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.

Any solid material that is capable of cutting ferrous metals are used, but if the family is the most iron.

Cast iron is less prone to warping than other metals.

This refers not to the machining of cast iron, but the use of cast iron as the bed of the lathe.

Yes, more housing is made ​​of cast iron industrial machines.

Because iron does not tolerate the stress.

Its ability to cause melting and casting, the theme is good.

I assume the question asks why cast-iron is the main material for making the lathe - and in fact most machine-tools.

'

It is easy to machine and gives very good bearing surfaces such as the shears on the lathe bed; thanks to its inherent "self-lubricating" and oil-retaining property due its granular structure of iron crystals interspersed with those of graphite - you soon find the graphite when you machine the stuff!

'

It has a damping effect - it is not as resonant as steel so reduces vibration.

Re-writing the first respondent's last sentence as I think he meant: it melts at a relatively low temperature, and its low viscosity when molten greatly facilitates casting intricate shapes.

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.

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.

Lath martensite and plate martensite are two morphologies of martensite formed during the rapid cooling of austenitic steel. Lath martensite appears as thin, elongated plates or laths and is typically found in low-carbon steels, resulting in a more ductile microstructure. In contrast, plate martensite consists of thicker, broader plates and is generally found in high-carbon steels, leading to higher hardness and brittleness. The differences in their formation and structure influence the mechanical properties of the steel they comprise.

Swiss-style lathes are used for machining components requiring extreme accuracy. some of these lathes are capable of machining to within 0.00025mm or 0.00001in. Swiss-style lathes are used for smaller and/or longer workpieces, the lathes are applicable for different industries to machine parts.

The bed of a NC lathe is at an angle just to ensure swarf slides to the bottom of the machine for collection. They are referred to as "slant-bed lathes". The angle of the bed is dependent to the manufacturer. Some built 90 degree or vertical beds (Monarch Machine Tool Series 220 for example), and others built lathes at varying angles from horizontal, 70, 60 and 45 degrees are the most common, with 45 degrees about the shallowest angle that can be had and still have good chip flow. Other builders use a horizontal base, and use a triangular carriage to achieve the slant effect to shed chips and coolant.
