Abstract

A support block adapted for attachment to a surface of a rotatable driving member of a cutting tool machine and adapted for receiving a cutting tool includes a cold formed support block body that includes an axial rearward end having a mounting portion for attachment to the surface of the rotatable driving member and an axial forward end having a front surface. The support block also includes a bore defined by the front surface that is configured for receiving the cutting tool. A method of making the support block is also provided.

First claim

What is claimed is:

1 . A method of making a support block adapted for attachment to a surface of a rotatable driving member of a cutting tool machine and adapted for receiving a cutting tool, the method comprising:
providing a stock material; cold forming the stock material to make the support block to include an axial rearward end having a mounting portion for attachment to the surface of the rotatable driving member; cold forming the stock material to make the support block to also include an axial forward end having a front surface; and forming a bore in the front surface that is configured for receiving the cutting tool.

2 . The method of claim 1 , further including cold forming the stock material to make the support block such that the axial rearward end also includes a chamfer attachment area adjacent at least a portion of a perimeter of the mounting portion.

3 . The method of claim 2 , further including cold forming the stock material to make the support block such that the axial rearward end also includes a bottom surface adjacent the mounting portion.

4 . The method of claim 3 , wherein the front surface is generally planar and the bottom surface is generally planar, the front surface and the bottom surface being generally opposed.

5 . The method of claim 3 , further including cold forming the stock material to make the support block such that the axial forward end also includes a sloped surface adjacent the front surface, wherein the sloped surface is generally opposed to the mounting portion and the sloped surface slopes away from the front surface and toward the axial rearward end.

6 . The method of claim 3 , further including providing the bore to extend from the front surface to the bottom surface.

7 . The method of claim 1 , wherein the bore is formed subsequent to the cold forming the stock material to make the support block.

8 . A method of making a support block adapted for attachment to a surface of a rotatable driving member of a cutting tool machine and adapted for receiving a cutting tool, the method comprising:
providing a stock material; and cold forming the stock material to make the support block.

9 . The method of claim 8 , including cold forming the stock material to make the support block to include an axial rearward end having a mounting portion for attachment to the surface of the rotatable driving member.

10 . The method of claim 9 , further including cold forming the stock material to make the support block such that the axial rearward end includes a chamfer attachment area adjacent at least a portion of a perimeter of the mounting portion.

11 . The method of claim 10 , further including cold forming the stock material to make the support block such that the axial rearward end also includes a bottom surface adjacent the mounting portion.

12 . The method of claim 11 , further including cold forming the stock material to make the support block to also include an axial forward end having a front surface generally opposed to the bottom surface.

13 . The method of claim 12 , wherein the front surface is generally planar and the bottom surface is generally planar.

14 . The method of claim 12 , further including cold forming the stock material to make the support block such that the axial forward end also includes a sloped surface adjacent the front surface, wherein the sloped surface is generally opposed to the mounting portion and the sloped surface slopes away from the front surface and toward the axial rearward end.

15 . The method of claim 12 , further including providing a bore in the front surface that is configured for receiving the cutting tool.

16 . The method of claim 15 , further including providing the bore to extend from the front surface to the bottom surface.

17 . The method of claim 15 , wherein the bore is formed subsequent to the cold forming the stock material to make the support block.

18 . A support block adapted for attachment to a surface of a rotatable driving member of a cutting tool machine and adapted for receiving a cutting tool, the support block comprising:
a cold formed support block body that includes:
an axial rearward end having a mounting portion for attachment to the surface of the rotatable driving member;
an axial forward end having a front surface; and
a bore defined by the front surface that is configured for receiving the cutting tool.

19 . The support block of claim 18 , wherein the cold formed support block body further includes the axial rearward end also having a bottom surface adjacent the mounting portion.

20 . The support block of claim 18 , wherein the bore extends through the cold formed support block body from the front surface to the bottom surface.
