Many people know Lathe machine and saw in there laboratory or company but not aware much about parts of lathe machine and lathe machine diagram . So here we will explain what it is, how to use and their parts.
A lathe machine is used to design or shape a metal piece accurately. The removal of material from metal is called Machining.
Parts of lathe machine
The headstock is fixed on the machine and it consists of many pulleys, lever, spindle, chuck, and gear box.
The spindle is in the head box which rotates a shaft which is connected to the chuck. This chuck holds a work piece, so the work pieces also rotate.
The gear box is in the head stock which rotates the chuck at different speeds.
Chuck is used for mounting of metal pieces which are not round shape while having a triangular or square shape.
The tailstock is a moveable part and could be locked. It consists of a barrel that can move forward and backward. Barrel consists of a Dead Centre which is used to support a work piece.
The carriage is also a movable part which moves on bed ways. It moves on left and right. It consists of the saddle, cross slide, compound rest, top slide or tool post and the apron. It is used as mounting and for the position of tool post.
The saddle has H shaped. It is on the carriage which helps cross slide to move back and forth on the machine.
Cross slide is on the carriage and moves on the saddle. It moves back and forth to give depth of cut to the metal specimen by using hand wheel.
Compound slide is on the cross slide which can rotate. It gives support to tool post. It is used in
taper turning by giving an angle.
Tool post is on the compound rest and used to clamp the cutting tool.
The apron is on the front of the saddle which has hand wheel and levers. It is used to control the movement of
carriage on the bed.
The bed is the main part of the machine which is fixed. It gives support to all parts of machine like Head stock, Tail stock, Carriage etc.
Way is machined on bed which is actually the rail and provide the movement to tailstock and carriage.
It is a long threaded rod on the bed which provides an automatic feed to carriage from head stock to tail stock. It is used for giving threads to the work piece.
