| Abstract: | his paper introduces design characteristics and operating principle of the first domestical size reducing machine which is developed lately. The size reducing forming mechanism and die thrust calculation formula is studied and analysed by means of the main stress method. The experimental results show that the actual die thrust is more 10-15% than the theory one. |
