TEMPLATE FOR CHECKING OF GRINDING OF DRILLS Russian patent published in 1995 - IPC

FIELD: test equipment. SUBSTANCE: base with basing unit is made in form of a rod onto which prisms are fixed. The prisms are mounted for movement and rotation at the rod surface. Rest is made in form of a flat strap with two working surfaces. One surface is made in form of a face being perpendicular to longitudinal axis of the rod. The other one is made in form of edge of wedge disposed in perpendicular to longitudinal axis of the rod and belongs to plane of symmetry of the prisms. Template is provided with angle meter, which has dial made in form of lines applied to side surface of the rest. Indicator coincides with rule of the template has checking element with variable curvature profile. The element is mounted for movement along the surface of the rod and made in form of flexible plate. One end of the plate is fixed rigidly at the rest, and the other one is fixed at the rule. Template may be used at all branches of production where drills are applied, as well in systems of professional education. EFFECT: improved technological capabilities of the template. 5 cl, 7 dwg
