New tools and techniques to reduce the processing time up to 90%
发布时间：2015-05-14
In
recent years, hard car parts 'unknown' surface integrity also cause
some reluctance to hard turning as a key surface finishing. However, the recent development of the tool technology are likely to challenge these ideas. In particular, the new overall pcbn plunging inserts and new
technology has been proven and the traditional grinding process can be
comparable or better accuracy.
In
one recent development is the Xiangshan high cbn100 and cbn300 so hard
economical car finishing high selectivity of the overall pcbn blade. Especially
for machining hardened steel blade cbn100 and cbn300 overall offer and
traditional carbide blade inserts or the same number of cutting edges,
plus the length of the cutting edge. Due to their overall structure, provides new blade significantly higher abrasion resistance and lower cost per blade. In a study Seco overall blade with the other five different tool
manufacturers tipped blade comparison, each edge cost savings from 25%
to 208% range.
As an added advantage, cbn100 and cbn300 also makes it possible to plug the car. Plunging
a cutting edge or use the entire part of the cutting edge to create
hard turning of high productivity in the form of a right angle cut. This relatively new technology has been proven to reduce the
processing time by up to 90%, the surface integrity of parts produced
with those same grinding.
The
most critical feature of grinding or hard turning parts is the size
(diameter), roundness, straightness, bearing area, surface roughness and
residual stress. For the first four characteristics, for a large gear or bearing ring is inserted beneath the car can easily get accuracy.
