Chucking reamers, or machine reamers, are the most common type of reamer used in lathes, drill presses, and screw machines that provide a smooth finish to the hole. They come in a variety of flutes and cuts (e.g. right hand cut, left hand spiral, straight flute) as well as different shank types.
A bead roller is a machine tool that makes rigid lines in sheet metal to make surfaces more rugged and durable. The lines bead rollers add to sheet metal prevent ...
Currently R8 and Erickson #30 Quick Change tool holders are available. Machine slides are of the dovetail type, and rotary bearings are mostly of the roller and ball types. Through 1970, Bridgeport turret milling machines were made under licence by Adcock-Shipley, a UK manufacturer of horizontal and vertical milling machines founded during WW1.

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.
The bead is a thicker section of rubber, and is reinforced with braided steel cables, called the bead bundle. [1] The surface of the bead creates a seal between the tire and rim on radial and bias-ply tires. Often, the bead can become stuck to the rim after rusting or corrosion occurs, requiring the use of a bead breaker in order to be removed.
A wheel machine is a high-power, high-efficiency blasting operation with recyclable abrasive (typically steel or stainless-steel shot, cut wire, grit, or similarly sized pellets). Specialized wheel blast machines propel plastic abrasive in a cryogenic chamber and is usually used for deflashing plastic and rubber components. The size of the ...
The first hole is dug on one side of the obstacle. This hole must be large enough to fit the tool and allow the operator to aim it. The hole also must be deep enough so that, as the tool compacts the ground, the surface remains undisturbed. The depth of the starting bore pit depends on the type of soil being worked in and how well it compacts.
