我厂T611H大型镗床φ110mm主轴防护罩橡胶密封环,原来采用其他结构橡胶模具制造,不仅脱模和定位困难,而且制造出来的橡胶密封环的φ117主要设计尺寸达不到公差要求,使用中产生密封环与主轴配合公差过大或过小,失去主轴防护罩作用。我们为保证密封环质量,方便脱模,准确定位, I plant T611H large boring machine φ110mm spindle guard rubber seal ring, the original structure of rubber molds used in other structures, not only stripping and positioning difficulties, but also to create the rubber seal ring φ117 main design size of less than tolerance requirements, the use of the resulting seal Ring with the spindle tolerance is too large or too small, the role of the main shaft shield lost. We have to ensure the quality of seal ring, convenient demoulding, accurate positioning,
