Kyocera Precision Tools' RFH-Series roughing endmills feature a multiple-edge design and internal coolant that make it the ideal tool for deep slotting (DOC = 2 times diameter) stainless steel and titanium alloys. The unique flutes are designed with serrated, round cutting edges to enhance chip flow.
This reduces the number of defects found in the workpiece that are common when roughing difficult-to-cut material. Creating a great finish eliminates the need for a second finishing tool after roughing. The MEGACOAT HARD coating technology delivers the highest hardness and thermal resistance of Kyocera’s PVD coatings for longer tool life.
Related Glossary Terms
Substances having metallic properties and being composed of two or more chemical elements of which at least one is a metal.
Fluid that reduces temperature buildup at the tool/workpiece interface during machining. Normally takes the form of a liquid such as soluble or chemical mixtures (semisynthetic, synthetic) but can be pressurized air or other gas. Because of water’s ability to absorb great quantities of heat, it is widely used as a coolant and vehicle for various cutting compounds, with the water-to-compound ratio varying with the machining task. See cutting fluid; semisynthetic cutting fluid; soluble-oil cutting fluid; synthetic cutting fluid.
- finishing tool
Tool, belt, wheel or other cutting implement that completes the final, precision machining step/cut on a workpiece. Often takes the form of a grinding, honing, lapping or polishing tool. See roughing cutter.
Grooves and spaces in the body of a tool that permit chip removal from, and cutting-fluid application to, the point of cut.
Hardness is a measure of the resistance of a material to surface indentation or abrasion. There is no absolute scale for hardness. In order to express hardness quantitatively, each type of test has its own scale, which defines hardness. Indentation hardness obtained through static methods is measured by Brinell, Rockwell, Vickers and Knoop tests. Hardness without indentation is measured by a dynamic method, known as the Scleroscope test.
- physical vapor deposition ( PVD)
physical vapor deposition ( PVD)
Tool-coating process performed at low temperature (500° C), compared to chemical vapor deposition (1,000° C). Employs electric field to generate necessary heat for depositing coating on a tool’s surface. See CVD, chemical vapor deposition.
Machining, normally milling, that creates slots, grooves and similar recesses in workpieces, including T-slots and dovetails.
