我所是气动工具研制单位,在研制气动工具中,经常碰到一些非标准橡胶密封件,如果用制造模具硫化压制来生产,就会周期长,价格贵,影响研制任务的完成。如果用车床来实现这一目的,相对来说又快又省。一、橡胶材料的性质橡胶材料属弹性很强的非金属材料,它具有导热性能差、强度低且含杂质较多,扯断伸长率为≥250％,扯断强度≥90kgf/cm~2,扯断永久变形25％,硬度70～80邵尔A,针对以上性能,在切削过程中就不能象切削金属那样用推挤作用来切割,用推挤作用只能使橡胶材料产生弹性变形而无法进行切 I am a pneumatic tool development unit, in the development of pneumatic tools, often encounter some non-standard rubber seals, if the use of mold curing press to produce, it will cycle long, expensive, affecting the completion of the development task. If you use a lathe to achieve this purpose, relatively fast and save. First, the nature of the rubber material Rubber material is a highly elastic non-metallic materials, it has poor thermal conductivity, low strength and more impurities, elongation at break ≥ 250%, breaking strength ≥ 90kgf / cm ~ 2 , Tear permanent deformation 25%, hardness 70 ~ 80 Shore A, in view of the above performance, in the cutting process can not be like the cutting metal with a push to cut, with the push can only make the rubber material elastic deformation Can not cut
