I.Material Selection Select materials such as tungsten carbide,high-speed steels(e.g.,SKH9,SKH55,SKH59,M2,M35,M42),and powder-metallurgy high-speed steels(e.g.,ASP23,ASP30,ASP60).These materials ensure high precision and long life in harsh conditions due to their hardness,wear-resistance,and corrosion-resistance.
II.Machining Processes
1. Forging:Ideal for complex,high-precision punches,forging ensures uniform material structure and enhanced mechanical properties.
2. Mechanical Machining:Methods like turning,milling,and grinding suit simple,general-precision punches,offering good accuracy and surface quality.
3. EDM:Suitable for complex,high-precision punches,providing high accuracy,efficiency,and surface quality.
III.Surface Treatment Apply shot peening and nitriding to boost surface hardness,wear-resistance,and fatigue resistance,extending punch life and maintaining precision.
IV.Quality Inspection Use CMM and laser scanners to check punch dimensions,enabling timely correction of manufacturing deviations and ensuring design accuracy.
By optimizing material selection,machining,surface treatment,and quality inspection,high-performance,high-precision punches meeting various industrial needs can be produced.
