Walter's CBN Grades Provide High-Quality Surface Finish
Walter’s WBH10C, WBH10 and WBH20 CBN grades are designed for improved turning of hardened steel ranging to 65 HRC. These grades are said to provide a high-quality surface finish with its MW2 wiper geometry as well as longer tool life with its TiAlSiN coating. Inserts with the laser-etched TM-M2 chipbreaker geometry are also available. All inserts are ground for process reliability. These grades are available in both positive and negative inserts and are suitable for both continuous and interrupted cuts.
The company has also introduced the WBS10, a CBN grade for finishing high-temperature superalloys in either continuous or interrupted cuts. It features sharp EM2 microgeometry and superfine grain with a ceramic binder.
Cutting holes by interpolating a face milling cutter may be a better process choice for many rough and even finish boring operations. Software improvements and better cutter designs allow expanding use of the versatile face mill for hole making.
Liquid coolant offers advantages unrelated to temperature. Forced air is the fluid of choice in this shop...but even so, conventional coolant can't be eliminated entirely.
Simple process considerations can increase your productivity in milling titanium alloys.
