The optimal products for your grinding application
Grinding applications have a special position in the field of machine tools. Internal grinding applications, for example, require sensorless operation of asynchronous and synchronous spindles up to 250,000 rpm.
The motor heating, however, must be kept very low to avoid damaging the sensitive materials and to ensure high machining quality. Another important factor is the flexibility of the machine: Simple and quick exchange of the grinding spindles is essential. For this purpose, the frequency converter should allow storing several motor parameter sets.
In addition, customers often demand special functions like a high-dynamic active load detection. Frequency converters by SIEB & MEYER can fulfill all these requirements and more.
