Spi CMS160928006 Magnetic Indicator Base Articulated Arm

Product Description

The SPI CMS160928006 is a magnetic indicator base designed to hold dial indicators, test indicators, and similar precision measuring instruments during setup and inspection work. The base uses a powerful magnetic mount that activates and deactivates via a control lever, allowing secure attachment to ferrous machine surfaces such as lathe beds, milling machine tables, surface plates, and workholding fixtures. The articulated arm provides multi-axis positioning so the indicator can be located exactly where the measurement is needed. Licensed machinists, toolroom technicians, and quality control inspectors are the primary users of this tool.

This indicator base is suited for machine shop environments, toolrooms, and inspection stations where precise workpiece measurement or machine calibration is required. Typical applications include runout checks, surface parallelism verification, spindle alignment, and part setup on manual or CNC machine tools. The 385 mm rod length provides reach for accessing recessed or offset measurement points without repositioning the base.

Key Features

• Articulated arm design allows multi-axis indicator positioning
• 80 kg magnetic pull force for stable attachment on ferrous surfaces
• Base footprint of 2.36 inches length by 1.97 inches width for compact placement
• Rod length of 385 mm extends reach to offset or recessed measurement points
• On/off magnetic control lever for safe repositioning without indicator disturbance

Compatibility

Designed as a general-purpose magnetic indicator base compatible with standard dial indicators and test indicators that use conventional dovetail or post-style mounting stems commonly found in machine shop and inspection applications.

Installation Notes

Power down and lock out any machine tool before attaching or repositioning the indicator base on the machine surface. Ensure the mounting surface is clean and free of chips or coolant that could reduce magnetic holding force. Tighten all arm joints and clamp knobs fully before taking measurements to prevent indicator drift. This tool does not require tools for assembly but should be inspected regularly for wear on the articulating joints that could compromise rigidity.
