A part's-eye view of a boring bar. Hole types: Blind hole (left), through hole (middle), interrupted hole (right). In machining, boring is the process of enlarging a hole that has already been drilled (or cast) by means of a single-point cutting tool (or of a boring head containing several such tools), such as in boring a gun barrel or an engine cylinder.
A lathe is a machine tool used principally for shaping pieces of metal, wood, or other materials by causing the workpiece to be held and rotated by the lathe while a tool bit is advanced into the work causing the cutting action.
Boring (earth), drilling a hole, tunnel, or well in the earth Tunnel boring machine, a machine used in boring tunnels; Boring (manufacturing), enlarging a hole that has already been drilled; Drilling, a cutting process that uses a drill bit to cut a hole of circular cross-section; Boring, a mechanism of bioerosion
Facing on a lathe (perpendicular to the axis of rotation), which is commonly used in turning and boring operations. Other operations remove material in ways similar to facing, for example, planing , shaping , and grinding , but these processes are not labeled by the term "facing."
The process of feature replication allows the flatness and squareness of a milling machine cross slide assembly, or the roundness, lack of taper, and squareness of the two axes of a lathe machine to be transferred to a machined work piece with accuracy and precision better than a thousandth of an inch, not as fine as millionths of an inch.
Modern metal lathe A watchmaker using a lathe to prepare a component cut from copper for a watch. A lathe (/ l eɪ ð /) is a machine tool that rotates a workpiece about an axis of rotation to perform various operations such as cutting, sanding, knurling, drilling, deformation, facing, threading and turning, with tools that are applied to the workpiece to create an object with symmetry about ...
CNC machine pouring coolant to keep the tool and parts from getting hot Lathe machine. Machining is a manufacturing process where a desired shape or part is created using the controlled removal of material, most often metal, from a larger piece of raw material by cutting.
The revolutionary underlying principle was that advances in machine tool control that expedited the making of jigs were fundamentally a way to expedite the cutting process itself, for which the jig was just a means to an end. Thus, the jig borer's development helped advance machine tool technology toward later NC and CNC development. The jig ...
