4. 620 reaches the required cutting speeds by digitally controlling spindle speeds up to 60000 min High contour accuracy The TNC 620 dynamically calculates the contour in advance This enables it to adapt the axis velocities to the contour transitions It controls the axes with special algorithms that ensure path control with the required limits to velocity and acceleration Special filters specifically suppress machine specific natural vibration The desired accuracy and a very high surface quality are attained Thanks to the short block processing time of 1 5 ms even highly accurate contours with very high resolution are not a problem Fast machining at specified accuracy You as user specify the accuracy of the machined contour apart from the NC program You simply enter in the control through a cycle the maximum permissible deviations from the ideal contour The TNC 620 automatically adapts the machining to the tolerance that you define No contour damage occurs with this method High availability In the uniformly digital control design of the TNC 620 all components are connected to each other via purely digital interfaces The control components are connected via HSC HEIDENHAIN Serial Controller Interface the real time protocol from HEIDENHAIN for Fast Ethernet and the encoders are connected via EnDat 2 2 the bidirectional interface from HEIDENHAIN This achieves a high degree of availability for the entire

Minimize setup times Ihe INC 620 makes setup easy Before you can begin machining you must first clamp the tool and set up the machine find the position and orient the workpiece on the machine and set the workpiece reference point This is a time consuming but indispensable procedure After all any error directly reduces the machining accuracy Particularly in small and medium sized production runs as well as for very large workpieces setup times become quite a significant factor The TNC 620 features application oriented real world setup functions They support the user help to reduce non productive time and make overnight unattended production possible Together with the touch probes the TNC 620 offers numerous probing cycles for automatic alignment of the workpieces presetting and measurement of the workpiece and the tool 18 Delicate manual traverse For setup you can use the direction keys to move the machine axes manually or in incremental jog A simpler and more reliable way however is to use the electronic handwheels from HEIDENHAIN see page 35 Particularly with the portable handwheels you are always close to the action enjoy a close up view of the setup process and can control the infeed responsively and precisely Workpiece alignment option 17 With HEIDENHAIN touch probes see page 36 and the probing functions of the TNC 620 you can forgo any tedious manual alignment of the workpi
