Technical Overview

Universal jointed magnetic stand with 300N holding force, 159mm reach, mechanical lock system, and ±4° fine adjustment for dial test indicators.

Key Features

  • Centralized mechanical locking mechanism clamps all jointed components simultaneously with one adjustment knob
  • Switchable ON/OFF permanent magnet provides a secure 300 N vertical clamping force on ferrous surfaces
  • Integrated fine-adjustment feed wheel allows precise micro-positioning of indicators within ±4°
  • Universal mounting fixture supports 6.0 mm, 8.0 mm, and 9.53 mm (3/8") stem holes plus an integrated dovetail groove
  • Compact V-groove magnetic base (36 x 30 x 36 mm) mounts easily onto flat, curved, or cylindrical machine frames
  • Provides a flexible 159mm working radius with free articulating motion for versatile measurement angles

Industrial Applications

1. CNC Spindle Runout and Taper Alignment

Mounting a dial test indicator via the dovetail groove to verify the internal taper runout of a CNC spindle. The articulating jointed arm is extended to position the indicator probe precisely inside the spindle head. The operator rotates the spindle manually to detect radial runout.

Problem Solved

Eliminates indicator displacement or flex during spindle rotation. The centralized mechanical locking mechanism completely rigidifies the joints, ensuring sub-micron accuracy without micro-deflections.

2. Lathe Chuck Cylindrical Workpiece Concentricity Check

Placing the V-groove magnetic base onto the curved headstock or carriage of a lathe. By utilizing the 300 N holding force, the stand holds a dial indicator perpendicular to a chucked cylindrical shaft while the workpiece is rotated to verify concentricity and alignment before cutting.

Problem Solved

Solves the problem of mounting stands on round or uneven machine castings. The compact 36x30x36 mm magnetic base with built-in V-groove ensures a stable, non-slip grip under vibrations.

3. Surface Plate Parallelism and Flatness Inspection

Utilizing the stand on steel surface plates or reference fixtures to carry out high-precision flatness and height mapping of machined parts. The operator uses the fine adjustment wheel (±4°) to establish a zero-reference baseline on the indicator face with absolute control.

Problem Solved

Prevents the awkwardness and inaccuracy of coarse manual indicator positioning. The fine feed wheel enables rapid, microscopic leveling of the stylus, eliminating setup drift and saving inspection time.
