Allied Machine Drill System Provides Enhanced Chip Evacuation

Seco Tools has introduced larger LP09 inserts for its HighFeed 2 cutter bodies to eliminate long face milling cycle times and to ensure process security. The inserts are designed Cutting Inserts for high-feed milling operations in challenging workpieces often found in the mold and die, aerospace, and oil and gas industries.

Extending the existing HighFeed 2 milling family, the new LP09 inserts combine higher insert corner strength with dual cutting edges. The face milling cutter bodies feature reinforced cores and more teeth per diameter for increased feed rates and faster material removal rates. During high-feed milling, the optimized flutes of the cutter bodies are deep hole drilling inserts said to evacuate chips efficiently.

The rectangular shape of the inserts, along with the close-pitched cutter bodies, help to extend tool life beyond that of square inserts. Cutter body pockets ensure consistent and precise insert positioning or seating when indexing, and high-strength screw clamping holds the inserts securely in place.

The company’s positive inserts are available in a full range of chipbreakers, including MD15, M13 and ME08. HighFeed 2 cutter bodies range in size from 1.250" to 4.00" and from 25 to 100 mm.

Double Sided Shoulder Mills Achieve High Surface Quality

Sandvik Coromant introduces two new ceramic insert grades that are capable of performing high-speed, high-security turning operations on components made from demanding HRSA (heat-resistant superalloy) materials. The CC6220 and CC6230 ceramic grades are developed to machine demanding materials where whisker ceramics and SiAlONs fall short. Their ability to handle higher cutting speeds contributes to reduced cost per component, while inherent machining security ensures that quality is not compromised, according to the company. 

The company claims that there is growing demand for aerospace engine parts that can withstand extreme temperatures beyond the capability of those made from Inconel and other high-performance superalloys. Although these powder metallurgic materials can be tailored to handle Surface Milling Inserts substantially higher temperatures, they are more difficult to machine than common HRSAs. CC6220 and CC6230 are said to excel when turning demanding materials in intermediate stage machining. One of the most common applications to benefit is expected to be turbine disc CCGT Insert turning.
