Our inner grinding spindle – precision that is in every detail
Our inner grinding spindles bring your grinding processes to the point – with uneven precision and stability. They also master the most complex tasks in which conventional solutions fail. Perfect for every challenge – if every millisecond and every micrometer deviation counts.
Internal grinding spindle: You need to know
An inner grinding spindle is the precise centerpiece of each grinding machine, which is responsible for the exact internal grinding of workpieces. It ensures that the grinding tool meets the workpiece with absolute accuracy and processes it in narrow, difficult to access areas – without compromises in precision. Thanks to its refined storage and perfect geometry, it rotates almost freely from vibrations and deviations.
This finely tuned Technology allows constant processing quality, even under the most demanding conditions. In industries where even the smallest errors make the difference, the inner grinding spindle guarantees perfect results in which any tolerance is exactly maintained.

The key to fault-free grinding processes
You wonder why choosing the right inner grinding spindle is so important? Very simple: your production depends on the precision. A faulty spindle quickly leads to inaccurate machining and increased machine shutdowns.
Our inner grinding spindles guarantee constant results, maximum efficiency and a long service life, even with highest requirements. This precision is crucial in medical technology or in mould construction where every micrometer deviation counts.
Advantages of the inner grinding spindle
Maximum precision
Our inner grinding spindles guarantee a round running accuracy of less than 2 μm. This exceptional precision ensures that each workpiece is processed within the narrowest tolerances, ensuring the quality of your products at a constant high level and reducing rework or reject to a minimum.
High speeds
With our spindles you achieve high speeds that speed up your grinding processes without impairing accuracy. This means less time spent in production without cutting off quality – ideal for fast and efficient production.
Low maintenance costs
Our internal grinding spindles are designed for a long service life in continuous operation. Robust materials, sophisticated storage technology and long-lasting lubrication systems significantly reduce maintenance requirements and ensure that your machines run reliably and without frequent downtime.
Easy integration
Whether new construction or Retrofit – our compact inner grinding spindles can be easily integrated into your existing machine environment. This flexibility ensures that you do not have to compromise performance and that your production lines can easily switch to the latest technology.
