Working Principle

Single-end active drive. One active spindle provides the main driving force for rotation. The other end is supported and centered by a passive tailstock (often a conical or spherical center).

Dual-end synchronous drive. The log is driven synchronously and in the same direction by two active spindles at both ends, which provide powerful clamping force and rotational torque.

Work Process

1.Log Loading & Centering: The log is positioned, and the tailstock advances to support one end.

1.Log Loading & Alignment: The log is positioned between the two spindles and aligned via hydraulic or mechanical means.

2.Spindle Clamping: The main spindle extends, pierces, and clamps the other end of the log.

2.Dual-end Synchronous Clamping: Both spindles extend synchronously, pierce, and clamp the two ends of the log.

3.Peeling: The main spindle rotates the log, the tool carriage feeds, and peeling begins.

3.Peeling: The dual spindles rotate the log synchronously, the tool carriage feeds, and peeling begins.

4.Completion: The process stops when the predetermined core diameter or the tailstock's limit is reached.

4.Completion: The process stops at the predetermined core diameter, and both spindles retract.

Advantages

1.Simple structure, lower manufacturing and purchase cost.

1.High driving torque, excellent rigidity, and extremely stable operation.

2.Relatively easier maintenance.

2.Wide processing range, especially excels at handling large-diameter, long logs.

3.Suitable for shorter or medium-diameter logs.

3.Generally higher peeling precision and veneer quality.

4.High level of automation, the mainstream choice for modern production lines.

Disadvantages

1.Limited driving torque and rigidity, not suitable for extra-large/hardwood logs.

1.Complex structure, higher manufacturing cost and price.

2.Tailstock support may cause end damage or jumping of the log.

2.Complex hydraulic and control systems, requiring higher maintenance skills.

3.Less stable than dual-spindle models when peeling extra-large logs.

3.Generally requires a larger footprint.

Primary Application Scenarios

Suitable for small to medium-sized wood processing plants, handling small-diameter logs, short logs, or scenarios with moderate throughput requirements.

Suitable for large plywood manufacturers and continuous production lines as core equipment for efficiently processing large-diameter, long-length logs.
