Wood rotary cutting
The so-called rotary cutting is to make the shaft rotation of the wood section, and the rotation of the blade parallel to the axis of the wood section for linear feeding motion, cutting the cutting process along the direction of the wood annual ring.
Rotary cutting is the most important part of the production process of wood-based panels, and its quality directly affects the final quality of wood-based panels.
Rotary cutting is divided into card cutting and cardless cutting. Card cutting is mainly for processing large diameter wood, while cardless cutting is processing small diameter logs.
The rotary cutter is also one of the main equipment for producing veneers, and in a sense, it is used more widely than the planer. Rotary cutting machine can be divided into two types: concentric rotary cutting and eccentric rotary cutting according to whether the wood segment rotates around its own axis. Concentric rotary cutting machine is divided into two types: card shaft rotary cutting machine and non-card shaft rotary cutting machine. Eccentric rotary cutting can achieve a beautiful radial pattern, but the productivity is lower than concentric rotation.
Rotary cutting machines are generally large in size and complex in structure. Before the machine is installed, the logs are centered. If the centering is not accurate, the intermittent veneer strips or narrow veneers will be unscrewed when the cutting is started. The more broken boards or narrow single boards, the more sapwood boards are lost, which is not conducive to continuous production. The logs are curved, the sections are irregular, and the ends of the ends (tips) are easy to cause the unscrewed veneers to be broken veneers, which wastes wood. And when the diameter of the log is reduced to a certain extent, it can no longer continue to cut (that is, the remaining wood core causes wood waste).
A high quality rotary cutter is a necessary condition for obtaining a good veneer. If you have a need for a rotary cutter, we can offer different grades of rotary cutter material.
