Optimal performance

The TNC 620 features optimized motion control, short block processing times, and special control strategies, thus attaining very high machining speeds with exceptional contour accuracy, particularly during 3D contour machining.

Optimized motion control

The ADP function provides effective motion control optimization. ADP dynamically precalculates the contour, adapting the movements based on a jerk-smoothing acceleration limit. Perfect surfaces are attainable even with a highly variable point distribution.

Realistic simulations

Detailed graphical simulations provide a precise and realistic machining preview, revealing ahead of time whether all required program entries are in place, whether machining operations will run smoothly, and whether surfaces will attain the desired quality.

Optimized Contour Milling (OCM)

The OCM option optimizes roughing processes, using special trochoidal milling cycles to machine any countour with high efficiency. Productivity is significantly increased, while tool wear is considerably reduced. The optimal cutting data are determined by an integrated cutting-data calculator.

Component Monitoring

The Component Monitoring option protects machines by monitoring specifically for failure and damage. Continuous load monitoring of the spindle bearing and feed axes reliably detects wear and effectively prevents overloading.
