description The invention relates to a multiple-spindle machine for oversmoothing the internal cylinder-shaped surfaces, employed in machinery building. According to the invention, the machine comprises a base plate (14) whereon four guide columns (5) rest. The base plate (14) is mounted on the table of a drilling machine, the rotary motion being transmitted from a main shaft (1), by means of a spindle (2) to a multiple-spindle head with four ends (A) whereon some honing heads (29) are mounted by means of some cardan drives (31) ensuring their plane mobility. The radial displacement of the abrasive bars necessary both for the size adjustment and for reaching the pressure necessary for abrasion is accomplished by the rotation of a hand wheel (30). The multi-spindle head (A) comprises two half-housings (38) and (35), respectively, wherein some spindles (39 and 40) are mounted by means of some roller bearings (32). Invenţia se referă la o maşină multiax, pentru supranetezirea suprafeţelor cilindrice, interioare, utilizată în construcţia de maşini. Maşina conform invenţiei este alcătuită dintr-o placă de bază (14), pe care se sprijină patru coloane de ghidare (5). Placa de bază (14) se montează pe masa unei maşini de găurit, mişcarea de rotaţie transmiţându-se de la un arbore principal (1), prin intermediul unui ax (2), la un cap multiax cu patru ieşiri (A), pe care se montează nişte capete de honuit (29), prin nişte transmisii cardanice (31), ce le asigură mobilitatea în plan. Deplasarea radială a barelor abrazive, pentru reglarea la cotă, cât şi pentru a realiza presiunea necesară abrazării, se realizează prin rotirea unei roţi de mână (30). Capul multiax (A) este alcătuit din două semicarcase (38), respectiv (35), în care se montează nişte axe (39 şi 40) prin intermediul unor lagăre de rostogolire (32).
