Cutting tool materials based on aluminum oxide and silicon nitride. Ceramic tools can withstand higher cutting speeds than cemented carbide tools when machining hardened steels, cast irons and high-temperature alloys.
- cubic boron nitride ( CBN)
cubic boron nitride ( CBN)
Crystal manufactured from boron nitride under high pressure and temperature. Used to cut hard-to-machine ferrous and nickel-base materials up to 70 HRC. Second hardest material after diamond. See superabrasive tools.
Rate of change of position of the tool as a whole, relative to the workpiece while cutting.
Machining operation in which material is removed from the workpiece by a powered abrasive wheel, stone, belt, paste, sheet, compound, slurry, etc. Takes various forms: surface grinding (creates flat and/or squared surfaces); cylindrical grinding (for external cylindrical and tapered shapes, fillets, undercuts, etc.); centerless grinding; chamfering; thread and form grinding; tool and cutter grinding; offhand grinding; lapping and polishing (grinding with extremely fine grits to create ultrasmooth surfaces); honing; and disc grinding.
- grinding wheel
Wheel formed from abrasive material mixed in a suitable matrix. Takes a variety of shapes but falls into two basic categories: one that cuts on its periphery, as in reciprocating grinding, and one that cuts on its side or face, as in tool and cutter grinding.
Machining vertical edges of workpieces having irregular contours; normally performed with an endmill in a vertical spindle on a milling machine or with a profiler, following a pattern. See mill, milling machine.
Lach Diamond Inc. offers a grinding wheel with a metal bond for deep grinding – hitherto almost unthinkable. For the first time, newly developed bond variations are available for profiling during the deep grinding of carbide, high-alloyed steel, ceramics and, in a special specification, even unhardened steel.
What was only possible in time-intensive conventional grinding procedures or with several diamond and CBN grinding wheels, is now accomplished with only one profile grinding wheel known as »contour-profiled«, or “one for everything.“
The innovative metal bond allows contour grinding from the solid – and with profile depths of up to 15 mm, e. g. bottom blades or profile blades – there is absolutely no impact on tool life, even at full feed rate.
The result: Repeatable precision profile cuts in mass production. The advantage is obvious: Significant reductions to a fraction of the original total cost.
