| In the timber industry, productivity demands are increasing; production is normally measured in lugs per minute - a unit that describes how fast a machine processeslogs and boards. OEMs and timber-processing end users also require machinery that is able stand up to sawmill severe conditions where temperatures alter, vibrations stress and grate machinery. A sawmill normally contains planing, molding, tenoning, and other machines for finishing processes. The largest mills are commonly placed where lumber can be shipped by river or rail, and the design of a sawmill depends upon the mode of transportation. Among required machines there are various types of saws, side trimming shears, woodworking equipment. Below are the main types of saws. Saws are classified into hand-powered and mechanically powered. A rip saw and a cross cut saw are common types. They are both deployed for cutting wood. Mechanical saws are classified into 3 main types determined by how they move the blade into the material. There are circular blade saws, reciprocating blade saws and continuous bandsaws. - A bandsaw is a powerful tool which uses a blade consisting of a continuous band of metal with teeth along one edge to cut various workpieces. The band rides on two wheels revolving in the same direction. Bandsawing produces a consistent cutting action because of an equally distributed tooth load. Bandsaws are deployed for woodworking and are particularly useful for cutting out curved shapes, but can also be deployed to produce straight cuts. The radius of a curve that can be cut with a particular saw depends on the width of the band and its lateral flexibility. - A circular saw is a metal disk with saw teeth on the edge as well as the machine which causes the disk to spin. It is a machine for cutting wood or other materials and may be hand-held or table-mounted. It can also be deployed to make narrow slots. These days circular saws are mechanical. - In reciprocating blade saws, there are jigsaws, which are usually hand-held, and are frequently used in woodworking to cut out shapes. They can be fitted with blades for wood or metal. They are more powerful than jigsaws. For more information about mill machinery, please visit www.pilorama.org. |
