Sugino UC-81A SSV3-1626 Servo Motor Drive Unit

The Sugino UC-81A is a dedicated controller/driver for Sugino’s Selfeeder servo drilling systems, configured to operate the SSV3-1626 servo feed unit (and compatible with ST1 and SSM4). It governs the Selfeeder’s free axis movement and coordinates feed with spindle rotation to deliver automated drilling and tapping cycles. The UC-81A exposes a suite of predefined process patterns for drilling and related operations, including 01 Drilling, 02 High-speed deep-hole drilling (Step feed), 03 Deep-hole drilling (Step feed), 04 Quill pipe drilling (Step feed), 05 Drilling counterboring, 06 Drilling with inching feed, 07 High-speed deep-hole drilling (with inching feed), 08 Deep-hole drilling (with inching feed), 09 Quill pipe drilling (with inching feed), 10 Drilling counterboring (with inching feed), 11 Back chamfering, 12 Quill pipe multi-step drilling (with inching feed), and 13 2-step front/rear chamfering. As part of Sugino’s Selfeeder servo family—the servo-driven feeding solution noted for its compact form, high precision, and rigid performance—the UC-81A enables repeatable, automated drilling and tapping within Selfeeder configurations, delivering reliable cycles for production lines that require consistent hole quality and synchronized feed control.
