankshaft.

Can you bore out an engine?
There are only two ways to increase an engine’s displacement: You can bore it (engine boring increases the cylinder diameters) or you can stroke it (engine stroking increases the crankshaft stroke).
What must be done when correcting a main bore alignment issue?
The cure is to check the alignment of the bores and the straightness of the crankshaft (one or both may be off). A bent crank should be straightened or replaced. If the bores are off, the main caps can be cut down so the bores can be bored or honed to restore alignment and size.
What are the examples of boring tools?
The Different Types of Boring Tools
- Solid boring bars. Typically made of carbide for finishing or heavy metal for roughing, solid boring bars have dense structures that make for a more stable cut as axial force is applied.
- Damping bars.
- Rough boring heads.
- Fine boring heads.
- Twin cutter boring heads.
- Digital boring heads.
