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.
Unfortunately, the car, a giant six cylinder touring car, proved too costly to produce profitably and the idea was dropped. [3] In 1906, Neil C. Hurley, Sr., and his brother, Edward Hurley, formed the Hurley Machine Company. Their initial product was the first electric washing machine in the world, the Thor washing machine.
These cylinder-boring operations can be done in almost any engine shop and at low cost. An engine machine shop provides the most inexpensive and accurate machine work commonly done anywhere and guarantees that the spindle and overarm will be perfectly aligned and at an exact right angle to the face (head surface) of the main engine block that ...
James Watt was unable to have an accurately bored cylinder for his first steam engine, trying for several years until John Wilkinson invented a suitable boring machine in 1774, boring Boulton & Watt's first commercial engine in 1776. [8] [9] The advance in the accuracy of machine tools can be traced to Henry Maudslay and refined by Joseph ...
His development of a machine tool for boring cast iron cannons presaged the accurate boring of cylinders for the first Watt steam engines. He also improved the air supply for the blast furnace using a new design of bellows , and was the first to use wrought iron in canal barges.

The machine cost $1.5 million to construct and was named after the company president at the time, Stan Anderson, who was given a similar nickname due to his height of 6 ft 3 in (1.91 m). [1] The rig was originally built to meet the demand for a more powerful mobile drilling rig, specifically a demand for rigs capable of boring up to 260 feet ...
It resembles a specialized kind of milling machine that provides tool and die makers with a higher degree of positioning precision (repeatability) and accuracy than those provided by general machines. Although capable of light milling, a jig borer is more suited to highly accurate drilling, boring, and reaming, where the quill or headstock does ...
