What is line boring machine and how it works
A line boring machine is a tool that creates clean and accurate holes that have been already cast or drilled. The tooling head itself will consist of a single point cutting tool. Equally, equipment can be designed and manufactured to have a grinding wheel, dependant upon application. However, our line boring machines don’t only machine parallel bores; they can cut tapered holes or machine the surface of a workpiece using a facing head.
In the case of a single point tool, the tooling head will be secured in a rotating spindle (Boring Bar). The tooling head will move in a circular motion around the diameter of the existing hole to accurately increase the size. On some machines, the margin of error is less than 0.002%. Usually, a line boring machine will be hydraulic, but they can also be pneumatic or electric.
Portable line boring machine is a special equipment for processing oil cylinders, cylinders, and hydraulic cylinders with deep holes. It can also process spindle holes, blind holes and stepped holes of machine tools. The machine tool can not only undertake all kinds of drilling and boring, but also can carry out rolling processing. When drilling, the internal chip removal method or the external chip removal method is adopted.
Portable line boring machine Applications:
Processing and repairing of shaft pin holes, slewing holes, connecting holes of the main arm, and lifting ring holes on various construction machinery and after welding. The processing and repair of concentric holes and multiple rows of holes on construction machinery such as presses, loaders, and cranes, and one-time positioning and installation can ensure the concentricity of multiple holes.

How to choose the suitable portable line boring machine?
You could share your situation on site with our company, we will provide the suggestion after evaluating with our engineer.
Normally we will need to know the details of the workpieces, such as the boring diameter, the length of the holes, depth of each hole, pictures of workpieces. With CAD or other drawing of details are both helpful.
