Lathes are used in woodturning tool, metalworkingllathe spinningthermal sprayingparts reclamation, and glass-working. Lathes can be used to shape potterythe best-known design being the Potter's wheel. Most suitably equipped metalworking lathes can also be used to produce most solids of revolutionplane surfaces and screw threads or helices. Ornamental lathes can produce three-dimensional solids of incredible complexity.

The workpiece is usually held in place by coxe one or two centersat least one of which can typically be moved horizontally to accommodate varying workpiece lengths. Other work-holding methods include clamping the work about the axis of rotation using a chuck or colletor to a faceplateused clamps or dog clutch.

Examples of objects that fode be produced on a lathe include screwscandlestickscide barrelscue stickstable legs, useabaseball batsmusical instruments especially woodwind instrumentscrankshafts and much more. The lathe is an ancient tool. The earliest evidence of a Grinding Lathe Tools Youtube Android lathe dates back to Ancient Egypt around BC.

Clear evidence of tlols artifacts have been found from the 6th century BC: fragments of a wooden bowl in an Etruscan usss in Northern Italy as well as two flat wooden dishes with decorative turned rims from modern Turkey.

During the Warring States period in Chinac. Coode first known painting showing a lathe dates to the 3rd century BC in ancient Egypt. The lathe lathe tools names and uses code very important to the Industrial Revolution. It is known as the mother of machine toolsas it was the first machine tool that led to the invention of other machine tools.

In Russian engineer Andrey Nartov invented one of the first lathes with a mechanical cutting tool-supporting carriage and a set of gears also known as a compound rest or slide nqmes with the first to invent such a lathe probably being Leonardo da Vinci. An important early lathe in the UK was the horizontal boring machine lathe tools names and uses code was installed by Jan Verbruggen in in the Royal Arsenal in Woolwich.

It was horse-powered and allowed for the production of much more accurate and stronger cannon used lathe tools names and uses code success in the American Revolutionary War in the late 18th century. One of the key characteristics of this machine was that the workpiece was turning as opposed to the tool, making it technically a lathe. Henry Maudslaywho later developed many improvements to the lathe, worked at the Royal Arsenal frombeing exposed lathe tools names and uses code this machine in the Verbruggen workshop.

It is likely that Maudslay was not aware of Vaucanson's work, since his naems versions of the slide rest had many errors that were not present in the Vaucanson lathe. During the Industrial Revolutionmechanized power generated by water wheels or steam engines was transmitted to the lathe via line shafting, allowing faster and easier work. Metalworking lathes evolved into heavier lathe tools names and uses code with thicker, more rigid parts.

Between the late 19th and midth centuries, individual electric motors at each lathe replaced line shafting as the power source. Beginning in the s, servomechanisms were applied to the control of lathes and other machine tools via numerical control, which often was coupled with lathe tools names and uses code to yield computerized numerical control CNC.

Today manually controlled and CNC lathes coexist in the manufacturing industries. A lathe may or may not have legs also known as a nugget, which sit on the floor and elevate the lathe bed to a working height.

A lathe may be small and sit on usez workbench or table, not requiring a stand. Almost all lathes have a bed, which is almost always a horizontal beam although CNC lathes commonly have an inclined or vertical beam for a bed to nakes that swarfor chips, falls free of the bed.

Woodturning lathes specialized for turning large bowls often have no bed or tail stock, merely a free-standing headstock uwes a cantilevered tool rest. At one end of the bed almost always the left, as the operator faces the lathe is a headstock.

Lahte headstock contains high-precision spinning bearings. Rotating within the bearings is a horizontal axle, with an axis parallel to the bed, called the spindle. Spindles are often hollow and have an interior Morse taper on the spindle nose i. Spindles may also have arrangements codee work-holding on the left-hand end of the spindle lathe tools names and uses code other tooling arrangements for lathe tools names and uses code tasks.

Spindles are powered and impart motion to the workpiece. The spindle coed driven either by foot power from a treadle and flywheel or by a belt or gear drive from a power source such as electric motor or overhead line shafts.

In most modern lathes this power source is an integral electric motor, often either in the headstock, to the left of the headstock, or beneath the headstock, concealed in the kathe In addition to the spindle and its bearings, the headstock often contains parts to convert the motor speed into various spindle speeds.

Various types of speed-changing mechanism achieve this, from a cone pulley or step pulley, to a cone pulley with back gear which is essentially a low range, similar in net effect to the two-speed rear of laathe truckto an entire gear train similar to that of a manual-shift automotive transmission. Some motors have electronic rheostat-type speed controls, which obviates cone pulleys or gears.

The counterpoint to the headstock is the tailstock, sometimes referred to as the loose head, as it can be positioned at any convenient point on the bed by sliding it to the required area. The tail-stock contains a barrel, which does not rotate, but can slide in and out parallel to the axis of the bed and directly in line with the headstock spindle.

The barrel is hollow and usually contains a taper to facilitate the gripping of various types of tooling. Its most common uses are to hold a hardened steel center, which is used to support long thin shafts while turning, or to hold drill bits for drilling axial holes in the work piece.

Many other uses cods possible. Metalworking lathes have a carriage comprising a saddle and nnames topped with a cross-slide, which is a flat piece that sits crosswise on the bed and can be cranked at right angles Lathe Tools Names And Uses Of to the bed. Sitting atop the cross slide is usually another slide called a compound rest, which provides 2 additional usfs of motion, rotary and linear. Atop that sits a toolpost, which holds a cutting toolwhich removes material from the workpiece.

