This tool was designed for a 2G Brown & Sharpe screw machine. A form tool is precision-ground into a pattern that resembles the part to be formed. The form tool can be used as a single operation and therefore eliminate many other operations from the slides (front, rear and/or vertical) and the turret, such as box tools. A form tool turns one or ...
Indexing heads are usually used on the tables of milling machines, but may be used on many other machine tools including drill presses, grinders, and boring machines. Common jobs for a dividing head include machining the flutes of a milling cutter , cutting the teeth of a gear , milling curved slots, or drilling a bolt hole circle around the ...
When a cutting tool such as a drill bit or reamer is used, the feed is done with this leadscrew. The extendible portion of the tailstock is called the barrel, and usually has a Morse taper mount in the end of it to secure the drill or reamer. If the work is heavy, the drill may be further secured from turning with a lathe dog as shown in the photo.
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.
These rigid machine tools remove material from a rotating workpiece via the (typically linear) movements of various cutting tools, such as tool bits and drill bits. Metal lathes can vary greatly, but the most common design is known as the universal lathe or parallel lathe.
A drill chuck is a specialised self-centering, three-jaw chuck, usually with capacity of 0.5 in (13 mm) or less, and rarely greater than 1 in (25 mm), used to hold drill bits or other rotary tools. This type of chuck is used on tools ranging from professional equipment to inexpensive hand and power drills for domestic use.
Push-the-bit tools use pads on the outside of the tool which press against the well bore thereby causing the bit to press on the opposite side causing a direction change. Point-the-bit technologies cause the direction of the bit to change relative to the rest of the tool by bending the main shaft running through it.
Dead center (the conical piece) mounted in the spindle of a lathe and being used to support a workpiece being driven by a carrier setup. A lathe center, often shortened to center, is a tool that has been ground to a point to accurately position a workpiece on an axis. They usually have an included angle of 60°, but in heavy machining ...
