In the lumber industry, productivity demands are increasing; production is usually measured in lugs per minute - a unit that describes how rapidly a machine processeslogs and boards. OEMs and lumber-processing end users also require machinery which is able resist sawmill conditions where temperatures fluctuate, dust damages equipment. A sawmill may be equipped with planing, molding, tenoning, and other machines for finishing processes. The largest mills are commonly placed where lumber can be delivered by river or railroad, and the design of a sawmill depends upon the mode of shipment. Among required machines there are diverse types of saws, side cutters, woodworking machinery. In this article we will feature types of saws. Saws are divided into hand-held and mechanical. The most common types are the rip saw and the cross cut saw. Automatically powered saws are classified into three major groups defined by how they move the blade into the wood. There are circular blade saws, continuous bandsaws and reciprocating blade saws. - A CIRCULAR SAW is a metal disk or blade with saw teeth on the edge as well as the machine which causes the disk to spin. It may be hand-held or stationary. It can also be used to make narrow slots. Now circular saws are almost exclusively powered by electricity. - RECIPROCATING BLADE SAWS are usually handheld, and are commonly deployed in woodworking to cut out shapes. They can be fitted with blades for wood or metal. They are more powerful than jigsaws. - A CONTINUOUS BANDSAW is a power tool with a blade consisting of a continuous band of metal with teeth along one edge to cut various workpieces. The band rides on two wheels rotating in the same direction. Bandsawing produces a consistent cutting action because of an evenly distributed tooth load. Bandsaws are used for woodworking and are particularly valuable for cutting out curved shapes, but can also be used to produce straight cuts. The radius of a curve that can be cut with a particular saw is determined by the width of the band and its lateral flexibility.
