Vertical Lathe: Heavy-Duty Turning for Massive, Non-Rotational Components

What is a Vertical Lathe?

A vertical lathe (vertical turning center/VTC) clamps workpieces vertically on a rotating table, enabling stable machining of oversized, unbalanced parts (up to 25-ton rings, gears, or molds) impossible for horizontal lathes.

Types of Vertical Lathes

1. Single-Column
   • Compact for parts ≤ Ø2.5m (e.g., flanges, wheels).
2. Double-Column
   • Gantry-style for Ø3–12m wind turbine bearings.
3. Turret-Type
   • 12-station tool turret for high-mix production.

Key Advantages

• Gravity Utilization: Prevents part deflection during heavy cuts.
• Floor Space Savings: 40% smaller footprint than horizontal equivalents.
• Chip Management: Chips fall away freely, avoiding recutting.
• Rigidity: Handles >1mm depth of cut in hardened steel.

Applications

• Mining: Crusher rings, excavator hubs.
• Power Generation: Hydroelectric turbine runners.
• Shipbuilding: Propeller hubs, rudder stocks.

Operation Steps

1. Part Mounting: Bolt workpiece to table using T-slots.
2. Tool Selection: Roughing inserts (IC808 grade) for stock removal.
3. Facing/Boring:
   • Table rotates at 5–200 RPM.
   • Ram-mounted tools face surfaces and bore holes.
4. In-Process Measurement: Touch probes verify diameters.
