The '1325' designation refers to a working area of 1300mm x 2500mm, which is the industry standard for processing full-sized 4x8 feet sheets. Key specs include Spindle Power (typically 3.0kW to 9.0kW), Drive Systems (Stepper motors for economy or Leadshine/Yaskawa Servo motors for high precision), and Control Systems (such as DSP, Mach3, or NC-Studio). Ensure the machine uses a heavy-duty seamless welded steel structure that has undergone high-temperature tempering to prevent deformation over time.
