料简是挤出机的关键零件之一，其质量的好坏直接影响到塑料制品的质量、生产率等。料简内孔的尺寸精度、形状精度和表面光洁度要求很高，且材料强度和硬度高，又是深孔加工。在专业化生产厂大多采用专用机床来完成此加工，而对一般工厂来说，料筒的加工便成为难题。我们改装了 It is one of the key parts of the extruder that the material quality is directly related to the quality and productivity of plastic products. Material Jane hole in the dimensional accuracy, shape accuracy and surface finish demanding, and the material strength and hardness, but also deep hole processing. In specialized production plants, most of them use special machines to complete this processing. For the general factory, the processing of the barrel becomes a problem. We modified it
