CAD Project: Drilling Machine

The document proposes a project to design a drilling machine. It describes the key parts of a typical drilling machine, including the spindle, sleeve or quill, column, head, worktable, and base. The spindle holds the drill and revolves while the sleeve feeds the drill into the workpiece. The column supports the head and sleeve. The head contains the motor and feed mechanism. The worktable can be adjusted and tilted for different drilling operations. The base supports the entire machine.

1.0 INTRODUCTION

Figure 1 shown a drilling machine as it is one of the most important machining tools
in a workshop. By using a drilling machine, holes can be drilled quickly at the most efficient
way and low cost. Rotating edges of a cutting tool known as the drill which exerts large force
on the work clamped on the table and created a hole as the machine tool exerts a vertical
pressure to originate a hole it is loosely called a drill press. Drilling machines are made in many
form factors, each of them is designed to handle a class of work or specific jobs. A drilling
machine comes in many shapes and sizes, from small hand-held power drills to bench mounted
and finally floor-mounted models. Many operations other than drilling can be done such as
countersinking, counterboring, reaming, and tapping large or small holes.

2.0 PRODUCT DESCRIPTION

Figure 2: Construction of drilling machine.

All drilling machines have the following construction characteristics as shown in


Figure 2 a spindle, sleeve or quill, column, head, worktable, and base. The spindle holds the
drill or cutting tools and revolves in a fixed position in a sleeve. In most drilling machines, the
spindle is vertical and the work is supported on a horizontal table. The sleeve or quill assembly
does not revolve but may slide in its bearing in a direction parallel to its axis. When the sleeve
carrying the spindle with a cutting tool is lowered, the cutting tool is fed into the work: and
when it is moved upward, the cutting tool is withdrawn from the work. Feed pressure applied
to the sleeve by hand or power causes the revolving drill to cut its way into the work a few
thousandths of an inch per revolution. The column of most drill presses is circular and built
rugged and solid. The column supports the head and the sleeve or quill assembly. The head of
the drill press is composed of the sleeve, spindle, electric motor, and feed mechanism. The head
is bolted to the column. The worktable is supported on an arm mounted to the column. The
worktable can be adjusted vertically to accommodate different heights of work. or it may be
swung completely out of the way. It may be tilted up to 90° in either direction, to allow for
long pieces to be end or angled drilled. The base of the drilling machine supports the entire
machine and when bolted to the floor, provides for vibration-free operation and best machining
accuracy. The top of the base is similar to a worktable and maybe equipped with T-slots for
mounting work too large for the table.
