Machine tools are oftenly used in the manufacturing industry. The milling machine is one type of machine tool that is common in the manufacturing industry. With the technology advancement, conventional milling machines were slowly replaced by CNC (Computer Numerical Control) machines. One of the types of CNC milling machine is the Vertical Machining Center (VMC) 500. In the VMC 500 machine, the use are limited due to the limited motion of the spindle axis. Therefore, the idea of a modular design emerged in the form of an attachment that could change the direction of the spindle to horizontal in order to simplify the manufacturing process with the VMC 500 machine that limited to a vertical axis. This VMC 500 horizontal attachment must designed rigidly so that product accuracy is maintained. By analyzing the static and dynamic characteristics, the finite element method is used using ANSYS simulation software. The output obtained is in the total deflection, natural frequency of product, and the frequency response function (FRF) graph of the design product. The static simulation results show that the deflection that occurs in the horizontal attachment spindle is 3.74 ?m in the X-axis direction and -7.16 ?m in the Y-axis direction for a combined load of 866 N. The dynamic simulation results show the FRF graph in which the horizontal attachment design has the greatest dynamic compliance with a frequency of 513.05 Hz in the second shapes mode in the X-axis direction and a frequency of 262.22 Hz in the first mode shapes in the Y-axis and Z-axis directions. . With these data, the safe and ideal operating areas can be identified
