QMJ143SA

Multi-blade Rip Saw

Precision in motion, assurance in delivery

Casting body, robust and stable

High precision and efficiency achieve perfection in every detail

The QMJ143SA is designed for short material processing, with a minimum continuous feeding length of 230mm. It features a track-based frequency-controlled conveyor system that ensures straight and precise material feeding, with an adjustable feed speed ranging from 4 to 30 m/min, meeting diverse processing requirements. The machine is equipped with a rebound prevention safety device, ensuring safe operation, and an automatic centralized lubrication system that continuously maintains the track, extending the machine's service life. Its high-power saw shaft delivers ample cutting power, and the motor specifications can be customized according to needs, providing excellent cutting performance. Ideal for short material cutting in furniture factories, this model is the preferred choice for longitudinal cutting of wide boards in various wood processing plants.
