You Ji VHL Series – Vertical Turning Lathes with Side Milling Head
The You Ji VHL Aerospace Components Series comprises advanced vertical turning lathes equipped with side heads, specifically designed for aerospace manufacturing applications. These machines combine a vertical ram with an integrated horizontal side head, facilitating multitasking operations such as turning, drilling, tapping, milling, and grinding.
The horizontal ram extends past wide diameters to access difficult-to-reach areas, enabling the use of shorter tools and eliminating the need to transfer parts to other machines. The side head allows for side milling without a right-angle head and supports pinch-turning of thin-walled aerospace components like engine casings.
