The machining industry has an immense demand for increased productivity and efficiency of cutting tools. ACT offers particular advantages to the industry. Coatings for hard milling, tapping and drilling all vary and are application-specific.The coating process is roughly a 2 hour process per coat. ACT puts forth personalized service and quality. Our low overhead keeps prices competitive, while our strategic use of advanced machinery keeps quality high and turnaround time anywhere from 3 to 48 hours.
TiN- Titanium Nitride serves as an excellent universal choice for increasing tool life. TiN increases hardness and has a high oxidation temperature. This coating is bright gold in color with a surface hardness reaching 81 Rc. Titanium Nitride (TiN) is the most common PVD hard coating in use today. TiN has an excellent combonation of performance properties, attractive appearance, and safety (meets FDA requirements for surgical tools and implants as well as food contact applications).
Appearance: Gold
Thickness: 2-4 microns
Hardness: 2800 Vickers
Thermal Stability: 1000 deg. F or 537 deg. C
Lubricity: 0.4 coefficient of friction
TiCN- TiCN offers improved wear resistance to abrasive, adhesive, or difficult-to-machine materials such as, cast iron, aluminum alloys, tool steels, copper, inconel and titanium alloys. This multi-layered coating is best suited for hard work materials over 40 Rc and operations involving interrupted cuts and high shock applications. The addition of carbon adds more hardness and better surface lubricity. TiCN is capable of having a surface hardness reaching 90 Rc.
Appearance: Light to Dark Grey
Thickness: 2-4 microns
Hardness: 3000 Vickers
Thermal Stability: 750 deg. F or 398 deg. C
Lubricity: 0.3 coefficient of friction
TiAIN- This popular coating is recommended for applications where heat resistance and extra hardness is required for abrasive materials. A formed layer of aluminum oxide gives this tool better life in high heat applications. This coating is primarily selected for carbide tooling where little to no coolant is being used. TiAIN has a surface hardness in the upper 80 Rc range with a coefficient of friction less than Titanium Nitride (TiN). TiAIN coating is a high performance coating which excels at the machining of abrasive and difficult-to-machine materials such as cast iron, aluminum alloys, tool steels, and nickel alloys.
Appearance: Dark Purple
Thickness: 2-4 microns
Hardness: 2700 Vickers
Thermal Stability: 1500 deg. F or 815 deg. C
Lubricity: 0.4 coefficient of friction
Also available are multi-layer coatings that chip to the next layer instead of the tooling substrate, providing a further increase in tool life.
