SG-300 Automated specimen grinder

ASTM D4543


Tool designed to provide flat, parallel end-faces when specimen geometry is critical. A variable rate feed mechanism enables the entire specimen to be processed in a single-pass at a preset adjustable speed , thereby producing parallel and flat core loading faces conforming to the ASTM and ISRM specifications. The apparatus comprises a specimen clamping device, a hydraulically operated feed mechanism, a diamond grinding cup wheel, a coolant feeding system and recovery pan. The grinding area is enclosed with a metallic cover encompassing a viewing window. Specimen sizes range from 20-mm to 170-mm in diameter. The unit is an easy-to-use, self-contained machine that surpasses industry standards. Moreover, the high-quality of the genuine diamond-grinding wheel guarantees a perfect, smooth finish.
