Spindle Error Analyzer Hardware

The probe mounting hardware and precision targets are critical pieces of the SEA system. Accuracy of the measurements are dependent on stiffness and reliability of the mounting hardware.

Probe Mounts

Precision probe holders are designed to maintain precise perpendicularity required for accurate measurement of high-resolution error motion. Also available are more generic adjustable probe holders for single channel measurements.

3 Probe Nest	5 Probe Nest	3 Probe µNest	Lathe Adaptor	Adjustable
X, Y, and Z axes measurements with a three channel system.	2X, 2Y, and Z measurements for tilt and error motion with 5 channel systems.	Smaller size 3 probe nest for micromachining applications.	Fits in lathe tool holder and holds a standard three probe nest.	For mounting probes where standard probe nests can not be used.

Master Ball Targets

Master targets are manufactured to exacting standards. Our master ball targets boast a roundness of better than 50nm (2 µinch).
The ball targets are 50 µm off center to induce a fixed runout. This runout is used to create a "once around" signal to determine angular location. The dual master ball is required for five channel systems.
A precision 1 inch gage pin with two finished surfaces is also available.

Single Master Ball (1")	Dual Master Ball (1")	Small Single Ball (0.5")	Precision Gage Pin (1")
One precision ball for three channel systems.	Two precision balls for five channel systems enabling measurements of tilt as well as other error motions.	One precision 0.5" ball for three channel systems on smaller and micromachining machine tools.
