In the processing fields of ultra-large-sized workpieces such as turbine rotor, ship propeller shaft, and core components of energy equipment, "large size, heavy load, and high precision" have always been recognized as the technical difficulties in the industry. And the TK6926*236 CNC boring and milling machine under the leadership of xiangyu baoyuan is precisely the "heavy-duty" equipment that overcomes these difficulties. This equipment is not a commercial product for sale to the outside world; instead, it is the powerful symbol of xiangyu baoyuan's deep commitment to heavy processing. Every parameter and every design of this equipment tells the strong confidence of the enterprise in undertaking the processing of ultra-large-sized workpieces.
The ability to handle the heavy task of processing super-large workpieces stems primarily from the "giant-sized" basic configuration of TK6926*236. Its processing range directly covers the super-large size range of 23 meters in length and 6 meters in height. Combined with a 5-meter by 5-meter ultra-wide worktable and a 180-ton powerful rotating platform load-bearing capacity, it can ensure that heavy machinery components weighing tens of tons, as well as ship transmission shafts up to twenty meters in length, can all be securely "settled" here for all-round boring, milling, and drilling integrated processing. Currently, xiangyu baoyuan has equipped one of this type of equipment. Just with this "single champion", it is sufficient to break the reliance on outsourcing for processing super-large workpieces, firmly control the core processing stage， and provide customers with a full-process closed-loop service from raw materials to finished products.
If the super-large size is the "external framework" of it, then the six core technical features are its "inner soul", and they are also the core support of Xiangyu Baoyuan's processing strength. In terms of precision control, this equipment can be called a "detail-oriented" one - the closed-loop constant-flow static pressure guide rail design makes the equipment run as stable as a rock, with both seismic resistance and precision retention fully achieved; combined with the full closed-loop control system, German imported optical encoders, and dual-motor drive technology, it precisely eliminates transmission gaps, and even for complex curved surface processing, it can achieve consistent dimensions with millimeter-level accuracy, which is precisely the confidence of Xiangyu Baoyuan in its "zero tolerance" for processing quality.
In terms of processing efficiency, it is truly a versatile "multi-functional" device. It supports seven-axis control and arbitrary five-axis linkage, enabling multiple processes such as drilling, reaming, boring, slotting, plane and curved surface milling, without the need for frequent machine changes or piece flipping. All these can be completed in one go. After installing accessories like rotating worktables or right-angle milling heads, it can also achieve five-dimensional processing, completely eliminating the inefficient mode in traditional processing where "the workpiece follows the equipment around". For extremely large and complex parts, this comprehensive processing capability not only significantly shortens the processing cycle but also reduces errors caused by multiple clamping, achieving a double improvement in delivery efficiency and processing accuracy.
Facing the rigorous challenges of heavy-duty cutting, its "tough guy" characteristics are equally impressive. The base components such as the column, bed, and slide rest are all made of high-quality cast iron, and undergo aging treatment to completely eliminate internal stress. The overall rigidity is far superior to that of ordinary equipment. The dual hydraulic cylinder proportional valve compensation system of the slide rest, combined with the dual-motor, dual-screw, and dual-gauge ruler joint compensation technology of the spindle box, can ensure stable operation without vibration even under high-intensity heavy-duty cutting conditions. This perfectly meets the high-strength processing requirements for ultra-large workpieces, which also demonstrates the hard power of xiangyu baoyuan in undertaking difficult heavy-duty processing orders.
Behind the stable operation lies the strong support of imported core components. Key electrical components such as the spindle drive unit and the feed drive unit use original components from internationally renowned brands like Siemens or Fanuc; the hydraulic system integrates the constant-flow multi-head pump from German VOGEL Company to precisely supply oil to the static pressure guide rail, further enhancing the seismic resistance. These high-end configurations ensure that the equipment remains stable and reliable during long-term high-intensity operation, fundamentally guaranteeing the continuity and stability of the processing process. This is also the core guarantee for xiangyu baoyuan to provide reliable processing services to customers.
What's even more remarkable is that it also possesses extremely strong "adaptability" and "flexibility". The modular design enables it to flexibly add or remove functions such as automatic tool changing units and extended slide carriers according to the needs of different industries, easily adapting to core component processing scenarios in fields such as steam turbines, heavy-duty motors, ships, and energy. The user-friendly operation design and comprehensive safety protection also make the "giant" have a "gentle heart" - the centralized operation button station that can be raised and lowered with the main spindle box, and the convenient handheld operation unit, significantly reducing the difficulty for operators in debugging; the fully enclosed CNC rotating worktable guard not only prevents chips and coolant from entering to extend the equipment's lifespan, but also provides comprehensive safety protection for operators, fully demonstrating the production philosophy of "efficiency and safety both emphasized" of xiangyu baoyuan.
A TK6926*236 CNC boring and milling machine is a vivid illustration of Xiangyu Baoyuan's processing capabilities. It not only overcomes the size and weight limitations of ultra-large workpieces, but also provides a solid foundation for the manufacturing of core components in multiple key industries with its high precision, high efficiency, and high stability processing capabilities. For Xiangyu Baoyuan, this machine is not a product for sale, but a core competitiveness carrier that serves customers and stands firm in the industry. In the future, Xiangyu Baoyuan will continue to rely on this "guardian of the seas" type of high-end equipment, with more exquisite processing technology and more reliable delivery capabilities, to solve the problems of processing ultra-large workpieces for customers in various industries, demonstrating the enterprise responsibility and technical style of Chinese heavy processing in this field.
