a flanged or tapered or threaded bar that grips a workpiece to be machined in a lathe..
What is a dead center used for?
A dead center (one that does not turn freely, i.e., dead) may be used to support the workpiece at either the fixed or rotating end of the machine. When used in the fixed position, a dead center produces friction between the workpiece and center, due to the rotation of the workpiece.
What does turning between Centres mean?
What might be thought of as the simplest way of holding a workpiece goes back to the primitive lathe. It is to hold the workpiece between two centers. To do this one center it fitted in the socket in the spindle and another in the tailstock.
What personal protection should you wear when working on a lathe?

What does lathe mean?
A lathe (/leɪð/) is a machine tool that rotates a workpiece about an axis of rotation to perform various operations such as cutting, sanding, knurling, drilling, deformation, facing, and turning, with tools that are applied to the workpiece to create an object with symmetry about that axis.
What does mandrel mean?
1a : a usually tapered or cylindrical axle, spindle, or arbor inserted into a hole in a piece of work to support it during machining.
Why is it important to locate the center carefully?
It is very important that the work to be turned is carefully centered. If this is not done then a big chip will be removed from one side of the diameter and a small chip from the opposite. This unevenness of cut takes more time and may cause inaccuracy.
How do you use a dead center on a lathe?
The proper use or method to use both DEAD and LIVE Centers is when turning a part between centers. Remove the chuck from the lathe and insert a DEAD CENTER in the SPINDLE NOSE. Use the LIVE CENTER in the TAILSTOCK.
What is straight turning?
[′strāt ′tərn·iŋ] (mechanical engineering) Work turned in a lathe so that the diameter is constant over the length of the workpiece.
What are the differences between live center and dead center?
To put it simply a dead center is just that – dead. It has no moving parts. It is really nothing more than a metal shaft with a point. A live center is similar, but the shaft has a bearing that allows it to turn.

What is the difference between headstock and tailstock?
A tailstock, also known as a foot stock, is a device often used as part of an engineering lathe, wood-turning lathe, or used in conjunction with a rotary table on a milling machine. … A tailstock has a Dead Center, while headstock has Live Center.
What are lathe dogs used for?
A lathe dog is a dog designed to be clamped on a work piece to allow it to be revolved by a lathe face-plate. Lathe dogs are generally provided in straight-tailed or bent-tailed form. Bent-tailed dogs are able to engage directly with a face-plate slot or a chuck jaw but can crowd work off centre.
What is a lathe faceplate used for?
A lathe faceplate is a basic workholding accessory for a wood or metal turning lathe. It is a circular metal (usually cast iron) plate which fixes to the end of the lathe spindle.
Is wood turning dangerous?
The piece of wood is the dangerous part. It is moving up to 4000 rpm depending on settings and lathe. … Being too aggressive can either stop the wood, (which isn’t good for the lathe) or try and yank the turning tool out of your hand, which is very dangerous to the turner.
