TOOLS FOR GRINDING WITH GRINDING DEVICE INSIDE surface of the deep holes in the part

摘要

The invention relates to the field of metal processing, in particular to the treatment of the inner surfaces of deep holes in pipes or internal surface polishing method. The technical result in the achievement of which the claimed device consists in providing the possibility of grinding the inner surface of the deep hole in the part with the small-sized Sander at great depths. To achieve the above results used a device for grinding the inner surface of the deep hole in having a rotatable parts comprising inputted inwardly opening post-holder having one end fixed to the holder and at the other end of which is taken by the grinding apparatus as a compact Sander, disposable on a shelf, mounted into the end-holder bar, and the set pressure roller axis along the rotation axis part and at an angle to the pl -plane direction of feed, passing through the axis of rotation of the items, wherein such a way that an optimal contact of the treated surface of the deep hole and the working surface of the grinding belt Sander. Moreover, this device is characterized in that the shelf on which the belt grinder further along the edges provided with disks, one of which is connected to the tool holder, and dimensions are commensurate in diameter with the diameter of the processed deep hole.; 1 bp f-ly
