    Product Description

    CNC Turning and Milling Machine Overview
    • GSK CNC Control System
      GSK CNC Control System
      The machine is equipped with a GSK CNC control system, a high-performance and reliable numerical control unit widely used in precision machining. The GSK system supports multi-axis interpolation, high-speed processing, and advanced programming capabilities, including ISO-standard G-code and user-friendly conversational programming. Its intuitive touchscreen interface allows for easy operation, real-time monitoring, and quick parameter adjustments. The system also features built-in diagnostic tools, error detection, and customizable macros to optimize complex machining tasks. With stable performance and compatibility with various machine configurations, the GSK CNC ensures high accuracy and productivity.
    • Hydraulic Clamping with Collet
      Hydraulic Clamping with Collet
      The machine incorporates a hydraulic clamping system for secure and efficient workpiece holding. The collet chuck provides strong gripping force and excellent concentricity, ensuring minimal runout during high-speed operations. The hydraulic mechanism enables fast and consistent clamping, reducing setup time and improving workflow efficiency. The hydraulic system is designed for durability, with adjustable pressure settings to accommodate different materials and machining requirements.
    • 12-Station Power Tool Turret
      12-Station Power Tool Turret with Optional Y-Axis
      A 12-station power tool turret is integrated for automatic tool changes, significantly reducing downtime in multi-operation machining. Each station can hold various cutting tools (e.g., drills, taps, end mills), allowing complex parts to be completed in a single setup. The turret is optionally equipped with a Y-axis, expanding machining capabilities for off-center operations, contouring, and milling tasks. This flexibility makes the machine suitable for intricate components that require both turning and milling operations. The turret’s robust design ensures quick indexing and high repeatability for precision machining.
    • Screw Lead and Linear Guide Rail
      Screw Lead and Linear Guide Rail
      The machine utilizes precision ball screw leads for accurate motion transmission in the X, Y, and Z axes, minimizing backlash and ensuring smooth movement. Combined with high-rigidity linear guide rails, this setup provides excellent stability, reduced friction, and long-term wear resistance. The linear guides enhance dynamic performance, allowing high-speed machining while maintaining tight tolerances (±0.005mm or better). This combination is ideal for applications requiring repeatability, fine surface finishes, and heavy-duty cutting operations.
    • Spindle with Servo Motor
      Spindle with Servo Motor
      The machine features a high-performance spindle driven by a servo motor, ensuring precise speed control, high torque, and rapid acceleration. Unlike traditional belt-driven spindles, the servo motor provides direct power transmission, reducing energy loss and improving efficiency. The spindle supports a wide speed range (adjustable via CNC programming) and is equipped with automatic tool clamping and cooling systems to maintain thermal stability during prolonged use. This setup is ideal for both heavy-duty machining and high-speed finishing operations.
    • Separated Electric Distribution Cabinet
      Separated Electric Distribution Cabinet
      The machine includes a separated electrical cabinet, isolating sensitive control components from heat, dust, and vibrations generated during machining. This design enhances system reliability and extends the lifespan of electrical parts. The cabinet features efficient cooling (fans or air conditioning) to prevent overheating and ensure stable operation. Additionally, the separation allows for easier maintenance and troubleshooting, as all wiring, PLCs, and servo drives are neatly organized and accessible.
