In a CNC environment, the traveling steady rest is particularly useful for automatic turning cycles on long shafts — the CNC program can manage continuous feed while the steady rest follows the carriage. Without a steady rest on long workpieces, axial deflection causes unplanned taper and increases stress on the spindle.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eIs the steady rest compatible with CK 320, CK 360, and CK 400?\u003c\/summary\u003e\n\u003cp\u003eNo — each steady rest set is specific to the model indicated in the title (CK 400), because the T-slot pitch of the bed and the column diameter vary between the CK 320, CK 360, and CK 400 models. Always check the model of your CNC lathe before purchasing.
