Spindle repair is more economical than replacement if the basic structure of the spindle is intact. Damage to bearings, seals or clamping systems can often be repaired without the need for a new spindle. This saves you costs and reduces long delivery times.

After a thorough analysis, we decide whether a spindle repair is the better solution. The original performance is restored through the use of high-quality spare parts and precise spindle repairs. A professional spindle repair extends the service life and ensures reliable production processes.

The main spindle is the central element of a machine tool and determines the precision and performance of the machining process. It is driven by a powerful drive unit consisting of either an electric motor or a mechanical transmission. Power is transmitted directly or via belts and clutches to transfer torque and speed optimally to the tool. The bearing of the main spindle is crucial for high concentricity. High-precision roller or plain bearings minimize vibrations and ensure a long service life. The tool is clamped via a precise tool holder, which enables quick and safe tool changes. Efficient cooling and lubrication prevent overheating and ensure thermal stability. Integrated sensors and controls monitor vibration, speed and temperature to optimize operation. A well-tuned main spindle increases machining quality, reduces wear and increases machine productivity.

The Main spindle is used in many machines. It is the component for the rotary movement and determines the precision of the machining process. Milling machines, lathes and grinding machines use a Main spindle to machine workpieces precisely.

There are different types of spindles depending on the task. A Motor spindle has the drive directly integrated, while a gear spindle transmits the torque via a gearbox.

Choosing the right Main spindle depends on the speed, precision and material. High-quality spindles increase efficiency, reduce wear and ensure precise machining results in industrial production.

As an experienced manufacturer, we develop durable main spindles for a wide range of machines and requirements. Customers worldwide trust us as a reliable supplier of high-performance spindle systems.

The Main spindle must be able to withstand extreme mechanical and thermal loads. Materials with high strength, low thermal expansion and high wear resistance are crucial. As an experienced manufacturer, we rely on hardened bearing steels such as 100Cr6, which offer high hardness and fatigue resistance. These steels minimize plastic deformation under high loads and ensure precise concentricity.

High-performance motor spindles often use alloyed tool steels such as X40CrMoV5-1, which achieve high toughness and thermal stability through special heat treatment. Titanium alloys such as Ti-6Al-4V are a proven material for tasks with particularly high speeds and low inertia. They combine low weight with high tensile strength and reduce dynamic deformation.

Ceramic bearings made of silicon nitride (Si₃N₄) are used in high-precision applications. They offer low thermal expansion, high rigidity and excellent wear resistance. As a leading supplier, we develop customized main spindles for drive spindles and gear spindles for maximum service life and efficiency.

The main spindle is subject to strict quality tests to ensure maximum precision and safety. As an experienced manufacturer, we rely on certified test procedures in accordance with DIN EN ISO 9001 and VDMA 34160. Each component is tested for concentricity, balancing quality in accordance with ISO 1940-1 and thermal stability. This is how we ensure that every main spindle is reliable and durable.

Quality assurance includes vibration analysis in accordance with DIN ISO 10816, which detects imbalances and minimizes wear. Load tests check operational reliability under real conditions in order to maximize the service life of the main spindle. Whether motor spindle, drive spindle or gear spindle, all models meet the highest industry standards.

In addition, non-destructive material testing is carried out in accordance with ISO 9934-1 and hardness testing in accordance with ISO 6508. As a reliable supplier, we guarantee main spindles that meet the highest standards and offer maximum performance in demanding production environments.
