It will be often desirable to know the power which is being consumed in operating a lathe on certain work for which data is required. For most purposes this can be sufficiently approximated by calculating the power of the lathe from the width of the belt and its speed in feet per minute.

For such purposes it is usual among mechanical engineers to consider that a one-inch belt traveling a thousand feet per minute will transmit one horse-power. This will give us a key to the entire calculation.

Knurling is a machining process normally carried our on a centre lathe. The act of Knurling creates a raised criss cross pattern on a smooth round bar that could be used as a handle, or something that requires extra grip

Parallel strips, which are hardened and ground steel pieces sold in matching pairs, are used in a vice or bolted to the machine table to support and accurately set jobs. Their purpose is to provide clearance so drilling and tapping operations can be done without cutting into the machine table.

An operation performed on a lathe that feeds a tool at an angle to the length of the workpiece in order to create a conical shape.

The package is part of the workpiece.

Jacques de Vaucanson built the first all-metal lathe around 1751, according to Book Rags. Henry Maudslay, who is considered the "father of the industrial lathe," invented the first screw-cutting engine lathe in 1797.

The main operation in a lathe machine is to turn material. In all lathes, a piece is held and rotated around an axis while metal is cut.

It is the radial distance from spindle center to bed guide ways so that it can be turned with out fouling bed and it is termed as swing over bed. If it is a gap bed machine then another swing specification termed as swing over gap. Another swing specification is swing over cross slide. This specification become important while machining a job in between centers.

Obviously it would depend on the stainless grade because stainless is an alloy, so the speed rate would differ slightly depending on your grade.

The most important factor would be the type of cutter you use, if you are using Carbide cutting tools, with sufficient coolant you can run it at about 90-110 m/p/m (90 to 100 meters per minute)

If you using high speed steel cutters run it no more than about 30m/p/m.

My best advice to you is to ask for the manufactures recommendations they will give you a limit to work in, always start between lowest and middle of manufactures speed recomendations and then work your way up in speed if necessary. If your speed is correct you get a better finish and longer toolife.

Remember that if you run tools at higher speeds you decrease their life, the time taken to cut the material is determined by the feed-rate and not the speed, even on a lathe which has feed set to federate per revolution will only differ slightly.

Hope this helps…

it is an old machine.It can be ised for various operations like turning,taper turning,knurling,slotting,facing,threading etc. But it can be used mostly only for cylindrical jobs. you can find it in many small workshops.

They are essentially the same machine. Capstan is British usage, Turret, US. One old and still technically correct usage of Capstan was the (Turnstile winch) were Bars were extended and seamen walked round and round to weigh the anchor. Almost certainly this inspired the lathe term, as this is a maritime country (UK). The Wheel or circular component on a capstan lathe, however is usually three spoked and Vertical and drives the ram ( containing the usually hexagonal turret- 6 tools) back and forth into the work. They are or were very popular in the automotive sector for fabricating standard parts.

In order to increace the efficincy of a machine, you must eliminate losses of

energy between the input and the output. This almost always means reducing

or eliminating friction, either within the guts of the machine, or between the

machine's moving parts and the outside world. That's the reason that greases,

oil, other lubricants, and streamlining are so popular.

There are numerous parts on a lathe, all of which have a specific purpose. The headstock is responsible for rotating whatever you are working on. The ways are guide rails that ensure any movement is accurate.

make recuritment plan from previous expereinces. Ask your seniors to assist you.

The bed length of a lathe is the total length of the bed way from where it starts to (close to the headstock) to where it ends.

When a lathe is advertized for sale it would show for example: 200mm x 1000mm or 8" x 40". The 200mm or 8" describes the "swing" of the machine and the 1000mm or 40" describes the workable distance between the chuck and center. This should not be confused with the bed size of a lathe as the bed houses the tail stock and therefore the distance is shortened.

Low carbon content <0.6% results in lath structure as opposed to plate or needle structure for high carbon content >0.6%

The spindle of a lathe is a rotating hollow tube within, and protruding the head stock and to which a chuck, drive plate or facing plate attaches and rotates to enable machining.

It is housed within the head stock in bearings and has some gears around it which is driven by other gears which in turn is driven by an electrical motor.

dont know :P

A lathe is not a lever.

A chuck is a rotating clamp for holding a workpiece to your headstock spindle. If you've got one, you can turn the outside of a bowl to shape (as long as you turn some sort of a foot on the bowl), then flip the bowl around, clamp the foot in the chuck and turn the inside. This lets you get really creative with the foot.

There are jaw chucks (which have jaws, just like it sounds) and vacuum chucks, which look like a little cup--you attach a vacuum pump to your lathe, put the workpiece in the cup, draw vacuum and turn away.

In the 1800s, a lathing hammer was primarily used in the construction of wooden structures, particularly for fastening lath to wooden frames before plastering. The hammer typically featured a flat striking surface on one side for driving nails and a pointed end or claw on the other for removing nails or prying wood. Craftsmen relied on this tool for its efficiency in preparing walls for plaster, contributing to the overall strength and finish of buildings. Its design allowed for precision work in the intricate carpentry of the time.
