Taumel BK-1500/NM Orbital Riveter

Serial Number: D-H-49 | Year of Mfg: 1978 | Condition: Operational

Overview

The Taumel BK-1500/NM is a premium orbital riveting machine built for high-accuracy assembly applications. Unlike traditional impact riveting, the orbital process uses a rotating peen to "knead" the material into shape, reducing the force required and virtually eliminating the risk of material fracture.

Manufactured in 1978, this benchtop model is currently mounted on a heavy-duty floor stand, providing a rigid and stable platform for production. It is the ideal solution for manufacturers working with fragile materials or those requiring a polished, uniform rivet head without the loud impact noise of conventional presses.

Technical Specifications

• Heading Capacity: Up to .580" (15mm) diameter in mild steel.
• Stroke: Variable from 0 to 1.57" with .001" micrometer adjustment.
• Drive Type: Pneumatic force generation with electric orbital movement.
• Miter Range: Standard 5° working angle orbital head.
• Cycle Control: Fully adjustable pneumatic timer and pressure regulator.
• Electrics: 110V/220V Single Phase Control (Modular design).
• Air Supply: 60 – 90 PSI Standard.
• Weight: Approx. 350 lbs (with floor stand).

Key Performance Features

• Gentle Cold-Forming: The orbital "kneading" action creates a clean, polished, non-porous surface on the rivet head without changing the molecular structure of the material.
• Quiet & Vibration-Free: Fully O.S.H.A. compliant for noise levels, making it suitable for clean laboratory or electronic assembly environments.
• Precision Depth Control: The integral micrometer stroke adjustment allows for high repeatability, ensuring every rivet is formed to the exact same height and diameter.
• Versatile Tooling: Compatible with standard Taumel orbital peens for flat, crown, conical, or flared head finishes.
• Modular "NM" Design: The No-Motor configuration (as specified in this model) is designed for easy maintenance and can be easily adapted for custom automation setups.
