What are the main parts of the drilling machine?
The basic parts of a drilling machine are a base, column, drill head and spindle. The base made of cast iron may rest on a bench, pedestal or floor depending upon the design. Larger and heavy duty machines are grounded on the floor. The column is mounted vertically upon the base.

What is the diameter ratio?
Circles are all similar, and “the circumference divided by the diameter” produces the same value regardless of their radius. This value is the ratio of the circumference of a circle to its diameter and is called π (Pi).
What is diameter length ratio?
One of the parameters which affect the uniaxial compressive strength (UCS) of rock materials is the length to diameter ratio (L/D) of test cores. ASTM recommends a ratio of between 2 and 2.5, and ISRM suggests 2.5–3:1.

What is gun drilling and how does it work?
What is Gun Drilling? Gundrilling is a deep hole drilling process that uses a long, thin cutting tool to produce holes in metal at high depth-to-diameter ratios. Gun drilling is effective in diameters from 1 – 50 mm [0.04 – 2.00 in].
What are the tools used in a drilling machine?
The most commonly used tools in a drilling machine are Drill Reamer Counterbore Countersink Tap Drill A drill is a tool used to originate a hole in a solid material. A helical groove known as ‘flute’ is cut along the length of the drill. Different types of drills are Flat Drill Straight fluted drill Twist drill Centre drill
How deep can you drill with a gun drill?
In the machining world, drilling depths of 10 x D and dee- per are regarded as deep hole drilling operations, whereby smaller drilling depths can naturally also be produced with gun drills. Advantage is taken of the positive side effects, as for example good surface quality, low deviation from concentricity and optimised alignment accuracy.
What is a drilling machine?
Drilling can be called as the operation of producing a cylindrical hole of required diameter and depth by removing metal by the rotating edges of a drill. The cutting tool known as drill is fitted into the spindle of the drilling machine. A mark of indentation is made at the required location with a center punch.
