About CTI-USA
CTI-USA (Potesta Consulting Group LLC) is the North American sales, engineering and support partner of Capital Tool Industries (CTI), an ISO 9001-certified manufacturer of precision gear cutting tools since 1966, and the North American distributor and service contact for Eifco CNC gear hobbing and power skiving machines. From Hudson, Ohio we supply complete gear cutting solutions: the machine, the hobs and cutters that run on it, and resharpening and recoating for the life of the tool.
CTI controls every step of production in its own facility in Patiala, India, from heat treatment through CNC relief grinding, and inspects every tool on Klingelnberg gear measuring centers. CTI-USA brings those tools to North America with US-based engineering: send us your product prints and we will design the tools to produce them, recommend a tool steel and coating, and quote with a 6–8 weeks lead time.
Materials: M2 · M35 · ASP 2030 / 2052 / 2060 · S290 · S390
Coatings: TiN · TiCN · TiAlN · AlCrN (Alcrona) · Altensa
Tool-life gain from matched coatings: typically 3–8×
Complete gear cutting solutions
Most shops buy the machine from one company, the hobs from another and send regrinds to a third. CTI-USA puts the whole process under one roof, so cycle-time, tooth-form and tool-life questions get one answer.
1. The machine
Eifco CNC gear hobbing machines, 90–630 mm, and E-skive power skiving machines to 500 mm. Sold and supported in North America by CTI-USA; installed by Eifco technicians.
2. The tooling
CTI hobs, shaper cutters, broaches, milling and skiving cutters specified from your prints, in M2 through S390 with TiN through Altensa coatings. Delivered with the machine or on their own.
3. The tool's whole life
Resharpening in our own Hudson, Ohio facility and PVD recoating by Kyocera or Oerlikon Balzers Coating USA, for hobs, shaper cutters and broaches of any make, so every tool delivers its full regrind life at full performance.
4. The engineering
US-based application engineers, free cycle-time estimators and a tool steel and coating selector, and a quote with every recommendation.
