Drilling Machine Types
Types of Drilling Machine:
Following are the 8 different types of drilling
machines:
1. Portable drilling machine
2. Sensitive drilling machine
i. Bench mounting
sensitive drilling machine
ii. Floor-column
drilling machine
3. Upright drilling machine
i. Round column
upright drilling machine
ii. Box column
upright drilling machine
4. Radial drilling machine
i. Plain drilling
machine
ii. Universal
drilling machine
iii. Semi-universal
drilling machine
5. Gang drilling machine
6. Multiple spindle machine
7. Automatic drilling machine
8. Deep hole drilling machine
i. Vertical deep
hole drilling machine
ii. Horizontal deep
hole drilling machine
1. Portable Drilling Machine:
Portable Drilling machine
Portable Drilling machine
This sorts of drilling machines are commonly
utilized in all the workshop. Used to drill small sized holes. It is operated
by holding in a hand. The workpiece where the opening is to be drilled is held
during a vice.
2. Sensitive Drilling Machine:
Sensitive Drilling Machine
Sensitive Drilling Machine
This sorts of drilling machine wont to drill small
holes at high speeds in lighter jobs or workpieces. The machine could also be
mounted on the bench or floor & the drilling work is started with the drill
fed into the workpiece by purely hand control. Hand-feed permits the operator
to sense the progress of the drill into the workpiece, so that if there is any
drill worn out or jams it may be released immediately to prevent the drill bit
from breaking. Since the operator senses the cutting action at any instant it's
called because the sensitive drilling machine. These machines are capable of
drilling small holes of diameter as small as 0.35 mm to 15 mm. These machines
run at a better speed as high as 2000 rpm.
3. Upright Drilling Machine:
Upright Drilling machine
Upright Drilling machine
It is larger in size and stronger than sensitive
drilling machine. It is used for drilling medium and large-sized holes. Based
on the sort of column used it's classified as a round column and box column
upright drilling machines.
4. Radial Drilling Machine:

Radial Drilling machine
The schematic diagram of the radial drilling machine
is shown within the figure. It consists of the bottom , column radial arm,
drill head, spindle speed and feed mechanism.
5. Gang Drilling Machine:
Gang Drilling machine
Gang Drilling machine
This machine consists of the amount of drill heads
placed side by side in order that quite one hole of same or different sizes are
often drilled at a time on the same job or on different jobs. The space between
drill spindles is varied to suit the gap between the holes. This type of
machine tool is used to drill a large number of holes in the same job at a
faster rate. The main advantage of this sort of machine is that the series of
operation are often performed with different spindle mounted with different
tool bits on an equivalent workpiece by moving it from one position to another
position.
6. Multi Spindle Drilling Machine:
This machine is analogous to a gang drilling machine
in construction. It is wont to drill the amount of hole within the same
workpiece simultaneously and to breed an equivalent add variety of comparable
jobs. All the spindle are driven by one motor and fed continuously. During the
feeding table with the workpiece is raised or lowered and the drill head
position is not varied.
7. Automatic Drilling Machine:
Automatic Drilling Machine
Automatic Drilling Machine
This type of machines can perform a series of
machining operations at successive units and transfer the work from one unit to
the opposite automatically. Once the work is loaded at the primary machine, the
work will move from one machine to the opposite where different operations are
often performed and therefore the finished work comes out from the last unit
with none manual handling. This type of machine is meant purely for production
purposes and should be used for milling, honing and similar operations
additionally to drilling and tapping.
8. Deep Hole Drilling Machine:
Deep Hole Drilling Machine
Deep Hole Drilling Machine
This may be the either horizontal or vertical sort
of machine. In this drilling machine, the part to be drilled is rotated and
therefore the drilling bit that creates the opening is kept stationary. Deep
hole drilling is completed in components like rifle barrels, crankshafts, long
shafts etc.
