Hardening (TPH), a new, highly automated ~n.d fI~ld proven
process developed by TOCCO, merges3 distinctIVe
technologies: Programmed Preheat (AF -I'ow frequency),
High Intensity (AF - hlgh, frequency) and lncramental
Hardening ...AII can be' comprised in a single, compact,
totally integrated manufacturing celli.*
Another TOCCO ,advantage:, The proprietary TPH process
usu~ny uses less than 200 KW rated powers~pplies (AF &
IRIF).So, you don't need an expensi,ve substation" as
r,squired by older design contour hardening systems,
TPH provides gearmakers with:
• Increased strenglth
• R.educed distortion
• Improved metallurgy
• Higher quality
• Lower installation costs
• Reduced operating costs per part
