The core principle of the automatic feeding vibration table for CNC lathes is that it drives the parts to climb orderly along the spiral track and output them in a targeted manner through electromagnetic vibration. Its working process can be decomposed into the following key steps:
I. Power Source: Electromagnetic Vibration System

Pulse Electromagnet: Installed at the bottom of the hopper, it generates a periodically changing magnetic field when powered on.
Spring Plate Assembly: Inclined elastic elements installed, cooperating with the electromagnet to form a resonance system. When the electromagnet attracts, the spring plates deform to store energy; when released, the spring plates return to their original shape and release energy, driving the hopper to produce high-frequency and small-amplitude vibration.
II. Motion Trajectory: Three-Dimensional Vibration Conversion
Vertical Vibration: The electromagnet directly drives the hopper to vibrate up and down.
Torsional Swing Vibration: The inclined angle of the spring plates converts the vertical vibration into torsional motion around the vertical axis.
Spiral Ascension: The superposition of the two vibrations causes the parts to move upward along a spiral track within the hopper, while the "micro-jetting effect" generated by the vibration prevents parts from getting stuck.
III. Directional Sorting: Track Design and Screening
Optimization of Track Cross-Section: The track width, height, and cross-sectional shape (such as V-shaped or U-shaped) are designed based on the shape of the parts to ensure that only parts in specific orientations can pass stably.
Baffles and Limiting Mechanisms: Baffles are set at key positions on the track to block parts with incorrect orientations (such as height exceeding limits or direction deviations), forcing them to fall back into the hopper for re-sorting.
Air Blowing Assistance (Optional): For lightweight parts, air flow is directed to blow off parts with abnormal orientations, improving the screening accuracy.
IV. Output Control: Collaborative with CNC Lathe
Photoelectric Sensing System: Detects the number of parts at the discharge port. When the number of parts reaches the set value, the controller suspends the operation of the vibration disc to avoid overloading.
Linear Feeder: Sorts the parts from the vibration disc to the CNC lathe fixture. Usually, it uses electromagnetic or motor-driven linear vibration platforms to ensure the conveying speed matches the processing rhythm of the lathe.
V. Technical Parameters and Compatibility
Frequency Adjustment: Adjusts the power-on frequency of the electromagnet (typically 50-200Hz) through the controller to change the vibration intensity to adapt to different parts (such as ultra-small parts require high-frequency vibration).
Voltage Control: Supports half-wave/ full-wave excitation, and adjusts the voltage amplitude (such as AC 220V) to fine-tune the vibration amplitude, avoiding parts jumping off the track due to excessive vibration.
Multi-Size Compatibility: The hopper diameter range is 80-1000mm, capable of handling parts ranging from 0.05mm ultra-small to large workpieces. By replacing the hopper and track, production models can be switched.
Industry Application Value
Efficiency Enhancement: Replaces manual sorting, with an uploading speed of up to 3000-10000 parts per hour, reducing waiting time for machine stops.
Accuracy Guarantee: Through track design and screening mechanisms, ensures consistent part orientations, reducing the defect rate of parts processed by the lathe.
Cost Optimization: Reduces manual intervention, lowers labor intensity, and avoids contamination introduced by manual operations (such as in medical and food industries).
Further Discussion Directions: If it is necessary to optimize the design of the vibration disc for specific parts (such as irregular parts, brittle materials) to achieve data linkage, further in-depth communication can be conducted!
