Bone Screw Measurement with Real3D Technology

The production of turned parts, such as bone screws, presents several challenges that require expertise and precision.

Complex geometries and intricate thread patterns: Requirement of advanced CNC programming and skilled operators to produce consistent, high quality parts.
Recess geometry on the head: Manufacturing bone screws with a hexagonal slot is challenging, but it enhances the connection, eliminates axial force, and ensures a secure fit along the edges.
Surface finish: directly affects the part’s performance, durability, and aesthetic quality

Overcoming these challenges is essential to ensure the reliability and effectiveness of bone screws in medical applications. This measurement report shows the high precision measurement of a bone screw with the FocusX and the Real3DUnitX. Using Real3D technology the following critical parameters can be evaluated: shaft diameter and concentricity of the shaft to the thread; edge radius and rake angle on the tip; thread pitch, angles, radius, core diameter, and outer diameter; and head diameter, angles of the hex geometry, and countersink angle.
