This article is about the main specification of 3-axis robot arms. Firstly, 3-axis robot arms are mainly applied to take out finished products from 50~280T injection molding machines. Its vertical stroke can be customized by customer’s injection machine, from 600~800mm. Its crosswise stroke is from 165~650 mm. Its traverse stroke is about 1150 to 1350. That’s all about stroke info. And then the max load including ceiling fixture is about 3Kg. The dry cycle time is about 6 sec, the take out time is about 1.4 sec. That’s some detailed info about this type of three axis robot arm. These three axis are all driven by AC servo motor. After that, we gonna talk about some consumption of this three axis robot arm, the working pressure is about 5-7 kgf/cm2, the air consumption is 8 nl/cycle, and the power consumption is 3.2 kva. In the end, the net weight of this robot is about 190~245Kg.
