SG-300 Automated specimen grinder

ASTM D4543


This tool is designed to achieve precise and flat end-faces when the geometry of the specimen is of utmost importance. It employs a variable-rate feed mechanism that allows the entire specimen to be processed in a single pass at an adjustable speed, resulting in end-faces that are both parallel and flat, meeting the specifications outlined by ASTM and ISRM. The equipment consists of a specimen clamping device, a hydraulically operated feed mechanism, a diamond grinding cup wheel, a coolant delivery system, and a collection pan for debris. The grinding process is enclosed within a metallic cover that includes a viewing window for observation. Specimens ranging in diameter from 20 mm to 170 mm can be accommodated. This unit is user-friendly and self-contained, surpassing industry standards. Furthermore, the use of a high-quality, genuine diamond-grinding wheel ensures a flawless and smooth finish.
