Boring Bar

Boring bars are the tooling system of the boring machines that are installed unto the tooling units as the boring bars for the sake of boring. Boring bars are made of hardened metal materials so that the boring bars can bore the drilled holes in a convenient manner instead of in harsh efforts.

Boring Bars and Boring Machines

Boring machines are the machine tools with the machining process utilizes spinning boring bars to bore materials by enlarging a hole that has already been drilled by means of a single-point cutting tools, such as in boring a gun barrel or an engine cylinder under the control of people, and the control system involving the boring bars and the working motors may be of manual, or a CNC computer numerical control system, yet nowadays this kind of machines is usually controlled by the CNC systems and the precision value is controlled within a relatively small tolerance since the boring bars and the relevant units are well managed. The boring methods of the boring bars and the work pieces could be done on different directions that are based on the different tracks installed on the axes, which are installed on the moving tracks of the machine body.


Horizontal Boring Bars Installed on the Boring Machines

Horizontal boring machines clamped with boring bars are the most commonly seen boring machinery that is designed with the machining process utilizes spinning boring bars to bore work piece materials by enlarging a hole that has already been processed by means of a single-point cutting tool, such as in boring a gun barrel or an engine cylinder under the control of CNC system.

Today, this kind of machines is usually controlled by automatic programmed CNC system and the precision is controlled within a relatively accurate tolerances. The boring methods regarding the boring bars could be done on different directions that are based on the different axis, which are installed on the moving box in box tracks of the machine tool body frames. Many of the milling machines and machining centers are capable of boring operation for simple processing after the complicated milling mechanism. Furthermore, some advanced drilling machines are also designed with boring functionality now in order to keep up with the fast cycle time requirement and under the horizontal structure with the horizontal boring bar arrangement.

Moreover, many boring machines with special boring bars are now equipped with other metal working machining capacities rather than just doing one type of works, so that onsite operators can do more than one job on the same machines rather than moving the work piece items from one working table to another, squandering a lot of precious working hours and energy and expenses. There are many boring machines that are designed with milling functionalities; here below let’s take a look of the other boring bars and machines. 


Vertical Boring Bars and Machines with Milling Capacity Added

After the horizontal boring machines with horizontal boring bars, vertical boring and milling machine is the focus in this section. This is normally a milling oriented machine tool that is designed with vertical align structures. This type of machine tool is a highly developed and widely applied machine tool that can deal with many kinds of mill tasks all at one stop if the milling machine is equipped with supportive accessories such as ATC, tool magazine, APC, and rotary tables.

Speaking of the origin of vertical version boring machines, the vertical boring and milling machine is developed from conventional milling machines with boring capacity that aims to deal with further finishing processes only as an added value of the milling machines. But since then, the development of this specific type of machine tools goes well in the industry, and after that, machine centers are widely applied in all kinds of industries, contributing a wide range of industrial efforts due to the great competence it carries and the corresponding agile versatility it has. As a result, vertical type boring and milling is recognized as important in the manufacturing lines in the factories. 


Boring Bars on Movable Axis

For the versatile working models, the movable axis of the boring and milling methods are big issues for the boring and milling machines, since they help things to be done on different directions that are based on the different tracks installed on the axes. The number of axes depends on the customers’ demands and there is no absolute optimal number but only the most suitable choices based on users’ requirements. Besides turning, milling and boring cover a wide variety of various operations and ranges a wide scale from single tiny parts to heavy and large gang milling operation tasks. Similar to turning, milling and boring are the most widely adopted machining methods that render accurate tolerances.
