Lathe- lathe is machine in which the cutting tool perform various motion against the metal job. To form various shape & size of jobs. lathe is generally a machine in which different cutting tools are there.There is generally Single cutting tool & multiple cutting tool. lathe contains various components. Various required shapes & sizes of metal jobs are formed. The spindle rotates with high speed & the metal job is attached with the chuck.
Components of lathe
BED- it is base or Foundation which is made of single casting. It is very heavy part of lathe & used as a base for lathe.
HEAD STOCK- The head stock is on the left side of lathe bolted with bed. It contains chuck, spindle, driven, gears etc.head stock is generally a part of lathe which is attached with the base or Foundation.
Tail Stock- it is the component of lathe which is on the right side of lathe. And the tail stock is free to move. It can be easily move & used for driller holding.
Carriage- it is component of lathe used for supporting & tool control.
Carriage contain various parts various parts which are shown below.
Saddle- it is part of carriage and is used for supporting cutting tool & moves along with the guide way.it is and H-casting type form component of lathe & is just about the bed and can be slide easily.Used for supporting & tool control. It moves along with guide ways.
Cross-slide- it is the tool post used for supporting & holding.
Compound rest- it is part of the carriage & used to machining of metal job at various angles. Taper turning is generally a cutting the metal job with an angle.
Apron- it is generally fitted with saddle. It has gear, lever& clutches attached for moving carriage as lead screw are attached
For (used in thread cutting operation)
Lathe accessories- it is used for supporting & handling purpose.
Chucks- three jaw universal chuck
Four Jaw independent chuck
Types of lathe
Speed lathe- it is a type of lathe in which the spindle rotates at high speed & variable motor is attached to the head stock of the lathe. In speed lathe the spindle rotation is at very high rpm & used for machining in various purposes like in machining of wood, polishing etc
Engine lathe- it is a center lathe & it provide required amount of spindle speed. The speed of spindle is not more as it can be set at the required amount.used for forming various shape& sizes of metal jobs.in this the carriage performs longitudinal direction & transverse direction.
Bench lathe- it is a type of lathe which is mounted on the bench. It's size is small than speed lathe & generally used for obtaining more accuracy & used for less sizes of metal jobs making with good accuracy.
Tool room lathe machine- it is a type of lathe which produces number of metal jobs with high accuracy & is more accurate then the engine lathe.tool room lathe are lathe which produces jobs with accurate.
Turret lathe- it is a type of lathe which perform motion by using multi cutting tool.
This type of lathe are generally used for obtaining jobs in bulk or used in mass production.
Automatic lathe- this is a type of lathe in which the tool rotates automatically for forming various sizing & shapes of metallic jobs. As the name suggests it performs automatic functions & produces number of jobs in mass production.
