Sawing and Polishing Unit Increases Analysis Speed

Dec. 27, 2016

Creating micrographs, or cross-sectional views, of crimped connections with conventional methods and chemical etching is time-consuming and requires strict adherence to on-the-job safety regulations. However, the Schleuniger MicroGraph System allows users to safely create high-quality cross-sectional views in a fraction of the time needed with conventional methods.


Schleuniger’s SawPolish Units offer first class cutting quality with a carbide saw blade that makes subsequent polishing process unnecessary in many cases. This reduces costs as well as overall processing time.


Sawing can be further optimized using different sawing blades for different materials or small wires down to 0.03 mm2 (32 AWG).


For applications that do require polishing, a key benefit of Schleuniger’s SawPolish Units is that the sawing and polishing processes are combined in one device. The polishing disc is in line with the saw blade so the sample can be cut and polished in one motion. Thus, test samples can be prepared in one step without having to remove the sample holder and processing time is minimized. Other, less advanced, solutions split sawing and polishing into two separate devices, thereby increasing processing time.


The new SawPolish Unit 6 Comfort also offers an adjustable mechanical stop with digital display that ensures repeatable cut positioning. Furthermore, a digital magnifier with a four-step zoom capability improves cutting visibility and is ideal for smaller applications. Sample holders can be easily and securely inserted into the SawPolish Unit using a tool-less, quick-change mechanism.


The wide range of capabilities on the various machine versions allows a broad spectrum of crimped and welded connections to be easily processed. Numerous, interchangeable sample holders are available to support a variety of applications, including standard crimp and welded connections as well as potted connectors.


The SawPolish Units are compatible with the ElectrolyteStaining Unit and the MacroZoom Unit 1.3 to form the MicroGraph System for complete crimp cross-sectional analysis.
