The Multigrind® CB is not a better 5-axis machine. It is the answer to components where classical kinematics reach their limit. What happens today: accessibility via detours. What is created here: accessibility within the system.

Complexity is not the problem. The workspace is.

Guide vane segments. Shroud components. Large, complex aerospace geometries. Technically manageable—even with 5 axes. And yet a break occurs. Not in the component, but in accessibility. Beyond a certain size, geometries are no longer fully reachable. At least not in a single setup. The result is well known: additional setups. New references. New uncertainties. The grinding strategy adapts to the machine. Not the other way around.

The loss does not occur during grinding

Each additional setup shifts the process: new alignment, new tolerances, new thermal conditions. The error does not arise in the individual step. It arises in between. Between the setups. Between the states. That is where drift occurs. That is where instability arises. That is where costs emerge.

Accessibility becomes a system issue

The Multigrind® CB addresses exactly this point. Not the geometry, but the accessibility. Components become fully reachable again. Without additional process steps. Without detours. The lever is the 6th axis. Not as an additional feature, but as a structural element. It runs interpolated. Simultaneously. Within the process. What emerges is not an extension, but a different logic.

Fewer setups are not a detail. They are the difference.

Components that previously had to be forced into multiple setups can be manufactured in significantly fewer states. A typical case: a guide vane segment is machined in two setups. Not because it becomes easier, but because it becomes accessible. The effect is direct: fewer setups. Fewer references. Fewer sources of error. More precision through fewer interventions.

The real leverage lies at the grinding point

Accessibility alone does not solve the problem. The difference emerges in the process. In classical 5-axis strategies, the grinding point continuously shifts—and with it the conditions. Contact. Cooling. Heat input. Everything changes. And this is exactly where the real problems arise: uneven thermal loads, dimensional deviations, unstable processes.

Constant conditions are not a detail. They are the prerequisite.

The Multigrind® CB stabilizes exactly this point. The grinding contact remains constant. The position remains stable. The cooling conditions remain the same. Not as a setting, but as a result of the kinematics. The effect: uniform heat input, reduced drift, stable dimensional accuracy. The process becomes predictable again.

Precision is not achieved through correction

The biggest mistake in the process is constant adjustment. Readjusting. Compensating. Correcting. The Multigrind® CB takes the opposite approach. One stable state. Throughout the entire machining process. No changing conditions. No new references. Precision does not arise from intervention, but from consistency.

Automation is the consequence

Stability is the prerequisite for automation. Not the goal, but the result. No additional interventions. No new reference systems. Reproducible sequences. The process becomes not only precise, but controllable. The key metric that matters: two setups instead of several. This is not a detail. It is the leverage.

Conclusion: When accessibility becomes the problem, kinematics must follow

Complex aerospace components are not the issue. The limitation of classical kinematics is. The Multigrind® CB shifts exactly this boundary. Not through more movement, but through the right movement. Fewer setups. Constant conditions. Stable process. This is not a feature. It is a different way of manufacturing.
