Balancing Service
SPINDLE SERVICE - FOR BETTER QUALITY
Balancing according to DIN-ISO 1940
If you require small quantities of rotor balancing, do not have the right equipment for the job, or have special rotors, balancing is also possible at the Doischle Spindle Service.
- Tool holders for HSK, ISO, BT, etc.
- axis of spindle
- Rotor, rotor shaft
- Coupling
- Shaft of a grinding machine
- In special machine equipment and spindle test devices, the rotating mass and weight of the rotating body can be up to 20 kg.
ISO 1940 is an international standard for the balancing of rotating rigid bodies. It also specifies methods for determining residual imbalance. G1.0 is a specific balancing grade within the overall standard, according to which the maximum residual imbalance must be within certain limits, independent of the total mass of the rotating body. Grade G1.0 is a general specification range for high-speed precision spindles.
※ Reference: Standard ISO grades of rotating rigid bodies
- G16 – Drive shaft, engine parts, engine crank
- G6.3 – Turbine gears, pulp impellers and armatures for the marine industry
- G2.5 – Gas and steam turbines, turbo compressors, computer memory drums
- G1 – Grinding machine drives, small electric motors, phonograph drives, spindles, precision grinders
- G0.4 – Gyroscope
Why balancing is necessary
All important components of a spindle system require balancing. All rotating spindles for milling, grinding, etc., as well as small or high-precision rotors and rotors that rotate at tens of thousands of revolutions per minute, require precise balancing. In such cases, you can experience the true value of your spindles by using a balancing system with a permissible residual imbalance of micrograms (μg). To achieve these quality standards, you need a highly qualified and expert partner in this field. Precision balancing is a task that requires perfect interaction between man and machine. The engineers at Deutsche Schule not only know the relevant balancing processes, but also know how to optimally use the advanced technology offered by modern balancing systems, thanks to their extensive experience. Here is an example of the cumulative tolerances of all important components of a spindle system: Balance quality of spindle/drive + Balance quality of tool holder + Balance quality of tool = Final cumulative tolerance (must be less than G2.5 for a long operating life of the spindle).
Balancing Type
Rigid rotors are classified into two types of imbalance.
Whether you use precision spindles, rotors, high-speed tools or drive components for the aviation or aerospace industry, we ensure a high level of quality for your high-performance products.
