	There are very strong demands for proton accelera-tors in medium energy range in recent years due to the fast growth of proton therapy and the space science in China. For the applications of proton therapy and pro-ton irradiation, the energy range of proton beam is usually from 200MeV to 250MeV, or even higher for astronavigation [1]. An R&D project for constructing a 230MeV superconducting cyclotron (CYCIAE-230) has been initiated at China Institute of Atomic Energy (CIAE) since Jan 2015. In July of 2016, after the fund-ing was approved by China National Nuclear Corpora-tion (CNNC), the construction project was fully launched. In Dec 2019, the superconducting main magnet and the RF system were transferred to the new-ly built commissioning site. Then, the RF commission-ing, ion source and central region test were performed even during the pandemic in early 2020. In September 2020, after finishing the commissioning tests of all subsystems, the beam was reached the extraction channel but with very low efficiency. Since then, with more efforts on beam diagnostics, the fine tuning of the beam phase and the adjusting of the superconduct-ing coil have been proven to be useful to get higher beam extraction efficiency ~55%. In this paper, the commissioning of the key components, including the main magnet, SC coils, internal ion source and central region, extraction system, etc, as well as the commis-sioning progress of the machine CYCIAE-230 will be presented.
