人们越来越需要对珩磨工艺进行新的改进。激光珩磨和同轴珩磨是最有趣的变化。内燃机活塞运转区域的激光珩磨在功能和耐久性方面具有不同的优势。减少排放和生产成本是主要特点。通过激光珩磨，可以实现表面轮廓的特殊设计。同轴珩磨允许孔的所有零件对齐，尽管珩磨前孔的单个零件发生了显著的位移。在部分硬化或大孔中断的孔中，这是可能的。

New modifications of honing processes are required more and more. Laser honing and coaxial honing are the most interesting variations. Laser honing of piston running areas of combustion engines gives different advantages concerning function and durability. Reduction of emissions and production costs are the main features. With laser honing a special design of surface profile can be realized. The coaxial honing allows an aligned position of all parts of a bore in spite of significant dis-position of single parts of bore before honing. This can be possible in bore with partial hardening or large bore interruptions.
