Application of Hxdwh 23 bit absolute value ac servo motor LDD series matching Ω m-n1 series servo driver in precision carving machine
Application of numerical control engraving machine
CNC Engineering and milling machine is a kind of CNC machine tool. Metal precision engraving machine can be used for non-contact cutting and drilling of metal or non-metallic plates and pipes. It is especially suitable for laser cutting of stainless steel plate, iron plate, silicon chip, ceramic chip, titanium alloy, epoxy, A3 steel, diamond and other materials. It is a precision machining equipment with multi axis interpolation by CNC system. The equipment has the advantages of stable and reliable operation, good processing quality, high efficiency, simple operation and convenient maintenance. Through milling, drilling, grinding and other ways, it is widely used in 3C, precision abrasives, medical and other fields. With the rise of 5g industry, its market in 3C industry is particularly huge.

Summary:
The common composition of the engraving machine is shown in the figure on the left, including left and right moving X axis, Y axis moving back and forth, Z axis moving up and down, high-speed rotating spindle and tool magazine axis (t axis) for automatic tool change. X, y, Z and t axes are controlled by servo, and the main axes are controlled by frequency converter. The processing parts are fixed on the worktable by the fixture, with the help of the fast and stable response of XYZ triaxial, to ensure its high-precision processing effect, most parts (mobile phone keys, glass cover plate, metal frame) on the mobile phone have its participation in processing.

The CNC system is connected with Ω m-n1 one drive four drive and electric spindle system through EtherCAT bus. Under one drive four drive, the system controls X-axis 750W, Y-axis 750W, z-axis 750W and magazine axis 400W.
Features of the scheme
- Form advantage
Ω m-n1 four axis integration, in this application, the left-right moving x-axis, the back-to-back y-axis, the up-down moving Z-axis and the tool magazine axis for automatic tool change are all controlled by servo, and the field using multiple drivers now only needs one multi axis bus driver. Moreover, one drive four drive has high synchronous performance, no delay in communication, which is economical and efficient.
- Small size
Ω m-n1 is small in size, which saves space for the application site with narrow site. And there are three different installation methods, easy to install and easy to use.
- Strong performance
With the real-time performance of EtherCAT bus and the responsiveness and stability of Ω m and Huada LDD motor, the machining accuracy of the whole system is guaranteed. In addition, Ω m-n1 bus driver adopts hardware current loop, and excellent current loop response is the guarantee of responsiveness.
- Adaptive filtering algorithm
The X, y and Z axes of the equipment are driven by screw rod. The interference of resonance points in the system will greatly affect the machining accuracy and surface smoothness. The algorithm of Ω m-n1 driving adaptive filtering can automatically identify the resonance points on the system, and effectively suppress the resonance points, providing the most favorable guarantee for the machining accuracy of the system.
Project difficulties
For the engraving machine industry, the quadrant pattern is a headache in metal processing. The main reason is that the response of the interpolation shaft always lags slightly at the reversing point during the matching processing.
Application effect
- The quadrant bulge suppression function of Ω m-n1 driver can effectively solve the problem of quadrant ripple.
- In addition, Ω m-n1 is also optimized to solve the problem of tool pattern. With the help of torque observer function, the torque ripple in the machining process is guaranteed to be within 1%.
- The special customized spindle anti-collision function is developed to monitor the torque change from time to time, and stop immediately at the moment of collision, so that the collision problem caused by improper operation in the field processing process can be solved.
