背景技术
数控机床的润滑系统在机床整机中占有十分重要的地位，它不仅具有润滑作用，而且还具有冷却作用，用于减小机床热变形对加工精度的影响。润滑系统的设计、调试和维修保养对保证机床加工精度及延长机床使用寿命等都具有十分重要的意义。油脂润滑不需要润滑设备，工作可靠，不需要经常添加和更换润滑脂，维护方便，但是使用油脂润滑摩擦阻力较大。支承轴承油脂的封入量一般为润滑空间容积的10%，滚珠丝杠螺母副油腊封入量一般为其内部空间容积的1/3。封入的油脂过多，会加剧运动部件的发热。采用油脂润滑时，必须在结构上采取有效的密封措施，以防止因冷却液或润滑油流入而使润滑脂失去功效。数控机床润滑设备系统要求其密封和极压性能有较高的要求，因此有必要研制一种密封极压性能的润滑脂，以满足日益要求严格的数控机床润滑脂设备。
