GSK980TDc Lathe CNC system

GSK980TDc CNC turning control system from CNCmakers is a new product based on GSK980TDb,

and its software and hardware are upgraded,with bigger 8.4” LCD screen and more

powerful built-in PLC which controls 5 feeding axes (including C axis), 2 analog spindles,

2ms interpolation in high speed, 0.1 μm control precision, which obviously improve the

efficiency, precision and surface quality of parts processing. New USB interface,

it supports the file operation and program running in flash disk. As the upgraded product

of GSK980TDb, GSK980TDc is the best choice of CNC lathe for the technical upgrading in economical type.
