Spindle holder for precise clamping and secure rounding

Our spindle holders ensure a stable and exact clamping of your Breaking spindles – even under demanding conditions. They ensure precision in the grinding process, extend the service life of your spindle and are also available as a custom production.

What is a spindle holder – and what is it needed for?

Spindle holders are inconspicuous – but essential. Without it no precise clamping, no stable spindle, no repeatable grinding results. You keep dressing spindle exactly where it belongs: free of play, free of tension and precisely aligned. Especially in machines that run in continuous operation for many hours, it depends on every micrometer. A clean spindle holder ensures that your spindle can permanently unfold its power – and will not become a weak point in the process.

Precision from clamping: What distinguishes our spindle holder

Our spindle holders are asked exactly when a spindle is to unfold its full power – permanent, accurate and without disturbing vibrations. They form the solid basis of each successful dressing solution and secure the power transmission as well as the position of the spindle in the process. We rely on low-voltage annealed GG25 casting, fine-machined surfaces and a constructive design that maintains high loads as well as finest tolerances.

The targeted undersize in the half shells ensures reliable, stress-free clamping – even with frequent change. Result: smooth running, reproducible grinding results and a significantly longer service life of the spindles used.

You have these advantages with our spindle holders

Exact clamping without voltage distortion

The half-shells of our spindle holders are deliberately undersized. This secures the spindle without tightening the housing – even in sensitive applications.

Quiet run thanks to minimal tolerances

Due to fine-machined support and clamping surfaces with parallelity accuracies below 0.01 mm, the round running of the spindle remains constant – even with continuous loading.

Less Committee on Process Stability

The low-vibration clamping prevents dimensional deviations in the grinding process and ensures consistent results over many cycle cycles.

Longer spindle and tool stand time

Low micro movements and play-free reception ensure uniform loading of the spindle – the reduced wear noticeably.

Flexible integrated in existing machines

Our holders are also designed for tight installation spaces and can be adapted exactly to your machine geometry – ideal for retrofit or special solutions.

Low maintenance and durable

The robust design of GG25 cast combined with precise manufacturing reduces maintenance costs to a minimum and ensures long-term operational reliability.
