What is carriage in lathe machine?
carriage is a part of lathe which means to be support cutting tool to give feed to cutting tool and control cutting action.
it stands for military and 16 is its code number it 16 also means assault rifle like m14. You may also see A1, A2, and A3 on the end witch means action number (fully automatic, 3 round burst, selective fire)
Incorrect. A1, A2, and A4 indicate an adoption of a modified variant to the originally adopted design. The A2 differed from the A1 in a number of ways - not just in using three round burst rather than full auto fire, but also in using a heavier profile barrel with a 1 in 7 pitch (vs. the 1 in 12 pitch of the M16A1), different plastics used in the furniture, a different buttstock, different rear sights, and a brass deflector in the upper receiver. M16A3 was never a military nomenclature - Colt coined it. They knew that not all export customers would want to be limited to a three round burst, so they manufactured an M16A2 with an M16A1 trigger group. The A4 differs from the A2 in having an upper receiver with an integral Picatinny rail, and extended feed ramps.

Where does vibration occur most in a lathe machine?
Some major sources of lathe vibration are as follows: 1.) The stock you are turning is not centered properly, or has a lopsided mass. This has the same effect of to much clothes on one side of your wash machine during spin cycle. You can cure this by slowing down the speed you turn at until the roughed stock is more centered. 2.) Take a look at the head stock on your lathe, if it has worn bearings, if the pulleys are out of line or your belt is worn, you will most likely get vibration. 3.) Look at the floor your lathe is on. Is it solid? Cement is the best surface, an flex in your floor will result in lathe vibration. 4.) Look at the stand your lathe is on, is it solid, is it true. A level will let you know if youre base is sagging under the weight of your lathe. Make sure your lathe base is solid and not attached to surrounding walls. The common fixes:
Bring your head stock and tailstock together until they touch. Do they line up perfectly, if not you may have a lathe base or floor that is sagging under the weight. Spin the lathe by hand. Is it smooth? If its rough or bumpy chances are you have worn bearings that need to be replaced. Use a straight edge to make sure all belts and pulleys are in line. Being off center will cause vibration or can cause un-even wear of the belts which in turn will cause vibration. If the belt is worn replace it. Add some weight to your base. The lathe is heavy so any vibration is sent right through your base and magnified. Add weight makes it harder for the lathe to move around and will decrease vibration of an out of round piece of stock.
What is difference between Lathe machine Shaper machine and Milling machine?
Although the planer and shaper are able to machine flat surfaces,there is not much overlapping in their fields of usefulness. They differ widely in construction and in the method of operation. When two machines are compared the following differences may be seen:
1. The planer is especially adapted to large work; the shaper can do only small work.
2. On the planer the work is moved against a stingray tool; on the shaper the tool moves across the work which is stationary.
3. On the planer the tool is fed into the work; on the shaper the work is usually fed across the tool.
What are face plates used for on the lathe machines?
On a wood turning lathe, the faceplate is screwed to the piece of wood, then the faceplate is held in place by the chuck. This facilitates free-wheeling the opposite end for such items as bowls.
Almost similar to a wood turning lathe, the face plate on a metal lathe is a device that is used instead of a chuck. It allows a workpiece to be clamped or bolted to it for machining.
What causes the lathe machine taper problem?
Taper problems on a lathe can be caused by many things. Below are the most likely possible causes and solutions:
- Misaligned tail stock
- In most cases the tail stock can be realigned with its setting screws
- Worn tail stock slides - Send for repair
- Misaligned Head stock
- The head stock can be re-aligned
- Misaligned bed
- The entire machine should be leveled again
- Worn bed ways
- The machine should be sent for regrinding the beds
State how the size of a center lathe is specified?
the size of a lathe can be described by either of the following ways.
1.DISTANCE BETWEEN THE TWO SPINDLES.
2.SWING DIAMETER.ITS THE DISTANCE MEASURED FROM THE SADDLE/CARRIAGE TO THE CENTRE OF THE SPINDLE.
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.

How a lathe machine is specified?
