A watchmaker using a lathe to prepare a component cut from copper for a watch. A lathe is a tool that rotates the workpiece about an axis of rotation to perform various operations such as cutting, sanding, knurling, drilling, or deformation, facing, turning, with tools that are applied to the workpiece to create an object with symmetry about that axis. Lathes are used in woodturning, metalworking, metal spinning, thermal spraying, parts reclamation, and glass working. Lathes can be used to shape pottery, the best known design being the potters wheel. Most suitably equipped metalworking lathes can also be used to produce most solids of revolution, plane surfaces and screw threads or helices. Ornamental lathes can produce three dimensional solids of incredible complexity. The workpiece is usually held in place by either one or two centers, at 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 collet, or to a faceplate, using clamps or dogs. Examples of objects that can be produced on a lathe include candlestick holders, gun barrels, cue sticks, table legs, bowls, baseball bats, musical instruments especially woodwind instruments, crankshafts, and camshafts. Historyedit. Craftsman Gregorio Vara working a chair leg on a lathe in Tenancingo, State of Mexico. The lathe is an ancient tool, dating at least to ancient Egypt and known to be used in Assyria and ancient Greece. The lathe was very important to the Industrial Revolution. It is known as the mother of machine tools, as it was the first machine tool that lead to the invention of other machine tools. The origin of turning dates to around 1. BCE when the Ancient Egyptians first developed a two person lathe. One person would turn the wood work piece with a rope while the other used a sharp tool to cut shapes in the wood. Ancient Rome improved the Egyptian design with the addition of a turning bow. In the Middle Ages a pedal replaced hand operated turning, allowing a single person to rotate the piece while working with both hands. The pedal was usually connected to a pole, often a straight grained sapling. The system today is called the spring pole lathe. Spring pole lathes were in common use into the early 2. Exact drawing made with camera obscura of horizontal boring machine by Jan Verbruggen in Woolwich Royal Brass Foundry approx 1. An important early lathe in the UK was the horizontal boring machine that was installed in 1. Royal Arsenal in Woolwich. It was horse powered and allowed for the production of much more accurate and stronger cannon used with success in the American Revolutionary War in the late 1. One of the key characteristics of this machine was that the workpiece was turning as opposed to the tool, making it technically a lathe see attached drawing. Henry Maudslay who later developed many improvements to the lathe worked at the Royal Arsenal from 1. Verbruggen workshop. During the Industrial Revolution, mechanized 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 machines with thicker, more rigid parts. Between the late 1. Beginning in the 1. CNC. Today manually controlled and CNC lathes coexist in the manufacturing industries. DescriptioneditA lathe may or may not have legs, which sit on the floor and elevate the lathe bed to a working height. A lathe may be small and sit on a 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 ensure that swarf, or 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 and a cantilevered tool rest. At one end of the bed almost always the left, as the operator faces the lathe is a headstock. The 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 exterior threads andor an interior Morse taper on the inboard i. Spindles may also have exterior threads andor an interior taper at their outboard i. Spindles are powered and impart motion to the workpiece. The spindle is driven either by foot power from a treadle and flywheel or by a belt or gear drive to a power source. 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 stand. 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 a truck, to an entire gear train similar to that of a manual shift auto 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 are possible. Metalworking lathes have a carriage comprising a saddle and apron topped with a cross slide, which is a flat piece that sits crosswise on the bed and can be cranked at right angles to the bed. Sitting atop the cross slide is usually another slide called a compound rest, which provides 2 additional axes of motion, rotary and linear. Atop that sits a toolpost, which holds a cutting tool, which removes material from the workpiece. There may or may not be a leadscrew, which moves the cross slide along the bed. Woodturning and metal spinning lathes do not have cross slides, but rather have banjos, which are flat pieces that sit crosswise on the bed. The position of a banjo can be adjusted by hand 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. AccessorieseditUnless a workpiece has a taper machined 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 exist, an accessory must be used to mount a workpiece to the spindle. A workpiece may be bolted or screwed to a faceplate, a large, flat disk that mounts to the spindle. In the alternative, faceplate dogs may be used to secure the work to the faceplate. A workpiece may be mounted on a mandrel, or 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. Sears Roto Spader tillerHi all 1. June 2. 00. 7If any of you are running a B S engine on your tillers, then you can use the engine info as an indicator for the age of your unit. Write down your engine info Model, Type, and Code and go to the B S website. It will tell you how to read the code info and find the date of the engine, which should narrow down the age of your tiller. Visual Foxpro Serial Communication Protocol on this page. You can also download an IPL Illustrated Parts List from the B S site, which will provide you with a schematic of your engine. Just make sure to read the notes in the IPL as the part numbers are different for certain Type numbers. Also, when ordering engine parts be sure to discuss it with your B S supplier as some of those numbers will be outdated, but the supplier should have a handy little program that will help him to find the most current part number. I was able to get new parts for my 7. B S supplier here.
