The integral cast machine body and rear support column provide excellent rigidity, vibration resistance and long-term structural stability.
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 QMJ145H Top-Spindle Multi-Blade Rip Saw is designed for the simultaneous longitudinal cutting of wide and thick solid wood workpieces.
- The machine body and rear supporting column use heavy-duty cast construction. Multiple aging treatments and precision machining provide excellent rigidity, stable operation and reliable long-term accuracy.
- A precision-manufactured saw spindle supports multiple circular saw blades for cutting one board into several strips in a single pass. The hydraulic outer spindle support stabilizes the far end of the saw arbor and helps maintain cutting accuracy under heavy loads.
- The chain-track feeding system combines a hardened gear reducer with frequency-inverter control, providing smooth and powerful feeding with adjustable speeds from 3–24 m/min.
