| Logging, and the logging machinery required in the industry, is gaining popularity, both since wood products which are in great demand and for an alternate source of heat. OEMs and lumber-processing end users also require machinery which is able stand up to mill conditions where temperatures fluctuate, dust badly damages machinery.
A sawmill may be equipped with planing, molding, tenoning, and other pieces of machinery for finishing processes. The largest sawmills are ordinarily placed where lumber can be shipped by river or railroad, and the design of a sawmill depends upon the type of shipment. Among required machines there are various types of saws, side trimming shears, woodworking equipment. In this article we will feature the main types of saws.
Saws fall into hand-held and mechanically powered. Two common types are the rip saw and the cross cut saw.
Mechanically powered saws fall into three major types determined by how they move the blade into the material. Specialists distinguish circular blade saws, reciprocating blade saws and continuous band saws.
- A CIRCULAR SAW is a blade with saw teeth on the edge as well as the machine which makes the disk spin. It is an instrument for cutting wood or other materials and may be handheld or table-mounted. It can also be used to manufacture narrow slots. These days circular saws are almost exclusively powered by electricity.
- In RECIPROCATING BLADE SAWS, there are jigsaws, which are ordinarily hand-held, and are normally used in woodworking to cut out shapes. They can be fitted with blades for wood or metal. They are more powerful than jigsaws.
- A BANDSAW is a powerful tool which uses a blade consisting of a continuous band of metal with teeth along one edge to cut diverse workpieces. The band rides on two wheels revolving in the same plane. Bandsawing produces a uniform cutting action because of an evenly distributed tooth load. Bandsaws are used for woodworking and are especially useful for cutting curved shapes, but can also be deployed to produce straight cuts. The radius of a curve which can be cut out with a particular saw is dependent upon the width of the band and its lateral flexibility.
