Inspection and Measuring Fixturing
Use these components in coordinate measuring machine (CMM) applications to raise a workpiece and reliably position it on a fixture plate with 1/4"-20 holes. They are not for use in machining applications.

Hold-down clamps thread directly into a fixture plate, tower, or compatible component. Slide the clamp down its shaft and press into place against the workpiece for a light hold. They're also known as tension spring clamps. Wire clamps have a slimmer profile than standard, making them good for clamping small parts or minimizing contact area for additional visibility.

Fixture plates have a grid of 1/4"-20 threaded holes spaced 1/2" apart for attaching components. Alpha-numeric markings around the edges of the plates make it easier to identify holes and repeat tasks. Use aluminum plates with CMMs and optical comparators. Use acrylic plates on vision systems. They are transparent to provide your system with a view of the workpiece.

The height of fixture towers makes them useful for holding large parts. They have a grid of 1/4"-20 threaded holes spaced 1/2" apart for attaching components. Alpha-numeric markings around the edges of the towers make it easier to identify holes and repeat tasks.
Use an angle plate to mount components at a right angle.

Quick-Change Lathe Tools and Holders
Reduce tooling setup time—install the holder once and alternate between applications by switching out the bit. Once the holder has been aligned with the centerline of the lathe, the locking system ensures alignment repeatability from tool to tool.

Combine a carbide insert with a compatible internal profiling holder to create a tool that can contour the interior wall of a hollow workpiece. When one edge of the insert dulls, just rotate it in the holder to use another side.
C3 carbide inserts are abrasion resistant and less likely to chip or crack than C6 carbide when cutting aluminum, brass, and bronze.
C6 carbide inserts hold up better than C3 carbide when making cuts in steel and stainless steel.
