A nanocomposite coating that significantly extends tool life.

EXAIR's 1/4 NPT internal mix 360° hollow circular pattern atomizing spray nozzle atomizes fluid and sprays away from the nozzle in all directions. These nozzles are ideal where a smooth, even coating is needed on the inside diameter of a pipe or similar ductwork.

Brush-on Metal Blackeners

Birchwood Technologies three brush-on metal blackeners—Presto Black BST4, Antique Black M24, and Aluma Black A14—are now available in smaller, quart sized (32 oz.) bottles for easier application and handling, at a new lower price point.

Drilling Ductile

Some coatings, such as TiAlN, enable dry machining when drill ductile cast iron, but coolant is desirable to help evacuate the material's small, curled chips. Flood coolant can be appropriate for holes less than 1.5 to 2 diameters deep, according to Bob Jennings, product manager for Ingersoll Cutting Tools, Rockford, Ill. Jennings noted that the toolmaker offers standard Qwik-Twist replaceable-point drills to drill up to 8 diameters deep.

Powdered metallurgy

Watch a video presentation from Seco Tools LLC about the tools and techniques suggested for machining powdered metallurgy. The company reports that inserts with Seco Tool’s Duratomic CVD aluminum-oxide coating can work well for P/M components. The Duratomic technology promotes growth of coating crystals in certain crystallographic directions to improve coating properties.

Productivity Improvements Resulting from Coating Texturing

Don Graham, manager of turning products and education services at Seco Tools Inc., Troy, Mich., discussed "Productivity Improvements Resulting from Coating Texturing" during the Fast Track Seminar series hosted at the Cutting Tool Engineering booth during IMTS 2010.

PVD Coating

Platit Inc. recently hosted an open house in Libertyville, Ill., where the Switzerland-based toolcoating company presented cutting-tool and wear-part coating machines based on plasma-generating physical vapor deposition technology. The animation here offers an "insider's" view of the company's coating equipment.

Hardide Coatings opens new U.S. production facility

Hardide Coatings Inc., a U.K.-based provider of advanced surface coating technology, recently opened a new production facility in Martinsville, Va. The $7 million expansion, which began a year ago, allows Hardide to expand its production operations to North America.

P6005-WKK45C point drill insert

In a news release issued Jan. 16, Walter USA LLC, Waukesha, Wis., unveiled its P6005-WKK45C point drill insert that reportedly brings new levels of performance and cost effectiveness to drilling cast materials (ISO K) as well as other materials. The P6005-WKK45C insert design features a new high-performance geometry for maximum productivity in cast iron materials, and 110° prismatic seat for minimal run-out and stable positioning.

No. 862 Gas-heated Furnace

The Grieve Corp., Round Lake, Ill., recently announced that its 2000°F gas-heated furnace—No. 862—used for preheating molds includes 750,000 BTU/HR installed in four modulating natural gas burners with a floor-mounted combustion air blower. Workspace dimensions are 36" wide x 48" deep x 36" high.
