For global timber processing and pallet manufacturing enterprises, selecting an efficient and reliable automatic saw mill machine is the key to lowering labor costs and maximizing timber yield. Jinjiang Shenggong Machinery Manufacturing Co., Ltd. (Shenggong), a renowned wood cutting machinery manufacturer in China, draws on 46 years of technical expertise and heavy-duty manufacturing technology to provide global B2B buyers with high-quality wood cutting saw mill machine products and comprehensive customized production line solutions, enabling seamless transformation from whole logs into standardized lumber.

Manufacturing Capabilities: 46 Years of Factory Heritage and Strength

Founded in 1980, Jinjiang Shenggong Machinery Manufacturing Co., Ltd. (Shenggong) is located in the Wuli High-Tech Industrial Park and Yinglin Town Hede Industrial Park in Jinjiang, Quanzhou, Fujian Province, China. Positioned near the airport with convenient transportation networks, the factory covers an area of 11,600m², employs 150 staff members, and houses 8 automated production lines alongside 16 heavy-duty manufacturing machines. The company holds over 15 national patents and European CE certification, collaborating with 25 supply chain partners to support flexible customized production line solutions.

Product Advantages: Upper and Lower Double-Shaft Multi-Blade Cutting

As the flagship model of the 142 upper and lower saw shaft series, this machine is specifically engineered for processing wooden pallets and construction lumber. Featuring a 3D upper and lower dual-shaft structure, it overcomes traditional single-shaft limitations such as restricted cutting depth and blade deflection, enabling synchronized multi-blade cutting to process multiple boards in a single pass.

Weighing 2,500 kg with overall dimensions of 2,950*1,850*1,580 mm, the heavy-duty body effectively absorbs micro-vibrations during high-speed operation. Paired with an 80 mm high-precision spindle, it minimizes thermal blade deformation. Powered by a 56.2 kW motor system compatible with 3 HP - 380V, 50Hz (customizable), it supports variable feed speeds of 0-23 m/min, balancing high output with smooth cutting surfaces.

Manufacturing Process: Heavy-Duty Annealing and Precision CNC Machining

Shenggong adheres to rigorous heavy machinery manufacturing standards to ensure superior precision and durability of the machine itself:

• Heavy Frame Annealing: The welded 2,500 kg heavy-duty machine frame undergoes high-temperature annealing heat treatment to eliminate internal structural stresses, guaranteeing zero frame deformation during long-term continuous operation.
• High-Precision Spindle Machining: The core 80 mm diameter spindle is forged from high-strength alloy steel and refined through multi-pass CNC grinding and dynamic balancing tests, maintaining radial runout within micron-level tolerances.
• Precision Transmission & Assembly: The concentricity of the 10 upper and lower feed rollers and the alignment of the standard 2 m long feeding and discharge auxiliary frame are calibrated on precision machine tools, ensuring smooth, vibration-free, and low-noise operation.

Product Applications: Multi-Scenario Longitudinal Log Processing

As core equipment in primary timber processing, Shenggong's fully automatic multi-blade saw efficiently performs longitudinal cutting on whole logs or rough square timber, turning raw logs into standardized industrial lumber in a single pass:

• Log-to-Board Cutting: Longitudinal slicing of whole logs into uniform flat boards for furniture manufacturing, construction formwork, frame housing, and flooring substrates.
• Pallet Blocks & Crate Lumber: Precision cutting of logs into standard square timber and runners, tailored for automated assembly lines producing export pallets (e.g., EPAL) and packing boxes.
• Structural Construction Timber: Rapid processing of large-section wooden beams and square timber to satisfy load-bearing requirements in timber architecture and engineering.
• Sapwood and Heartwood Separation: Strategic blade spacing configuration allows simultaneous separation of outer sapwood from inner high-grade heartwood, facilitating graded selling and value maximization.
• Continuous Processing for Long Logs: Supported by the standard 2 m long extended auxiliary table, the system handles logs with lengths ≥850 mm or longer continuously without deviation or warping.

Purchasing Decisions: High ROI and Full-Lifecycle Support

When evaluating equipment procurement, B2B buyers focus on return on investment (ROI), timber yield, and post-purchase assurance:

• Substantial Labor Savings: A single multi-blade saw with 56.2 kW total power and a feed speed of 23 m/min matches the single-shift output of 4 to 6 traditional single-blade saws, reducing sawing labor costs by over 60%.
• Increased Timber Yield: Thanks to precise gasket specifications (Φ108*Φ70) and a high-stability spindle system, timber yield increases by 5% to 8%, generating substantial material cost savings over long-term production.
• Full-Lifecycle Service: Shenggong offers pre-shipment load testing, English technical drawings, European CE certification documentation, genuine spare parts supply, and remote video guidance to ensure worry-free operation worldwide.
