When we hear the word “boring,” we think about a state of mind and not a procedure relates to custom CNC machining. While the term is widely known for its collective meaning “boring” is actually one of the most used techniques to handle machining task centered on offering flawless finishes to holes. To be more specific, boring is a process used to enlarge and finish pre-existing holes on a surface. These holes have been previously cast, drilled or formed by other means, but boring is what shapes them into an evener final form according to the specs of the project.
Types of CNC boring
Boring can be explained using several markups for all the subtypes that exist right now. They are commonly identifiable by the tools used to create a hole. We have through-hole boring which is used when the piece that is being worked on has to be supported on both ends of the shaft to fall underline boring. Blind boring is also used to finish blind holes, when the workpiece is supported on one end. Back boring is used to handle traverse cuts through a hole that works on the side of the piece that is opposite to the headstock.
Recommended Tooling for Boring
Boring is performed using rotating CNC machines such as turning centers and milling centers. There are also a few tools that are very specific to the tasks of boring that have been released to the market, such as horizontal machine support for a piece that is being tooled on a perpendicular axis that it also works for rotating cuts. You can also find jig borers to locate the center of a hole in a surface before removing any material. Complex operations call for dual-point cutting tools. In these occasions cutting surfaces are opposites of each other. Working on these types of tasks demands higher tolerances, so a single-point cutting tool is used. All these tools are handled using turning centers, milling centers, or specialized boring machines.
Moments When Boring is Required on CNC Machines
The general purpose of boring is to reduce tolerances and to increase precision on large shipments of machined products. Boring as a procedure is highly regarded for being incredibly accurate, but it is not the best means to get rid of excess material. If a set of holes have not been punched on a surface yet, the best way to go is with classic drilling before using boring. If you need medium tolerances for a job, traditional milling or turning are preferably before refining the piece with boring procedures.
