Types of Lathe Machine and intro

Intro:-

A machine for shaping a piece of material, such as wood or metal, by rotating it rapidly along its axiswhile pressing a fixed cutting or abrading tool against it.

Types:-

Center lathe / engine lathe / bench lathe.
Turret lathe and capstan lathe.
Multispindle lathe.
CNC lathe / CNC turning center.

Center lathe :-

A lathe centre, often shortened to centre, is a tool that has been ground to a point to accurately position a workpiece on an axis. They usually have an included angle of 60°, but in heavy machining situations an angle of 75° is used.

Cpstan lathe:-

A lathe with a revolving tool holder that enables several tools to be permanently mounted on it.

Multispindle lathe:-

Multi Spindle Automatic Lathe can provide the various types of machining such as boring, turning, chamfering, threading, grooving, and drilling by moving the workpieces between 6 or 8 stations(machining position). This machine tool enables to realize overwhelmingly fast cycle time by dividing into 6 or 8 processes. Generally Multi Spindle Automatic Lathe can provide approx. 4－5 times of machining speed comparing to the Single Spindle NC Lathe although the speed can be widely varied depending on the various conditions

CNC lathe:-

Speaking of 6 Spindle Automatic Lathe, 1 spindle is used for loading and un-loading, and other 5 spindles are used for machining. SHIMADA’s 6 Spindle Automatic Lathe can attach 3 NC slides and 8 Spindle Automatic Lathe can attach 1 NC slide. The rough machining is provided at non-CNC slide positions and proceeds the finishing at NC position, therefore both high-speed and high-accurate can be possible with this machine.
