Background of the project
A domestic machine tool equipment manufacturer produces advanced coiled wire lathe products to meet the needs of the domestic market for high-grade CNC lathes for large-scale chuck coils. The lathe is equipped with a multi-station turret with a tool post that can not only be turned. Chuck end face coil thread and other kinds of inner and outer cylindrical surface, conical surface, circular arc surface, male and female thread, etc. It can also process axial, radial drilling, reaming, boring and tapping of metal products. It is an ideal full-function lathe.
Delta provides a new CNC lathe NC200 series for this type of machine tool, adopting cost-effective embedded hardware design, using Delta's dedicated servo series, spindle motor, and new generation communication network DMCNET for high-speed data transmission and control to meet high speeds. , High-precision machining purposes. System control shown in Figure 1.

Project proposals
The machine's rigidity, dynamic and static stiffness, mechanical structure of the main components, protection, cooling, etc. are all designed according to the modern optimization concept, with high rigidity, high precision, excellent precision retention and high production efficiency, etc. CNC lathe CNC system NC200 series operation is very user-friendly, coupled with friendly interface design, easier to use.
NC200 series is Delta's demanding feature for turning machining. It introduces a high-performance CNC system. It uses high-performance embedded hardware design, together with Delta dedicated servo, spindle motor and new generation communication network DMCNET for high-speed data transmission and control. Satisfy the purpose of high-speed, high-precision metal cutting.
The main highlight of the NC200 series is that, while completing the lathe processing task, it can also complete the rotation and tool changing of the multi-station turret, so that the production and processing can be performed continuously and the machining efficiency of the machine tool can be improved.
In coiled wire lathes, the vertical multi-station electric turret uses worm gear rotation, and the tri-gear occlusal screw lock works. The turret part is controlled by a three-phase asynchronous motor. According to the system requirements, the NC200 series is connected with high-speed communication sports. Control network (DADA CNC servo drive ASDA-A2-NN and servo motor), through the detection of the sender on the top of the carrier plate, the high-speed serial IO control solenoid valve switching control commutation, and through the delay relay lock Tight end. The turret work flow is shown in Figure 2.
