Grinding spindle head DYFJM-180

Product overview
This DYFJM-180(100)20/15A2-F configuration raises maximum speed to 2,500 rpm while retaining a 100 mm internal mounting bore. Its balanced axial and radial static stiffness makes it a versatile spindle for cylindrical grinding, offering a different performance profile than the lower-runout 110 mm journal variant.
