Machine Shop Solutions

Problem: Complicated centering applications demand time-consuming readjustments throughout the process. Solution: A fixed-face design simplifies and speeds up the centering process while also improving accuracy.

Precise Center Location With Even Spindle-Wobbles

Look to this handy centering device for a faster and simpler way to center a workpiece, part or fixture. It is compatible with NC, EDM and other hard-to-turn spindles and works across all horizontal, vertical, internal and external angles. As the spindle rotates, the centering indicator face remains stationary and always faces the operator. That way, you free up both hands to accurately position the machine table. Use the Co-Ax Indicator with the machine spindle running, and centering conditions are closely simulated because the influence of power transmission, lubricant flow, bearing characteristics and torque are already integrated into the reading.
Delivers quick, accurate centering in boring and milling set-ups


  • Provides simplified method for centering workpiece or fixture on horizontal or vertical machines, external or internal diameters - also with NC, EDM and other hard to turn spindles.


  • Indicator face remains in fixed position while the machine spindle rotates, allowing operator to accurately position machine table.
  • Locating accuracy: to within .0002" of true center
  • It is recommended that operating speed not exceed approximately 800 RPM.
