随着我国机械工业和航空工业的迅速发展,燃汽轮机、发动机叶片都采用了抗高温性能较好的镍基耐热合金,如In738、U500、M17、K6和K3等材料,由于这类材料的切削性能差,采用铣削加工存在着生产效率低,刀具寿命短,成本高等缺点。采用强力磨削这一新工艺,就需要有相应的机床、砂轮、修整工具、冷却液和磨削工艺等。我们主要承担研制强力磨削砂轮的任务。 With the rapid development of China’s machinery industry and aviation industry, the heat-resistant alloys such as In738, U500, M17, K6 and K3 are used in gas turbines and engine blades due to their high temperature resistance. Cutting performance is poor, there is the use of milling low productivity, short tool life, high cost shortcomings. The use of powerful grinding of this new technology, you need a corresponding machine tool, grinding wheel, dressing tools, coolant and grinding technology. We mainly undertake the task of developing grinding wheels.
