Large machine shop
drills use induction motors.
Oilwell drilling machines use
diesel motors or diesel-electric rigs.
Drilling rigs can be massive structures
housing equipment used to drill
water wells, oil wells, or natural
gas extraction wells, or they
can be small enough to be
moved manually by one
person and such are called augers.
Radial drilling machine.
Upright drilling machine.
Automatic drilling machine.
Multiple Spindle drilling machine.
The electric motor drives
the spindle either directly
with a gearbox or with a
series of belts and pulleys.
The electric motor can either
be mounted to the base of the
machine or at the top of the column.
Like the feed rate, the rotational speed
can be adjusted for different
drill bits and materials.
Designed for on and off
shore drill rig service,
bulk fuel terminals,
and transfer stations.
Designed to withstand
hazardous-duty applications
with demanding service factor
needs. Labyrinth style
recess shaft slinger increases
bearing life and multiplies
durability.
Workover rigs are very
similar to drill rigs in
that they are truck-mounted
mobile rigs that travel between
job sites on public roads.
However, these machines
are generally located at
the job site for weeks before
relocating to a different location.
