Abstract

PURPOSE:To facilitate replacement of cutting edge and enhance precision in reproductivity of a hot with inserted carbide taps by such a construction that every carbide tip is fastened by bolt individually located by accurate jig blocks made on the basis of the dimensions of hob. CONSTITUTION:The hob body 1 is provided with a mounting hole 2 in its center, a thread at the periphery in its whole length on the basis of the dimensions of hob and a groove 3 for mounting the tip location blocks. In this groove 3, trapezoidal grooves 5 for location of carbide tips are excavated at a certain pitch on the basis of the dimensions of hob. Location blocks 7 are mounted with bolts 8. A tip 9 is mounted by driving a bolt 11 in the female screw 4 through the mounting hole 10. By this constitution, an accurate mounting is secured.
