The Multigrind® CA is not the more precise grinding center. It is the platform for components that can no longer be broken down into individual processes. What applies today is: “Theoretically possible.” What is created here: consistently achievable. Maximum geometric freedom. Including internal gearing. On a single platform. In one clamping.

Complexity is not the problem. The process chain is.

Internal gearing. Helical external gearing. Worm profile. Curvic coupling. Cylindrical, non-cylindrical, freeform. Technically, all of this is manageable. Has been for years. And this is exactly where the misconception lies. The challenge is not the geometry. It lies in how it is handled. Complex components are not consolidated in the market. They are split up. Across machines. Across setups. Across processes.

What emerges is not machining. It is a process chain. With handovers. With coordination. With friction. Grinding time plays only a minor role here. It was never the bottleneck. The effort arises in between. Between the machines. Between the setups. Between the process steps. That is exactly where time and stability are lost. And that is exactly where the costs arise. This is where the Multigrind® CA comes in. Not at the geometry level. But at the system level. Multiple processes become one. Multiple setups become one.

One machine. One setup. One sequence. Not faster grinding. But less system. Around 30 percent less total effort. Not optimized. Reduced. Not because grinding is faster. But because less happens.

Internal gearing: Not “also possible”. But integrated.

Internal gearing is often a separate process. Not out of technical necessity.
But due to system constraints. The Multigrind® CA eliminates this separation.  Internal gear grinding head. Integrated into the tool changer. Spindle change in around 35 seconds. No retooling. Internal gearing is no longer a special case. It is part of the system.

Profile freedom instead of process limits

The limitation is not in the geometry. It lies in the process logic. Fixed cycles. Predefined sequences. Limited degrees of freedom. With the Multigrind® CA, this relationship shifts. Geometries are imported via DXF. Contours are calculated.

Possible are:

• Internal gearing
• Spiral gearing
• Special profiles
• Modifications
• Free non-cylindrical geometries

The geometry defines. Not the process.

The real leap in precision

And this is exactly where the real leap in precision occurs. Precision is not created in the profile. It is created in the relationship between surfaces. Every setup creates a new reference. And every reference creates deviation. It adds up. Rule of thumb: one to three micrometers per re-clamping. The Multigrind® CA breaks this chain. No new reference. No shift. No accumulation. Precision is preserved.

Automation: Stability over speed

This is not about cycle time. It is about controllability.

• less manual intervention
• no re-clamping errors
• reproducible quality
• technically feasible unmanned operation

Automation is the prerequisite for stable processes. The metric that matters. Four machines become one. Four setups become one. That is the real lever.

Where the limit lies

If extreme accuracies in the sub-micrometer range are required, the integrated measurement technology reaches its physical limit. Otherwise, the rule applies: if the component fits into the machine, it becomes controllable.

The Multigrind® CA is not a solution for a defined task. It is the platform for tasks that are yet to emerge. If it is not clear today what will be manufactured tomorrow, this is exactly where the necessary freedom is created.

Conclusion: Complexity is no longer distributed

Complex components are not the problem. How they are handled is. This does not create an additional process. This creates a system. One machine. One setup. One sequence. This is not a detail. This is a different logic.
