Precision Surface Grinder Machines
Surface grinders
are used for various grinding processes including truing flat metal stock,
squaring material within tenths, sharpening cutting tools and for sharpening
punch and die sets. A surface grinder normally consists of a magnetic
chuck, which resembles a table, the grinding wheel that is attached to
a rotating spindle, and a few handwheels (if manually operated). The workpiece
is placed on the magnetic chuck and the chuck is then activated either
by a switch or lever. When the chuck is activated the part is then held
firmly to the magnetic chuck. The grinding wheel is then moved down to
the top of the workpiece using a handwheel, until the grinding wheel touches
the part (carefully), then you can begin moving the table side to side
and front to back until the entire surface of the part is ground. If more
of the surface needs to be ground, move the table so the grinding wheel
is off the workpiece and lower the grinding wheel about 0.0002" to 0.0004"
using the tick marks on the handwheel and begin moving the table again,
this process can be repeated until the desired dimension is accomplished.
Remember to follow all safety rules for surface grinders as these machines
can be dangerous if used improperly. Eye protection is a must.
