Professional external grinding with state-of-the-art technology
External c ylindrical grinding is a key manufacturing process for the high-precision machining of rotationally symmetrical components such as shafts, axles and complex turned parts. External cylindrical grinding plays a decisive role, particularly when tight tolerances and perfect surface finishes are required.
We offer both external cylindrical grinding between centers and centerless external cylindrical grinding - two processes that are optimally selected depending on the geometry, material and batch size of the workpiece. Grinding between centers is particularly suitable for components with defined bearings and cylindrical reference points, while the centerless process is ideal for high quantities and continuous processes for rotationally symmetrical workpieces without an axial clamping point.
Our modern system technology enables the exact implementation of complex customer requirements - from prototypes to large series. Thanks to precise process control and continuous quality assurance, we guarantee reproducible results at the highest level. Every component is manufactured with the aim of meeting the exact specifications in terms of dimensional accuracy, roundness and surface quality.
Rely on our expertise in external cylindrical grinding when micrometer precision and reliable process reliability are required.

Frequently asked questions on the subject: External grinding
What are the most important process parameters for external grinding?
The most important process parameters for external grinding are
- Cutting speed (Vc): Dependent on grinding wheel material and material
- Infeed (ae): Determines the removal rate and influences the surface quality
- Feed rate (Vf): Influences the processing time and temperature development
- Grinding wheel hardness and grit type: Determines the service life and material removal rate
- Coolant supply: Reduces heat development and minimizes thermal damage
Why is a special grinding wheel required for external grinding?
For external grinding, the grinding wheels must be adapted to the respective material in order to minimize wear and achieve the desired surface quality. There are different grinding wheels for:
- Hard metals: CBN or diamond grinding wheels
- Steel & stainless steel: corundum or silicon carbide grinding wheels
- Soft materials: Open grain structure for better chip removal
How is concentricity ensured during external grinding?
The concentricity is ensured by various measures:
- Precise clamping technology: Use of centers or chucks with minimal concentricity error
- Balancing the grinding wheel: Reduces vibrations and improves dimensional accuracy
- Correct machine adjustment: Checking guideways and axis movements
- Process monitoring: Use of measuring systems for permanent quality control
What are the advantages of external grinding compared to turning or milling?
External grinding has some specific advantages over other machining processes:
- Higher dimensional accuracy: Achieves tolerances in the range of a few micrometers
- Better surface quality: Ra values down to the range of 0.1 µm possible
- Machining of hardened materials: Ideal for hardened steel and carbides
- Low thermal load: Reduces material changes and crack formation
What are the challenges of external grinding of hardened materials?
Various challenges arise when grinding hardened materials:
- Grinding burn: Surface cracks occur due to excessive thermal stress
- High tool wear: Especially with hard materials such as hardened steel or carbide
- Chip removal: There is a risk of clogging of the grinding wheel with fine grinding chips
- Need for special grinding oils: Cooling lubricants with a high lubricating effect are required
