Operation of the horizontal boring mills is quite simple. The work-piece revolves round a horizontal axis on a vertical table. A horizontal spindle is used to drill into the work piece. The boring bars have two degrees of movement: rotary and lineal into the work piece. The drive mechanisms are held in place by the base. They are used to transfer motion to the spindle and vary its rotary speed as well. They are composed of belt drives and gears systems.
In most designs of the horizontal boring mills, boring bars are held in place by support ends. The supports allow them to rotate and move transversally. The spindle is usually supported by the column. The column allows it to move in various directions during operation. Most operations carried out by the boring machines are computerized. The operator feeds an in-built computer with various settings and runs the machine using these settings. This means minimal supervision and reduced labor as well. These settings can be used to achieve very accurate designs with minimal errors.
Various axes are used to describe the operation of horizontal boring mills. The main axis in which the Z axis. The X and Y axis traverse the main axis perpendicularly. The spindle rotates on a C axis while the table is positioned along the B axis. This convention is used by most engineers to describe the machine’s operation. The floor type horizontal boring machines are used to produce big holes quickly but with a rough surface finish. However, some industries are coming up with improved models which can work on larger holes with high precision and perfect surface finish. The CNC systems have made high precision possible for each of these machines. Therefore, industries can invest on the CNC controlled models for better output.
