Today we will study Definition, Parts, Types, Operation, Specification, advantages, disadvantages, and application [Notes with PDF] of Lathe machine. Lathe Machine and Operations. In geared-Head lathe the gear ratio (Spindle speed to motor speed) is changed by Speed- Lever. Shoulder Turning is used in the case where several diameters are to be turned on the work piece. It only has headstock, tailstock and a very simple tool post. The body of the tailstock is adjustable on the base which is mounted on the guideways of the bed and can be moved. It consists of four jaws and each jaw is independently actuated and adjusted by a key for holding the job. Other lathe accessories include extensions that allow a person to lathe short workpieces, specialty collets, and other items. Hardened and rectified body and shaft, permanently lubricated with special grease. The bed of the lathe machine is the base on which all the other parts of the lathe are mounted. Copyright © 2020 TheMechanicalEngineering.com. Shank $ 44 99. Required fields are marked *. The lathe is one of the oldest manufacturing technologies on Earth. It is the maximum diameter of the workpiece that can we turned on a lathe without hitting the lathe bed. Contour A Lathe works on the principle of rotating the workpiece and a fixed cutting tool. Bench Lathe Small lathe which can mounted on the work bench It is used to make small precision and light jobs. The works, which cannot be conveniently accommodated or machined on a standard lathe, the special purpose lathes are used. It also houses a necessary transmission mechanism with speed changing levers to obtain different speeds.eval(ez_write_tag([[580,400],'themechanicalengineering_com-leader-3','ezslot_6',161,'0','0'])); Accessories mounted on the headstock spindle are: The tailstock is a movable casting located opposite to the headstock on the way of the bed. 4. 5. There are 10 different types of Lathe Machine and those are: Engine Lathe or Center Lathe; Speed Lathe; Turret lathe; Capstan Lathe; Toolroom Lathe; Bench Lathe; Gap bed lathe; Hollow spindle Lathe; Vertical Turret Lathe and; CNC Lathe Machine. This is the simplest form of the lathe and consists of a simple Headstock, tailstock, and a tool post. As the name suggests automatic Lathe machine is a machine in which the complete work and the job handling movements required for the completion of the job are done automatically. Hydraulic seals - Definition, Types, Diagram , Function, Failure, Application. The cutting tool is feed into the workpiece, which rotates about its axis causing the workpiece to be formed to the desired shape. This Machine is also known as the “mother of all machines“. With CNC machining, the computer can control exact positioning and velocity. It is mostly used in the places where production work is required such as in Capstan Lathe or automats.It is used for holding the bars of small sizes (below 63mm). Woodworking has been smooth and accessible to all with the touch of some advanced chucks. Pendulum. The operations performed on Lathe Machine are: Turning is the most common operation performed on the lathe. This design was further improved by the Ancient Romans who added the turning bow and lather the paddle (as there in the sewing machine) was added. The carriage is located between the headstock and tailstock and serves the purpose of supporting, guiding, and feeding the tool against the job during operation. Saves time: Lathe machine because of its extensive high speed and high accuracy saves a lot of time, resulting in the increased production. This video discusses different types of lathe chucks and the not so obvious differences between them. A live center has ball bearings and turns with the workpiece, which allows the worker to use higher speeds without using a lubricant. It supports the tool post and The types of lathe which comes in this category are wheel lathe, gap bed lathe, tracer/duplicate lathe and T-lathe. Drilling operation is a type of machining operation which is used to remove the material from the workpiece by making use of drill bit, which is held stationary in the Tailstock. It is rigidly supported by cross griths. 2019.03.08. There are two basic types of lathe centers: A live and a dead center. The fundamental principle of operation of all lathes is the same and performs the same function, yet they are classified according to the design, type of drive, the arrangement of gears, and purpose. It is mostly used in the chamfering operation. Online Exclusive. Since the entire operation is automatic, these lathes require little attention from the operator. The tailstock is provided to facilitate holding the work between centers and permit the use of tools like drills, taps, etc. It consists of three jaws that move simultaneously by turning a key and the workpiece automatically remains in the center of the chuck opening. cutting tool in its various positions. It consists of the dead centers, the adjusting screws, and the handwheel. In addition to cutting tools, there are many types of lathe accessories, including various centers, extensions, and tool rests.Generally, the type of lathe accessory selected depends on the manufacturer's products and processes. As we know for threading operation requires rotational movement of the job (workpiece) and the linear movement of the tool (tool post). Computer Numeric Control (CNC) is the most advanced form of the lathe machine. "V" and combination beds are used for precision and light duty work, while flat beds are used for heavy duty work. Turret lathe is basically used for repetitive batch production. It is fitted to the lathe spindle with its central threaded portion. The Lathe Machine consists of following Main Parts: I have also shown the different parts in the diagram. It is an H-shaped casting mounted on the top of the lathe ways.
