Ultrasonic disk cutter and assembley, model 170
The Model 170 Ultrasonic Disk Cutter can swiftly generate disk, cylindrical, and rectangular TEM specimens from hard/brittle materials including ceramics, semiconductors, and geological substances without mechanical or thermal damage. It fabricates disk specimens using materials as thin as 10m, as well as cylindrical rods up to 10mm long, from bulk samples or rectangular wafers, which are then utilised to produce cross-section TEM specimens.
Optimised Ultrasonic Cutting
Wafers are created using an ultrasonic method that combines the 26 kHz vibration of two lead zirconate titanate crystals. An abrasive slurry of boron nitride or silicon carbide is used as the cutting medium. This fast cutting technique reduces specimen loss and gives excellent samples in a matter of minutes. When the tool comes into touch with the specimen plate, an automated terminator stops cutting.Â
The cutting tool motion is generated by the excitation of lead zirconate titanate crystals vibrating at a frequency of 26 kHz. A coarse slurry of boron nitride or silicon carbide is used as the cutting medium. The tool action is designed to cut at the fastest possible pace while minimizing thermal and mechanical sample damage.
Unique Design
It has a one-of-a-kind design in which the specimen is always shown parallel to the cutting axis. Using the optional microscope will enable site-specific cutting easier by assisting in locating the region of interest. Â A dial indicator will precisely indicate the cutting tool depth. Once the specimen has been sliced, the operation will immediately end.
Contant-Force Stage
The specimen stage uses continuous force to move the material parallel to the cutting tool during the cutting process to generate specimens with consistent diameters.
Autotermination
A low-melting-point polymer is used to attach the specimens to an aluminum specimen plate. Two thumbscrews securely fasten the specimen plate to the specimen container, ensuring electrical connection between the container and the stage. Â An electrical continuity detector determines when the cutting process is complete. Â The cutting tool and ultrasonic transducer assembly are kept at ground voltage. A +0.8 VDC signal is applied to the specimen stage. When contact is achieved between the tool and the specimen plate, continuity is detected and the operation is automatically stopped. Â An override switch allows the user to continue cutting even after continuity is detected. Â When cutting conductive material, a specimen plate with an insulating layer on its surface is used to isolate the specimen from the termination signal.Â
