The lathe is the standard metalworking machine used today to produce rotationally symmetric metal workpiece though precise, cutting production processes. There is a wide range of rotational components that can be produced on a lathe machine. This includes components from simple, cylindrical shafts, circular and spherical formed components, to complex structures like gear theeth. Additional devices are required on a lathe when producing uneven forms. Today, universal metal lathes allow for the maximum turning of a workpiece.
On a lathe, the workpiece is clamped in between the lathe spindle and the tailstock. There are advantageous pre-products that already have an approximated level of roundness. Angular or irregularly formed products, like special profiles, tend to have imbalances. These imbalances can lead to imprecise processing or damages to the metal lathe machine. Ideal pre-products that are processed on metal lathes include continuously cast round bars made out of solid material, or round pipes with thick walls. Long workpieces are additionally held up via supports. Once the workpiece is clamped in and spun into rotation, it is guided to the cutting tool via a tool carriage. The chippings are continuously removed by its adjustable feed. The carriage can traversely or longitudinally move towards the rotional axis of the workpiece.
The basic requirement of a metal turning lathe is that it needs to stand solidly. This is why it has a cast iron frame. Large lathes and lathe centers need an additional cement foundation. This absorbs the natural oscillations of the machine lathe as well as external vibrations that occur in close promiximity to the machine. The precision of turned components that are produced within a hundreth of a milimeter is directly impacted by these distributing vibrations. An electric motor and a gear box are used to power the lathe's spindle. The rotation speed and the turning of the spindle needs to be adjustable. The more of the lathe's parameters that can be adjusted, the more comprehensive the processing of a component can be. Spindles, supports, carriages and tailstocks are integrated into a monolithic grey cast iron cover. This needs to be particularly good quality, massive and precisely constructed. The disadvantage of a cast component is that it cannot be welded. Bangs, cracks or other damages to the body usually means that the whole machine has to be thrown away. Therefore, metal lathes should be installed in a certain place and then not moved again. Useful accessories for a machine lathe include lighting and an extraction system. Lathes metal also contain CNC control and a cover. Instead of a tailstock, large high-end lathes have two powered spindles. Complete lathe machining centres also having a tool changer. The most common tasks undertaken on a lathe are straight turning, face turning, drilling, reboring and the production of internal and external threads.
Depending on the turning axis, lathes are available either in a vertical or horizontal construction. Vertical lathes are used for processing components with a large cross section; the components are vertically clamped in and turned. They are usually available without an additional chuck. One of the most common types is the horizontal lathe. These are generally called universal lathes. The universal lathe is usually used for training purposes. There is an enormous range of metal lathe machines for sale, available in all sizes. The small metal lathes are used for DIY purposes or by watchmakers. The largest lathes can take up an entire industrial hall. The most commonly used lathes are the mid-sized universal lathes, CNC lathes and automatic lathes.
Workers who want to operate a lathe require a certain level of qualification before they can be authorised to do so. Beginner courses cost over 1,000 Euros at vocational training institutes. This is the recommended basic requirement for freely operating a lathe center. Ideally, lathes are operated by trained cutting machine operators. In addition to training, a high level of experience is also required. Therefore, trained turners (like welding machines) can constantly increase their qualifications with additional certificates. Laymen and unskilled workers would not be able to usefully help during the operation of a lathe machine. The most they could do is clean the lathes (if they are off) and turn the lathes back on. However, the worker needs to be briefed on the lathe's risks and safety measures.
Lathes have a conveyor belt, upon which the workpiece is placed. These conveyor belts are designed in such a way so that the workpiece arrives at the turning station in a specific position. The turning process is then done automatically. Afterwards, the workpiece is guided out and taken from the machine. The loading and unloading process can be undertaken automatically by an industrial robot. If turning is done automatically, it is important to have continuous quality control. The general wearing out of tools can be identified through regular and thorough checks. This prevents the production of waste and the risk of complaints. Just like all cutting machines, lathes have the need to be regularly cleaned. Cooling lubricants and chippings are very adhesive and can form hard crusts. It is necessary to clean the lathe daily and conscientiously.
Lathes are machine tools on which operations such as turning, drilling, cutting and sanding can be performed on a rotating workpiece. There are many different kinds of lathe machines available. Here is a selection of those most commonly found on used industrial machinery auction sites. A good example for a type of lathe is the BAILEIGH bench lathe, here is also the specification of this type of machine for you to get a general idea.

Lathes are extremely versatile, precision machine tools on which various actions can be carried out, so they are very much in demand in a multitude of manufacturing industries and businesses. Due to this usefulness and popularity used metal lathes for sale are very much sought after. However, if you look for second hand lathes for sale online you are more than likely to find what you need, due to the wide selection of used industrial equipment auctions that have developed in recent years. It's a fact that, though, this important piece of equipment can prove to be expensive, especially when it comes to CNC lathes. Fortunately, there is a solution to this problem in the form of used metal lathes, which are often easy to obtain at significantly lower prices than their brand new counterparts. Additionally, if you see a used lathe for sale you know that the chances are it's been well taken care of, has been built to be durable and robust and will prove to be dependable. If you are looking for a used metal turning lathe for sale then you will find low prices, a wide selection of all types of lathes and complete convenience at used industrial machinery auctions, the number one source for this kind of equipment.
As we know a lathe is a machine that is used to produce precise parts. These components are generally produced as mechanical components for other machines stress on a lathe machine will impact the precision to which it can process workpieces. The storage areas and guideways start to give way and the static components can lose their angularity. This is usually not caused by age, but the way and regularity in which the lathe is used. This impacts their dimensional accuracy. Therefore, it is recommended to produce a test component on a used metal lathe for sale in order to see clearly what the machine's operational capability is. Used lathes can be easily bought at a bargain price at second hand market. There are numerous service providers that can repair used lathes for sale for a good price in case if a second hand lathe is broken. Buying a used lathe always requires expertise and it is important to undertake a thorough examination of the used lathe before buying. Several used lathes for sale can be found on the TradeMachines.com used industrial machinery market which are aggregated from our partner auction houses and markets. You can buy a used metal lathe on the portal of individual auction houses to which you will be taken from our website in just one click.
Regarding lathes, it is better to buy a good-quality used machine than a bad-quality new machine. In recent times, there have been numerous suppliers of lathe machines from countries where there is no quality certifications. These machines can undertake the require tasks, but if they are particularly cheap, they usually have a very restricted working life. Machines made by German or European manufacturers can be a decade old, and still perform well in the long run. Recommended manufacturers of lathes are HEYLIGENSTAEDT, HARBOR FREIGHT, GILDEMEISTER, DÖRRIES, GRIZZLY, WALDRICH, WEILER and MEUSER.
