What is line boring machine
The line boring machine is used to enlarge a hole that has been drilled or cast using one or more cutting tools fixed in the boring head. Doing so can make the accuracy of the aperture higher
If the holes in the machined part are not collinear, it may cause misalignment, vibration or even system failure. If a small amount of misalignment is introduced, usually the machine cannot work at all. This is why this type of repair is so common.
Common Applications on line boring machine
Line boring machines are used on a wide range of projects, with some common examples including:
Excavator buckets
Transfer gearbox housings
Stern tubes and rudder bores in the shipbuilding industry
Drive shaft housing boring
A-frame supports
Hinge pins
Gearboxes
Turbine casings in the power generation industry.
Our 7 Types of Line Boring machine
Our line boring machines support boring diameters from 1.375 to 80 inches (35 to 2030 mm), with the precision and speed of stationary machines. Specially designed mounting brackets, spherical bearings, self-centering setup cones, and movable rotational drive and feed units simplify setup and allow the tools to work in spaces too tight for most line boring machines.
All models feature rugged rotational drive and axial feed systems, precision bars and heavy duty bearings, with electric, pneumatic and hydraulic options. They have the ability to share the same mounting system with Auto Bore Welding Systems for single-setup machining and welding.
