This utility model relates to a dual-turret vertical turning composite machine tool. It solves the technical problems of insufficient support for the workpiece in existing spindle systems. It includes a machine tool base and a machine tool column vertically mounted on the upper part of the machine tool base. Two power turrets are movably mounted on one side of the machine tool column, and a turret movement drive mechanism is provided between the power turrets and the machine tool column. The power turrets have at least one of turning, milling, and drilling / milling components. An electric spindle is located on the upper part of the machine tool base, with a chuck assembly for clamping the workpiece at its upper end and a brake assembly. A spindle-type center assembly is located on one side of the machine tool column via a tailstock vertical lifting structure. The advantages are: the design of the electric spindle and chuck assembly, the pull-back chuck connected to the rotary cylinder via a pull rod, provides uniform and stable clamping force, enabling high-speed cutting and precision machining; and the spindle-type center assembly, with its height adjustable via the tailstock vertical lifting structure, forms end support with the chuck assembly.

The invention relates to the technical field of edible mushroom production equipment, and discloses an automatic bag cultivation pilose antler mushroom cutting machine which comprises a rack, a main conveying line is installed at an inlet of the front face of the rack, a belt conveying unit installed in the rack is arranged above the main conveying line, and the belt conveying unit extends to the outer side of the rack from the side face of the rack; a band saw cutting mechanism is arranged on the side, located in the rack, of the belt conveying unit and located over the main conveying line. By arranging the main conveying line and the belt output unit and arranging the band saw cutting mechanism at the space intersection of the main conveying line and the belt output unit, automatic cutting of the bag-cultivated velvet antler mushrooms can be achieved, cutting-off and transferring of the bag-cultivated velvet antler mushrooms can also be achieved, the harvesting efficiency of the bag-cultivated velvet antler mushrooms is greatly improved, the labor intensity of workers is reduced, and the labor intensity of workers is reduced. Meanwhile, the contact between a human body and a cutting tool can be reduced, and the safety of production operation is improved.

A band saw machine (91) includes a first wheel (31) that applies tension to a band saw blade (5) to track the band saw blade (5), a second wheel (32) disposed below the first wheel (31), a first supply portion (71) disposed between a lowermost end (P6) of the second wheel (32) traveling toward the first wheel (31) from the second wheel (32) in a rotational travel path of the band saw blade (5) to a workpiece cutting position (P1) to spray a cutting fluid (L) of mist (L1) to a tooth portion (5b) of the band saw blade (5) or to drip the cutting fluid (L), and a second supply portion (72) disposed between the workpiece cutting position (P1) and the second wheel (32) to spray or spray the cutting fluid (L) or a cooling fluid to the band saw blade (5).
