Whirling & Power Screw CNC Machining

High Precision Machining for Worm Shafts, Lead Screws & Power Screws

Euro Gear Industries offers specialized whirling services combined with advanced CNC machining for the production of high precision worm shafts, lead screws, and power screws. Whirling is an advanced high precision machining process that produces superior thread quality with exceptional lead accuracy. Our whirling and CNC machining capabilities enable us to manufacture complex multi-start threads, deep thread profiles, and tight-tolerance power screws that meet the most demanding US and Canadian industry specifications.

The Whirling Process - Advanced CNC Machining

Whirling is a high precision machining process where a ring of cutting inserts rotates around the workpiece while the workpiece slowly rotates in the opposite direction. This unique CNC machining technique produces threads with exceptional surface finish, precise lead accuracy, and consistent quality—ideal for worm gears, ball screws, power screws, and precision lead screws.
