In which operation the spindle speed on lathe is minimum?
knurling
How do you measure lathe speed?
lathe speed is numerically measured by cutting speed vdn/1000.
What is high speed machining?
It is the process of using high speed spindle rates and lighter passes to achieve rapid material removal.
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.
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.

How are spindle speed changed in the lathe machine?
Using geared head for gear box driven or stepped pulley if belt driven
How do you measure lathe speed?
lathe speed is numerically measured by cutting speed vdn/1000.
What is meant by the term turning wood?
Woodturning is a form of woodworking done on a lathe. A lathe is a woodworking tool that spins a piece of wood at a relatively high rate of speed. The purpose of spinning wood is to form a symmetric shape using tools or sandpaper.
What is the speed of lathe?
The number of rounds per minute.
Why must abrasive grinding wheels be inspected carefully and the spindle speed checked before mounting?
Spindle speeds must not exceed maximum operating speed.
What is the suggested spindle speed for reaming?

What is an all gear lathe?
A lathe in a small wood or metal shop has a motor that connects to the lathe by belt. In a "direct drive" lathe the motor connects directly. I assume that "all gear" means direct drive, no belt. A belt drive protects the motor from damage and reduces vibration of the lathe. In addition, the belt allows you to change the gear ratio and thus the speed of the lathe without changing the motor speed. Belt drive is superior in terms of both performance and longevity.
How do you specify the column drilling machine?
Drilling capacity in steel Tapping in steel Taper in spindle nose Spindle speed range Number of spindle Spindle feed range No of feeds Distance of spindle axis from column surface with spindle Distance between spindle face & floor level Rotation of arm around column Angle of drill head swivel from horizontal Power of spindle motor Distance between drilling spindle axis in horizontal Column traverse along bed Speed of column traverse along bed Total weight of the machine Max. Torque at spindle
What is the spindle speed for the carbide cutting tools?
I thought you knew....
Does electricity generation in dynamo depend on speed of spindle?
Yes
Do I need to be concerned with anything other than the amount of memory in the hard drive?
Spindle speed is very important. Don't accept less than a 7200 RPM spindle speed.
