GM1230 grade is made of newly developed ultra-fine Al2O3 and nano columnar MT-TiCN coatings, matching strong carbide substrate made with coarse grains and smoothing surface treatment. This new grade thus exhibits wonderful heat dissipation, superior adhesion resistance, longer tool life and machining stability. It is suitable for stainless steels in semi-finishing or roughing cutting conditions with medium speeds.
耐磨性测试
Wear resistance tests
本案例为圆棒外圆连续车削加工，被加工材料为316L不锈钢，采用搭载GM1230牌号刀具进行对比测试，较原有GM1125牌号，其抗沟槽磨损性能和最终使用寿命均具有显著提升。
This case is a continuous turning process on 316L stainless steel cylinders. Compared with the original grade GM1125, this new grade GM1230 showed better notch wear resistance and longer tool life.

Toughness tests
The new grade GM1230 also shows improved toughness and more stable service performance. In the intermittent turning of 304 stainless steels, the single edge processing time of GM1125 is 8.7 minutes, the improved grade GM1230 can reach 10 minutes.
