The dimensions and tolerances, in millimetres, of standard machined plates for press tools.
Values of surface roughness in micrometres. These values of surface roughness apply only to plates with milled edges.
Plates with milled edges: tolerance for dimensions a and b ≤ 630 mm: +0.4/+0.2 mm.
Plates with milled edges: tolerance for dimensions a and b > 630 mm: +0.6/+0.2 mm.
Plates with oxygen-cut edges, water-jet-cut edges: tolerance for dimensions a and b: +4/+1 mm
For high precision plates (grade 2), thickness (t) tolerance is +0.5/+0.3 mm.
