K1000TTCi is a bus type double-channel CNC system for lathe machine developed by KND company. It adopts 8.4/10.4 inch LCD screen with horizontal/ vertical structure and has 4 profiles totally. System communicates with servo unit in real time through KND serial servo bus (KSSB), which can control feed axes, analog spindle, digit spindle, I/O modules of two channels, etc. Separate control and operation for each channel is available, as well as interactive communication and control between two channels. This system can meet most of application requirements for double-channel lathe control.
