Welding seam often needs polishing and grinding operation after completion, the earliest welding seam polishing machine function is single, mainly relies on polishing and grinding, and the efficiency is low, and then gradually appears some milling equipment that can mill and polish this kind of welding seam.

[0003] And some products consider welding strength, and welding often adopts double-sided processing mode, and the front and back of the welding seam of two materials will leave a welding seam, based on the high-precision requirement of finished product quality, the welding seam needs to be milled after welding to ensure the high precision and high flatness of the finished product. The earliest milling equipment is to mill one side of the product to be processed, and then turn over to mill the other side, which cannot mill both sides at the same time, and the whole milling process is relatively complicated, and the milling efficiency is slightly low.
