Saw machine classification
1. Band saw
Band saw is currently the most popular way of log processing in China, and it has occupied the dominant position of domestic log processing in the past few decades. Band saw processing has the advantages of low requirements for logs, high manual controllability and low mechanical price. However, the production efficiency is low. With the increase of labor wages, the cost of processing one cubic log of logs is also increasing. In some developed areas, there is even a shortage of band saw workers. These all restrict the emergence of domestic enterprises capable of professional and large-scale processing of logs to a certain extent, most of which are small units of family workshops engaged in the primary processing of wood.
2. Frame saw
The disadvantage of the frame saw machine is that it cannot be sawed reasonably according to the defect of the wood. The yield of the finished board is lower than that of the band saw machine under the same conditions. The quality of the logs is high, and the processed wood must be graded before sawing and quality sorting. The reciprocating motion of the saw frame produces huge inertia and vibration, which increases the wear and limits the improvement of the cutting speed. Therefore, the production efficiency is also limited to a certain extent.
3. Circular saw
The circular saw multi-blade saw represents the most advanced log processing technology in the world. With the development and maturity of circular saw technology, circular saw processing technology will become the mainstream of log processing technology. In developed Europe, circular saw technology has replaced traditional band saw processing technology.
