Boring operations are performed to enlarge a pre-drilled hole. After the hole is enlarged with the rough boring process, fine boring operation is carried out to bring the hole to its final tolerance and give it a high-quality surface finish. Fine boring tools of large and small diameters as well as certain tools with dedicated diameters are used for the process. Various technological developments have now made fine boring more accurate while reducing vibrations.

Purpose and advantages of fine boring tools

Finishing hole with tight tolerances requires tools that can be adjusted for accuracy in small measures-a capability that fine boring heads readily offer. Businesses rely heavily on precision finish boring tools to meet their customers’ requirements. Finish boring is the best fit for short-run jobs and in situations where there is a lot of stock left in the hole. Finished boring is a quite flexible process which enables operators to machine different hole sizes using the same tool. Additionally, if a machine tool has lots of runout at the spindle, the boring head can be adjusted to compensate for such runout. This feature offers fine boring considerable advantage over other hole-finishing processes such as reaming.

Factors to be considered during the fine boring process

  • Hole diameter and length
  • Interruptions within the cavities
  • Required straightness
  • Size and tolerance of the hole
  • Surface finish of the hole.

Digital technology is now helping fine boring heads offer the highest performance and accuracy. In addition, there are a wide number of replicable insert holders to choose from. Choosing the right tool set is the key to getting your diameter and depth right.
