What Weiss Spindeltechnologie does

Weiss Spindeltechnologie is a German manufacturer of precision motorized spindles, headquartered in Maroldsweisach and operating as the Spindle Technology Business Unit of Innomotics GmbH. Founded in 1993, the company designs and produces turning, milling, grinding, and special-motor spindle solutions for machine tool builders and industrial end users across the metalworking sector. Its engineering asset base spans more than 1,000 milling spindle designs and approximately 3,500 customer-specific solutions realized over time, with proprietary offerings including the SMI24 digital interface and Smart Spindle product line, hybrid spindle configurations, milling-turning spindles with integrated B-axis, and spindles designed for robotic machining.

Revenue is generated through three primary streams: (1) hardware sales of new spindles across turning, milling, grinding, and special-motor categories, (2) professional services including over 3,000 repair and service contracts per year on WEISS and third-party spindle units, and (3) exchange/replacement spindle sales from a stock pool with up to 4-hour delivery readiness. Go-to-market is enterprise field sales targeting more than 500 leading mechanical engineering firms and end users, supplemented by a 24/7 service hotline and a global service network of 12 locations covering 193 countries. The SWSS (Siemens WEISS Spindle Service) partnership extends service reach into Siemens' installed base, and participation in major trade fairs such as AMB (Stuttgart) anchors demand generation. Pricing is quote-based with no public list pricing.
