The D-bit (after Friedrich Deckel, [1] the brand of the original manufacturer) grinder is a tool bit grinder designed to produce single-lip cutters for pantograph milling machines. Pantographs are a variety of milling machine used to create cavities for the dies used in the molding process ; they are largely obsolete and replaced by CNC ...
Rotating abrasive wheel on a bench grinder. Pedal-powered grinding machine, Russia, 1902. A grinding machine, often shortened to grinder, is any of various power tools or machine tools used for grinding. It is a type of material removal using an abrasive wheel as the cutting tool. [1]
Bryant acquired the precision external centerless grinder line from Van Norman Machine Tool Company in 1972. [4] Bryant's Soviet contracts continued to be controversial that same year. Bryant's sale of 45 precision grinders enabled the USSR to improve missile accuracy and MIRV their ICBMs. Objections to the sale were quashed by Henry Kissinger. [8]
A surface grinder is a machine tool used to provide precision ground surfaces, either to a critical size or for the surface finish. The typical precision of a surface grinder depends on the type and usage, however ±0.002 mm (±0.0001 in) should be achievable on most surface grinders.
Wah Chang Corporation was an American manufacturing company in the metal or alloy industry based in Albany, Oregon in the United States. Since 2014, it has been a business unit of Allegheny Technologies and makes corrosion-resistant metals, such as hafnium, niobium, titanium, vanadium, and zirconium.
Tungsten carbide (chemical formula: WC) is a chemical compound (specifically, a carbide) containing equal parts of tungsten and carbon atoms. In its most basic form, tungsten carbide is a fine gray powder, but it can be pressed and formed into shapes through sintering [7] for use in industrial machinery, engineering facilities, [8] molding blocks, [9] cutting tools, chisels, abrasives, armor ...
Tungsten-halogen lamps are frequently used as a near-infrared light source in Infrared spectroscopy. Halogen lamps were used on the Times Square Ball from 1999 to 2006. However, from 2007 onward, the halogen lamps were replaced with LEDs , due to the much longer lifespan, about ten times longer for LED over incandescent. [ 32 ]
A jig grinder is a machine tool used for grinding complex shapes and holes where the highest degrees of accuracy and finish are required. The jig grinder is very similar to a jig borer , in that the table positioning and spindles are very accurate (far more so than a manual milling machine or lathe ).
