Influence of Fit Clearance and Tightening Torque on Contact Characteristics of Spindle–Grinding Wheel Flange Interface
Round 1
Reviewer 1 Report
Reviewed article concerns influence of fit clearance and tightening moment on contact characteristics of spindle-grinding wheel flange interface and is write in accordance with generally accepted standards of the scientific works. After careful reading of the submitted text there are some substantive remarks that should be taken into consideration by the Authors to improve reviewed text.
- At the end of the introduction should be clearly and concise given the research gap to create the appropriate lead up for the motivation of the work.
- The novelty of given approach should be emphasized in introduction.
- Presented study widely covers defined scientific problem and with modelling as well as experimental investigations provides proper background for given conclusions, however deeper scientific consideration of obtained results referred to the basic phenomena should be given.
- The strengths and limitations of the obtained results and applied methods should be clearly described.
- Wider description of potential use of presented findings in scientific research as well as in industrial practice should be provided.
- Conclusions should refer to specific values (results of analysis) as well as basic phenomena that cause described results and highlight the novelty and contribution to the state of the knowledge in given area.

Reviewer 2 Report
In the paper an analysis method for the contact stiffness of the spindle-GWF interface was proposed. A series of numerical and experimental studies were conducted. In my opinion, the article concerns a current and important topic. The presented works are innovative, but there are some objectionable elements, so please clarify the following issues:
1. There was no validation of the computational model, which is the essence of this work. Have you investigated the effect of finite element mesh refinement on the results? Or does the lines 211-213 say just that?
2. Experimental research is very interesting, but the method itself is presented in a rather complicated way. Only the final results after conversion are shown in the paper. Maybe it is worth adding a diagram of the measurement procedure? Has an attempt been made to estimate the error of this method?
3. Are static stiffness tests not feasible?

Reviewer 3 Report
The paper deals with spindle and grinding wheel flange (GWF) properties. The authors used the finite element method for the analysis of the contact stiffness of the spindle-GWF interface and investigated the effects of spindle-GWF interface original clearance and tightening torque on the contact pressure, final contact state and contact stiffness of the spindle-GWF interface. Results were experimentally verified. It was found that the final contact state of the spindle GWF changed when the tightening torque increased, the contact pressure and contact stiffness of the spindle-GWF interface are increased by increasing the tightening torque. The paper can serve as theoretical guidance for GWF assembly on gear grinding machines.