A lathe machine is specified by-
1.The maximum diameter of the workpiece that can be operated on the machine.
2.The distance between the headstock and the tail-stock of the machine.
3.The length of bed of the machine.
What is the meaning of operation in lathe machining?
An "operation" is one step in a manufacturing process. Typically, there are a number of operations required to manufacture any given part, and you try to do as many of them in a single machine setup as possible to save time and cost. Considering lathework, you might have a part that requires this set of steps to make: 1. Rough turn stock / 2. Final turn outside diameter. / 3. Turn snap ring groove / 4. Turn thread undercut / 5. Cut thread / 6. Knurl / 7. Face / 8. Cutoff Each of these steps would probably use a different cutting tool in the lathe, and would be an operation. Depending on the sophistication of the lathe, all the required tools might be loaded into a turret in the sequence they are required. That would be the setup.
What is the type of motor used in running a lathe spindle?
230V/1Ph/50Hz 1HP (0.75 kW)Motor
Capacitor start induction motor ( single phase)
Why is a lathe bed made of cast iron?
Cast iron is used as the "material of choice" for many machinery housings or bases because it is extremely stable in its structure. Certainly it is subject to thermal expansion and contraction, but the crystal structure of cast iron makes it "hold its shape" in applications ranging from machines and machine parts to cookware. And in things like a lathe bed, we need the thing to be "the same" every day and all the time so we get accurate, consistent work. Cast iron also suppresses high frequencies generated during machining.
Note that the ways (the parts of the bed that the carriage slides on), are hardened and machined to provide lasting and accurate surfaces.
What is the difference between a milling machine and a lathe?
A milling machine basically look like a drill press, but with the ability to move the work piece sideways.
A lathe clamp and spin the work piece horizontally and use a stationary tool bit to cut and shape the work piece.
A Tiptronic gearbox is slightly like a normal manual gearbox but with one difference. The gearbox lever can only go foreword (down a gear) or downward (up a gear). If you watch the BTCC or Le Mans in the GT1, 2 or 3 class, you will understand what I am talking about.
What is difference between Conventional Lathe and high speed lathe?
There are many different types of Lathe, the King of all machine tools- as there are many types of Organs ( musical instrument) a High-speed sometimes shortened to (speed Lathe) is a light duty model intended for sheet-metal work and such jobs. one model was used by the Naval Aircraft factory in Great Lakes ( home of the Great Lakes Biplanes- popular with stunt pilots) -and this had a circular speed controller looking something like a ship"s engine room telegraph but calibrated in R.P.M. and direct reading. there may be some specific R.P.M. range that would be taken as ( High Speed). There is an illustration of the Navy lathe in the current and recent Technical Books catalogues of Lindsay"s Publications.
The main difference is the following:
On a CNC Lathe the material to be worked is held in a chuck and rotated around and the tools are clamped. These tools are then moved against the rotating material to cut into it.
On a CNC Mill the tools are held in a chuck and rotated around and the material to be worked is clamped. These tools are then moved against the stationary material to cut into it.
Where can you find wood lath strips?
Lowes sells 1-1/2" wide lath strips. They also can be ripped from 2x4 material, 3/16" thick. Jack L http://www.thewoodshop.20m.com
Accuracy of a lathe depends mainly on?
The accuracy of a lathe depends on the following:
- Skill of the machinist
- Wear on the slides and carriages
- Alignment of both head and tail stock
- Wear on the main spindle assembly
- Wear of the tail stock and in some cases the center
- Types and accuracy of the measuring tools used
You need an internal thread chaser to do it. They come in a set with the external thread chaser.
What are the differences between the new lathe and the old lathe?
I'd have to see the two lathes to tell you, but there are four main reasons a turner replaces his lathe: the new one vibrates less, the new one is larger either in length or in the diameter of the piece it can turn, the new one has a bigger motor, or the new one runs at a slower speed than the old one.
You're asking yourself "wouldn't you want a faster lathe?" No! A turner wants a lathe that has lots of power at slow speeds because it's safer to make the initial cuts on a piece at a really slow speed, and the slower speed will let you make turn larger pieces.
