The quality and process level of graphite for EDM
'High Temperature Graphite Material', the company's product samples Ben, 2002.1.06. [11] Shanghai Carpeng Roland Chemical Equipment Co. Table 6 Models and performance of graphite used by EDM of Roland Carbon Company of France 3. 2. In the early 1990s, Roland acquired the North American Carbon S.1.
A large isostatic graphite electrode suppliers with a working cylinder inner diameter of φ900 × 2000mm. Table 4 Application Recommendations for Graphite Products for EDM in SGL, Germany 2. It is welded with angle steel for every 250 mm in the height direction to prevent deformation, and the service life is 10-12 times. As a result, it has achieved relatively good results, and the specific performance is as follows: 2.2 The process and equipment are the earliest., Ltd., 'Ten Years' History', 'Comprehensive Corrosion Control', 2008, (4): 4-5 [12] Roland Group, France,
'Specification of Carbon Products for Photovoltaic Products', 2009.09. It claims to have developed isostatic graphite successfully in 1962 and is the world's first production Graphite pressing enterprises have rich production experience., Ltd. In addition, an extra-large isostatic press produced by Sichuan Chuanxi Machinery Factory, Sichuan, China was installed in the newly-built French Roland Graphite (Chongqing) Co.2 The granularity of the material is getting finer and finer. In addition, in order to meet the development of the EDM industry and improve the competitiveness of its own market, SGL has been continuously improving the traditional graphite products for EDM for a long time, while focusing more on the development of new products and new technologies.
Overview of the Development of Special Graphite of the German SGL Group', ' Electric Carbon, 2002, (1): 7-17 [3] SGL Carbon Group, 'Special Graphite-Samples of Materials and Products for Machinery', December 12, 1999 [4] Gu Dinghuai, etc.4 The specification tends to be larger In order to meet the development of technology and the needs of users, the company uses EDM A lot of work has also been done on the upsizing of graphite. As far back as the 1970s, in order to expand its own products and improve the quality and process level of graphite for EDM, the German Linsdorf Carbon Company spent 1.4.3 Wide application range, suitable for rough, fine and high speed playing.
