A horizontal boring mill is an industrial machining tool use to create or enlarge the diameter of a pre-drilled or cast hole in large stock materials made of wood, metal, plastics, and more. Similar to the function of a lathe, the horizontal boring mill functions by turning either the stock or the tools. It is dedicated to interior shaping and excels with large and/or repetitive projects (unlike a lathe, which is primarily external though capable of internal boring on a small scale).
Machinery for boring has come a long way in its 250-year history. The horizontal orientation is used primarily for the big jobs. Large stock and parts, using a horizontal spindle, are turned parallel to the floor or work surface. This orientation makes the machinery and the turned part accessible to cranes and other lifting apparatuses for safe machining and transport.
Horizontal boring mills are available in table, planer, and floor types. Table boring mills are the most common, and are also called “universal” because of its versatility.
General Features of Horizontal Boring Mills
- Heavy duty industrial cutting capability, often with steel or carbide cutting tools
- High precision and repeatability
- Straight or tapered cutting
- Capable of full-length bores on stock several meters/yards long (depending on the specifications of the particular mill)
- Bore diameters up to several inches
- Computer control options (CNC)
- Horizontal orientation with a variety of bore angles
- Floor, planer, or table-top (“universal”) configurations
- Actual specifications vary by model
