The field problem in Akebono Brake Astra Indonesia is the utilization of more manual tools to achieve product demands. Considering those issues, the development of a modified hardness checking tool from manual operation to automatic operation. For more effectively, it uses automatic operation in time and savings for other manual tools. The automated tool applies the 3-axes system mechanism using Festo linear actuator with the servo motor. The testing capacity of automatic devices is equal to more manual devices. The frame of the auto-checking hardness machine is assessed by applying load variations. This paper provides a comparison of various aluminum frame types based on different tensile strength and cross-sectional area values. The value of displacement and maximum stress depends on the ultimate tensile strength properties and cross-sectional area of the frame. © 2020 The Authors. Published by ELSEVIER B.V.
