Application Date: 2018-8-3 Patent Type: Invention Application The present invention provides a servo press and a lubricant supply method that can reliably supply lubricant between an eccentric shaft and a connecting rod, or between the front end of the connecting rod and a slider connecting part. A servo press (10) includes an eccentric shaft (13), a connecting rod (14), and a slider (11), an eccentric shaft-side sliding surface (22), a connecting rod-side sliding surface (40), an oil supply port (24), and a supply mechanism (30). The oil supply port (24) opens to the eccentric shaft-side sliding surface (22) or the link-side sliding surface (40), and supplies a lubricant between the eccentric shaft-side sliding surface (22) or the link-side sliding surface (40). The supply mechanism (30) supplies the lubricant to the oil supply port (24). An eccentric shaft-side sliding surface (22) is formed on an eccentric shaft (13) that is rotationally driven by a servomotor (18). The oil supply port (24) is formed on a link-side sliding surface (40) of a link (14) that is moved up and down by rotational driving of an eccentric shaft (13).
