ISO 6753-1:2005

Overview

ISO 6753-1:2005 - Tools for pressing and moulding - Machined plates - Part 1: Machined plates for press tools specifies the dimensions and tolerances (in millimetres) for machined plates used in press tooling. The standard also provides guidance on designation, gives indications on material and hardness (left to the manufacturer’s initiative), and clarifies surface finish rules for different edge-machining methods.

Key topics and technical requirements

• Dimensions and standard sizes: Includes a table of common plate formats and thicknesses. Typical thicknesses specified include 20, 25, 32, 40, 50, 63, 80 mm, with standardized length × width combinations from small plates (e.g., 160 × 80 mm) up to large sizes (e.g., 1 120 × 800 mm).
• Tolerances: The standard sets tolerances for plate dimensions and thickness. Tolerances vary by:
  • edge machining method (milled vs. oxy-cut/waterjet),
  • plate size, and
  • tolerance grade.
• Machining and designation codes:
  • Edge machining code: 1 = oxy‑cut / waterjet / similar; 2 = milled.
  • Tolerance grade: 1 = normal precision; 2 = high precision.
  • Example designation format (illustrative): Machined plate ISO 6753-1 1 - 1 - 160 × 80 × 20.
• Surface roughness: Surface roughness values in the standard apply only to plates with milled edges.
• Material and hardness: Not strictly prescribed - manufacturers select appropriate material and hardness for intended use.

Applications and users

ISO 6753-1 is practical for:

• Toolmakers and die shops specifying and manufacturing press-tool plates.
• Production engineers and maintenance teams ensuring interchangeability and fit-up in press tooling.
• Procurement and quality assurance professionals creating purchase specifications and inspecting incoming machined plates.
• OEMs and tooling designers standardizing components to reduce lead times and simplify inventory.

Benefits include clearer ordering, improved compatibility between suppliers and toolrooms, consistent quality checks, and reduced rework in press-tool assembly.
