These machines provided by hexagonal turret head instead of the tailstock. It also consists of three tool post.
In these types of lathe machines, multiple tools may be fitted and fed into the work in the proper sequence. The main advantage is that different operations and parts can produce in very less amount of time. And also without changing the tool the quantity and quality are high. Capstan and turret lathe requires more floor space than other lathe machines.
Capstan and turret lathe is using for only large jobs. Read full article on Capstan and Turret lathe. As the name implies these types of lathe machines used for the special purpose and for production work.
In this lathe, special operations are performed such as drilling , grinding , reaming , boring , etc. The wheel lathe is made for finishing the journals and turning the thread on the railroad, automobile cars and locomotive wheels. The gap bed lathe, in which a section of the bed adjacent to the headstock is removable, is used to swing extra large diameter pieces. The axis of the lathe bed is at right angles to the axis of the headstock spindle in the form of a T.
The duplicating lathe machine is one of the duplicating the shape of a flat or round template on to the workpiece. Mechanical, pneumatic, and hydraulic devices are all used to coordinate the movement of the tool to reproduce accurately the shape of the template.
The missile lathe machine which has a very large swing for accommodating long missile component of very large diameter is the most modern and latest in lathe design. In these types of lathe machines, all the work is done automatically. These are the high-speed heavy-duty, production lathes. In these types of lathe machines once the tool is set it performs all the operations automatically to finish the job.
Here the change of tools and feed are automatically. The single operator can control 5 to 6 automatic lathe at a time. Lathe machine performs the different operation such as turning, facing, taper turning, knurling, grooving, parting off, electric turning, thread cutting, reaming etc.
Let it take one by one as follows. Lathe machine operations done either by holding the workpiece between centres or by a chuck are:. Lathe machine operations performed by holding the work by a chuck or a faceplate or an angle plate:. The lathe machine accessories are used either for holding and supporting the workpiece or for holding the tool. The important lathe accessories are. The lathe machine attachments are additional types of equipment used for some special and specific purposes.
The important lathe attachments are. If you like this post please share it with your friends. Enter your email address. Sign Up. Saif M. He completed his engineering studies in and is currently working in a large firm as Mechanical Engineer. He is also an author and editor at www. Notify me of follow-up comments by email. In that case, it will have a cone pulley with back gears in the headstock to provide different speeds to the spindle. It carries a combination of gears, instead of the cone pulley and back gears combination, the lathe is known as geared head lathe and the headstock as all geared head stock.
It is nothing but the same engine lathe but equipped with some extra attachments to make it suitable for a relatively more accurate angle of speeds and feeds. The usual attachments provided on a tool room lathe are taper turning attachment, follower rest, collets, chucks, etc.
This lathe is made to have a comparatively smaller bed length than the usual engine lathe. The most commonly used lengths are to cm. These lathes form as very important and useful group and are vastly used in mass production. These machines are actually of semi-automatic type and a very wide range of operations can be performed on them.
In operating these machines, a very wide range of operations can be performed on them. In operating these machines, a very little skill is required of the operator. Whatever skill is needed of the operator is only in the setting of tools in the turret or capstan head, and once this setting has been successfully accomplished further operation of these machines is more or less automatic.
They carry special mechanisms for indexing of their tool heads. These lathes help a long way in enhancing the quality as well as the quantity of production. They are so designed that all the working and job handling movements of the complete manufacturing process for a job are done automatically. No participation of the operator is required during the operation.
Another variety of this type of lathes includes the semi-automatic lathes, in which the mounting and removal of work is done by operator whereas all the operations are performed by the machine automatically. Automatic lathes are available having single or multi spindles. They fall in the category of heavy duty, high speed lathes mainly employed in mass production.
A large number of lathes are designed to suit a definite class of work and to perform certain specified operations only. The production process of bolts has evolved into an advanced and high-tech multi-step process.
Food safety issues have always been the focus of social concern, and various countries and organizations have also put forward relevant food safety regulations and testing standards to ensure the health and safety of food processing and food processing technology engaged with it.
Selective laser sintering is an additive manufacturing technology that sinters small particles of polymer powder into a 3D three-dimensional structure through high-power laser light; thus, this is also called selective laser sintering 3D printing, or SLS 3D printing. Etching is a technique to process the surface of the object by using chemical strong acid corrosion, mechanical polishing, or electrochemical electrolysis.
In addition to enhancing aesthetics, it furthermore increases the added value of the object. From traditional metal processing to high-tech semiconductor manufacturing are all within the scope of applications of etching technique.
What Is About Welding? Welding is a technique and process for joining metals or other thermoplastics by heating or pressing. Metal Welding Arc Welding Global. What Is a Data Processing Center? Central data processing services are usually used to complete key tasks in computer and telematics processing; generally, include environmental control air conditioning system to prevent fire, etc. What is Automated Guided Vehicle? During the operation of the factory, the flow of materials determines the production efficiency of the factory.
Recently, automation equipment has gradually become a production line system, but the supply or handling of materials still relies on manual handling operations by personnel, resulting in often unsmooth logistics and production flow.
Or there is an interruption, and the production line does not want to occupy a huge space, so Automated Guided Vehicle AGV technology responds to it to achieve unmanned handling. What Is a Smart Machine Tool? However, the ideal features of the tool room lathe include, taper turning, follower rest, collets, chucks, etc. Comparatively, this lathe has a smaller bed length than the engine lathe as the most used length is to cm. They are actually semi-automatic type and various operations can be performed on them.
Little skill is required to operate the machine, only skills required is in the tools setting in the turret or capstan head. Once this setting is successfully done, the operations are done automatically.
Automatic lathe is known for their enhancement in quality and the quantity of production. This machine is so perfect that the complete manufacturing process is automatically achieved. This means, no participation of the operator is required during the operation.
And just as the semi-automatic lathes, the work of operators is just the mounting and removing of workpiece from the spindles. Well, automatic types of lathe machine are available with a single or multi spindles.
They are classified as heavy duty, high speed lathes mainly used for mass production. Some lathe is purposely designed for specific project or to suit a definite class of work. They are more efficient and effective in what they do. These machines are classified as the following;. Precision lathe — these machine tools are capable of a dimensional accuracy as small as 0.
It previously rough-turned work piece in many cases, replace a high class grinding machine due to its fine dimensional accuracy. Facing lathe — in facing lathe, the carriage is driven by a separate motor, while the main spindle is independent. Tailstock is not indicated in this machine. It is used to machine the end faces of bulky cylindrical projects.
Frontal lathe — these types of machine tools contains two carriages, one on each end. Two tool head are also provided, which allows machining of two jobs simultaneously. It is suitably use in machining smaller jobs. Vertical lathe — this special lathe carries a vertical column, which the cross slide and vertical slide are fitted to it. It is used for boring and turning very large and heavy rotating parts like flywheel and large gear blanks.
Crankshaft lathe — the crankshaft lathe carries all feature like other common lathes like taper turning, threading etc.
