GEOTOME DUAL has two working zones. On one side: cutting rock samples CUT / PREPARE / THIN. The cutting side can use all diamond discs to a diameter of 250mm. With its manual-movement longitudinal table, it allows you to cut rock and prepare the sample. Once the cube is glued to the thin section, it is possible thin it to a fixed or variable measurement thanks to the mobile or non-mobile vacuum vice which fixes onto the table. On the other side: the grinding of thin sections. GRINDING. The grinding area of GEOTOME DUAL allows you to pre-polish up to 4 thin sections simultaneously. They are held by a vacuum sample rack and are rectified thanks to a 175mm diameter diamond head cup wheel with resinoid, metallic or vitrified binder.
