The feed system of the rotary cutting machine is unstable, affecting the precision of the rotary cutting
Rotary cutting machine is a key equipment in wood processing, and the stability of its feed system directly affects the rotary cutting accuracy of veneer. However, in actual production, the instability of the feed system occurs frequently, leading to uneven thickness and rough surface of the veneer, which seriously affects product quality.
1. Reasons for the instability of the feed system
(1) Mechanical wear: After long-term use, transmission components such as lead screws and guide rails wear out, resulting in gaps or jamming during the cutting process, which affects the cutting accuracy.
(2) Hydraulic system fluctuation: If the performance of the hydraulic pump or valve components decreases, it will cause unstable oil pressure and inconsistent feed speed of the tool holder.
(3) Control system error: Abnormal feedback from servo motors or encoders leads to inaccurate control of the feed position.
(4) External interference: Voltage fluctuations or mechanical vibrations may interfere with system operation and exacerbate instability.
2. Impact on rotary cutting accuracy
The instability of the feed system can lead to an increase in the thickness deviation of the veneer, which affects the quality of subsequent plywood pressing. At the same time, the shaking of the knife holder can cause the surface of the veneer to tear, increase the scrap rate, and reduce production efficiency.
3. Solutions
Regularly maintain transmission components and replace worn parts; Optimize the stability of the hydraulic system; Upgrade the high-precision servo control system and strengthen equipment vibration reduction measures to improve rotary cutting accuracy and product quality.
