Thread rolling machines for US production: threads, splines and ball screws
Thread rolling cold-forms the profile instead of cutting it. The result is a stronger thread with a better surface finish and no chips. EVIRT Italia builds thread rolling machines for every stage of production. MONO machines run standard threads and profiles at short cycle times. PLANAR two-slide machines roll splines, ISO threads and C3 class ball screws. RADIAL three-die machines thread and cold-form tubes, pipe nipples and large hollow parts. Patented auto-pitching and automatic calculation of working parameters cut setup time when you change dies. Optional loaders, robots and feeders turn a single machine into an automated rolling cell.
Prella Technologies supplies EVIRT Italia thread rolling machines and automation to US and Canadian fastener makers, fitting producers and OEMs. We review your part drawing, material and volume with EVIRT and recommend the right series and model. Then we handle the quote, delivery, start-up and service. EVIRT also supports, maintains and retrofits rolling machines from other brands, so Prella can help you keep an existing fleet running while you plan new equipment.
EVIRT Italia: frequently asked questions
What is the difference between MONO, PLANAR and RADIAL machines?
MONO uses one moving slide and two spindles for standard threads and profiles at high output. PLANAR has two independent slides for precision work such as splines and ball screws, with symmetric or asymmetric rolling. RADIAL uses three dies and three pushing heads for hollow parts like tubes and pipe nipples.
Can EVIRT machines roll ball screws?
Yes. EVIRT states the PLANAR series is tested and approved for producing C3 class ball screws in various materials up to HRC 32. The RADIAL series is also validated for ball screws up to C3 class. Ask Prella for a feasibility review of your part drawing and material.
What rolling force and part sizes are available?
Standard machines range from 100 kN (22,480 lbf) to 1,500 kN (337,210 lbf) of rolling force. Workpiece diameters run from 2 mm (0.08 in) on MONO and PLANAR models up to 350 mm (13.78 in) on the RADIAL 150. SPECIAL series FINs machines reach 2,400 kN.
Do you service thread rolling machines from other brands?
EVIRT Italia offers technical support, maintenance and retrofitting, including on rolling machines from other brands. Prella Technologies coordinates this work for customers in North America. Contact us with the machine make, model and the issue, and we will review the options with EVIRT.
