[0030] The chips enter the auxiliary chip removal groove 4 for chip removal. The chips first enter the upper part 401 of the chip removal groove. Since the upper part 401 of the chip removal groove is an irregular U-shaped groove, the cross-sectional area of ​​the auxiliary chip removal groove 4 is increased at the same depth, expanding the chip entry range. After the chips enter smoothly, they reach the lower part 402 of the chip removal groove. The lower part 402 of the chip removal groove is funnel-shaped, which gradually widens the chip discharge path and forms a negative pressure during the chip flow, increasing the chip discharge speed. Finally, the arc-shaped part 403 reduces the resistance during chip discharge. Through the ingenious design of the auxiliary chip removal groove 4, the chip discharge efficiency is significantly improved, chip accumulation is reduced, and it is beneficial to improve machining quality and tool life. The four sets of threaded holes 6 facilitate the fastening connection between the connecting plate 2 and the power end, improving the stability of the milling cutter head 1 during operation.

[0035] Working principle: The chips enter the auxiliary chip removal groove 4 for chip removal. The chips first enter the upper part 401 of the chip removal groove. Since the upper part 401 of the chip removal groove is an irregular U-shaped groove, the cross-sectional area of ​​the auxiliary chip removal groove 4 is increased at the same depth, expanding the chip entry range. After the chips enter smoothly, they reach the lower part 402 of the chip removal groove. The lower part 402 of the chip removal groove is funnel-shaped, which gradually widens the chip discharge path. During the chip flow, negative pressure is formed, which increases the chip discharge speed. Finally, the arc-shaped part 403 reduces the resistance when the chips are discharged. Through the ingenious design of the auxiliary chip removal groove 4, the chip discharge efficiency is significantly improved, chip accumulation is reduced, and it is beneficial to improve the processing quality and tool life. After the bolt passes through the tool body, it is connected to the threaded hole 5 to fix the tool body at the tool holder part 3, which facilitates the installation and replacement of different tool bodies and improves the flexibility of use.

[0036] The PTFE layer has excellent self-lubricating properties, effectively reducing the friction coefficient between the chips and the inner wall of the chip removal groove, further improving chip removal efficiency.
