The conventional processing method is to use three-jaw clamping for clampable positions, and use tooling to turn the products at positions that cannot be clamped. However, when processing the grooves of the products, the thickness between the outer wall and the inner wall of the grooves becomes thinner and thinner, the product will vibrate and the product will be deformed, resulting in product scrapping, which in turn affects the yield rate of thin-walled special-shaped products.

[0003] Therefore, it is urgent to propose a thin-walled special-shaped workpiece processing tooling to solve the above problems. Utility Model Content
