Mazak Spindles – Repairs for Machines That Are Put to the Test Every Day
From a Loom to a Global Brand – The History of Mazak
The history of today’s Yamazaki Mazak Corporation began in 1919 in Nagoya, where Sadakichi Yamazaki initially founded a company specializing in weaving machines. After the company began manufacturing machine tools eight years later, the introduction of the MAZAK brand name in 1963 marked the start of a consistent global expansion. This made Mazak the first Japanese machine tool manufacturer to establish its own production facilities abroad. Today, the company—still family-owned and operated by the third generation—operates eleven global plants—including locations in the U.S., the U.K., Singapore, India, and China—as well as a global network of technology centers across all continents.
Mazak has been operating in Germany since 1981. With its headquarters in Göppingen and additional locations in Düsseldorf, Leipzig, and Munich, Yamazaki Mazak Deutschland GmbH serves as the central sales and service organization for the entire DACH region. The company ensures direct, unimpeded access to sales, application engineering, training, and repair services in accordance with German service standards.
What Sets Mazak Machining Centers Apart
Mazak is one of the few machine tool manufacturers worldwide that develops and manufactures its CNC control system entirely in-house. With the MAZATROL platform—now available in the SmoothAi generation with integrated AI support—the company has been setting the standard in control technology for years.
The platform is integrated into all Mazak machines and serves as the foundation for dialog-based programming, intelligent process monitoring, and seamless connectivity within the Mazak iSMART Factory. For users, this means: a uniform operating logic, a consistent data structure, and a seamless system—regardless of the specific machine type. This reduces training requirements, simplifies workflows, and creates transparency throughout the entire manufacturing process.
The machine portfolio is also consistently structured around integrated systems. It ranges from CNC turning centers and vertical machining centers to multitasking machines in the INTEGREX series, as well as laser cutting machines and hybrid solutions incorporating additive manufacturing.
The INTEGREX series, in particular, has made a significant impact for Mazak on the international stage: machines that combine turning, milling, and—depending on the model—gear cutting or grinding in a single setup. The result is significantly reduced setup times, minimized clamping errors, and noticeably higher process reliability.
This is how Mazak spindles are constructed
Mazak designs its spindles as an integral part of the machine’s overall design, not as interchangeable off-the-shelf components. Typical features of a Mazak motor spindle:
- Spindle motor with direct drive or belt drive, depending on the model series
- Precision bearings for high-speed and heavy-duty machining applications
- Integrated tool clamping and release unit
- Cooling via the spindle jacket and, in part, through the bearings
- Connection to the MAZATROL control system for real-time condition monitoring
Since 2018, Mazak has offered the Smooth Ai Spindle, a system that uses AI algorithms to detect chatter vibrations during milling in real time and automatically adjusts the spindle speed to improve surface quality and tool life. This is not a marketing gimmick, but a measurable intervention in the machining process.
KERN Full Spindle Service for Mazak Machines
Mazak machines are designed for high uptime—which makes a spindle failure all the more serious. Companies that have built their manufacturing operations around Mazak feel the impact immediately. Whether due to bearing wear, mechanical impact, or damage caused by coolant ingress: KERN GmbH repairs motor spindles from Mazak machining centers quickly and professionally—with the necessary understanding of system-specific requirements.
A spindle overhaul by KERN is typically 20–30% more cost-effective than purchasing a new spindle from the manufacturer. The turnaround time is 6 to 8 business days, and we provide a 24-month warranty on every overhauled spindle.
