The Definition of Boring Milling Machines

Boring is a technical machining process where existing drilled holes are resized and reshaped. The process involves the use of single-edge cutting tools or equipment with uniquely adjustable boring heads. In advanced machining, boring facilitates create precise holes with the right diameter. In industrial scale operations, accurate machinery is an important aspect of the facility.

Therefore, boring milling machines offer efficiency and high-functionality:

Conventional boring contains two types of processes. The first process is called line boring, a process where surface holes are precisely created through one single facet of the material. The second type of boring is referred to as back boring, a process where the hole is enlarged from either end of the material.

Since the creation and expansion of surface holes depends on the direction from which the holes are bored, boring milling machines come in different shapes, designs and operational capabilities. The boring tools on each of the distinct classes are fitted on the rotating spindle, and can be altered to match various user’s specifications. Common classes of boring machines include:

  •        Vertical boring machines
  •      Horizontal boring machines
  •      JIG boring machines

Since the machines are designed for varied operational specifications, holing is accomplished through different types of approaches. Below are some approaches that can be used in both industrial and non-industrial scales.

  •     Lead screw hole locating method
  •     Mechanical gauging method
  •   Electrical gauging method
  •    Optical gauging and measuring method

Industrial scale boring milling machines are designed to achieve three objectives as outlined below.

  •   Sizing of holes: First, is the sizing effect, which allows users to expand pre-drilled holes into different sizes. This is primarily guided and determined by the size of drilling bits used in expanding the holes.
  •   Straightness of holes: Initially cast (drilled) holes can be precisely straightened through various boring machines.  
  •   Concentricity: Boring allows for the creation of concentric holes with the exterior diameters being set to user-specific limitations.
