7. Combined Vacuum Table and T-Slot Table
   • Vacuum Table with Rubber Sealing Ring:
     • The vacuum table holds the workpiece securely through suction, which saves labor and time compared to manual clamping methods.
     • The rubber sealing ring ensures an airtight seal, optimizing the vacuum pressure for better material fixation.
     • Vacuum Zones: The table is divided into multiple zones, each of which can be independently activated or deactivated with a switch. This allows for targeted clamping, saving energy and reducing unnecessary suction.
       
   • Liquid Ring Vacuum Pump:
     • The vacuum system is powered by a 5.5kW Liquid Ring Vacuum Pump, which operates at a 33 MBar pressure and delivers an airflow of 230 m³/h. This high-performance pump provides strong, reliable suction to hold the workpieces firmly during machining.
   • Table Surface:
     • The vacuum table is constructed from PVC grey plates, offering a durable and easy-to-maintain surface for a wide range of materials.
     • The table’s pattern is machined by the CNC wood router itself once the table is installed, ensuring a uniform working surface that allows for precise clamping.
     • The CNC machining of the surface provides a replaceable surface design, allowing for easy maintenance or updates as needed.
   • Combined T-Slot Table:
     • In addition to the vacuum system, the table features a T-slot surface that allows for additional clamping methods, giving users the flexibility to choose the best workholding method for the job.
     • The combination of vacuum and clamping allows for optimal material fixation, reducing the time spent securing workpieces.
8. Dust Collector System
   • Dust Collection and Exhaust Control:
     • Both cutting and carving processes generate significant dust and debris. Our Dust Collection System uses a combination of a dust hood on the spindle and a vacuum mechanism to capture and manage this dust.
     • The dust residue is vacuumed away directly into the dust collector's dust bag, preventing it from scattering into the work environment. This system significantly reduces airborne dust and keeps the work area cleaner.
   • Cleaner Working Environment:
     • The dust collection system ensures a cleaner workspace, reducing the accumulation of dust particles that can affect the quality of the work and the health of the workers.
     • With effective dust management, the system helps maintain a healthier workforce, reducing respiratory risks and enhancing comfort for operators.
   • Increased Lifespan of Machine Parts:
     • By capturing dust and preventing it from entering the machine's mechanical parts, the dust collection system helps extend the lifespan of critical components, such as motors and bearings, by keeping them clean and free from abrasive particles.
   • Blower Motor Specifications:
     • Blower Motor Power: 3KW, ensuring sufficient suction power to manage large amounts of dust.
     • Air Intake: 2300 m³/hour, providing strong airflow to effectively capture dust and particles from the cutting area.

     • A dust hood is provided with each CNC wood router to cover the spindle area. This hood connects to the dust collection system, ensuring efficient dust suction during operation.
     • The dust hood can also be connected to your own dust collection system, allowing for easy integration if preferred.
   • Dust Hose:
     • A soft dust hose with a diameter of 100mm and a length of 4 meters or longer is included when purchasing the dust collector. This hose connects the machine to the dust collection unit, ensuring proper dust extraction during the cutting or carving process.
9. Rotary Axis Design
   • Position and Placement:
     • The rotary axis is strategically positioned on the side of the CNC router, which does not interfere with the main worktable used for flat material processing. This layout allows for dual-purpose usage, where the router can work on both flat and cylindrical materials without additional setup time or space limitations.
     
     
   • Maximum Processing Diameter:
     • The rotary axis supports processing of materials with a maximum diameter of 300mm. This allows for the efficient and accurate engraving and cutting of cylindrical or round-shaped workpieces, such as wood logs, metal rods, or pipes.
   • Maximum Length:
     • The rotary axis accommodates materials with a maximum length of 3000mm, enabling the machine to handle long, continuous workpieces, ideal for a variety of projects including large-scale sculptures, signage, or other custom 3D carvings.
   • Precision and Stability:
     • The rotary axis is equipped with a four-jaw chuck and center support to ensure high stability and accuracy during rotation. The center support prevents material deflection, ensuring that the workpiece remains steady throughout the engraving or cutting process.
       
       
     • The four-jaw chuck provides a secure grip on the material, ensuring uniform rotation and preventing slippage during machining. This design ensures consistent precision even on large or irregularly shaped workpieces.
       
   • Enables 3D Processing:
     • Unlike traditional systems that simply add a fourth axis to the existing three-axis setup (often only mapping flat designs onto cylindrical shapes), this rotary axis system supports full four-axis motion. 4 Axis Rotary CNC Router with DSP A18 Controller for 3D Cutting and Engraving allows for complex 3D engraving, deep carving, and even hollowing or undercutting, which is not possible with a simple three-axis plus one setup.
     • The system’s ability to move in all directions (X, Y, Z, and rotation) gives it full freedom for complex 3D designs, creating deeper, more intricate details that add significant value to the final product.
   • Design for Stability and Flexibility:
     • The rotary axis design is optimized for precision machining of both hard and soft materials such as wood, plastic, and certain metals. It is engineered to be highly stable even under extended use, ensuring long-term reliability.
     • The ability to rotate the material allows users to engage in multi-axis cutting, providing greater flexibility in project designs.
   • Ease of Integration:
     • The rotary axis integrates seamlessly into the machine’s mainframe and can be operated independently or simultaneously with the other axes for fully coordinated movement. It is controlled by the same DSP A18 controller that drives the rest of the machine, allowing for smooth operation and user-friendly programming.
10. Rotary Alternative Configurations
    • Rotary Axis Positioned at the Front:
      • The rotary axis can be placed at the front of the machine, reducing the overall machine size and footprint. This configuration is ideal for environments where space is limited but full four-axis functionality is still required. By placing the rotary axis at the front, the machine can maintain its compact design, enabling efficient operations without compromising on capabilities.
        
      Advantages:
      • Space-saving: This setup allows for a more compact machine design, ideal for workshops with limited space.
      • Easy access: With the rotary axis at the front, the operator has easy access to both the table and the rotating parts, simplifying loading and unloading of materials.
    • Rotary Axis on the Machine Bed (Removable):
      • Another flexible option is to mount the rotary axis directly on the machine bed, making it removable when not in use. This option allows the operator to convert the machine from a three-axis router to a four-axis router as needed, providing versatility for different types of projects.
      Advantages:
      • Modular Design: The removable rotary axis provides the flexibility to use the machine for both flat and cylindrical material processing, based on specific project needs.
      • Convenient Storage: When not required for a particular job, the rotary axis can be easily removed and stored, ensuring the machine's table remains free for flat material processing.
      • Customizable Space Usage: With the rotary axis off the bed, the machine can be used for standard cutting and engraving without taking up additional space, making it adaptable to various workshop requirements.
