11、1 數(shù)控機床潤滑系統(tǒng)控制的改進 機床潤滑系統(tǒng)的設(shè)計、調(diào)試和維修保養(yǎng)，對于提高機床加工精度、延長機床使用壽命等都有著十分重要的作用。但是在潤滑系統(tǒng)的電氣控制方面，仍存在以下問題：一是潤滑系統(tǒng)工作狀態(tài)的監(jiān)控。數(shù)控機床控制系統(tǒng)中一般僅設(shè)油箱油面監(jiān)控，以防供油不足，而對潤滑系統(tǒng)易出現(xiàn)的漏油、油路堵塞等現(xiàn)象，不能及時做出反應(yīng)。二是設(shè)置的潤滑循環(huán)和給油時間單一，容易造成浪費。數(shù)控機床在不同的工作狀態(tài)下，需要的潤滑劑量是不一樣的，如在機床暫停階段就比加工階段所需要的潤滑油量要少。針對上述情況，在數(shù)控機床電氣控制。

Such failure concealed strong, and the diagnosis more difficult. Such a failure of the main reasons there are five areas: (1) machine tool unit to be altered or changed. (2)-axis machine tools all the 0.1 bias NULL OFFSET anomaly. (3) axial reverse the gap BACK LASH anomaly. (4) abnormal motor running, electrical and control of the anomaly. (5) mechanic。
