Cnc 7 axis

Types of CNC 7 Axes

CNC machine tools with seven axes are complex and versatile systems. Their main distinction lies in the type of CNC controllers and the applications for which they are designed. Here are some common types of 7-axis CNCs:

• CNC 7 Axis Laser: A laser-cutting machine with seven axes can achieve complex cuts with high precision. The additional axial typically rotates the workpiece to facilitate better access to the material for the laser beam, improving cutting quality and efficiency. For example, a CNC machine with both rotary and tilt motion can perform a wide range of cutting tasks, such as engraving, cutting, and welding at various angles.
• CNC 7 Axis Router: This machine is found primarily in the woodworking industry, such as furniture and musical instrument manufacturing. Woodworkers can use it to carve, design, and cut wood into different shapes and patterns precisely. The router typically has a vertical spindle that can be changed to accommodate different tools for various operations.
• CNC 7 Axis Mill: Similar to the router but for metal materials, a milling CNC machine (also called a 7-axis CNC lathe) works precisely on metals. It allows for more complex operations, including drilling and boring, due to its increased degrees of freedom. With the additional seven axes, technicians can perform intricate machining tasks such as milling, drilling, tapping, and slotting with high precision and automation.
• 7 Axis Multitasking CNC Machine: These machines combine milling and turning functions into a single setup. They offer high-speed machining, live tooling, and off-center milling capabilities. The seven-axis configuration enables productive and precise machining of complex parts with integrated automation.

Maintenance

• Regular Check: User manuals usually provide specific instructions on checks. In general, refer to the manual to check for loose components and ensure gears and chains' tightness and alignment. Inspect and quickly replace damaged or worn tools for optimal cutting effectiveness; adjust the height, angle, and position of the tool rest according to different materials and processing requirements to achieve the best use effect.
• Lubrication: Provide sufficient and appropriate lubrication according to the recommended lubricant type and quantity in the manual. Frequently oil the axes, rails, and gears, as well as the active bearings and sliding parts of the tool holder and feed system. Use lubricants with anti-oxidation and moisture-proof properties, such as anti-oxidation and high-temperature food-grade lubricants for aluminium lubricants.
• Dust Removal: For air-cooled spindles, regularly replace the cooling fan if the machine is not used for a long time to avoid damaging the bearing. Fans used for dust removal should be explosion-proof to prevent ignition hazards. Clean the dust on the rails and guide rods of the CNC machine, removing the dust on the strip in time to prevent the garbage from damaging the circuit. Meanwhile, keeping the work surface clean and free of obstacles can help prevent hidden dangers and improve processing quality.
• Hardware Maintenance: Ensure electrical parts in the control box, such as electrical connections and contact elements, are clean and free of oxidation. Prevent static electricity, dust, and moisture from entering the control system. Replace the belts and synchronization chains to ensure that the gears and belts are properly tensioned.
• Calibration: Periodically calibrate the machine's axes to ensure position accuracy. Regularly adjust the machine's level and square to ensure stable operation and processing precision. Referring to the specific leveling and squaring methods in the manual to improve its use and service life. Before major repairs, take appropriate safety measures and disconnect the power supply. If necessary, consult a professional for advice on specific operations and maintain the machine's stability and processing precision for a long time.
