CORCOM Spindles – Core Competence from Swabia
At the heart of the machine tool industry for over 60 years
Since 1961, components have been manufactured in Rottenburg am Neckar that make the construction of high-performance machine tools possible in the first place. Founded as Hüller Rottenburg GmbH, the facility has continued to evolve over the decades and through several changes in ownership, with a clear focus on the development and manufacture of high-quality key components.
Today, CORCOM is an independent business unit of the FFG Group, one of the world’s largest machine tool groups. From its locations in Rottenburg am Neckar and Kecskemét, Hungary, CORCOM supplies both in-house brands such as MAG, Jobs, and Witzig & Frank, as well as external customers in international markets. What sets CORCOM apart from a traditional supplier is its consistent vertical integration. Development, production, and assembly are largely carried out in-house. The modular design principle characterizes the entire product portfolio, ranging from spindles and rotary tables to tool magazines, pallet changers, and fluid cabinets.
The result is sophisticated plug-and-play solutions for demanding manufacturing environments—precisely integrated, technically optimized, and in use worldwide.
What Sets CORCOM Spindles Apart
The focus in Rottenburg is on spindles—specifically, a range of spindles that covers virtually every machining task. The Gen-4 motor spindle is the workhorse of the portfolio: a universal spindle for machining centers designed for milling, drilling, boring, and reaming, featuring a modular design with a standardized interface to all common control systems and in productive use worldwide for over ten years. Whether in the automotive industry, aerospace, or general mechanical engineering, this spindle knows its craft.
For heavy-duty machining requiring high torque, the gear-driven headstock with a selectable gear ratio (1:4 or 1:6) is the ideal solution: robust, designed for heavy-duty machining of steel, cast iron, titanium, and GGG, and easy to maintain—the spindle can be inserted from the front. For turning and milling combinations, turning spindles with synchronous motors are available; for 5-axis machining, swivel milling heads are available that are capable of both high-speed machining of integral components and heavy-duty machining with a clamped axis.
How CORCOM spindles are constructed
CORCOM spindles are not off-the-shelf products. They are developed as part of a sophisticated modular system tailored to machines from the FFG Group and deployed worldwide from Rottenburg. The bearings are optimized for the specific application; Heidenhain measuring systems ensure precise positioning, while synchronous motors minimize heat loss and ensure high power density within the compact installation space. Monitoring sensors are directly integrated into the swivel spindles—not retrofitted.
What this means in practice is that these spindles operate reliably, last a long time, and deliver consistent performance without any major surprises. Anyone who has seen a Gen-4 spindle still delivering the same precision after more than ten years as it did on day one understands why CORCOM is standard equipment in manufacturing facilities around the world.
KERN Full Spindle Service for Your CORCOM Spindles
If a CORCOM spindle fails, the entire machine usually comes to a standstill. Whether it’s a Gen-4 motor spindle, gear spindle head, or turning spindle—at KERN Spindelservice, we repair all types of CORCOM spindles professionally and regardless of the manufacturer: with a complete damage analysis, bearing replacement, inspection of concentricity and shaft geometry, and a final test run under operating conditions.
With over 35 years of experience and more than 16,000 spindles repaired, we are familiar with the typical failure patterns of motor spindles in industrial production and know how to permanently resolve them—not just work around them. Experience shows that a repair by KERN costs 20–30% less than a new spindle, and your spindle will be back in service in 6 to 8 business days. We provide a 24-month warranty on every repair.