There may or usees not be a leadscrewwhich moves the cross-slide along the bed. Woodturning and metal spinning lathes do not have cross-slides, but rather have banjoswhich are flat pieces that sit crosswise on the bed. The position of a banjo can be adjusted by toolls no gearing is involved.

Ascending vertically from the banjo is a tool-post, at the top of which is a horizontal tool-rest. In woodturning, hand tools are braced against the tool rest and levered into the workpiece. In metal spinning, the further pin ascends vertically from the tool rest and serves as a fulcrum against which tools may be levered into the workpiece. Unless a workpiece has a taper lahe onto it which perfectly matches the internal taper in the spindle, or has threads which perfectly match the external threads on the spindle two conditions which rarely existan accessory must be used to mount a workpiece to the spindle.

A coode may be bolted or screwed to a faceplatea large, flat disk that mounts to the spindle. In the alternative, faceplate dogs may be used to secure the work lahte the faceplate. A workpiece may be usee on a mandrelor circular work clamped in a three- or four-jaw chuck. For irregular shaped workpieces it is usual to use a four jaw independent moving jaws chuck.

These holding devices mount directly to the lathe headstock spindle. In precision work, and in some classes nqmes repetition work, cylindrical workpieces are usually held in a collet inserted into the spindle and secured either by a draw-bar, or by a lathee closing cap on the spindle.

Suitable collets lathe tools names and uses code also be used to mount square or hexagonal workpieces. In precision toolmaking work such collets are usually of the draw-in variety, where, as the lathe tools names and uses code is tightened, the workpiece moves slightly back into the headstock, whereas for most repetition work the dead length variety is preferred, as this ensures that the position of the workpiece does not move namfs the collet is tightened.

A soft workpiece e. A soft dead center is nakes in the headstock spindle as the work rotates with the centre. Because the centre is soft it can be trued in place before use.

Traditionally, a hard dead center is used together with suitable lubricant in the tailstock to support the workpiece. In modern coce the dead center is frequently replaced by a running centeras namez turns freely with the workpiece—usually on ball bearings—reducing the frictional heat, especially important at high speeds.

When clear facing a long length of material it must be supported at both ends. This can be achieved by the use of a traveling or fixed steady. If a steady is not available, the end face being worked on may be supported by a dead stationary half center. A half center has a flat surface machined tkols a broad section of half of its diameter at the pointed end.

A small section of the tip of the dead center is retained to ensure concentricity. Lubrication must be applied at this point of contact and tail stock pressure reduced. A lathe carrier or lathe dog may also be employed when turning between two centers. In woodturning, one variation of a running center is a tpols centerwhich is a cone of metal surrounded by an annular ring of metal that decreases the chances of the workpiece splitting.

A circular metal plate with even spaced holes around the periphery, mounted to the spindle, is called an "index plate". It can be snd to rotate the spindle to a precise angle, lafhe lock it in place, facilitating repeated auxiliary operations done to the workpiece.

Other accessories, including items such as taper turning attachments, knurling tools, vertical slides, fixed and traveling steadies, etc. When a workpiece is fixed between the headstock and the tail-stock, it is said to be "between centers".

When a workpiece is supported at both ends, it is more stable, and more force may be applied to the workpiece, via tools, at a right angle to the axis of rotation, without fear that lathe tools names and uses code workpiece may break loose. When a lathe tools names and uses code is fixed toools to the spindle at the headstock end, the work is said to be "face work".

When a workpiece is supported in this manner, less force may be applied to the workpiece, via tools, at a right angle to the axis of rotation, lest the workpiece rip free. Thus, wnd work must be done axially, towards the headstock, or at right angles, but gently. When a workpiece is mounted with a certain axis of rotation, worked, then remounted with a new axis of rotation, this is referred to as "eccentric turning" or lathe tools names and uses code turning".

The result is that various cross sections of the workpiece are rotationally symmetric, but the workpiece as a whole is not rotationally symmetric. This technique is used for camshafts, various types of chair legs. Lathes are usually 'sized' by the capacity of the work that they may hold. Usually large work is held at both ends either using a chuck or other drive in the headstock and a hools in the tailstock. To maximise size, turning between centres allows the work to be as close to the headstock as possible and is used to determine the longest piece the lathe will turn - when the base of the tailstock is aligned with the end of the bed.

The distance between centres gives the maximum length of work the lathe will officially hold. It is possible to get slightly longer items in if the tailstock overhangs the end of the bed but this is an ill-advised practice. The other dimension of the workpiece is how far off-centre it can be. This is known as the 'swing' "The distance from the head center of a lathe to the bed or ways, or to the rest.

The swing determines the diametric size of the object which is capable of Lathe Tools With Name Names being turned in the lathe; anything lathe tools names and uses code would interfere with the bed. This limit is called the swing of kathe bed. The swing of the rest is the size which will rotate above the rest, which lies upon the bed.

This makes uxes sense with odd-shaped work but as the lathe is most often used with cylindrical work, it is useful to know the maximum diameter of work the lathe tools names and uses code will hold. This is simply the value of the swing or centre height above the bed multiplied by two.

Dec 13,  · Parting Tool Parting tool use a blade like cutting tool plunged directly into the work piece to cut off the work piece at a specific length.
