Enlarging a hole that already has been drilled or cored. Generally, it is an operation of truing the previously drilled hole with a single-point, lathe-type tool. Boring is essentially internal turning, in that usually a single-point cutting tool forms the internal shape. Some tools are available with two cutting edges to balance cutting forces.
Cone-shaped pins that support a workpiece by one or two ends during machining. The centers fit into holes drilled in the workpiece ends. Centers that turn with the workpiece are called “live” centers; those that do not are called “dead” centers.

computer numerical control ( CNC)
Microprocessor-based controller dedicated to a machine tool that permits the creation or modification of parts. Programmed numerical control activates the machine’s servos and spindle drives and controls the various machining operations. See DNC, direct numerical control; NC, numerical control.
Kennametal Inc. has developed a 3D-printed Stator Bore Tool to meet growing customer demand for lighter weight tooling solutions used to machine components for hybrid and electric vehicles. E-mobility components are typically machined on small, low-horsepower CNC machining centers that require lighter weight tooling solutions. Kennametal’s 3D printed stator bore tool weighs half that of the conventionally manufactured version, while still meeting accuracy, roundness and surface finish requirements for aluminum motor body boring
