Improve efficiency of grinding and reduce
cost by curb the generation of burrs.
The major issues of needle grinding are occurrence of burrs and lifetime of grinding wheels. Many grinding wheel makers try to improve their wheel’s lifetime by increase hardness. However, it usually generate many burrs when proceed the grinding to the first bevel.
Our manufacturer recognize that solving these contradictory issues simultaneously is the most
important task imposed on the grinding wheel manufacturer.
We have
always been aware of the problem and have been working on the development of
grinding wheels for injection needles.
◆We improved lifetime of our grinding wheel by using the new blinder
We newly adopted an ester binder for the
production of grinding wheels.
Comparisons with our previous models have
resulted in a 20% increase in its life.
Furthermore,
we have received high marks in the running test at major users and it has been
adopted.
◆Reducing the generation of burrs
Usually it is thought that grinding by ester
binder wheel is difficult. However, Our company manufacture the grinding wheels
with our own know-how.
Reducing the generation of burrs makes it
possible to save the time of burr removing work and reduce the defective rate.
