With excellent thermal and chemical resistance, Ti-NAMITE-A (AlTiN) allows for dry cutting and improve- ments in performance of carbide. The coating has a high hardness giving ultimate protection against abra- sive wear and erosion. Ideal for cast iron, high temperature alloys, steels, and stainless steel applications. Hardness (HV): 3700 Oxidation Temperature: 1100°C / 2010°F Coefficient of Friction: 0.30 Thickness: 1 – 4 Microns (based on tool diameter) KYOCERA SGS PRECISION TOOLS AlTiN COATING PERFORMANCE (LAB RESULTS) SEM photography shows the KSPT propri- etary coating method provides a significant reduction in macro particle deposition on the tool surface, which contributes to NORMAL AlTiN MICRO-TOOL COATING increased performance due to smoother @ 1.06KX MAGNIFICATION chip flow. Another benefit of the KSPT micro-tool coating is a significant reduction in edge rounding due to excessive thick- ness, typical of most normal coatings. KSPT PROPRIETARY AlTiN MICRO-TOOL COATING @ 1.06KX MAGNIFICATION One common misconception is that coated TOOL LIFE COMPARISON micro tools are often unnecessary because 4140 alloy steel / 30 HRc / dry most machines cannot reach sufficient 15000 rpm / 6 ipm / slotting to failure spindle speed to warrant the additional 1/32 4-flute carbide end mill expense of a coated tool. Our testing shows 120 AlTiN coating increases tool life by 250 Usage (Inches) 100 percent, even when the cutting speed is 80 well below that recommended for uncoated 60 carbide. In other words, coating cost is 40 justifiable, even at low spindle speeds. 20 UNCOATED COATED 0 4 www.ksptmicrotools.com
