1.Log Pre-processing: Inspect logs to ensure they are free from severe decay, insect damage, cracks, or other defects, and that their diameter and length meet processing equipment requirements. Remove bark, branches, and other impurities. Depending on the wood's moisture content, perform appropriate drying to control moisture levels between 12% and 20%. For warped wood, straightening treatment may be applied.

The production process of a rotary cutting line typically includes the following steps:
Product A：Spindleless Veneer Peeling Machine
2. Log Conveying: The ends of the logs are cut off using a crosscut saw, after which the cut logs are transported by the feeder to the log debarker.
3. Halo Centering and Debarking for Rounding: The debarking machine processes logs to remove bark and achieve a uniform round shape, ensuring the outer diameter is more consistent and preparing the logs for subsequent rotary slicing. Some rotary slicing production lines may also be equipped with halo centering devices to precisely determine the log's center position, thereby enhancing slicing accuracy.
4. Rotary Cutting: After rounding, logs are fed through a loader into the combined rotary cutting and shearing machine. Processing parameters such as cutting speed, feed rate, and slice thickness are set based on wood properties and product requirements. Typically, cutting speed ranges from 50 to 150 RPM, feed rate from 0.5 to 2 mm per revolution, and slice thickness from 0.2 to 3 mm. During rotary cutting, the tool rotates and cuts the log, producing continuous veneer sheets.
5. Veneer Conveying and Shearing: The rotary cutting and shearing machine shears the sliced veneer, which is then conveyed via the veneer conveyor line to the stacking machine. The conveyor line typically operates at speeds ranging from 30 to 120 meters per minute.
6. Graded Stacking: The stacking machine automatically grades and stacks individual boards. Utilizing image acquisition and processing technology, it employs cameras to perform real-time scanning of board surfaces. By analyzing RGB images and color difference characteristics, it identifies surface quality to determine grading categories, then stacks boards in an orderly manner according to the grading results.

Product B：Spindle Veneer Peeling Machine
1. Log Handling & Debarking
Equipment: Log deck, conveyors, Debarker.
Process: Logs are loaded onto the line. A debarker (typically a rotating ring with carbide-tipped cutters or hydraulic knives) removes the bark completely. This is critical to prevent dirt and abrasives from damaging the peeling knife downstream.
2. Log Conditioning (Steaming/Vat Heating)
Equipment: Steam vats or hot water vats.
Process: Debarked logs are soaked in hot water or steamed for several hours. This plasticizes the lignin in the wood, making it softer and easier to peel. This step drastically reduces peeling defects and energy consumption, resulting in a smoother, continuous sheet of veneer.
3. Lathe Charging & Centering
Equipment: Charging arms, Spindleless Lathe Charger (modern) or traditional spindle centering device.
Process: The conditioned log is mechanically positioned and centered precisely on the lathe's axis. Modern spindleless lathes grip the log from the outside with powered rollers, allowing for processing of the entire log length with almost zero waste, unlike older lathes that used spindles driven into the log ends.
4. The Core Machine: Spindle(less) Veneer Peeling Lathe
Equipment: Veneer Peeling Lathe (the heart of the line).
Process: The centered log is rotated at high speed against a extremely sharp, horizontal peeling knife. The knife advances continuously, shaving off a continuous sheet of veneer of a predetermined thickness (e.g., from 1.5mm to 4.0mm for core stock). The modern "spindleless" design is now industry standard for efficiency.
5. Veneer Clipping & Sorting
Equipment: Veneer Clipper.
Process: The continuous ribbon of veneer coming from the lathe is conveyed at high speed to a clipper. An optical scanner identifies defects (knots, holes) and determines the optimal place to cut. The clipper automatically cuts the veneer into full-width sheets of required lengths. A sorting system then diverts the sheets by grade (e.g., based on the number of defects).
6. Veneer Drying
Equipment: Veneer Dryer (typically a jet-type or mesh-belt continuous dryer).
Process: The wet, clipped veneer sheets have a very high moisture content from the conditioning process. They are conveyed through a multi-section dryer where hot air is blasted onto both surfaces. This reduces the moisture content to a precise level (typically 6-12%) suitable for gluing and ensures dimensional stability in the final panel product.
7. Veneer Stacking & Patching (Optional)
Equipment: Stackers, conveyors. Some lines may have automatic patching machines.
Process: The dry, graded veneer sheets are stacked according to grade and size. For higher-quality lines, sheets may go through a patching station where defects are cut out and replaced with sound wood plugs, or where multiple small sheets are edge-glued together into full sheets.
