In our Sample Preparation Unit, cutting, grinding, and machining operations for mechanical test specimens are carried out with high precision and strict adherence to relevant standards. After primary cutting, specimens are machined to achieve the exact dimensions and geometries required for tensile, bending, fatigue, and impact testing. Surface grinding using magnetic grinding machines ensures tight dimensional tolerances, smooth finishes, and proper parallelism, providing specimens that fully comply with BS EN, ASTM, and other applicable testing standards.
Metallographic Sectioning and Sample Preparation
For metallographic evaluation, specimens must first be carefully sectioned to isolate the region of interest and to facilitate proper handling during subsequent preparation stages. The selection of the cutting method depends on the material type and its properties. Metallic materials and metal matrix composites are typically separated using abrasive cutting techniques, while brittle materials require precision cutting with diamond wafer blades.
Careful control of the sectioning process is essential to prevent microstructural alteration or surface damage that could lead to inaccurate metallographic interpretation.
