Metal spinning, thermal spraying, woodturning and metalworking are the common operations performed with a lathe machine. Bench lathe. The work is turned straight when it is made to rotate about the lathe axis and the tool is fed parallel to the lathe axis. Engine or Center lathe: 7. well, there is supports for the shafts. It only has headstock, tailstock and a very simple tool post. The four main types of lathes are * Speed Lathes * Engine Lathes * Tool Room Lathes and * Turret Lathes So let’s start . Lathe Machine. There are various cutting tools used in a lathe machine to perform multiple operations. A lathe is a machine that rotates the piece on the axis in order to perform various operations like cutting, facing, knurling, deformation and more. Some variations are not all that obvious, and others are more a niche area. Most can use a variety of jaw sizes. In this post, we will understand a lathe machine’s working principle, its types, and features, and the operations we can perform on it. Various types of lathe machine are available. They’re also used for metal working, metal spinning, glass working, and … 6. Today we will study Definition, Parts, Types, Operation, Specification, advantages, disadvantages, and application [Notes with PDF] of Lathe machine.. Very flexible System. Lathe or CNC lathe is a machine usually used to produce turned parts, shaping different materials into desired shapes. Types of lathe machine Lathe machines are classified according to their construction and design. Initially the basic operation was to cut cylindrical metal stock which was then further developed to produce screw threads, tapered work, drilled holes, knurled surfaces and crank shafts. Lathe is one of the most important machine tools in the metal working industry. As we all know, to perform a particular operation in any machine we need to use some attachments, mandrels and rests are one of them. 1. Some of them are: 1. lathe machine description: the lathe machine is classified into 16 types according to the control method, the machine structure, the purpose of the machine, and the processed materials, also classified by basic type of machined parts Production lathe – in this lathe machine types, the bed is made to be inclined towards the rear. Types of metal lathes. bar turret lathe, chucking turret lathe, vertical lathe etc. Lathe Machine is one of the oldest machine tools in the production machine.This Machine is also known as the “mother of all machines“. Lathe Machine Diagram : Types of lathes : 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. feed selector. • Determine the RPM for different materials and diameters.
