Sugino MSPU-13 Inline Drilling Unit - Dual Spindle Head - 3.94" Stroke

Sugino Selfeeder Mechatric MSPU Dual-Spindle Drilling Unit

Model: MSPU | Configuration: 2-Spindle Multi-Head | Year: ~1986 | Serial: 560118

Product Overview

The Sugino MSPU Mechatric is an industrial-grade, automated drilling head optimized for high-volume production. This specific unit features an integrated 2-spindle multi-drill head, effectively doubling output per cycle. Unlike standard pneumatic units, the Mechatric series utilizes a mechanical feed system that ensures a constant chip load across both drill bits, providing the rigidity necessary for precision hole patterns in mild steel, aluminum, and cast iron.

Technical Specifications

• Drive Type: Mechanical Feed (Mechatric) with Electric Spindle Motor.
• Spindle Configuration: 2-Spindle Multi-Head (Fixed or Adjustable centers).
• Drilling Capacity: Approx. 1/2" (13mm) total capacity (split between spindles).
• Motor: 1/2 HP 3-Phase Industrial Induction Motor (Standard 230/460V).
• Spindle Speed: Approx. 3,000–3,600 RPM (verify via internal gearing).
• Stroke Length: 3.94" (100mm) maximum travel.
• Thrust: Mechanical drive delivers consistent force up to ~500 lbs.
• Mounting: Inline design for automated transfer lines or robot-end effectors.

Key Performance Features

• Doubled Throughput: The factory-matched 2-spindle attachment allows for simultaneous drilling of hole patterns, significantly reducing total cycle time.
• Mechanical Feed Precision: The Mechatric drive system eliminates the "plunging" effect common in air-only units, extending the life of cobalt and HSS bits during breakthrough.
• Automation Ready: Features integrated limit switches for "home" and "depth" signals, allowing for easy integration into modern PLC or robotic control systems.
• Legacy Reliability: Built during Sugino's peak manufacturing era in the mid-80s, these units feature heavy-duty castings and oversized internal gears designed for decades of service.
