Definition of Machining centers

It is a machine that is for both milling and hole making on variety of shapes. The history of machining centres started in 1958 when Kearney & Trecker Corp of the U.S. first made the practical prototype of fully functional machining centres whose name was given "Milwaukee-Matic Model II". Mitsubishi Heavy Industries, Ltd. or (MHI) did bring a heavy impact for these machines from time to time as around 1958 they began to study the introduction of NCs into machining centers and due to the increasing needs, they developed many machining centers by adding more useful features to it.

Processing of Machining Centres

One of the unique features of machining centres is the tool changer which moves the tools in rapid sequence from storage to spindle. These machines can generally store from 20 to 40 individual tools with the maximum capacity of 200 or more parts. But the universal machining centre which was made later could carry both. As from above we know that these machines are of two types, the vertical type is used when the work is done on a single face.  With the use of rotary table’s, one side of work piece or multiple work pieces can be built without any human intervention. These rotary tables have four axes of motion. The three axes are lineal motion and the fourth one is the table’s rotary axis. But for the horizontal machining centre with horizontal spindle is better suited for larger and more complex work pieces. Like the vertical ones, horizontal centres also have multiple axes table movements which rotate to all four sides. But in the case of the universal machining centre, both the types (horizontal and vertical) are present for gaining a larger variety of angles by the combination of tilts and swivels of the spindles.

Where, and for what Machining Centres are used?

 These machining centres are nowadays a vital ingredient for success and better quality products for many leading industries such as the die & mould industries, power generation equipment industries as well as aerospace and automobile industries as these machines helps all these companies in their own manufacturing ways with three things in common which is processing at high speed with high accuracy and high quality. 

Who produces the machines for Machining Centres

As these machines have become an initial part of many modern industries, MNCs like The (MHI) or the Mitsubishi Heavy Industry have started in developing these machineries for quite some time as they promise the three most important features in all their products which are processing at high speed with huge accuracy and quality which made this company one of the best of its class. There are many models to choose from but the latest versions of these machining centres are the Σ Series vertical machining centres "M-V50" and "MV50-FM" and the horizontal Σ Series machining centres "M-H60" and "M-H80" with further adding the "M-V70" and "M-V70-FM" to the Σ series.

Advantage of buying a Machining Centres

The machining centers are quite a good fit for projects which are extra large in dimension. These devices can perform both vertical and horizontal functions equally. They do offer increased ratio of productivity.
