Precision grinding also called calibrating is the use of a widebelt to reduce the thickness of a component to a fixed dimension. This often requires a slow conveyor speed or a reciprocating table with high horsepower per inch of sanding belt, hard sanding rollers, high abrasive belt speeds and coarse grit abrasive belts. The 81 series of Timesavers can remove material up to 0.02 mm.
Milling with a cutting tool is the fastest and least expensive way to calibrate, but the finish is often too rough. Stone grinding provides an excellent finish, but is slow and expensive. Precision grind with a widebelt machine typically has a cost closer to milling but a finish closer to stone grinding, making it an excellent alternative.
This process removes the exterior oxide layer/skin and grinds the material much like a surface grinder – but much faster, with less energy, over the full width, only using a wide belt abrasive. All this resulting in low operational costs. Timesavers will run samples to demonstrate results on your product.
