The Restricting Factors on the Limiting Rotary Speed of the Circular Saw

After plenty of researches has been done and several factors were analyzed and discussed, this paper indicates that the low est resonance critical rotary speed depending on the material, structure, size, and interior stress of a circular saw is an important factor in affecting the limiting rotary speed. Based on the analysis of the results, the paper suggests that the available limiting rotary speed of a circular saw should be kept below 50% to 60% of its lowest critical rotation speed.
