The CATO CBS300 Five-Axis Gantry Type Machining Center is an excellent solution for blisk machining. Addressing the pain points of blisk machining such as narrow processing space, strict precision requirements, easy deformation, and high difficulty in tool connection, the equipment relies on its bridge-type high-rigidity structure, direct drive technology, independently developed electric spindle, and diversified system configurations to achieve micron-level precision and tool connection accuracy within 0.01mm. With outstanding core parameters, it can complete machining in only 21 hours, balancing quality and efficiency, and is suitable for high-end needs in the military industry.
As a core component with large usage and high technical requirements in the aviation industry, blisk machining faces multiple challenges such as narrow processing space, strict precision requirements, easy deformation, and high difficulty in tool connection. To efficiently overcome these problems, it is crucial to select a high-performance machining center with strong adaptability. CATO Precision Machinery (Guangdong) Co., LTD's CBS Five-Axis Gantry Type Machining Center CBS300 has become an exclusive solution for blisk machining, relying on advantages such as structural innovation and independent core technologies.
Supported by a Rigid Structure: Solving Narrow Space and High Rigidity Requirements
The narrow processing space of blisks places extremely high demands on the structural stability and rigidity of the machine tool. The CBS300 Five-Axis Gantry Type Machining Center adopts a gantry-type high-rigidity structural design, featuring a stable overall structure that can withstand large workloads. Even during high acceleration and deceleration movements of the X,Y,Z Axis, it is completely unaffected by the size and weight of the workpiece, providing solid support for precise cutting in narrow spaces. Equipped with high-rigidity roller guideway, it further enhances the machine tool's rigidity, effectively suppressing cutting vibrations and avoiding machining errors caused by insufficient rigidity, perfectly adapting to the processing needs of special tools for blisks.
Empowered by Direct Drive Technology: Building a Micron-Level Precision Defense Line
Blisks require a contour accuracy of ≤ 0.05mm and a tool connection accuracy within 0.01mm after secondary clamping, which is a severe test for the dynamic performance and positioning accuracy of the machine tool. The CBS300 Five-Axis Gantry Type Machining Center has made breakthroughs in drive technology: the X and Y axis are directly driven by high-performance linear motors, paired with a high-precision linear scale and circular scale feedback system. This eliminates mechanical transmission backlash, achieving high acceleration/deceleration response and micron-level positioning accuracy—with a positioning accuracy of 0.005mm and a repeatability of 0.003mm, accurately meeting the contour accuracy requirements.
The A , C axis are equipped with CATO's independently developed five-axis cradle, directly driven by torque motors. The absence of mechanical transmission ensures no backlash or wear, enabling long-term maintenance of high precision and low noise during high acceleration/deceleration movements. Combined with high-precision encoders, it achieves precise positioning and control during the machining process, greatly reducing secondary clamping errors and easily achieving tool connection accuracy within 0.01mm, ensuring a smooth and traceless surface of the machined blisk. Meanwhile, the synergy of high rigidity and high precision effectively controls the deformation of thin blades during machining, guaranteeing the forming quality of the parts.
Independent Spindle Core: Ensuring High-Speed and Stable Machining
As the "power core" of the machining center, the spindle directly affects the machining accuracy and efficiency of blisks. The CBS300 Five-Axis Gantry Type Machining Center is equipped with a self-developed HSK-E40 built-in electric spindle. Through forced cooling technology, it precisely controls the temperature of the motor and front/rear bearings, effectively eliminating runout and vibration during long-term high-speed machining and maintaining stable precision. The spindle features high rigidity, high speed, high power, and high torque—its power (S1/S6 40%) reaches 11/16.5KW, and torque (S1/S6 40%) reaches 10.3/15.45NM, which can efficiently meet the cutting needs of blisk machining.
More reliably, CATO masters the core technologies of spindle design, manufacturing, and assembly, adopting refined modular production in a constant temperature and humidity workshop to ensure high spindle reliability, providing continuous power support for the continuous and efficient machining of blisks.
Diversified System Configuration: Adapting to Flexible Production Needs
To meet the operating habits and production scenarios of different users, the CBS300 Five-Axis Gantry Type Machining Center offers flexible control system options: the standard configuration includes the Siemens Sinumerik One system, ensuring machining stability and compatibility; optional configurations include the Heidenhain TNC640 system and CATO's independently developed C80 Plus system, adapting to high-end intelligent machining and localized operation needs. Meanwhile, the machine tool is equipped with 25 tools, the X, Y , Z axis feed rate reaches 48m/min, and the axis travel of 300×350×250mm and the Φ300mm working table can fully cover the machining sizes of mainstream blisks, greatly improving production efficiency.
