All You Need To Know About Metal Lathe

A metal lathe or metalworking lathe is a large class of lathes designed for precisely machining relatively hard materials. These rigid machine tools remove material from a rotating workpiece via the (typically linear) movements of various cutting tools, such as tool bits and drill bits.

With the advent of technology, these lathe machines have also been modernized. They can now be controlled by a computer to perform the desired operation; these are termed CNC Lathe (Computer Numerical Control))

Metal Lathe – Gears

The primary component of a lathe is the cast iron bed. All the other components of the machine sit on this element. The component which holds the workspace is termed as a Chuck. This is fastened on the spindle which rotates the chuck thereby rotating the workpiece.

The other major element of a lathe is headstock which is positioned at the left side of the bed. This cast iron component is the gripping device for gear chain, spindle, the driving pulley and so on.

Another component that is placed on the right of the bed is tailstock. This is purposed for work support when needed. Boring the metal piece can be done using this component.

With so many uses for this machine one can find numerous dealers for new and used metal Lathe on the market.

What to look for in a Metal Lathe?

When buying a used metal lathe machine whether used or a new one, look for these details:

GO for the biggest lathe in your budget.

When buying a used lathe check for the bed near to the chuck, this is the prime component that wears easily. If it is worn the repair cost is expensive so better don’t go for such lathes.

Get a gear driven head when you can manage cost. The belted ones are difficult to handle rpm changes.

For a novice worker, belted ones could be a blessing. If the machine slows down due to an improper handling the belt only slips without causing much damage to the costly equipment.

Do a proper research before you zero on a lathe. Don’t just look at the budgetary aspects but also the purpose of the machine. Is it being used for home projects or any small scale industry?

Lathe – Maintenance

These highly accurate machine components operate round the clock with proper maintenance. Operating a lathe requires a professional for better performance. There is always a chance of excessive wear if the lubrication is not done properly or the nuts and bolts are loosened. This may lead to some dangerous situations.

Make sure that the precision surface of the machine is clean from dirt. Proper checking of the parts before operating the machine is highly recommended.

Manufacturer’s instructions are to be followed strictly before attempting any lift operation. Proper lubrication safeguards the metal components of the machine thereby increasing the longevity of the machine.

Everything You Need To Know About Used Lathes

A lathe is a compilation of tools which are capable of mechanically machining pieces through the revolution. Its work is simple: It rotates the piece in question, holding it in the head of the machine or fixing it in the centering points, while other cutting tools are advancing constantly on the surface, cutting the material and leaving the chip after itself, according to the patterns to follow for the development of machining of the piece to be made.

Development of the lathe for metal in the current industry:

A lathe is an essential machine for all types of industrial machining processes. The tool that produces the cut goes on a car or rails that move parallel to the Z axis. Another car, which moves along another axis, called the X-axis, is the one that moves in the radial direction with respect to the turned part. In some models, there is also a supplementary axis, which can be tilted to make cones and other more complex shapes. In the movement of the main carriage, along with the axis of rotation, the work called as displacement is performed, while in the movement of the transversal carriage, perpendicular to the axis of symmetry, the facing is produced.

Different types of lathes for metal and their applications:

The simplest lathes are the famous parallel lathes. These have a third auxiliary car, whose mechanism is manual at the same time as rotating or tilting. This car is called as a chariot, on which the tool-holder tower is attached, while the chariot is coupled to the transversal car, thus being able to develop conical shapes.

Different types of control:

Parallel lathes are part of the category of conventional lathes. Other types of lathes with respect to the type of control are the automatic lathes by numerical control, more known like CNC lathes and the lathes of fixed cycles that represent the economic version of the CNC. Several types of lathes can have one of these types of control.

Types of particular lathes:

Among the various types of lathes stand out the automatic lathes with the feeding of bars, which allow automated machining thanks to the storage of bars and a system for feeding them. There are also revolver lathes and several types of vertical lathes. Heavy vertical lathes are designed to machine large pieces, which are fixed to the plate or by other systems because their clamping is much more complicated to perform. The revolving lathes reduce the working time considerably since it allows the simultaneous work of several different tools.

Buy used lathes:

The sale of second-hand lathes is a process through which companies and small workshops can supply their machinery needs taking advantage of offers. There are many companies have used lathes for sale. The prices that these used lathes reach in the purchase process allow that the acquisition of these machines can be done without having to invest a large amount of money in their purchase, taking into account the market price that is handled by first-hand machines.

The advantages of buying used lathes:

Used lathes for sale by means of the acquisition of a pre-owned lathe, with a cheap price, the needs of machinery for different production processes can be met. For example, buying a second-hand used lathe with CNC technology is a good formula to obtain machinery to increase the production capacity and the precision of finishing when carrying out serial work and machining of complex parts. A lathe for second-hand metal will offer the necessary benefits for a good machining of metals.

Infographic: Tips To Choose The Right CNC Machinery!

CNC machining (Computer Numerical Control) is a process used in the manufacturing sector that involves the use of computers to control machine tools. Some tools that can be controlled in this manner include lathes, mills, routers and grinders. So, if your business involves these processes, you must be looking out for CNC machines.

But finding a used model can be a more smarter and economical choice. But how exactly do you choose one? Here are some tips. Always research the ins and outs of the machine you are thinking of buying. Research the availability and replacements of the parts of the machine in case some parts stop working. Ask for the documents of the machine. Try to get hold of as much documents as you can. You don’t want your machine to crash within days after buying. To avoid this fate, buy the machine from a reputable source only.
