Industry challenges

Highest true running accuracy meets demanding free-form surfaces

Diamond turning, laser machining, and ultra-precision grinding require exceptional concentricity and true running accuracy. Processing demanding free-form surfaces without interpolation errors challenges conventional motion control systems. Fast setpoint rates are essential to maintain surface geometry and to achieve sub-nanometer precision.

Critical requirements include nanometer surface roughness, precise surfaces for optical applications, and perfect multi-axis synchronization. The combination of extreme accuracy demands and complex surface geometries pushes standard servo systems beyond their limits.

Our solution

Maximum precision and speed with full trajectory flexibility

Triamec's trajectory streaming delivers precalculated moves at up to 50,000 setpoints per second, minimizing interpolation errors to preserve the exact geometry of complex free-form surfaces. This high setpoint rate enables precalculated feedforward currents and synchronized process control.

Combined with 100 kHz position control, this architecture achieves nanometer surface roughness and optical-quality finishes in diamond turning and precision grinding applications.
