Abstract
A head assembly of a honing tool includes a carrier having a proximal end connectable to a spindle, a distal end, and a plurality of stones. The head assembly also includes a pilot cap connected to the distal end, and defining an end face and a sidewall. A transition surface defined by the pilot cap extends between the end face and the sidewall. The transition surface extends at a first angle forming a first angled relief and then at a second angle forming a second angled relief.
Claims12
A head assembly of a honing tool comprising:
- a carrier including stones and an end;
- and
- a monolithic pilot cap connected to the end and defining an end face, a sidewall axially and radially spaced from the end face, a first relief angled inwardly from the sidewall, and a second relief angled outwardly from the end face and intersecting the first relief, wherein the first and second reliefs have different angles relative to the sidewall, wherein the first relief is oriented at a first oblique angle relative the sidewall, and the second relief is oriented at a second oblique angle relative to the sidewall that is larger than the first oblique angle.
A honing tool comprising;
- a driven spindle;
- and
- a head assembly including
- a carrier having a cylindrical body with a proximal end connectable to the spindle, an annular mounting surface formed on a distal end of the body, and a plurality of slots that each receive a cutting stone, and
- a monolithic pilot cap having a front side defining an end face oriented perpendicularly relative to an axial direction of the head assembly, a sidewall parallel to the axial direction and spaced from the end face in the axial direction, and a backside attached to the mounting surface, the pilot cap further having a first angled relief extending from the sidewall towards the end face at an oblique angle that projects inwardly from the sidewall and a second angled relief extending from the end face to an end of the first angled relief at an oblique angle that projects outwardly from the end face to form a tapered transition surface configured to guide the head assembly into a workpiece, wherein the oblique angle of the first angled relief is smaller than the oblique angle of the second angled relief relative to the sidewall.
