Before knowing about portable line boring equipment, you should first know basic information about the technical terms such as boring machine and line boring.
A boring machine is special equipment for processing deep hole workpieces. Boring machines can be divided into different types according to their application and structure.
Line boring machines
Horizontal boring machines
Tunnel boring machines
Coupling boring machines...
A line boring machine is designed to make larger and more accurate holes that have already been drilled. A line boring machine is usually composed of a boring bar, a point cutting tool, bearing seats, a motor, and so on. Most line boring machines on the market can manufacture parallel bores and process deep hole workpieces. Line boring machines can be electric or hydraulic.
And portable line boring equipment is very popular in the industry for its accuracy, safety, and convenience.
Line boring is in essence an enlarging hole that has already been cast or drilled to align the centerlines of two or more bores. Line boring can be divided into rough boring, semi-finish boring, and finish boring. The dimensional accuracy of fine boring can reach IT8~IT7, and the surface roughness Ra value ranges from 0.8 to 1.6 μm.
Boring is divided into common size hole boring and deep hole boring. Common size holes can be processed on a normal lathe by fixing the boring tool on the tailstock of the lathe or a small tool holder. Deep hole boring requires a special boring machine that needs to be paired with boring stalk and a hydraulic pump station to remove the iron chips.
Portable line boring equipment is an on-site machine that can help make the rough holes more accurate and larger.
When the portable line boring equipment works, the internal chip removal method or external chip removal method is adopted. The machine bed features strong stiffness, outstanding accuracy retention, and a wide range of spindle speeds.
The feeding system is driven by an AC servo motor that can meet different needs of hole drilling and machining. The oil feeder is fastened and the workpiece is tightened by hydraulic devices, and the instrument display is safe and reliable.
Portable line boring equipment is composed of several parts that are easy to operate and carry around.
Portable line boring equipment has three different machining methods:
The workpiece rotates and the tool makes a feed motion on the lathe to bore. This machining method is suitable for processing holes with coaxiality requirements on the outer surface.
The tool rotates and the workpiece makes the feeding motion.
The tool rotates and feeds the workpiece. The length of the boring bar varies, and the force on the boring bar also varies. This is only suitable for making small-sized holes.
Compared to regular line boring machines, portable line boring equipment can be more small-sized, light, and compact, but it can also meet the needs of processing. So, it is applied in many fields.
Portable line boring equipment can boring the cylinder bores and cylinder liner bores of internal combustion engines such as automobiles and tractors, as well as for precision boring of the bores of other mechanical parts. It cannot only machine the surface but also process the outer face of the workpieces. It can make accurate holes on backhoes, tractors, excavators, scrapper hitches, etc. It is designed for machining following repair welding of rotary holes, hinge holes, and shaft pin holes on various engineering machinery structures.
