T-11JB CNC Internal Grinding Machines, Chuck Type

High-performance CNC internal grinding machines capable of continuous grinding of multilevel surfaces and external surface grinding, as well as machining of products with an external diameter of up to 350 mm and an internal diameter of up to 170 mm.

T-11JB
The machine is equipped with a dedicated loader and general-purpose robot to allow long periods of fully automatic machining. This machine is also suitable for high-variety small-lot production. During fully automatic machining, the workpiece can be loaded and unloaded while the main spindle is in a swiveled state. The setup time has been significantly reduced.
