A Bandsaw is a power tool which uses a blade consisting of a continuous band of metal with teeth along one edge to cut various workpieces. The band usually rides on two wheels rotating in the same plane.
Horizontal bandsaws hold the workpiece stationary while the blade swings down through the cut. This configuration is used to cut long materials such as pipe or bar stock to length. Thus it is an important part of the facilities in most machine shops. Small horizontal bandsaws typically employ a gravity feed alone, retarded to an adjustable degree by a coil spring or through a power feed mechanism; on very large industrial models, the rate of descent is usually controlled by a hydraulic cylinder bleeding through an adjustable valve.
A vertical bandsaw, also called a contour saw, keeps the blade's path stationary while the workpiece is moved across it. This type of saw can be used to cut out complex shapes and angles. The part may be fed into the blade manually or with a power assist mechanism.
Feeding Mechanisms can be (a) Gravity (b) Hydraulic Feed (c) Power/Leadscrew feed
Design can be (a) Single Column (b) Double Column (c) Pivot or Scissors Type
