VERTICAL DRILLING CENTER WDC
The NILES-SIMMONS WDC is a compact drilling center specifically designed for performing all drilling, threading, and countersinking operations on high-speed railway wheels. The wheel drilling center is based on a cross-bed construction.
The machine features a swiveling head, allowing operations with head tilts from +16° to ‑120°. Thanks to the direct rotary and swivel axes, the WDC offers ideal conditions for achieving the highest precision on the workpiece. For 3‑axis machining or positioning operation, the rotary and swivel axes can be hydraulically clamped at any position. Using rotating tools, wheel diameters between 700 mm and 1250 mm can be machined.
Value Added:
- Machining from +16° to ‑120°
- 3‑axis machining and positioning operation
- Machine bed made of generously dimensioned, vibration-damping cast part.
- Highest precision and cost-effectiveness
- Machine leveling via leveling shoes on the machine bed
- Maximized distance between the linear guides for increased precision of the machine construction
