| 6. | When this machine is used for the hardening processing of teeth , teeth will be embrittlement and snap due to its deeper depth of hardening . for this reason , we spend a lot of money to import the impulse hardened machine which can harden the depth 0 . 1mm 0 . 04 " of surface and make the hardness to be more than hrc67 hv900 本公司自行研发的锯研磨机,以高科技的cbn钻石砂轮直接研磨出锯形状form grind ,并由电脑控制精密度,以制造高精密零件的技术,将锯高度差控制在0 . 004 " 0 . 1mm之间,使锯切线不会歪斜。 |
| 7. | Abstract : in this paper , the laser transformation hardening ( lth ) system which used for die and mould and laser processing methods are introduced . the relationship between depth of hardening layer , wear resistance properties and laser hardening processing parameters are dicussed . the results show that die ' s service life can be improved by using lth technology 文摘:介绍了用于模具表面的激光强化加工系统和激光强化工艺方法,讨论了激光强化模具表面的硬化层深度和耐磨性能与激光强化工艺参数之间的关系,采用激光强化技术能大幅度提高模具的使用寿命。 |
