What is the minimum cutting thickness of a cardless rotary cutting machine in millimeters
The minimum cutting thickness of a cardless rotary cutting machine directly determines the utilization rate of wood and the added value of the product. With the deep integration of mechanical manufacturing and numerical control technology, the minimum cutting thickness of modern cardless rotary cutting machines has exceeded traditional limits, forming a multi-level technical system.
Precision leap under technological iteration
Early mechanical cardless rotary cutting machines relied on cam feed structures, and the minimum cutting thickness generally remained in the range of 0.6-0.8mm. With the popularization of servo motor drive technology, CNC equipment achieves nanometer level control of tool gate clearance through synchronous feed system, allowing the minimum cutting thickness to be reduced to 0.3mm. For example, the SLXC1500JG CNC equipment produced by a certain enterprise in Yunnan can stably output 0.28mm ultra-thin single board with a processing length of 1380mm through dual servo motor closed-loop control, and the flatness error of the board surface is controlled within ± 0.05mm.
Material adaptation and process optimization
Some manufacturers have optimized the rigidity of the tool holder and the chrome plating process of the drum to maintain a thickness tolerance of less than 0.1mm even during extremely thin cutting of 0.2-0.3mm for eucalyptus and poplar fast-growing forests with small diameter timber. The HW-1300 equipment manufactured by Weihai Hanwei is designed with a dovetail slide and shock-absorbing secondary slide. With a high-speed rotary cutting speed of 100m/min, the minimum wood core diameter can be compressed to 28mm, and the veneer yield can be increased by 12%.
The technological boundaries of cardless rotary cutting machines are still expanding. With the application of linear motor drive and AI thickness compensation system, the future 0.1mm nano rotary cutting technology is expected to enter the industrial stage, opening up a new path for high-value utilization of wood under the circular economy.
