Removable disc and cutting tool incorporating same
An apparatus includes a shaft having a first and a second end. A cutter head is mounted on the shaft. An endcap has a removable indicia plate mounted at the second end. The endcap includes an endcap body defining a through-hole extending from a first open end of first inner diameter to a second open end of a second inner diameter less than the first inner diameter. An inner wall surrounds the through-hole defined by the endcap body. An annular channel is in the inner wall receiving at least a portion of a retaining member. A first step is in the inner wall. The first step receives the indicia plate. A second step is in the inner wall. The second step defines mounting through-holes evenly spaced around a center axis of the through-hole. Fasteners extend through mounting holes to secure the endcap to the cutter head.
1 . An apparatus comprising:
a shaft having a first end and a second end opposite the first end;
a high-speed rotary cutter head mounted on the shaft between the first end and the second end; and
an endcap having a removable indicia plate mounted at the second end;
wherein the endcap comprises:
an endcap body defining a through-hole extending from a first open end of a first inner diameter to a second open end of a second inner diameter less than the first inner diameter;
an annular inner wall surrounding the through-hole defined by the endcap body:
an annular channel in the inner wall, the annular channel receiving at least a portion of a retaining member therein;
an annular first step defined in the annular inner wall, the annular first step sized to receive the removable indicia plate thereon; and
an annular second step defined in the annular inner wall, the annular second step defining a plurality of mounting through-holes evenly spaced around a center axis of the through-hole of the endcap; wherein at least two fasteners extending through two mounting holes of the plurality of mounting holes secure the endcap to the high-speed rotary cutter head.
2 . An endcap for a high-speed rotary cutter head mounted on a shaft for mounting to a machine tool, the endcap comprising:
an endcap body comprising:
an annular inner wall surrounding a through-hole defined by the endcap body;
an annular channel in the inner wall;
a retaining member;
a removable indicia plate;
wherein the removable indicia plate is mounted within the through-hole in the endcap body and is removably secured therein by the retaining member;
wherein the annular inner wall defines an annular first step, and wherein the retaining member is seated in the annular channel such that an annular portion of the retaining member is in the annular channel and another annular portion of the retaining member bears against the removable indicia plate to sandwich the removable indicia plate between the retaining member and the annular first step; and
wherein an annular second step is defined in the annular inner wall, the annular second step defining a plurality of mounting through-holes evenly spaced around a center axis of the through-hole of the endcap body; wherein at least two fasteners extending through two mounting holes of the plurality of mounting holes secure the endcap to the high-speed rotary cutter head.
