Dimensioning and Design

A few points have to be considered when dimensioning precision-milled precision profile strips. For precise positioning during milling, it is necessary to place the strip against a lateral guide. The contact side is the reference side for the dimensioning. Other dimensioning variants are possible by arrangement. All the dimensions result from this positioning as described below.

Milling widths (Nb) are dictated by the milling tool. The smallest tolerance is ± 0.02 mm. Position dimension (P) measured from the reference side. Thicknesses are defined by the residual strip thickness.

For cost-effective production and to simplify handling, we recommend that the following points are taken into consideration when designing precision profile strips:

• A cutting burr is produced during milling, depending on the alloy and the milling geometry. A flank angle of ≤ 60°, or alternatively a flank angle of up to 88° and a chamfer or radius ≥ 0.05 mm is necessary at the milling flanks in order to reduce or avoid this burr (see Drawing 1, detail X)!

Further geometries are possible by agreement.
