Precision Measurement of Precision Screws
Estimated reading time 2 minutes
When manufacturing critical components like medical bone screws and their corresponding HexLobe drivers, or precision screws in Aerospace precision is paramount. The complex geometry of these parts demands non-contact measurement tools that ensure both accuracy and ease of use. Focus Variation Technology offers non-contact measurement precision
The focus variation technique provides measurement of multiple and critical areas on the screw, driver, and socket.
- Comprehensive Thread Analysis: Using the Real3D (360° Acquisition), it is easy to measure all key parameters of the screw thread form. This includes the Inner Diameter (ID), Outer Diameter (OD), tip and root radius, plus, crucially, surface finish. The accuracy and finish of the thread profile is critical as it determines the ease of insertion and the long-term durability of the attachment.
- HexLobe Head and Driver Compatibility: It is important that the Hexlobe socket and driver match precisely to prevent damage to the tool and the screw head to ensure that in a clinical setting, the operation site is protected from potential injury caused by the tool slipping during use. The high depth of focus provided by Focus Variation provides the ability to measure the intricate internal geometry of the HexLobe socket and the driver to ensure accurate mating.
- CAD Comparison: Both the measured thread profile and the HexLobe screw head can be compared directly with the designer’s CAD file, ensuring the manufactured parts meet the exact design specifications.
By using Focus Variation Technology, manufacturers can ensure that every orthopaedic screw and driver meets the highest standards for performance, durability, and patient safety.
