The Application of FGI FD100 Frequency Converter in Engraving and Milling Machines
A type of CNC machine, the engraving milling machine also possesses both metal engraving and cutting functions. It typically uses small tools, high power and high-speed spindle motors for CNC milling machines. CNC engraving milling machines have gradually become essential professional tools in various industries, widely used for the one-time completion of rough and fine processing of precision molds, batch processing of aluminum products, shoe mold manufacturing, fixture processing, watch lens industry, and other fields.
The spindle system is an important component of CNC engraving milling machines, and its performance has a significant impact on the overall performance of the CNC engraving milling machine. Among them, the inverter, as the heart of the spindle system, is an indispensable key component, and the quality of the inverter affects the performance of the entire CNC engraving milling machine to a certain extent.
1.Application advantages
The spindle system is the core component of the milling and engraving machine. To enhance work efficiency, large milling and engraving machines are equipped with multiple spindle heads. One frequency converter can simultaneously drive multiple spindle motors to operate. By applying the FGI FD100 series frequency converter, the performance of the spindles can be significantly improved:
Quickly reduce speed. The frequency converter enables the machine to decelerate to 0 Hz within 1 second, keeping the motor shaft stationary.
Under high-frequency operation, the current remains stable and the noise is low.
The speed fluctuation is minimal within the full speed range.
The low-speed torque is large, which can ensure low-speed cutting.
2.Performance requirements
The speed fluctuation and current fluctuation are both small within the full speed range.
The low-speed torque is large, which can ensure low-speed cutting.
The time for acceleration and deceleration should be as short as possible.
Excellent low-frequency torque characteristics, with the lowest processing speed being below 300 r/min.
3.Usage effect
The start-up and shutdown time of the motor can reach 0.5 seconds: Based on the excellent control performance of the FGI FD100 series frequency converter, it has a good control effect to meet the strict requirements of the engraving machine for instant start and stop, which can greatly improve the efficiency of engraving workpieces.
The braking effect is remarkable, achieving an instant locking without vibration effect: Due to the excellent deceleration and shutdown control performance of the FGI FD100 series frequency converter, it meets the requirements of instant stop without vibration, effectively preventing the engraving machine from scratching the workpiece and ensuring product quality and process.
The low-frequency torque is large: The excellent low-frequency characteristics of the FGI FD100 frequency converter (150% of the rated torque can be achieved at 0.25Hz) can meet the process requirements of the engraving machine for low-frequency drilling and other operations, with a wide frequency adjustment range.
The motor noise is significantly reduced: The full three-phase modulation technology throughout the process, the control is more stable, and the noise is lower.
The operating current is low: The frequency conversion operating current is around 1.2A, with excellent control performance, the current is more stable.
The volume is smaller, the structure is detailed: Adopting a half-book structure, the installation space is smaller; using Tianchuan Electric's dark gray color, it has a rich texture and a sense of technology, and the appearance is more beautiful.
Installation and debugging are more convenient: Using plug-in type I/O boards, wiring is convenient; the keyboard has the function of parameter copying and downloading, greatly reducing the debugging workload.
After applying the FGI FD100 series frequency converter, the advantages are significant. It features higher precision, energy conservation, reduced noise, and a marked improvement in work efficiency and reliability. This is of great significance for the performance and processing efficiency of engraving and milling machines.
