SINUMERIK 828D Basic – Increased productivity and precision in production

The use of two independently working tools makes 4-axis turning (balance cutting) possible. The new functions include multi-channel functionality with ShopTurn, which among other things allows programs to be synchronized with programSYNC. Shortest programming time for the production of individual parts and small series is guaranteed.

The new software offers the option of running two channels in lathes and grinding machines at the same time. The SINUMERIK CNC control 828D Basic sets standards in all aspects of machining performance. Whether accuracy and speed, whether reducing cycle times or energy efficiency and safety - SINUMERIK sets the pace.
