A lathe ( /ˈleɪð/) is a machine tool which rotates the workpiece on its axis to perform various operations such as cutting, sanding, knurling, drilling, or deformation with tools that are applied to the workpiece to create an object which has symmetry about an axis of rotation.
Lathes are used in woodturning, metalworking, metal spinning, and glass-working. Lathes can be used to shape pottery, the best-known design being the potter's wheel. Most suitably equipped metalworking lathes can also be used to produce most solids of revolution, plane surfaces and screw threads or helices. Ornamental lathes can produce three-dimensional solids of incredible complexity. The material can be held in place by either one or two centers, at least one of which can be moved horizontally to accommodate varying material lengths. Other work-holding methods include clamping the work about the axis of rotation using a chuck or collet, or to a faceplate, using clamps or dogs.
Examples of objects that can be produced on a lathe include candlestick holders, gun barrels, cue sticks, table legs, bowls, baseball bats, musical instruments (especially woodwind instruments), crankshafts and camshafts.
Lethe
Give me the drink of the fluid
That disintegrates
And lend me the sweet balm and blessing
Of forgetfulness, empty and strong
Hold me near, unravel the stars
As I speed through the heavens
Speed through the night
For you are my blade and my rope
Your are my
Lethe
In currents of cobalt
You storm through my heart
To sever, to puncture
The memories that burn
Let sweep through the arteries
In sharp stabs of pain
Your talonlike fingers to kill me again
Steal me, invade me and charge me again
For I burn and I shudder
Burn with each movement of
So, cleansed through a floodlight
I appear; reforged and renewed
Caressed by the sweet balm and blessing
Of forgetfulness, empty and strong
Lethe,
Hold me near, my one friend and guide
As I drown through your fingers
Drown through your love
For you are the life I hate
You are my
Lethe
Drag me down, in passionate sighs
With the ocean above me
And flames in my eyes
And grant me a life I can live
