Solving punch breakage problems
Parts I, II, and III
This series of articles investigates the many causes of premature punch breakage in stamping operations.
Editor’s Note: Part I discusses typical causes of premature failure. Part II covers the roles of cutting shear and retainers. Part III discusses how tool steel selection, press deflection, and heat from processes such as EDM and grinding affect the likelihood of punch breakage.
STAMPING Journal is the only industrial publication dedicated solely to serving the needs of the metal stamping market. In 1987 the American Metal Stamping Association broadened its horizons and renamed itself and its publication, known then as Metal Stamping.
