Portable line boring, thread rolling and metal finishing machines in the US
Prella Technologies brings proven Italian machines to American plants, shops and field service teams. For heavy equipment and plant maintenance, SIR Meccanica portable line boring machines and flange facing machines repair bores and faces on site, from 22 mm (0.87 in) up to 6,000 mm (236 in). For production, EVIRT Italia thread rolling machines cold-form threads, splines and ball screws with 100 to 1,500 kN of rolling force. For fabrication, Aceti Macchine belt grinding machines, pipe notchers and plate bevelers prepare and finish tube and plate before and after welding.
One US contact covers the full process. Prella reviews your parts, materials and target output with the manufacturer, recommends the right model and options, and sends a clear quote. We then handle delivery and start-up, followed by service from our office in East Dundee, Illinois. Whether you run a field service fleet, a fastener plant or a fabrication shop, you work with one partner instead of three overseas suppliers.
Machines: frequently asked questions
Which machine brands does Prella offer in the Machines division?
Prella Technologies offers three Italian brands: EVIRT Italia for thread rolling and cold forming machines; SIR Meccanica for portable line boring, welding, facing and turning; and Aceti Macchine for belt grinding, polishing, pipe notching, deburring and beveling machines. All are quoted, delivered and serviced by Prella in North America.
Does Prella install and start up the machines?
Yes. Prella handles the quote, delivery, start-up and service for every machine in this division across North America. We coordinate directly with the manufacturer in Italy, so you have one US contact from the first technical question to after-sales support and spare parts.
How do I choose between on-site machining and shop equipment?
If the part is too large or costly to remove, such as an excavator boom or a vessel flange, a portable SIR Meccanica machine works on it in place. For repeat production or fabrication, EVIRT thread rolling machines and Aceti finishing machines run in your shop. Prella can review your application and recommend the fit.
How do I get a quote?
Use the quote button on any machine page, call +1-847-260-9022 or email info@prellatech.com. Share the part, sizes, material and expected volume. Prella reviews the application with the manufacturer and sends a quote with the recommended model, options and delivery details for your site.
