1997 Universal Automatic #5.5 Dual Head CNC Drill

Model 5.5 | S/N 3140 | CNC Series 2 Control | Dual Opposed Heads

Overview

The Universal Automatic #5.5 is a high-speed, dual-end secondary operation machine designed to eliminate bottlenecks in high-volume production. This 1997 unit is the "Goldilocks" vintage—modern enough to feature the Series 2 CNC Control, yet built with the heavy cast-iron rigidity that made U.A.M. the industry standard for secondary ops.

By utilizing Dual Opposed Heads, this machine performs simultaneous drilling, tapping, or milling on both ends of a part, effectively doubling the output of a standard single-head machine.

Key Features & Dealer Benefits

• Simultaneous Multi-End Machining: Factory-set logic allows heads to fire simultaneously, sequentially, or in a "peck" cycle, reducing production time by 50% compared to single-head setups.
• CNC Series 2 Precision: Unlike older pneumatic models, the electronic feed control ensures a constant chip load, providing superior depth control and significantly extending tool life.
• Rapid Approach & Retract: Programmed "Rapid" moves to the part face followed by precision "Feed" rates optimize cycle times for high-volume runs.
• Automated Fixturing Interface: The electrical cabinet is pre-wired for seamless integration with pneumatic collet fixtures, rotary dial tables, or bowl feeders.
• Production-Ready Base: Features a massive built-in coolant reservoir and full-length chip tray designed for continuous flood-coolant operations.
