Powerful functions for 5-axis machining
Five-axis machining expands your range of machinable parts and boosts productivity. Other benefits include less rechucking, shorter production times, and fewer sources of error. For complex parts, 5-axis machining is an essential element in your production process.
The TNC 640 from HEIDENHAIN supports the user with numerous practical functions that make 5-axis machining easy and reliable, from programming to part inspection.

Prevent machine damage and downtime
Realistic simulations let you reliably verify the NC program before machining. With a programming station, you can do this from the convenience of an office while leveraging the high realism of our Digital Twin. During setup and production, Dynamic Collision Monitoring prevents collisions during complex 5-axis motion.
Precise machine kinematics model in the control
Shop-friendly calibration cycles ensure consistent machine accuracy. The KinematicsOpt function lets you inspect the accuracy of rotary and swivel axes as well as compensate for any shift in the center of rotation. Any error is automatically accounted for in the kinematics description.
Reliable roughing and finishing processes under consistent cutting conditions
High-efficiency roughing and finishing cycles for tool-friendly machining are essential for productive 5-axis machining. With Optimized Contour Milling (OCM), the control automatically calculates the complex motion needed in trochoidal milling for creating pockets and islands of any shape. The integrated cutting data calculator makes it easy to calculate the optimal cutting values.
