OvalFlex turning tools meet the high demands of aluminum alloy wheel processing

At present, almost all new cars are equipped with aluminum alloy wheels as standard, and the appearance and structure are changing with each passing day. Ceratizit Austria Gesellschaft mbH has developed a modular turning tool called OvalFlex that meets the needs of this wheel manufacturer for suitability, productivity and process reliability. Austria's Alu-Guss is one of the largest manufacturers of aluminum alloy wheels with an annual production capacity of 3 million pieces. The company has successfully applied OvalFlex to production since 2007. Alu-Guss is a subsidiary of the Borbet Group and employs 730 people. Since 1996, it has developed and produced aluminum alloy wheels for Volkswagen, BMW, Mercedes, Opel, General Motors, Porsche and other companies with an annual output of over 100. Ten thousand pieces, but each batch is less than 1 million pieces. This shows that the future development trend of production is small batches and varieties.
The hub blanks are sent to the CNC machine by a conveyor belt, clamped and swiveled at 2000 r/min for machining with OvalFlex tools. Developed specifically for the processing of light metal wheels, the tool is different from a normal round profile turning tool and is oval. Therefore, it saves space and can be processed deeper into the hub. Compared with the ordinary car, the height is unchanged, but the strength is higher, so that it can achieve deeper cutting retention at a faster speed, showing excellent economy.
The connection interface between the knife seat and the cutter head is elliptical, forming four tapered surfaces, which can be freely connected and in surface contact in both radial and axial directions. Due to the high precision connection, almost no further adjustments are required.
OvalFlex features a modular construction with multiple cutter heads that can be adjusted at different angles. This makes it important for aluminum alloy wheel manufacturers to reduce the number of tools and tools required for machining. effect. Sintra has developed a variety of adjustable inserts for OvalFlex tools. The X32 is larger and stronger than a normal blade of the same type. Thanks to the large inclined surface, it can be accurately positioned, which not only absorbs the cutting force better, but also can be effectively used for intermittent cutting operations.  

Silicon Mirror

Precision Optical Flats are ideal for a variety of applications including interferometry, imaging systems, laser applications, optical path folding, and autocollimation. These mirrors are available in a variety of coating and substrate options, along with surface flatness options of λ/10 and λ/20. Fused Silica, is optically clear and features excellent resistance to abrasion and high durability, making it the best choice for applications in harsh environments.

Silicon features a Knoop Hardness of 1150 and low density, making it tougher than germanium substrates and suitable for weight-sensitive applications, respectively. Diamond-Like Carbon (DLC) Coated Silicon Windows are engineered for 3 to 5µm, making them ideal for infrared defense applications such as thermal imaging.
Diamond-Like Carbon (DLC) Coated Silicon Windows provide anti-reflection coating on one surface and a specially designed DLC coating on the other surface, making these windows highly durable and ideal for harsh environments.
