On March 21, 2014, B2-K1018 “Double Grinding Wheel Follower CNC Crankshaft Grinder†developed and manufactured by Beijing No. 2 Machine Tool Works Co., Ltd. passed the user acceptance test at Zhejiang Sun Co., Ltd.
Double grinding wheel frame follow-up type (cut point tracking) CNC crankshaft grinding machine is the important achievement product of the national 863 project, the "high-grade CNC machine tool and basic manufacturing equipment" technology major project and the Beijing Science and Technology Plan undertaken by Beijing No.2 Machine Tool Works Co., Ltd. One of the products is a high-precision precision grinding equipment for precision grinding of the crankshaft connecting rod neck and main journal of automobile engine. It adopts double grinding wheel frame synchronous grinding technology, CBN high-speed grinding technology, C-axis headstock synchronous driving technology, etc. International advanced technology, characterized by agility, flexibility, high efficiency, precision, etc., can realize batch precision machining of crankshaft connecting rod neck and main journal at one clamping, suitable for use in the production line of crankshaft production line; on-line measuring device with workpiece and error compensation Function; with perfect and reliable interlocking, safety protection, fault alarm, automatic fault diagnosis and other functions.
In the trial grinding stage, the crankshafts of various types and specifications of SAIC, BAIC, Geely and other companies were batch-grinded, the grinding process database was improved, and the reliability of the products was improved. In October 2012, the products were officially put into use in the crankshaft production line of Zhejiang Sun Co., Ltd., and the crankshaft products of the car engine were processed in batches. Through long-term verification on the production line, the machine precision and processing efficiency fully satisfied the user's production and technical requirements. Some indicators are superior to imported equipment on the production line.
B2-K1018 double wheel frame follow-up type (cut point tracking) CNC crankshaft grinding machine is put into use in the domestic crankshaft production line, which realizes that Beijing No.2 Machine Tool Works Co., Ltd. can be used in one of the key parts of the automobile - crankshaft finishing Provide all the equipment for grinding and polishing processes to meet the goal of the whole line. Beijing No. 2 Machine Tool Works Co., Ltd. has also become the only grinding machine manufacturer in China that can be equipped with complete lines.
The integrated application and innovation of the special technology achievements of Beijing No.2 Machine Tool Works Co., Ltd. in the domestic crankshaft production line reflects the independent innovation and breakthrough bottleneck of domestic machine tool manufacturing enterprises, meets the automotive industry's desire for domestic high-end CNC machine tools, and enhances the key parts of China's automobiles. The manufacturing capacity, comprehensive replacement of imports, and the simultaneous development of the automotive industry and machine tool manufacturing industry are of great significance.
Swing Door And Window Aluminium Profile
The Swing/casement window is divided into a push-pull type and an overhang type. The utility model has the advantages of large opening area, good ventilation, good sealing performance, excellent sound insulation, heat preservation and impermeability. The inner opening type of window cleaning is convenient; the outer opening type does not occupy space when opened. The disadvantage is that the window width is small and the field of view is not wide.
