Importance of lathe machines?

Lathe machine is known as mother tool of all other machines tools. It is widely using for making round/ spherical jobs. One of the reasons of development of modern technology and modern industries are due to the contribution of this simple machine.Lathe machines is used for operations like:

Turning i.e workpiece will rotate on spindle against longitudinally moving HSS or Carbide insert turning tool.

Facing i.e producing a flat surface by cross feeding a tool against rotating workpiece.

Shaping or planning on a workpiece is also possible with the aid of some attachments.

Drilling and boring are yet another important operations that can be done on this machine.

knurling,Radius forming,Production of screws and various Milling operations with suitable attachments are its additional scope of operations.

What is lath martensite?

What is monel material?

Monel Alloy

A nickel-copper alloy with high strength and excellent corrosion resistance in a range of media including sea water, hydrofluoric acid, sulfuric acid, and alkalies. Used for marine engineering, chemical and hydrocarbon processing equipment, valves, pumps, shafts, fittings, fasteners, and heat exchangers.

What is the angle between the lathe centers?

A quote from the related link is "Most lathe centers have a tapered point with a 60° included angle to fit workpiece holes with the same angle. ". I am a Mechanical Engineer and I have never seen an angle other than 60 degrees for the lathe center.

What is a faceplate?

Average cutting speed of stainless steel in lathe machine?

Obviously it would depend on the stainless grade because stainless is an alloy, so the speed rate would differ slightly depending on your grade.

The most important factor would be the type of cutter you use, if you are using Carbide cutting tools, with sufficient coolant you can run it at about 90-110 m/p/m (90 to 100 meters per minute)

If you using high speed steel cutters run it no more than about 30m/p/m.

My best advice to you is to ask for the manufactures recommendations they will give you a limit to work in, always start between lowest and middle of manufactures speed recomendations and then work your way up in speed if necessary. If your speed is correct you get a better finish and longer toolife.

Remember that if you run tools at higher speeds you decrease their life, the time taken to cut the material is determined by the feed-rate and not the speed, even on a lathe which has feed set to federate per revolution will only differ slightly.

Hope this helps…

What is a lathe chuck and what are the types of chuck?

A lathe chuck is a device on the driven spindle on the head (headstock) of the machine that holds the workpiece. It grips and spins it. The chuck has "fingers" called jaws that "pinch" the workpiece between them to secure it. Chucks can be 2-, 3- , 4-jaw or more. And the chuck can be self-centering or of the independent type. The self-centering chuck will have a "scroll" of threads behind the jaws that engages them. The scroll is the screw that will close each of the jaws on the workpiece (simultaneously) with the use of a tool to tighten it. And this chuck will automatically center the workpiece in the chuck. Independent chucks will have jaws that must have a tool used on each of them independently to tighten them. And of course, the workpiece will have to be "fooled around with" until it is centered in the jaws. Workholding is a company that sells chucks and has an article with pictures. A link is provided to the site. Additional links are provided to other images. Be sure to at least look at the "6-jaw chuck taken apart" to see the scroll gear that simultaneously closes the jaws. Look closely. The shiney "circles" are not circles at all but are the gradually shaped spiral of the scroll.

How does a lathe work?

a laithe works by a rotating jaw with ur work in the chuck and u can use many laithe tools to cut difrent things off of your work sick bled dont mention

It has a head stock(fixed and is connected to motor) and a tail stock(movable).The tool is moved towards the workpiece (which is driven by motor).Used for making cylindrical sections,tapering,drilling..

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

What is the objective of a lathe machine?

The objective of lathe machine is to remove extra material from the work-piece to make a desired shape with the help of specified tools.

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.

Will running a 60 cycle motor on 50 cycles harm it I am bringing a lathe to Africa on a Mission effort. I am installing a transformer to change 230V to 115V but I am concerned about the frequency?

It is important that you should read see the answer to the Related Question shown below: "Would 120 volts appliances work on 230 volts in Europe?"

<><><>

This question is asking just about the motor. No electronic controls are associated with it.

<><><>

The speed will be different. The motor may heat up more lowering it's total life expectancy. Best you contact a licensed electrician that knows of European devices.

<><><>

As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.

Before you do any work yourself,

on electrical circuits, equipment or appliances,

always use a test meter to ensure the circuit is, in fact, de-energized.
