Processing Technology of bare Core
The quality of core affects the quality and cost of blockboard. Therefore, the material and processing technology of core are the key sections in the production of blockboard. A kind of
1. Core strips of bare Core and Its Processing
There are three kinds of processing technology for the core bar: A. The dried plate is planed on two sides, and the core bar is sawn by a multi-slice fine photosynthetic gold saw. The planed surface becomes the side of the strip, and the sawing surface becomes the front of the strip. Therefore, the core bar is sawn by multi-slices to determine its thickness. The processing efficiency is high, the size accuracy of the core bar is high, and the material loss is small, but the processing size of the material is generally required. B. After drying, the board is processed into specification wool strips, or the wet material is processed into wool strips and then dried. The wool strips are processed into core strips by four-sided planer. The processing efficiency is high, the core bar is smooth on all sides, and the accuracy is high, but the yield is low. C. Core bars are made from wood or wood-processing edge leftovers by common sawing machine and planer. It has flexible requirements for materials and can be used for large and small diameter wood and various wood scraps, but the accuracy of machine tools and the level of operators will affect the processing.
