METHOD OF MAGNETIC-ABRASIVE TOOLING OF INTERNAL SURFACES OF HOLLOW NON-MAGNETIZED PARTS LIKE ROTATING BODIES

摘要

Usage: finishing the internal surfaces of the non-magnetic parts such as bodies of rotation. The essence invented the shadows: the item is placed between opposite poles of the magnetic system. Inside parts flux placing the mandrel with a protrusion - of the magnetic field concentrator in the form of a helical surface. Lifting angle helical surface is determined from the ratio tga Vb / Vn, where Vu - the speed of rotation of the mandrel; Vn - its rate of axial movement. Specify the details of the rotation and the rotation and axial movement of the mandrel. With this choice of the angle of lifting the helix direction of the principal vector of the mandrel speed coincides with the screw surface. Grain powder, moving Referring velocity vector in the direction coinciding with the principal vector of the mandrel speed are moved together with the hub protrusion. Excluded breakdowns powder protrusion and entering it into the slots. Increased productivity. 2 yl.
