The 8 Feet Veneer Peeling Plywood Lathe stands as a powerhouse of large-scale log processing, engineered to transform massive timbers into high-quality veneers with exceptional precision. Built to handle logs up to 550 mm in diameter and 2700 mm in length—sizes common in industrial plywood production—this heavy-duty machine delivers veneers ranging from 0.5–4 mm thick with a remarkable ±0.05 mm thickness uniformity.

At its foundation lies a one-piece cast iron bed—heat-treated to 250HB hardness—supported by high-precision linear guide rails that ensure stability during high-speed operation (0–120 RPM). A CNC-controlled hydraulic chuck provides 100kN clamping force to secure logs, while a carbide-tipped peeling knife—adjustable to 0.1mm increments—maintains consistent cutting geometry throughout the peeling cycle.
Key features include an automatic log centering system that reduces setup time by 30% compared to manual positioning, and a self-adjusting knife holder that compensates for blade wear in real time, ensuring consistent veneer thickness even as the knife dulls slightly over extended use.
1. High-Precision CNC Control
The lathe’s advanced CNC system integrates 3D laser scanning technology to map log geometry before peeling, creating a digital profile that guides the cutting process. This scanning—accurate to 0.1 mm—identifies irregularities like knots or taper, allowing the system to generate optimized peeling paths that minimize thickness variations. For example, when processing a 500 mm diameter log into 2 mm veneers, the CNC adjusts feed rate from 5m/min to 3m/min as the log diameter decreases, maintaining uniform thickness across the entire veneer sheet.
2. Heavy-Duty Construction for Longevity
Durability is engineered into every component, starting with the one-piece cast iron bed that undergoes stress-relief annealing at 650°C for 48 hours. This process eliminates internal stresses, ensuring the bed retains ±0.02 mm/m straightness even after 10+ years of continuous operation. The spindle assembly features double-row cylindrical roller bearings that support radial loads up to 5000 kg, while angular contact bearings handle axial forces, maintaining spindle runout below 0.01 mm.
Sealed-for-life lubrication systems throughout the machine—including grease-packed bearings and oil-bathed gearboxes—reduce maintenance requirements to once every 1000 hours of operation. Critical wear components, like the peeling knife holder and log support rollers, are constructed from hardened steel (HRC 58–60) to withstand the abrasive forces of continuous log processing.
3. Versatile Processing Capabilities
The lathe offers unmatched flexibility by accommodating both spindle-based and spindleless peeling methods: spindle mode for smaller logs (100–300mm diameter) requiring precise centering, and spindleless mode for large logs (300–550mm diameter) to maximize yield. A quick-change knife holder allows technicians to switch between standard straight blades and angled blades (for curved veneer production) in 10 minutes, supporting specialty applications like furniture components and architectural moldings.
A high-capacity chip conveyor system (100L/min) removes wood waste efficiently, preventing buildup that could interfere with log rotation. The system also includes a log diameter measurement sensor that automatically adjusts peeling parameters based on incoming log size, reducing operator intervention and ensuring consistent results across variable raw materials.
Plywood Mills: Processes large-diameter logs into structural veneers for 7-ply and 9-ply boards used in heavy construction, where uniform thickness enhances panel strength and load-bearing capacity.
Engineered Wood Factories: Produces glulam (glued laminated timber) cores with precise thickness, ensuring consistent bonding and structural performance in beams and columns for commercial buildings.
Marine Industry: Peels rot-resistant hardwoods like mahogany and teak into veneers for marine plywood, meeting strict standards for water resistance and dimensional stability.
Export Markets: Delivers veneers that meet FSC (Forest Stewardship Council) certification requirements and CE safety standards, enabling manufacturers to access European, North American, and Southeast Asian markets with confidence.
This lathe combines raw power with pinpoint precision, making it an indispensable asset for large-scale wood processing facilities seeking to maximize productivity, material utilization, and product quality in the competitive global plywood market.
