The configuration of the spindle, lead screw and guide rail of the CNC tool placement machine directly affects the processing accuracy, efficiency and stability. The following is an introduction from three aspects: key points of configuration, configuration plan and maintenance suggestions
Key points of configuration
Youdaoplaceholder0 main shaft :
Youdaoplaceholder0 Speed range : The spindle speed range of the economical tool placement machine is 50-3000r/min, and that of the medium and high-end models is 50-5000r/min or higher. The high-speed spindle is suitable for precision machining.
Youdaoplaceholder0 power : The power of the economical spindle is 3-7.5kW, and that of the medium and high-end ones is 11-22kW. The high-power spindle can process hard materials.
Youdaoplaceholder0 rigidity : The rigidity of the spindle affects the cutting stability. A high-rigidity spindle can reduce vibration and improve surface quality.
Youdaoplaceholder0 lead screw :
Youdaoplaceholder0 type : Ball screw transmission efficiency is high (>90%), suitable for high-speed and high-precision processing; Trapezoidal lead screws have low efficiency (20-30%) and are suitable for low-speed and heavy-load processing.
Youdaoplaceholder0 lead : A large lead (such as 10mm) is suitable for high-speed machining, while a small lead (such as 5mm) is suitable for precision machining.
Youdaoplaceholder0 Precision grade : Lead screws of P5 grade and above are used in high-precision CNC machine tools, while those of P7 and P10 grades are used in general machinery.
Youdaoplaceholder0 guide rails :
Type : Rolling guides (linear guides) have a low coefficient of friction and a fast response speed, making them suitable for high-precision and high-speed processing. Sliding guide rails (hard rails) have good rigidity and strong load-bearing capacity, making them suitable for heavy cutting.
Youdaoplaceholder0 Precision grade : Guide rails of grade P and above are used in high-precision CNC machine tools, while those of grade H and below are used in woodworking machinery, industrial robots, etc.
Youdaoplaceholder0 Preloading grade : High preloading reduces backlash but increases friction torque. The selection should be based on processing requirements.
Configuration plan
Youdaoplaceholder0 economy configuration :
Spindle : rotational speed 50-3000r/min, power 3-7.5kW, suitable for processing small and soft parts.
Youdaoplaceholder0 lead screw : trapezoidal lead screw, lead 5-10mm, precision P7-P10 grade, low cost, suitable for low-speed and heavy-load processing.
Youdaoplaceholder0 guide rail : Sliding guide rail, with precision below H grade, good rigidity, suitable for heavy cutting.
Youdaoplaceholder0 mid-to-high-end configuration :
Spindle : rotational speed 50-5000r/min or higher, power 11-22kW, suitable for processing large and hard parts.
Youdaoplaceholder0 lead screw : Ball screw, lead 10-20mm, precision above P5 grade, high transmission efficiency, suitable for high-speed and high-precision processing.
Youdaoplaceholder0 guide rail : Rolling guide rail, with precision above P grade, low friction coefficient, fast response speed, suitable for high-precision and high-speed processing.
Youdaoplaceholder0 high-end custom configuration :
Spindle : high-speed electric spindle, with a rotational speed of over 10,000 r/min and a power of over 22kW, suitable for ultra-precision machining.
Youdaoplaceholder0 lead screw : High-precision ball screw, adjustable lead, accuracy of P0-P1 grade, suitable for ultra-precision positioning.
Youdaoplaceholder0 guide rails : hydrostatic guide rails with an extremely low coefficient of friction and ultra-high precision (UP), suitable for ultra-precision processing.
Maintenance suggestions
Youdaoplaceholder0 Regular lubrication : Use the specified lithium-based grease, avoid mixed greases, and reduce wear.
Youdaoplaceholder0 Dust-proof measures : Install telescopic protective covers, regularly clean track debris to prevent guide rail wear.
Youdaoplaceholder0 Abnormal detection : Listen for abnormal sounds, monitor temperature rise (shut down for inspection if the temperature exceeds 60℃), and promptly identify faults.
