Micro Boring Head

Hole drilling turns out to be something pretty common in daily life. People might find themselves having to drill a hole to hang a frame, or to drill a hole to let the liquid flow out of the container. In the industries, the factories have to drill a hole all the time to either produce a part or to attach several parts together. But what if we want to not only drill a hole but also change the size of the hole? There is a small tool that allows us to change the size of the existing hole. It is the micro boring head.
 

Micro Boring Head

The micro boring head is used to change the diameter of the hole. As its name implies, the micro boring head is relatively small when compared with other types of boring heads. The micro boring head is also adjustable and it is suitable for various diameters and depths of the holes. Within the micro boring head, there is a device called cooling through-spindle. The cooling through-spindle can remove the chips easily when the holes are drilled deeply. The micro boring head is applicable to various types of machines. It can even be utilized in the boring process of the CNC machines.
 

Boring

To understand how a micro boring head works, we have to first understand the process of boring. Boring is a process of changing the size of a hole. Boring can make a pre-drilled hole larger. If the diameter of a hole needs to be very accurate, the technique of boring is used. It is also possible to use the boring technique to cut a tapered hole. There are several machines that utilize the boring technique, and each of them has its own pros and cons.
 

Precision Boring 

Precision boring is an operation that utilizes the technique of single-point cutting. The axis of the rotation of the cutting tool will move in a parallel way as the workpiece. This way the existing opening of the workpiece can be enlarged, and in turn producing an internal cylindrical surface that is very precisely made.
 

Jig Boring

Jig boring, on the other hand, creates a precise internal cylindrical surface by making an existing opening in a workpiece larger than it was. The axis of the hole is parallel to the single edge cutter, which is also rotating inside a stationary workpiece. The machine comes with several parts, such as the base, precision work table, column, and spindle housing. A rigid and solid boring bar is adapted by the jig boring machine to create deep holes and another device called the single point tool bits is used to create small holes.
 

Lathe Boring

When it comes to the making of the conical and cylindrical surfaces, the lathe boring is the process to choose. To make the hole which is in the workpiece larger, the single-point cutting tool has to move parallel to the axis of rotation. To create a taper on the workpiece, the cutting tool will, on the other hand, move at an angle to the axis of rotation. Not any special set of equipment is required to make this process work, except for the boring bar.
 

Vertical Boring

In the process of vertical boring, the large workpieces will rotate at a vertical axis, at the same time, the single-point cutting operation will be sent into the work. The depth and the diameter of the produced cut are controlled by the tool which advances vertically and horizontally. The machine for vertical boring is very similar to the machine for lathe boring. The vertical boring machine consists of a base, a rotating horizontal work table, a column, and a cross rail.
 

Horizontal Boring

In the process of horizontal boring, the tool of the machine will move in a parallel way to the axis of rotation. By advancing one or more rotating single-point cutters horizontally into a medium or large stationary workpiece, the hole is created. Horizontal boring machines can be applied in a lot of industrial operations such as milling, drilling, reaming, and tapping.
