A drilling machine which is also known as a drill press is a cutting process that uses drill bits of various sizes to cut a hole of circular-section in solid materials like metal, plastic, wood, rocks, etc.

The drill bit as the cutting tool rotates, is often multi-point. This drill which rotates from hundreds to thousands of revolutions per minute is pressed against the workpiece with force. The force applied causes the cutting edge to cut off chips from the workpiece.

Today we’ll be looking deep into drilling machine types, operations, maintenance, advantages, and disadvantages etc.



Drilling machines are available in different shapes and sizes, varying from small hand-held power drills to bench-mounted and finally floor-mounted versions. They are used to carry out operations such as countersinking, counterboring, reaming, spot facing, as well as tapping large and small holes. Due to the fact that drilling machines can perform the operations, principles, and drill bits achieving them totally varies.

applications of drilling machines with the use of drill bits with sharp cutting edges are used to achieve various hole sizes on operations mentioned above. The operator must know how to set up the work, set speed and feed, as well as coolant to obtain a quality hole.

Safety and Maintenance

One of the major maintenance of a drilling machine is by lubricating in between the drill bit and workpiece while working. This helps to dissolve heat and friction generated by the moving parts. Some manufacturers offer manuals for proper lubricating methods and cleaning methods.

The drilling machine is expected to clean after use and clear the chips to avoid damage to the moving parts. Ensure spindles and sleeves are free from grit to avoid damaging the precision fit. To prevent rust on the machine parts, especially the bed, the oil should be lightly coated on their surfaces.

Drilling larger holes requires some special care to avoid injuries to the operator. The part should hold one vice or join with other metal parts that will stop the workpiece from moving. It should be operating at slow speeds to avoid rapid abrasive wear on the moving parts. Lubrication should also be added more often.

When the machine is in extremely cold conditions, the machine should work at a slow speed. Allow the parts and lubricants to warm up before increasing the speed.

Safety precaution to be taken in drilling operation as it involves power equipment. It must be considered to prevent damage to the equipment, operator, and people nearby. To avoid this, serious care must be taken in maintaining and setting up the work and proper working tools should be selected. The holding device should also be in good condition to avoid damage.

Advantages and disadvantages of drilling machine

The benefits and limitations of the drilling machine may vary according to the types and their application. But the general benefit occurs in their end product.

Drilling machines help to mark the end of components of dresses, especially for setting packets, darts, etc. and they can make the hole permanently for a long. While the limitation is the limited use of the machine.

Other advantages and disadvantages will be explained under different types.
