30" Pratt & Whitney Motorized Horizontal Rotary Table | 115V | Fincor Control

Pratt & Whitney 30" Plain Motorized Horizontal Rotary Table

Model: 30" Motorized | Diameter: 30" | Power: 115V (Fincor Control)

Professional Overview

The Pratt & Whitney 30" Plain Motorized Rotary Table is a high-precision industrial workholding device designed for critical indexing and continuous 360-degree machining. Built with the legendary "heavy iron" rigidity associated with the P&W brand, this motorized unit is ideal for precision boring, milling, and high-accuracy inspection tasks. This specific configuration features a horizontal orientation and a self-contained motorized drive system that allows for rapid, reversible indexing without manual fatigue.

Technical Specifications

• Table Diameter: 30" precision-ground work surface
• Table Height: Approximately 8" from base to surface
• Workpiece Capacity: Designed to support heavy loads, typically up to 1,200 lbs (varies by specific model sub-type)
• T-Slots: Features 7 to 8 parallel or radial 1/2" T-slots for secure workholding
• Indexing Accuracy: * Dial Graduations: 1-minute increments (1/60°)
• Vernier Graduations: High-precision readings down to 2 seconds of arc
• Drive System: * Motor: Typically 1/4 to 1/2 HP variable speed DC motor
• Control: Equipped with a Fincor 2300 series or similar control for forward/reverse variable speed
• Manual Override: Includes a fine-feed manual dial and manual clamp for locked-position machining

Key Features & Condition

• Motorized Precision: The integrated Fincor control provides smooth, variable-speed rotation, making it suitable for both rapid positioning and power-feed circular milling.
• Extreme Rigidity: The massive cast-iron base ensures maximum vibration dampening, maintaining accuracy even under heavy cutting loads.
• Operator Ready: Most units from this era are designed for 115V single-phase power, allowing for easy integration into standard shop environments.
