24" Pratt & Whitney Motorized Tilting Rotary Table | M-1896 | 2-Sec Vernier

Pratt & Whitney 24" Motorized Tilting Rotary Table

Model: M-1896 | Diameter: 24" | Universal Positioning

Professional Overview

The Pratt & Whitney M-1896 is a heavy-duty, high-precision motorized tilting rotary table designed for the most demanding aerospace and toolroom applications. Unlike standard horizontal tables, the M-1896 offers universal positioning, allowing operators to rotate workpieces 360 degrees while simultaneously tilting the table to achieve complex angles for spherical tangs, intricate curves, and multi-axis drilling. Built with the massive cast-iron construction Pratt & Whitney is known for, this unit provides the rigidity necessary to maintain sub-thousandth tolerances even under heavy load.

Key Performance Features

• Motorized Efficiency: The integrated motorized drive eliminates the fatigue of manual rotation, providing consistent feed rates for circular milling or rapid indexing between operations.
• Extreme Rigidity: Weighing approximately 900 lbs, the M-1896 uses its mass to dampen vibration and resist deflection, ensuring that your setup remains "locked-in" regardless of the tilting angle.
• Low-Profile Design: With an overall height of approximately 7 inches when in the horizontal position, this table maximizes your machine’s vertical "Z-axis" envelope.
