A lathe is a machine tool which spins a block of material 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 glassworking.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 is held in place by either one or two centers,at least one of which can be moved horizontally to accommodate varying material lengths.Examples of objects that can be produced on a lathe include candlestick holders,cue sticks,table legs,bowls,baseball bats,musical instruments (especially woodwind instruments),crankshafts and camshafts.我這個更合題意
