Core Selection Logic for High-End Machine Tool Bases (Beds): For heavy cutting,ct gray iron / ductile iron; for ultra-precision, select natural granite; for lightweighting / high damping, select mineral casting (artificial granite). Global standards are primarily bn five major systems: ISO, EN (DIN), ASTM, JIS, and GB/T, focusing on controlling material grades, mechanical properties, residual…

When selecting laboratory granite countertops, the key is to base decisions on four major dimensions: experiment type, precision requirements, chemical environment, load-bearing capacity, and installation conditions. Prioritize highly dense, low-radiation stone with precision machining, and match thickness, grade, sealing, and structural design. Here is the complete selection guide: I. Core Advantages and Applicable ScenariosGranite (especially…
