★
If ground material is steel or alloy, the abrasive usually be oxide, if it is
iron, non-ferrous metal or nonmetal, abrasive would be carbide. Fine grit
size abrasive is propitious to soft, high ductility material. Hard grinding
wheel grinds soft material, soft grinding wheel grinds hard material. The
grinding wheel of Dense structure grinds hard and brittle material, the
grinding wheel of open structure grinds soft and ductile material.
★
About precision and roughness, advise adopt high speed grinding to
gain a bit high precision and a bit low roughness, if use coarse wheel.
Adopt fine grain wheel to gain high precision and low roughness.
★
About interface, dense structure wheel is propitious to small interface,
whose grain is request fine and hard. Open structure wheel is propitious
to big interface.
★
Feed is faster, grinding press is heavier, the grinding wheel is request
harder, the opposite feed would automatically increase with table moving
speed increase at equal absolute feed speed, so as to the grinding
wheel wears fast, the wear would improve using hard grade wheel.
Note: Bigger for feed, more probability for the grinding wheel
breaks.
5.5. INSPECTION OF THE GRINDING WHELL
Must stand to the following safe regulation, the regulation is to assure
operator safe.
1) Should inspect the grinding wheel before fixed. In general way, it is well
to test the voice of the wheel. Use an mandrel passes the center bore of
