Description
CNC vertical lathes offer significant advantages in the machining of forklift wheel hubs. Through advanced processes such as turning-milling combination, they can substantially improve production efficiency and machining accuracy while reducing labor intensity, making them a critical choice of equipment in the forklift wheel hub manufacturing sector.
Internal and External Cylindrical Surface and End Face Machining: Forklift wheel hubs typically have large diameters (e.g., Ø200 mm – Ø600 mm or even larger). The large-diameter worktable of a vertical lathe can easily accommodate and perform high-precision turning, ensuring the dimensional accuracy of the journal for bearing installation and the flatness of the sealing end face.
High-precision shoulders and locating surfaces: The mating shoulders between the hub and the rim or brake drum, as well as the mounting surfaces, require extremely high standards for runout and flatness. Vertical lathes can complete the finishing of these critical surfaces in a single setup, reducing errors caused by repeated repositioning.
CNC Vertical Lathe. This CNC machine tool features a vertically mounted spindle and a horizontal worktable that rotates like a large turntable. Imagine it as a precision giant “potter’s wheel” combined with a “gantry crane”-style cutting tool system, specifically designed for machining large, heavy, and awkward-to-lay-flat parts such as discs, wheels, covers, and rings.
It excels at machining rotary components where radial dimensions far exceed axial dimensions. Typical products include:
Large discs/covers/flanges: Wind turbine gearbox end covers, large valve flanges, pump casing end covers.
Wheel hubs and wheel-type components: railway wheels, turbine discs, large pulleys.
Short, thick cylindrical/sleeve-type components: large bearing housings, rolling mill frames.
Composite machining: Completes multiple processes in a single setup, including face turning, external turning, boring internal holes, grooving, and even milling and grinding.
