Edge-hardened Cutting Rules

HP plasma hardened

HP Properties

  • Edge-hardened by special plasma hardening process
  • Highest possible lifetime of the die, due to high cutting edge hardness of ~ 700 HV
    (~ 60 HRC)
  • HP is unique to Martin Miller rules

HP Application

  • For high to extremely high production runs / number of cuts
  • Dust reduction in the cutting process
  • Optimized for tight bends

Special Execution

  • HF Products on request
  • HP+ even harder variant of the HP with ~ 900 HV (~ 67 HRC) edge hardness, on request

 

Through-hardened Cutting Rules

MM through hardened

MM – Properties

  • The same hardness of cutting edge and body
  • Good bendability due to soft and ductile surface layer

MM Application

  • Small to medium size runs / number of cuts
  • Good bending properties
  • All purpose rule (carton, corrugated)
