PROBLEM TO BE SOLVED: To provide a polishing system capable of detecting multilaterally an abnormality related to polishing, and to provide a spot welding system.SOLUTION: A polishing system is constituted so as to include a period determination unit for determining a polishing period which is a period for polishing a weld chip by a polishing part and a non-polishing period which is a period for suspending polishing, based on torque of the polishing part of a dresser for polishing the weld chip, and an abnormality detection unit for detecting an abnormality correlated beforehand with each period. 【課題】研磨に関する異常を多面的に検知することができる研磨システムおよびスポット溶接システムを提供すること。【解決手段】溶接チップを研磨するドレッサーの研磨部のトルクに基づき、研磨部が溶接チップを研磨している期間である研磨期間および研磨していない期間である非研磨期間を判定する期間判定部と、期間のそれぞれにあらかじめ対応付けられた異常を検出する異常検出部とを備えるように研磨システムを構成する。【選択図】図１
