Drilling Machines Area-Chiko Precision

A drilling machine is designed to cut precise cylindrical holes in just about any material. There are many different types of drilling machines available on the market. From handheld drills to multi-head turret drilling machines, each type has its own set of advantages, disadvantages, and ideal-use cases. 

This article will describe the different parts of a drilling machine, the different types of machines available, and the specific uses of these machines.

What Is a Drilling Machine?

A drilling machine is a power tool that is used to create cylindrical holes in a workpiece. The tool bit is rotated at high speed and pressed into the workpiece to create a cylindrical hole that passes either partway (blind hole) or all the way through (through hole) the part. A drilling machine's speed is adjustable, and the feed rate into the workpiece can be either manually or automatically. Drilling machines can be mounted directly to a concrete floor, to a work table, or can even be portable. Figure 1 below is an example of an industrial drilling machine:

What Are the Uses of a Drilling Machine?

A drilling machine is a tool used for drilling holes in various materials, such as metal, ceramic wood, or plastic. It can be either portable or stationary. A drilling machine is very versatile and can be used to make a variety of hole types and geometries as listed below:

Drilling: The most common use of a drilling machine is making either blind or through holes in a workpiece.

Reaming: Used to finish an already-drilled hole, improving both its dimensional accuracy and its surface finish.

Countersinking: After a hole is drilled it may be necessary to create a countersink in the workpiece. A countersunk hole has a conical cutout to accommodate the head of a fastener that must be flush with or lower than the surface of a finished part.  

Tapping: Once a hole has been drilled, it may need to be threaded to accept a threaded fastener like a screw or bolt. A tap can be attached to the machine and used to cut internal threads.

Boring: A drilling machine can be used to increase the diameter of an existing hole through the process of boring. 

Counterboring: A counterboring tool is used to create a shallow, enlarged cylindrical cutout so that a fastener's head will fit flush with or below the work surface.

What parts need to be proceessed by drilling machine?

All mold parts and molds or Machining parts which has holes.
