FANUC-Powered AT-361MY CNC Machine with Hard Track Technology

Introduction to AT-361MY CNC Lathe
    The AT-361MY CNC lathe is an industrial-grade machining equipment that combines high-precision processing with multi-functional adaptability. Designed specifically for efficient cutting of medium and large workpieces, it is widely applicable to mass production and precision machining scenarios in automotive parts, mechanical components, hardware accessories and other fields.
     The core configuration of the equipment is equipped with a TCSM model power turret, adopting BMT55-12T turret specifications (12 tool stations), which can quickly switch between different processing tools to meet composite processing needs such as drilling, milling, and turning. Combined with a 3.7KW power tool motor, it provides stable power output for various metal cutting processes. The control system uses the industry-proven FANUC 0I-TF system, featuring a user-friendly interface and fast response, which can accurately control processing parameters and ensure the machining accuracy of complex procedures.
       In terms of processing capabilities, the AT-361MY performs outstandingly: the maximum swing diameter of the bed reaches 700mm, and the maximum machining diameter is 380mm, which can accommodate larger-sized workpieces; the Z-axis processing length is 1100mm, combined with a bar processing diameter of 75(92)mm, which can cover the processing needs of various workpieces such as long shafts and discs. Each axis has excellent motion performance: the X-axis stroke is 230mm, the Y-axis stroke is 100mm, both driven by 3.0KW servo motors, combined with R32/10 (X/Y axis) and R40/10 (Z axis) ball screws, the running speed can reach 15-20m/min, and the repeat positioning accuracy reaches X-axis 0.003mm, Y-axis 0.005mm, Z-axis 0.007mm respectively, ensuring the dimensional consistency and surface finish of processed workpieces.
     As the core power source of the equipment, the spindle system adopts A2-8 type spindle nose with a through hole diameter of 92(106)mm, combined with NN3026(3028) type bearings (bearing diameter 130(140)mm), supporting a spindle speed of 3000(2500)rpm. The 11-15KW (Guangyu) spindle motor can flexibly adjust the output power according to the processing material (such as steel, aluminum, alloy, etc.), balancing high-speed cutting efficiency and low-speed heavy-load stability. The equipment is also equipped with a programmable tailstock with a tailstock mandrel outer diameter of 80mm and a taper of MT5, which can provide reliable support for long workpiece processing, reduce workpiece vibration, and further improve processing accuracy.
    In terms of structural design and practicality, the AT-361MY adopts a high-rigidity bed. The X, Y, and Z axes are all configured with hard tracks, which have strong wear resistance and high load-bearing capacity, and can maintain stable processing accuracy after long-term use; the 300-liter large-capacity water tank can effectively meet the cooling needs of long-term processing and avoid tool overheating affecting processing quality; the total weight of the equipment is 6400kg, with a floor area of 355×177cm, featuring a stable structure and reasonable layout, suitable for installation and production planning in most industrial workshops. The packaging size of 400×230×228cm also facilitates long-distance transportation and workshop deployment.
     Overall, with its precise control performance, strong processing capability and reliable structural design, the AT-361MY CNC lathe can not only meet the refined processing of small and medium batch precision parts but also cope with the efficiency requirements of mass production, making it a cost-effective composite processing equipment in the field of industrial manufacturing.
