Description
Condition
Used (Great / Asset Marked).
This magnetic indicator stand is in great used condition. The articulating arm moves freely when unlocked and rigidifies instantly when the central knob is tightened. The magnetic base switch functions correctly, and the clamp assembly is intact. Cosmetic Note: The base features a hand-engraved “Mitsubishi” logo on one side. This appears to be an asset mark from a previous life in a Mitsubishi manufacturing facility or workshop, adding a touch of industrial history to the tool without affecting its function.
Product Overview
The BIG Daishowa AML-M is the “Mini-Mini Long Arm” version of the famous Accu Stand series. Unlike hydraulic bases that can leak or lose pressure over time, this stand utilises a purely mechanical cam-locking mechanism. A single turn of the central knob simultaneously locks all three joints (base, elbow, and wrist) with rock-solid rigidity.
The “M” designation points to its compact magnetic base, which offers a powerful hold relative to its small footprint, making it ideal for tight setups in CNC lathes or machining centres where space is at a premium. The clamping head is versatile, featuring a standard 8mm hole for dial indicators and a dovetail groove for directly mounting lever-type test indicators (DTIs). This “Long Arm” variant provides extended reach compared to the standard short-arm models while maintaining the compact base profile.
