The apron on a lathe is suspended from the saddle. It houses a gearbox connecting the carriage hand wheel to the rack enabling longitudinal movement of the saddle. It also houses the half nut and its lever for thread cutting and power feed levers.

What is difference between turning machine and lathe machine?
There is no difference between a turning machine and a lathe. They are two names for the same kind of machine
What is the purpose of the sideways of a lathe?
rest your tool on
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.
What Features of the lathe and what accessories can be used?
A lathe is a tool used in woodworking to shape pieces of wood into usable objects. Different types of tools can be used to shape the wood in a desired style.
What is a vtl machinist?
this is a vertical turret lathe you stand the workpiece on a horizontal chuck
What is the function of the lathe apron?
converts rotary motion to straight motion.
How does the saddle of a lathe machine function?
carriage comprises of parts-saddle and apron.
What apron in lathe?
Any apron that is not securely tied in back of the wearer, or that has a torn or frayed edge, presents a risk to the wearer of getting caught in the lathe, pulling the wearer into contact with the fast-spinning material, and causing friction injuries. Thus it is very important to keep your shopwear in good repair, and inspect it every time you use it.
What is the split nut in lathe?
The split nut, also known as half nut enables thread cutting on a lathe. It is engaged around the lead screw (which is housed in the apron attached to the saddle) and moves the saddle in the required direction at the required pitch.
Which turret lathe has rods?
All turret lathes have rods. These rods are called feed rods and their purpose is to transfer mechanical power from the main drive and gearbox of the lathe to the apron attached to the saddle. This enables automatic movement of the saddle enabling unassisted cutting of a workpiece once the feed is engaged.
What is meant by pitch measurement in lathe?
Pitch measurement refers to the distance from one thread to the next when threads are cut on a lathe. Different threads have different pitches and a lathe can be set to to cut to any specified pitch. This is achieved by selecting the pitch and engaging the lead screw on levers located on the headstock, then engaging the half-nut around the lead screw from the apron. With the correct threading tool inserted threads can be cut into the workpiece.
What is half nut mechanism?
A half nut is literally a nut split in half, length wise and makes up the basic half-nut mechanism. Such a mechanism is typically found on a engine lathe. This mechanism can be "open" or "closed" and when closed clamps onto the lead screw of said lathe. This forms a connection between the apron of the lathe sliding on the ways. The apron carries the cross and compound slides, the latter in turn holds the cutting tool. When closed, or "engaged", the movement of the apron moves relative to the rotation of the lead screw. This lead screw is precise in nature and can be described in terms of threads per inch (or per meter or millimeter in case of metric). The lead screw is also connected somehow (there are various methods) to the main motor of the lathe and this ratio of gears can be changed so that many variations of threading, all relative to the thread of the lead screw, can be accomplished on the workpiece being turned/threaded by the screw cutting operation. On a basic older style lathe, the screw begin cut can not be cut in a single pass of the cutting tool. This means that the half-nut may need to be disengaged to reverse the direction of the apron allowing for the cutting operation to be repeated, each time engaging and re-engaging the half nut, until the depth of the screw being cut has reached a final thread depth.
