FIELD: building industry branches, namely, civilian and industrial building, possibly high-quality treatment of non-solidified surfaces of ferroconcrete products formed of harsh concrete. SUBSTANCE: working organ of smoothing out machine includes body, smoothing disc, drive shaft supporting mechanism in its end. Said mechanism includes driven link of rotary-motion drive having elastic member such as spring rigidly secured to driven link and transmitting rotation to driven splined shaft. Smoothing disc is mounted on end of splined shaft. Said disc performs frictional auto-oscillations in vertical plane (in splined sleeves) due to twisting, tension and compression of spring. EFFECT: enhanced quality of smoothed out surface of products, lowered metal and power consumption. 1 dwg
