Problems solved by technology

This arrangement is disadvantageous because it requires additional equipment and is difficult to use in applications involving small tools or workpieces
It is also largely limited to turning applications where the tool does not rotate, and is difficult or impossible to use in applications such as milling operations

Embodiment Construction

[0022] However, EP2946857A1 only provides a fluid passage through the anvil in a straight line. Passages with linear configurations limit the options available for providing fluid through the cutting edge. For example, where the anvil is secured to the tool holder by a bolt or other structure extending through a hole in the anvil, the hole may not allow access to be provided along a straight line. Forming the passageway that travels around the hole may require several manufacturing steps, such as previous drilling and / or blind plugging operations, thereby increasing the cost of the cutting insert.

[0023] in this patent application Figure 1-4 shown for Figure 5-8 An anvil 21 of a cutting tool 23 of the type shown in FIG. Figure 5-8 The cutting tool 23 shown in is a turning tool, however, the invention is not limited to turning tools and may be applied to other tools using anvils (also known as tool shims), such as rotary tools such as milling tools. For example, as in ...

Abstract

An anvil (21, 21', 21") for a cutting tool (23) includes an anvil body (55). A curved passage (57, 57', 57") extends from an inlet opening (59, 59', 59") in the anvil body (55) to an outlet opening (61, 61', 61a", 61b") in the anvil body. The anvil body (55) can be made by an additive manufacturing process.

Description

technical field [0001] The present invention relates generally to anvils for cutting tools, and more particularly to such anvils having fluid passages therein. Background technique [0002] Cutting tools used in modern metal cutting and other machining operations typically include a tool holder with replaceable cutting inserts. Cutting inserts are usually made of a much harder material than the tool holder, such as cemented carbide. The cutting inserts are usually clamped in recesses provided in the tool holder for the cutting inserts. Typically, an anvil (sometimes called a backing plate) is disposed in the recess, between the bottom surface of the recess and the bottom surface of the cutting insert. One purpose of providing the anvil is to position the cutting edge of the cutting insert relative to the tool holder in a desired manner. [0003] Because of the high temperatures generated during cutting operations, it is often desirable to provide cooling and / or lubricatin...
