If your production demands maximum concentricity accuracy, stable machining processes, and repeatable quality, Henninger delivers more than just machinery — you gain a true specialist in high-precision manufacturing solutions.
Henninger develops and manufactures center grinding machines, precision tooling, and high-speed spindles entirely in Germany. This decades-long specialization in precision center grinding has established the company as a global technology leader in the field. Customers benefit from sophisticated machine concepts, exceptional durability, and machining solutions capable of operating reliably within micron-level tolerances.
Everything is supplied from a single source: high-performance machinery, precision tools, custom-engineered solutions, test machining, and subcontract machining services. This provides maximum process reliability throughout the entire project — from technical consultation to fully optimized production integration.
When your components require the highest level of precision, experience is not an advantage — it is essential. This is where Henninger excels: decades of engineering expertise, deep technical knowledge, and a commitment to delivering the best possible solution for your manufacturing process.
Center Grinding — Our Core Expertise
Perfect Runout Starts at the Center
Center grinding machines are primarily used wherever maximum concentricity and rotational accuracy are required. The quality of the center hole directly determines how precisely a workpiece rotates between centers. Even the smallest imperfections can cause imbalance, vibration, increased tool wear, or functional issues during operation.
By precision grinding the centers, a highly accurate and stable reference point is created — forming the foundation for perfectly running shafts, spindles, rotors, and other high-precision components. This process is essential for achieving superior runout accuracy, process stability, and long-term machining reliability.
Discover more about the critical role of center grinding and why it remains an indispensable process in modern precision manufacturing and CNC machining.
Custom-Engineered Solutions
Tailored for Your Manufacturing Requirements
Customers from the automotive, aerospace, mechanical engineering, and toolmaking industries come to Henninger not only for machines — but for complete precision engineering solutions. How can shafts, gearbox components, and high-precision parts be ground and aligned with minimal tolerances? Which spindle technology guarantees consistently superior runout performance?
With more than 400 developed tooling variants and state-of-the-art center grinding machines, Henninger sets global standards in product customization and precision engineering flexibility. We believe that runout accuracy below 1 µm and roundness below 0.5 µm are not a coincidence, but the result of advanced engineering, manufacturing expertise, and decades of experience.
That is why we do not simply modify existing products — we develop the right solution from the ground up for your specific application. Discover the unique possibilities Henninger can offer for your precision machining and manufacturing processes.
machining services
Precision from the Source
With the subcontract machining services of Henninger, you receive high-precision components and center machining at the highest industrial standard. Using advanced CNC machining centers and precision grinding technology, we manufacture ready-to-install parts with extremely tight tolerances and exceptional quality consistency.
A key focus of our precision machining services is center grinding as a specialized manufacturing process. Workpieces up to 3000 mm in length, 275 mm clamping diameter, and 1000 kg in weight can be machined efficiently and accurately. By utilizing our own high-precision center grinding machines, we ensure perfectly machined center holes and optimal runout conditions for all subsequent machining operations.
