STANKOIMPORT 3K227B internal grinding machine

STANKOIMPORT 3K227B internal grinding machine built in 1986 in the USSR is used for precision grinding of holes during finishing machining. The machine performs machining of holes from 20 to 100 mm in diameter, in order to achieve the appropriate class of surface roughness and the desired shape without any irregularities. The installed spindle of the grinding machine, with a power of 4 kW, processes workpieces with a maximum length of 125 mm at a speed from 140 to 1440 rpm. The total weight of the machine is approximately 4 t.
