Features:
◆ Adopts a 45-degree inclined integral frame bed, which has good rigidity and is easy to remove chips;
◆ Simultaneous processing of both ends with one clamping, high processing efficiency and good precision;
◆ Equipped with a double spindle structure, which can be used for single spindle processing (short workpieces) and double spindle processing (long workpieces);
◆ The position of the auxiliary spindle is controlled by programming and can be adjusted freely according to the length of the workpiece;
◆ The extra-large stroke elastic chuck has strong adaptability to the blank and can easily clamp workpieces with large ends and small middle;
◆ Separate chuck design, the workpiece can be processed in the full range by replacing the chuck, without replacing the elastic chuck;
◆ The spindle has high rotation precision, good rigidity, and is driven by a high-speed, high-torque servo spindle motor;
◆ Left and right independent tool turrets, servo tool turrets or power tool turrets can be selected separately;
◆ The extra-large stroke design of the auxiliary spindle can clamp long workpieces in the middle of the two spindles, reducing the floor space of the machine tool;
◆ Equipped with an automatic lifting auxiliary clamping system, which can realize automatic workpiece clamping;
◆ Dual-channel CNC system, both sides can process synchronously or process different content;
◆ Fully enclosed internal and external protection, automatic lubrication, cooling and chip removal;
