End Mills

The Greenleaf Corp. ran a demonstration at its booth during Eastec 2023 showcasing the capabilities of a range of tool, including indexable and solid options.

Walter USA's Bryan Curley, district sales manager of the East North Atlantic, and Timothy Lacey, field service engineer, discuss some of the cutting tool maker's new endmills and other products on display at the company's booth during Eastec 2023. n

The MA230 Advance solid carbide milling cutting is for universal machining of steel, stainless steel, cast iron and high-temperature superalloys (ISO P, M, K and S workpiece groups) at the highest level. The MA230 Advance cutter is for high-performance roughing and finishing and enables reliable milling with an extremely high metal removal rate.

Due to its shorter cutting length, the JS754 Stub end mills provide full cutter engagement along the entire length of the tool. This maximizes cutter edge use, which helps reduce carbide waste for improved efficiency and increased sustainability.

The metric VariMill Chip Splitters feature a design that actively controls chip size resulting in easier chip evacuation in deep cavities. The end mills include five- and seven-flute configurations from 8mm-20mm metric standard diameters. The five-flute tool maximizes performance in steel materials while the seven-flute tool excels in stainless steel and high-temperature alloys.

The H-Carb Series 77 end mills specialize in deep axial trochoidal and high-speed machining applications and are offered in various lengths of cut. The specially designed core and flute design improve rigidity and chip flow while reducing deflection. The seven-flute design allows for superior finishes at higher speed and feed rates versus 5 and 6 flute tools.

One of the main advantages of the new CoroMill Dura aluminum-specific end mills is their versatile performance in all different types of roughing applications, while also offering finishing capabilities," Wikström continues. "Up to 2×D full slot, pocketing, 5–20° ramping, shoulder milling and more — all with the same end mill.

The M936 maximizes the output of machines most customers use, explained Steve Avers, IMCO's Technical Support Manager. With conventional low-horsepower machines, this free cutting action means the M936 cutter can run to the machine's upper capacity limits.

Whether you're using low-horsepower equipment, high-speed machining centers or a 5-axis machine, POW-R-FEED M936 cutters give you the power to get more production out of every machine, every shift, every day.

Endmills tipped with CBN, which is the second hardest material after diamond, are offered in sizes ranging from 6mm down to 0.1mm in diameter, with various configurations, from sharp corner, radius corner, ball, standard neck length and extended neck length. TOWA offers their CBN endmills in multi-flute configurations.

The A Brand AE-VTSS end mill offers the following features & benefits: Positive rake angle which reduces cutting force. High rigidity to improve milling accuracy. New flute form that facilitates excellent chip evacuation. Duarise coating to minimize thermal cracks. Variable leads which enables stable and high efficiency milling.

The A Brand AE-CR-MS-H end mill offers the following features & benefits: Variable index to reduce chattering. Cutting edge geometry for stable machining of high-hardness steels.
