Veneer rotary cutting is one of the core processes in plywood manufacturing. Its purpose is to continuously peel logs into veneers with specified thickness and width using a rotary lathe. The quality of rotary cutting directly affects plywood strength, flatness, bonding performance, and surface quality.
Complete Veneer Rotary Cutting Process:
Log Receiving → Log Sorting → Log cutting → Hydrothermal Treatment → Debarking→ Rotary Peeling → Clipping & Sizing → stacking→ Drying → Grading & Repair → Storage
Detailed Description of Each Process:
1,Log Receiving and Sorting
After arriving at the factory, logs are sorted according to species, diameter, length, curvature, and defects.
2,Log Bucking and Cutting to Length
Logs are cut into required lengths according to rotary lathe specifications.
3,Hydrothermal Treatment
Logs are steamed or soaked in hot water to improve wood plasticity and reduce peeling resistance.
4,Log Debarking
Bark must be removed before peeling to prevent sand and impurities from damaging knives.
5,Veneer Rotary Peeling
The rotary lathe continuously peels the rotating log into a continuous veneer sheet.
The log rotates around its axis while the knife advances radially, cutting the wood into continuous thin sheets.
6,Veneer Clipping and Sizing
Continuous veneer sheets are clipped into standard panel sizes.
7,stacking
the peeled veneer can be stacked automatically .if wants to reducing the investment cost, the stacking machine is also not needed.
8,Veneer Drying
Wet veneers are dried to the required moisture content.
9,Veneer Grading and Repair
After drying, veneers are graded according to quality standards.
10, Stacking and Storage
Graded veneers are stacked and stored according to specifications.
