As an efficient equipment in the field of precision machining, the core advantage of the dual head carving machine lies in its composite processing capability of "dual spindle synchronous linkage+multi process integration", which relies on the deep collaboration of multiple systems. This collaboration is not simply dual axis parallel, but rather the adaptation of structure, motion, control, and process to jointly ensure the dual improvement of machining accuracy and efficiency.
Structural collaboration is the fundamental support for collaborative processing. The equipment adopts a symmetrical dual spindle layout, and the center distance between the two spindles can be accurately adjusted according to the size of the workpiece. The integrated bed design ensures rigidity consistency and avoids collaborative deviation caused by structural deformation during processing. The spindle unit is equipped with high-precision electric spindles of the same model to ensure synchronous speed and power output of the two axes. At the same time, the tool magazine system adopts a shared layout, which realizes the coordinated switching of two spindle tools through an automatic tool changing mechanism, reducing tool changing time and ensuring the matching of tool specifications, laying a structural foundation for multi process composite machining.
Motion collaboration is the core execution logic of collaborative processing. Based on a multi axis linkage control system, the two main axes can achieve two core motion modes: "synchronous on track" and "synchronous off track". In synchronous and same track mode, the two main axes run at the same trajectory and speed, which can perform mirror machining on symmetrical workpieces or double tool synchronous cutting on a single workpiece, improving machining efficiency; In synchronous cross track mode, the system allocates two axis motion paths through trajectory planning algorithms to achieve multi process parallelism. For example, when one axis performs rough machining, the other axis synchronously completes precision machining, or performs different processes such as drilling and milling separately, greatly reducing the machining cycle. In motion coordination, the high rigidity of the guide rail and the high-precision driving of the linear motor ensure that the motion error of the two axes is controlled at the micrometer level.
Control collaboration is the intelligent center of collaborative processing. Adopting a distributed control system architecture, the main controller coordinates the execution units of the two spindles, tool magazine, workbench, etc., and achieves information exchange between each module through a real-time data bus. The system has a built-in collaborative control algorithm that can dynamically distribute the load between the two spindles, avoiding accuracy fluctuations caused by uneven load during machining; Simultaneously integrating the calibration function of the workpiece coordinate system, precise alignment of the two spindle coordinate systems is achieved through laser probes, eliminating benchmark deviations. In addition, the fault diagnosis module can monitor the real-time operation status of both axes, and immediately trigger collaborative shutdown in case of any abnormalities, ensuring machining safety.
Process collaboration is the guarantee for the value implementation of collaborative processing. According to the processing requirements of the workpiece, the system can preset collaborative process plans, such as planning the process of "dual axis synchronous rough milling → alternating precision milling → synchronous polishing" for complex curved workpieces; For small batch workpieces, parallel processing can be achieved by clamping different workpieces with two axes. In process collaboration, the optimization algorithm of tool path can avoid interference between two axes, and ensure the consistency of surface quality of two axis machining through collaborative matching of cutting parameters.
In summary, the collaborative principle of the dual head carving machine is the organic integration of structure, motion, control, and process. Through precise adaptation of each system, it achieves a processing efficiency of "1+1>2", providing efficient solutions for precision manufacturing.
