Drilling is one of the most common machining operations. A drilling machine by Pathak machine industries is featured by a rotating cutting tool that advances along the axis into a stationary workpiece creating a hole. The common operations that can be performed on a drill press are – drilling, reaming, boring, countersinking and tapping. The capacity of the drilling machine is determined by the size of the largest workpiece on which the spindle can be centered. Drilling machines can be categorized into five major classes- upright, radials, horizontals, turret drills, and multiple-spindle machines.
Types Of Drilling Machine
Upright drills include large groups and are featured by a single vertical spindle moving in a fixed position.
Radial drills are made to handle large operations. The machine is designed to position spindle to drill at any area within the access of the machine through movement created by the head, arm and arm rotation about the column.
Horizontal drills feature the special spindle position. They have self-contained units comprising of motor drive, gear, and a spindle that can be mounted at any predetermined drill angle and are widely used to meet high production requirements.
Turret drilling machines feature numerous tools mounted in a turret designed to handle a series of operations. The machine also features a computer numerically controlled machine.
Multiple-spindle drilling machines are designed with fixed spindles for single-purpose production and where the spindles are adjustable by universal joints or by traversing along with a worm or spiral drive in a straight line. These drilling machines in Howrah Kolkata, India are widely used for high production rate samples.
A commonly used type Twin spindle drilling machine for mass production has a major role in the mechanical industry to increase the productivity of machining equipment. It is a production type of equipment to drill double holes in a required simultaneously. The holes are drilled on various pieces with the same accuracy to make them interchangeable. Both spindles are driven by a single motor that is fed into the material together. Feeding motions are received by raising the work table or by lowering the drill’s head. In large scale production work drill jigs are used to direct the drills in the workpiece to achieve the desired outcomes.
It is difficult to estimate the drilling depth, even a nominal human error, the operation may fail, additionally, different size holes cannot be drilled without altering the drill bit. To solve such issues, an automated drilling machine is designed that aims to drill the holes automatically.
