What are the requirements for rotary cutting machines in the production of veneer from hardwood logs
Hardwood logs have higher requirements for the performance of rotary cutters due to their hard material and complex texture. Firstly, high-precision control is crucial. When rotary cutting hardwood, the tool angle parameters need to be precise to the grinding angle of 18-23 ° and the back angle of 1-3 °. The clearance error of the pressure gauge needs to be controlled within a very small range to ensure uniform thickness of the veneer and avoid back cracks and surface cracks. For example, a CNC rotary cutting machine can achieve a single board thickness error of ≤± 0.05mm by driving a precision screw feed through a servo motor, meeting the quality requirements of high-end furniture for single boards.
Secondly, the rigidity of the equipment needs to be strengthened. Hardwood has high cutting resistance, and the rotary cutting machine needs to use high-strength card shafts, double steel roller pressure gauges, and other structures to prevent the wood segments from twisting or slipping. The hydraulic double card shaft rotary cutting machine can automatically switch between different sizes of card heads, adapt to different diameter wood segments, reduce the diameter of the wood core, and improve the yield rate.
In addition, automation and adaptability cannot be ignored. The CNC cardless rotary cutting machine can automatically adjust the feed speed to adapt to the characteristics of different wood species and reduce manual intervention. At the same time, the equipment needs to be equipped with a laser or mechanical centering system to ensure the stability of the wood section rotation and avoid the problem of broken veneer caused by the bending or sharpness of the logs.
