With excellent thermal and chemical resistance, Ti-NAMITE-A (AlTiN) allows for dry cutting and improvements in performance of carbide. The coating has a high hardness giving ultimate protection against abrasive 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 proprietary 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.

One common misconception is that coated micro tools are often unnecessary because most machines cannot reach sufficient spindle speed to warrant the additional expense of a coated tool. Our testing shows AlTiN coating increases tool life by 250 percent, even when the cutting speed is well below that recommended for uncoated carbide. In other words, coating cost is justifiable, even at low spindle speeds.
