At CIMT2011, exhibitors from the world's machine tool industry have come up with their own "killers" and set their sights on China's "aerospace" market.
China's self-developed C919 large passenger aircraft project has completed the preliminary design, will be transferred to the project development stage, and has received more than 100 orders. With the promulgation of China's "Twelfth Five-Year Plan", the aerospace industry will receive greater support from the state. The market demand continues to expand and policy support continues to deepen. The huge market of China's aerospace industry has shown great attraction to the world.
Tool manufacturers push new ideas
For the aerospace products, a large number of difficult-to-machine materials such as titanium alloys, high-temperature alloys, high-strength steels, composite materials and engineering ceramics are used. Sandvik Coromant, a supplier of metal cutting tools from Sweden, has demonstrated its new CoroPak11.1. New products, including CoroMillPlura, a new end mill for titanium milling, CoroDrill 452 drill for composite machining, CoroDrill 452 drills, and other tooling products for carbon fiber and composite machining. A new range of end mills in the CoroMillPlura family is dedicated to aerospace parts.
Due to the high temperature resistance of the aerospace industry product parts, this puts more stringent technical requirements on the processing of heat resistant alloys. Tool manufacturing giant Walter introduced two new ISO tooling geometries - NMS and NRS troughs - designed for processing superalloys.
At the 2011 spring press conference of Seco Tools, the company's marketing director Wang Wei introduced the hardened end mill JHP770 & JHP780 for efficient machining of titanium alloys and superalloys; and the hardened drill bit FeedMaxC1 & C2 for processing composite materials.
Active participation of the measurement system
The new five-axis heads exhibited by Renishaw in the UK are mainly used for coordinate measuring (CMM) triggering measurements and won the MM “Most Innovative Measurement System†award at the 2010 AMB show in Stuttgart, Germany. Renishaw's REVO five-axis head/probe system has been used by Mecanizados Escribano Precision Engineering to produce complex parts for aerospace and military applications, which reduces workpiece inspection time by 80%, ensuring quality control and inspection ability.
For aerospace products with high requirements on precision and safety, measurement and measurement is a very important part. “Measurement is no small matter†is the best interpretation of aviation products. At this exhibition, various measurement companies also showed their latest detection technologies and solutions as well as applications in the aviation field. Hexagon exhibited three new models at the show: a standard-sized work-type measuring machine, a white light measuring system and an ultra-high-precision measuring system. The ultra-precision measuring system was imported from Leitz, Germany. This product was involved in the manufacture of Shenzhou V. Hexagon will focus on aerospace and other fields.
Machine tool companies show their talents
GF AgieCharmilles from Switzerland has always focused on the aerospace industry, and its high-precision, high-complexity machine tools have met the general needs of customers in the aerospace industry. In this exhibition, GF AgieCharmilles exhibited a series of machine tools, which fully demonstrated the processing of many aerospace parts including titanium alloy impellers. Among them, FORM3000 is equipped with C-axis and A-axis on the spot, and 5-axis linkage processing of closed impellers shows the solution in the field of aerospace engine processing. CUT200 adopts CleanCut power supply, and by optimizing the roughing and finishing strategies, the workpiece metamorphic layer is almost zero during processing, and there is no material or microstructure change, which greatly guarantees the safety of aviation parts. The vertical groove processing of the disc provides technical support.
Italian machine tool manufacturer JOBS also demonstrated its processing technology for composite materials in the aerospace industry. High-performance equipment including LINXCOMPACT, LINXDUO, JOMACH, TARKUS and JOMAX can be used in the aerospace industry. Among them, LINXCOMPACT high-efficiency vertical machining center with double-motorized direct-motor drive can be used for composite cover and structural parts processing, representing the most advanced technology for processing composite materials and new material parts. High-precision drilling and reaming system including dynamic depth control, built-in vacuum system, DUO machine with linear motor drive, dual-axis spindle head with built-in vacuum system with automatic moving dust cover, etc. A lot of applications.
