A horizontal boring mill is a machine for making cylindrical holes in a variety of materials, such as metals, plastics, and concrete. It consists of a table with a rotating spindle that makes holes with a series of cutting tools that are mounted on a horizontal arm.
All horizontal boring mills have extensive applications, and here are five of them below.
Crane
Holes in cranes and towers are needed to pass the ropes and chains that connect the 50 tons of steel used in construction. These holes must be faithful to their blueprint to produce accurate and reliable results. Horizontal boring mills are always up to the task when it comes to crane manufacturing.
Tunnel Walls
The horizontal boring mills create tunnel walls by using a continuous stream of material to be cut called a "spiral cut." The spiral cut is formed by the cutting teeth rotating at high speed and the friction created by the spinning cutter head and cutting material. Only well-maintained horizontal boring mills can achieve these project results.
Enlarging Existing Holes
Horizontal boring mills enlarge existing holes in components by using a diamond-edged cutting tool to remove material. The tool moves vertically, and the rotary motion of the tool is converted into horizontal movement by a lead screw.
The lead screw moves the tool at a constant speed and feeds the material removed from the hole down a series of inclined planes that move the material evenly and deliver it to a horizontal boring bar which moves horizontally and enlarges the hole.
Engine Cylinders
Horizontal boring mills create accurately sized cylinder holes by using a precise conical cutter to remove material. The conical cutter is used in conjunction with a shoe that is attached to the milling machine table. The shoe has a circular cutting edge that rotates around a central axis. It cuts the cylindrical groove around the circumference of the piston at a specific depth from the top of the cylinder base.
Assembly Specs
Horizontal boring mills greatly contribute to the assembly process of metal fabrication. They are used for cutting sheet metal into various shapes that can then be assembled with other pieces of sheet metal.
