Precision sheet metal is the fabrication of thin metal requiring specific dimensions while holding a tolerance. A tolerance is the range for a dimension. This is annotated on a print. Precision is tolerance in the sheet metal and machining industry. A mundane example would be the required length for a part being 25 +/-.25 inches. The +/-.25 is the tolerance. This means the part can be 24.75-25.25 inches. VIP tolerances can be found in the manufacturing engineering section of our website.
