Quick-lift short material device, this mechanism effectively improves the smoothness of short material feeding. The auxiliary feeding wheel has a transmission function, making feeding easier. The feeding wheel can be lifted to facilitate the replacement or adjustment of the tool.
Efficient dust removal, the new dust suction structure can more effectively absorb wood chips. It minimizes the dents on the surface of the finished product and effectively controls the noise.
Feeding inverter. Digital display, convenient operation, reduce, energy saving, reduce mechanical speed change wear
Add feed and retract switches and emergency stop switches at the rear of the machine tool for easy operation and adjustment.
