Bruker NPFLEX 3D Optical Microscope

Bruker NPFLEX 3D Optical Microscope

Large-sample, non-contact measurement and analysis

Bruker NanoSurfaces

The NPFLEX provides the most flexible, non-contact, 3D areal surface characterisation for such large samples as orthopedic medical implants and the larger parts in aerospace, automotive and precision machining industries.

The NPFLEX also provides data density, resolution, and repeatability beyond what is possible with contact instrumentation, making it ideal as both a complementary technology or as a stand-alone metrology solution. The NPFLEX enables superior flexibility, accuracy, and throughput for precision manufacturing, providing an easy path to tighter tolerances, more efficient processes, and better end products.

Measurement Flexibility to Characterise Unique Shapes and Angles

  • Innovative design accommodates samples of widely varied size and shape, up to 13-inches tall
  • Open gantry, custom fixturing, and optional swivel head reveal previously inaccessible areas of interest

Definitive Results from High-Density, 3D Areal Information

  • Each measurement contains complete surface information for multiple analyses
  • More data leads to better decisions

Revealed Detail at Nanometer Resolution

  • Interferometry provides sub-nanometer vertical resolution at every pixel
  • Industry-proven technology ensures statistical certainty to achieve tighter tolerances

Throughput and Efficiency Gains through Rapid Data Acquisition

  • Minimal sample preparation and measurement setup reduces time to result
  • Large field of view characterises more information about surfaces than contact measurement techniques

Precision Surface Characterisation Yields Quantitative Analysis of Cutting Tool Coatings and Wear

The ability to quantitatively analyse surface coating structure and wear is an important qualification within the precision tooling industry to assess cutting tool life under different cutting conditions. This however can be a challenging prospect for CMM's due to the lack of 3D measurement resolution, and for stylus based tools due to the complex shape and often smaller feature size of the tools. In a recent development by Bruker Surface Analysis group the NP Flex was applied to the study of drill bit coatings under controlled conditions to assess the subtle changes of different coatings.

The study utilised the nanometre vertical measurement sensitivity of the 3D interferometric technique employed on the NP-FLEX to assess surface wear after only a few drilling processes. Qualifying surfaces to new ISO2012 standards for 3D surface parameters, such as Sa and Str, provide a statistical approach to understanding wear and removes any subjective assessment which can lead to incorrect conclusions. The case study investigated the pre and post wear surfaces at the apex of the drill bits in QC environment as well as along leading edge cutting regions to quantitatively assess coating wear. From this study an understanding of the coating of choice was determined.
