Benefits of technology

The invention allows for the creation of coolant holes in cutting tips, offering more design freedom and application flexibility. This improves the mechanics of thermal equilibrium during metal cutting and helps with MQL, ensuring the required quantity of lubricant is delivered to the desired area of the tool or work piece. It also eliminates the need to flood the cutting volume with coolant, resulting in savings and a more environmentally friendly approach.

Problems solved by technology

Currently, coolant delivery is limited to carbide or steel shank: from which point we rely on pressure and / or flow rate to flood the cutting volume with coolant.

Embodiment Construction

[0024]In the present description of non-limiting embodiments and in the claims, other than in the operating examples or where otherwise indicated, all numbers expressing quantities or characteristics of ingredients and products, processing conditions, and the like are to be understood as being modified in all instances by the term “about”. Accordingly, unless indicated to the contrary, any numerical parameters set forth in the following description and the attached claims are approximations that may vary depending upon the desired properties one seeks to obtain in the apparatus and methods according to the present disclosure. At the very least, and not as an attempt to limit the application of the doctrine of equivalents to the scope of the claims, each numerical parameter should at least be construed in light of the number of reported significant digits and by applying ordinary rounding techniques.

[0025]Referring to the drawings, there should be an appreciation that the cutting ins...

Abstract

A cutting insert (100,100′) includes a body (102) having a top face (104), a bottom face (106) opposite the top face (104), and at least one flank face (108, 110, 112, 114). A coolant inlet aperture (126), a coolant outlet aperture (132, 134), and an internal coolant passage (128, 130) in fluid communication with the coolant inlet aperture (126) and the coolant outlet aperture (132, 134) are formed using electro-magnetic radiation. The coolant inlet aperture (126) can be formed in the top face (104), the bottom face (106) and / or the flank face (108, 110, 112, 114), and the coolant outlet aperture (132, 134) can be formed in any different face (104, 106, 108, 110, 112, 114). A method of forming the internal coolant passages (128, 130) is described.

Description

RELATED APPLICATIONS[0001]This application is a continuation of, and claims priority to, U.S. patent application Ser. No. 14 / 564,452, filed Dec. 9, 2014, the entirety of which is incorporated herein by reference.FIELD OF THE INVENTION[0002]The invention relates to a cutting insert used for chipforming and material removal operations, as well as a method for making the cutting insert. More specifically, the invention pertains to a cutting insert used for chipforming and material removal operations, as well as a method for making the cutting insert, wherein there is enhanced delivery of coolant adjacent the interface between the cutting edge of the cutting insert and the workpiece (i.e., the cutting edge-chip interface) to diminish excessive heat at the cutting edge-chip interface. The present invention relates to improved rotary tools and improved methods of producing such rotary tools.DESCRIPTION OF RELATED ART[0003]In a chipforming and material removal operation (e.g., a milling op...
