Control

The SINUMERIK 828D is perfectly suited for equipping horizontal and vertical turning centers with one machining channel and up to eight CNC measuring circuits. Apart from the main spindle and the geometry axes (X axis and Z axis), other machine units can be operated as well:

CNC controlled turret
Tailstock axis (with travel to fixed stop)
Driven tools and C axis mode for end face and peripheral surface machining
Y axis (orthogonal or oblique)
Sub-spindle with synchronous spindle function for complete machining of workpieces

With the SINUMERIK 828D you get a CNC system that is customized for the application in lathes and milling machines. CNC, PLC, user interface and axis control for six CNC measuring circuits are all combined within a single compact unit. The control provides comprehensive CNC functions such as support of sub-spindle machining and powerful tool management capability.

The SINUMERIK 828D offers comprehensive turning capabilities for lathes, plus drilling and milling operations for face machining and peripheral surface machining of workpieces. The performance of the controller and the new motion control allow you to achieve mirror finish surfaces with minimum machining time. The SINUMERIK 828D has eliminated all unnecessary functionalities; this is particularly noticeable in the graphical user interface. This means it is optimally suitable for use in the workshop. Operation, programming and maintenance can quickly be mastered with only minimal training requirements.
