The integral cast machine body and rear support column provide excellent rigidity, vibration resistance and long-term structural stability.
The precise spindle components ensure sufficient strength and rigidity, with stable performance and high precision.
A hardened gear reducer and frequency inverter provide smooth, powerful and reliable material feeding during continuous production.
The forced-lubrication system maintains an oil film between the chain track and guide rails and stops feeding when oil is insufficient.
The precision-machined saw arbor provides excellent strength, rigidity and rotational accuracy for smooth, stable multi-blade cutting
Frequency-controlled feeding from 3–24 m/min allows the feed rate to match different wood species and cutting requirements.
The upper pressure roller assembly is electrically raised or lowered for fast setup according to the workpiece thickness
Clearly marked controls and operating indicators provide convenient machine setup and straightforward daily operation
Branded industrial electrical components provide dependable control, stable machine performance and extended service life.
Three anti-kickback devices—two upper and one lower—help prevent workpiece rebound and improve operator safety.
Safety limit switches protect the lifting mechanisms from excessive travel and support reliable machine adjustment.
The precision-machined saw arbor provides the strength, rigidity and rotational accuracy required for stable multi-blade cutting.

Features

The integrally cast machine body undergoes multiple aging treatments and precision machining, providing excellent rigidity, reduced vibration and stable long-term performance.
The precision spindle assembly provides sufficient strength and rotational stability for accurate multi-blade cutting of solid wood materials.
The hardened reducer and variable-frequency feeding system deliver smooth, powerful material movement with easily adjustable feeding speeds.
Wear-resistant crawler chain plates and V-shaped guide rails minimize long-term wear and help maintain accurate workpiece guidance.
Four pressure rollers, multiple anti-kickback devices, centralized lubrication and safety limit protection improve feeding stability, operational safety and component life.
