QMB620AT multi-spindle layout is designed for stable, efficient, and high-precision four-side moulding.
High-strength cast-iron machine bed provides excellent rigidity, structural stability, and long-term machining accuracy.
Fully enclosed safety guarding reduces operating noise and improves machine safety and workshop cleanliness.
Grooved positioning guides help prevent material deviation and sticking for smoother four-side machining.
Cylinder-controlled segmented pressure units ensure stable workpiece holding and smooth high-speed feeding.
CLSJ90 side chain conveyor supports reliable material handling alongside the movable worktable.
Grooved positioning guides help prevent material deviation and sticking for smoother four-side machining.
Internationally recognized electrical components provide reliable control, stable performance, and long service life.
Specially treated hard-chrome worktable provides excellent wear resistance, smooth feeding, and long service life.
International-brand variable-frequency drive provides stable performance and convenient feed-speed adjustment.
Features
- The feeding system uses 9 active feed rollers — 7 upper and 2 lower — for smooth and stable material feeding during continuous production.
- A single upper spindle and double lower spindle configuration enables efficient four-sided planing and profiling of solid wood products.
- The upper spindle uses a backward chip-breaker structure designed to reduce the risk of cutter collision during machining.
- High-precision spindles operate at 6,800 r/min, while the chainless universal transmission shaft provides smooth and powerful feeding.
- The high-strength cast-iron machine bed, hard-chrome-treated working surfaces, centralized lubrication and enclosed safety cover support long-term industrial operation.
