Speciality
and Choice of Grinding Apparatus
|
| · |
Resin grinding apparatus are the
ones which are used to grind,cut and
polish metals affer being solidified
into the different shapes by the means
of using resin to stick grinding materials.Their
specialities vary from grinding apparatus
to grinding apparatus.Lf you want to
get the ideal effect,you should choose
the suitable grinding apparatus.
The specialty of grinding apparatus
persists of grinding materrials,size,hardness,organizing
number,paste,form,dimension and so on.

Tool's grade |
| The grade means the diffculty
for the abrasive grain on the tool's surface
to be pullcd out by grinding force. the
abrasive whos grain is easy to be pulled
out shows lower lower grade,conversely.it
shows higher grade. the abrasive tools
made in china fall into 7 major grades
and 16 detailed grades. |

Crain size |
|
The abrasive plays amainn part in
grinding. There are two major kinds
of conventional abrasives,aluminium
oxide and silicon carbide.
The term"grain size"means
the size of abrasive particles and is
to be chosen depending on the required
accuracy,surface finish of the work
to be groud and production effciency.According
to china National standard GB/T2476-94
the grain size is subdivided into four
groups. Grain,powder,micropowder and
fine micropowder. |

Tool's selection |
| In accordance with the
grinding and cutting theory,the principls
on choosing and using grinding apparatus
are:we need varioud grinding materials,
pastes,hardness and roganizing numbers
to deal with vatious models of steel or
non-metal materrials under various situations
in order to get the best cutting effect.The
general advice on choosing the resin cutting
grinding wheel and cymbal-like grinding
wheel producted by our company are followed: |
