珩齿如同剃齿一样,可提高齿轮精度,但比剃齿优越。因珩齿不仅可加工软齿面,且可加工硬齿面。高性能的齿轮都要进行热处理,但热处理总会产生变形,而这种变形并不总是有规律的,想采用热前剃齿或挤齿来补偿产生的变形,往往不能稳定地达到所要求的精度。传统的珩齿工艺是采用齿轮状珩轮,由于珩轮精度低、珩削性能差等原因,所以难于提高齿轮精度。因此,国内外都致力于研究一种能部分代替磨齿加工的珩齿法。
Honing teeth, like shaving, can improve gear accuracy, but superior to shaving. Due to honing teeth can not only soft-tooth surface processing, and can be hardened surface. High-performance gear must be heat treatment, but the heat treatment will always produce deformation, and this deformation is not always regular, want to use the hot pre-shaving or squeezing teeth to compensate for the deformation, often can not be achieved consistently The accuracy. The traditional honing process is the use of gear-like honing wheel, honing wheel due to low accuracy, honing poor performance and other reasons, it is difficult to improve gear accuracy. Therefore, both at home and abroad are devoted to studying a honing method that can partially replace the grinding process.
