Marposs's M39S is an ultra-high precision scanning system designed to inspect matched cylindrical components with sub-micron accuracy. Engineered for bore and shaft measurement, the system scans internal and external diameters along the full axial length to evaluate matching clearance and generate detailed graphical profiles of the matched surfaces.

Using advanced pneumatic gauging technology combined with Marposs air-to-electronic conversion, the M39S delivers exceptional repeatability for high-precision components such as injectors, pumps, and hydraulic valves. The system supports applications including selective assembly, match grinding, match honing, pre- and post-process measurement, part classification, and in-line quality control.

The M39S measures:

• Maximum, minimum, and average inner and outer diameters
• Matching clearance values
• Taper, barrel shape, and other form errors
• Diameter values at programmable axial positions

Its compact design allows easy integration into automatic machines and production lines, even in limited spaces. Built with robust and standardized pneumatic components, the M39S ensures long-term reliability and stable metrological performance in demanding manufacturing environments.
