Without knowing what the question is, I provided a couple of sites that might help:
The headstock of a centre lathe can be opened, revealing an arrangement of gears. These gears are sometimes replaced to alter the speed of rotation of the chuck. The lathe must be switched off before opening, although the motor should automatically cut off if the door is opened while the machine is running (a safety feature).
The speed of rotation of the chuck is usually set by using the gear levers. These are usually on top of the headstock or along the front and allow for a wide range of speeds.
However, sometimes the only way to set the lathe to a particular speed is to change the gear arrangement inside the headstock. Most machines will have a number of alterative gear wheels for this purpose.
* http://www.technologystudent.com/equip1/mlathe1.htmThere are many variants of lathes within the metalworking field. Some variations are not all that obvious, and others are more a niche area. For example, a centering lathe is a dual head machine where the work remains fixed and the heads move towards the workpiece and machine a center drill hole into each end. The resulting workpiece may then be used "between centers" in another operation. The usage of the term metal lathe may also be considered somewhat outdated these days, plastics and other composite materials are in wide use and with appropriate modifications, the same principles and techniques may be applied to their machining as that used for metal.

What does changing the gears on the center lathe do?
Changing the gears on a lathe enables it to cut certain pitches of threads.
How many gears to a lathe machine?
It depends on the brand. A lathe could be supplied with anything from two to seven separate interchangeable gears for thread cutting purposes. If you are asking how many gears a single standard center lathe has in total, the number could exceed fifty.
Where are Rack and pinion gears used?
automobile steering, lathe etc
What is back gear attachment in lathe?
The back gears on a lathe can be changed to enable it to cut an even wider variety of thread pitches.
How does a center lathe work?
It doesn't.
What is the use of back gear arrangement in a lathe headstock?
The back gears on a lathe can be changed to enable it to cut an even wider variety of thread pitches.
Use of center lathe for Friction welding?
Centre lathe can use for friction welding.
What is the size of a lathe that measures 6in from the center of the spindle to the main bed?
A lathe that measures 6 inches from the center of the spindle to the closest part of the bed is considered a lathe with a 12 inch swing.
What is function Spindles in the lathe?
function spindles in the lathe There is a long time to find a center cutting machine parts and maintenance.
Where is the rotor point at top dead center?
Iti Lathe
What are the accessories used for on the center lathe?
Accessories used on a center lathe are:3 and 4 Jaw chuck - Clamping the workpieceChuck spanner - For tightening the workpiece in the chuckSteady - Stabilizing a long workpieceTraveling steady - Stabilizing a workpiece close to the cutting areaCenter, dead center, pipe or rolling center - Centralizes and stabilizes the end of the workpiece from the tail stockCutting tools - Used for cutting or machining the workpieceWrench set (Supplied with the machine) - For setting the gears at the rear of the headstock for specialized operations and machine maintenanceManual oil pump - For lubrication of the machine
What is the use of the tail stock sleeve in centre lathe machine?
Tails tock sleeves are used on CNC lathes. It is the equivalent to a tail stock quill on a center lathe but in this case it uses hydraulic pressure to move it in and out of the tail stock. The function of both tail stock sleeve or quill is to clamp the workpiece by means of a center that is inserted into the sleeve or quill. On a center lathe it is used for drilling also but not on a CNC lathe.
