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.

Why cast iron absorb vibration?
Yes, which is why most machine tool castings are made of cast iron.
How you calculate rated power of lathe machine?
It will be often desirable to know the power which is being consumed in operating a lathe on certain work for which data is required. For most purposes this can be sufficiently approximated by calculating the power of the lathe from the width of the belt and its speed in feet per minute. For such purposes it is usual among mechanical engineers to consider that a one-inch belt traveling a thousand feet per minute will transmit one horse-power. This will give us a key to the entire calculation.
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 repairMisaligned Head stock- The head stock can be re-alignedMisaligned bed- The entire machine should be leveled againWorn bed ways- The machine should be sent for regrinding the beds
Example of products made by using lathe machine?
We use the lathe machine for facing, knurling, grooving, etc... n gen we use all these processes after foundry and casting of a object... We can use lathe for threading, cutters etc.....
Which material used to make a lathe bed?
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 would cause a 92 Toyota to rumble at fast deceleration?
if it is vibration when braking, it is most likely warped brake discs ,which can be skimmed using a lathe or by replacing. if it is vibration when not braking & coming off the power it could be wear in an inner cv joint

Where can I get vibration exercise machines?
Vibra Fit is now offering the most excellent vibrating exercise machine on the Vibration plate exercise and fitness machines for home gym, commercial
Is there a vibration exercise machine that works?
The efficacy of vibration exercise machines is a matter of some debate. The most well known machine is the shake weight, which has been shown to be effective for some people, but the best exercise regimen combines a number of different exercises.

Why cast iron used for bed of lathe?
Any solid material that is capable of cutting ferrous metals are used, but if the family is the most iron. <><><> Cast iron is less prone to warping than other metals. This refers not to the machining of cast iron, but the use of cast iron as the bed of the lathe. Yes, more housing is made ​​of cast iron industrial machines. Because iron does not tolerate the stress. Its ability to cause melting and casting, the theme is good. +++ I assume the question asks why cast-iron is the main material for making the lathe - and in fact most machine-tools. ' It is easy to machine and gives very good bearing surfaces such as the shears on the lathe bed; thanks to its inherent "self-lubricating" and oil-retaining property due its granular structure of iron crystals interspersed with those of graphite - you soon find the graphite when you machine the stuff! ' It has a damping effect - it is not as resonant as steel so reduces vibration. ' Re-writing the first respondent's last sentence as I think he meant: it melts at a relatively low temperature, and its low viscosity when molten greatly facilitates casting intricate shapes.
Any types of woodwork machines?
Some types of machine tools are:Center latheMilling machineShaperHorizontal boring millVertical boring millRadial arm drillSlotting machineCylindrical grinderGear grinder and Gear shaperVarious types of CNC: Lathe, machine center, milling machine, etc.
What would cause vibration in a motorhome between 60 and 65 but doesnt occur before or after?
Tire out of balance is the most likely cause. Have the tires/wheels inspected, rotated, and balanced.
What are the functions of gear train on a lathe machine?
All gearboxes work the same way: there is a gear on the motor, a gear on the thing you're trying to drive, and sometimes a set of gears between the two. The ratio between the gears, plus the RPM of the motor, determines the speed of the workpiece. If the gear on the motor is larger than the gear on the workpiece the RPM of the workpiece will be higher than the speed of the motor. If the workpiece's gear is larger, the workpiece will turn slower than the motor. Given that, though, I've never seen a gearbox on a wood lathe. Wood lathes use belt drive for two reasons, the most important being safety--if you get a catch, a workpiece on a belt driven lathe won't damage you as badly as a workpiece on a gear-driven lathe. Also, belt drive won't feed vibration from the workpiece back into the motor and damage the bearings. Gear drive is used on metal lathes.
