Tooling: frequently asked questions
Which tooling brands does Prella Technologies supply?
Prella supplies three tooling brands. Gerardi, from Italy, makes modular vises, workholding, angle heads and driven tools. CHIA-MO, also from Italy, makes lathe collets, tool holders and accessories. ROMAI, from Germany, makes angular heads, multi-spindle heads, driven tools and high-speed spindles. Prella handles quotes, delivery and support in North America.
Gerardi and ROMAI both make angle heads. Which should I choose?
Gerardi offers catalog angle heads, Classic and Evolution lines, with interchangeable tapers and adjustable models. ROMAI focuses on standard forms plus special and multi-spindle heads built around a specific part or machine, with high-torque options. Send Prella your part, machine and spindle interface and we will recommend the better fit.
Can I get collets for my Swiss-type or multi-spindle lathe?
Yes. CHIA-MO makes collets, feed fingers and guide bushes for single-spindle CNC and Swiss-type lathes such as Star, Tornos and Citizen, and for multi-spindle machines such as Index, Traub and Schütte. Bores can be round, hex, square or special. Most standard items are in stock in Italy.
Does Prella help with setup and service?
Prella is the US partner for these brands. We handle the quote, delivery, start-up and service across North America, and we coordinate technical questions with the manufacturer.
