This Servo Tip Dressing And Changing Combination Device supports external communication interfaces including a hard I/O port and various bus interfaces (configurable according to site requirements).
It uses carbide coated blades, enabling high-speed regrinding and simultaneous regrinding of the electrode caps on both the upper and lower motors of the spot welding clamp, resulting in concentric and perfectly aligned electrode end faces.
It features automatic electrode cap removal, automatic electrode cap feeding and installation, and an automatic copper collector, ensuring a clean and aesthetically pleasing work environment.
