Main Features and Benefits of CNC Milling Machine

CNC (Computer Numerical Control) milling machine is one of the common machine tools in machinery industry. It is the popular form of CNC that can perform those repetitive tasks of drilling and turning that used to be human jobs long time ago.

 

CNC Mills are classified based on the number of axes that they have. Axes are labeled as x and y for horizontal movement, and z for vertical movement.

 

Basically, this milling machine has four axes which are Milling Head Z, Table Z, Table Y, and Table X. The quantity of axes it has is often presented in many different ways.

 

For example, there is a five-axis machine. The extra 5th axis is in the form of a horizontal pivot for the milling head that ensure the excellent flexibility of machining with the end mill at an angle follow the table.

 

It is usually programmed by using a series of standard commands that we named it as G-codes to represent specific CNC tasks in alpha-numeric form.

 

There are many different sizes for this machine based on the purpose and location of usage, as well as the materials that need to be cut.

 

Besides that, the size of motor affects the speed of cutting the materials. Normally, materials like plastic and wood are the easiest things to cut, unlike steel that need stronger milling machine and longer time.

 

To evaluate the performance of milling, we can look at its rigidity. For example, the more rigid a mill is, the more precisely it drills and cuts. CNC mills normally have better & tougher engines for higher rigidity compared to manual counterparts.

 

With CNC milling machine, we can improve the speed of cut compared to manual operation. It also reduced the rejection when rigidity results increased. Thus, in long run business, it will indeed save a lot of time and overhead due to less wastage happened.

 

Another benefit is the accuracy of cut through CNC milling machine with a computer numerically controlled machine. In production line, it is very important to have all the parts produced exactly the same. However, nothing is perfect. CNC milling machine may also have a possibility of fault lies in the operator due to a mill can cut with absolute precision as close as.0001 of an inch.

 

In addition, many mills have beds that are able to move at different angles for easy cutting jobs, different angled cut as well as more difficult drilling operation. This is one of the benefits over manual mills.

 

Lastly, with the automated cooling systems, it is able to maintain the quality of raw material by spraying or blasting the hot metal or even tooling with specially formulated coolant.

 

With the benefits of CNC milling machine stated above, it is really worth the money to invest a CNC milling machine for your business use. And there are the popular brands that available in the market, such as Mori Seiki, Dahlih, CNC Takang, DMTG, Mastika, HACO, Takisawa, Okamoto, Creator, Agma, L & L, Hurco, Okuma, Extron, Enshu, Equiptop, Komatsu, Jiuh Yeh.

Milling Machine Types and Uses

Milling machines are used mainly for shaping and cutting solid materials such as metal, wood, plastics or even brass. These machines differ from a lathe in that the tool head itself rotates at high speed whereas with a lathe the part itself that is being worked on rotates. This sort of machinery varies greatly in terms of cost and in the specifications of the machine. Hobby machines will obviously be a lot more cost effective than their industrial counterparts.

 

So we will be a taking a look at some of the milling machine features and some of the important things to consider when looking to buy a machine for home or industrial use.

 

Types of Milling Machine

 

Found more often than any is the column type of machine. It has a few basic parts and is pretty simple. Materials can be drilled by means of the vertically suspended cutting device.

 

The turret mill is a more versatile option than the column machine. It is capable of producing many types of products as the spindle can be aligned in many different positions.

 

The C-frame is more usual to be found in an industrial workplace. It is tremendously powerful to cope with larger milling jobs.

 

Horizontal and Vertical Mills

 

These two types of machine are fairly similar, the main difference is the vertical machine’s spindle has a vertical orientation as the name suggests. It’s good for plunge drilling and cutting.

 

A horizontal mill has the cutter or cutters located on an arbor. This type of machine is good for heavy cutting like slots and groves for instance.

 

Digitally Controlled

 

The CNC (computer numerical control) machine or sometimes referred to as machining center is a highly accurate form of milling. The machine is set up usually via computer aided design technology. This sort of control allows the part to be engineered to a high level of complexity such as engraved elements and relief. The precision achieved is unsurpassed and with little operator input needed following the set up phase and the production of the test piece it’s also cost effective.

 

Important Considerations for Purchase

 

It will depend an enormous amount on what the machine is required to do of course. So it’s important to look at the complexity of the work to be done and consider the number of axis variants required. The power of the machine will also be important as will the speed that it operates at. As some milling machines will come with various attachments others will require these at additional cost. The overall cost may be important and some really good used milling machines can be found online if needed.

 

So I have taken a look at some of the milling machine types and their uses along with what sort of things to look out for when considering the right one to get.

Choosing a Vertical Milling Machine

There is really not a lot to know about how a vertical milling machine operates. It is really quite a simple process and very easy to understand. It simply uses a rotating cutting tool that makes machined surfaces. It does this by removing material from the workpiece itself. It also has the capability of a drill because its spindling device is perpendicular to the table. The drill can then be driven into the workpiece.

This type of machine is run by various control functions. Machine mills include start and stop buttons, forward and reverse levers which control the spindle’s rotating direction, a braking device for the spindle, a spindle speed regulator, a handwheel which moves the table both in and out and a handcrank that raises and lowers the table. Other control features include a handle to move the spindle and a lock that activates when the milling process begins. There is also a spindle stop, feed level and selector available on many models. Often vertical mills are completely automated, making the entire process free of manual labor.

One of the best companies manufacturing milling machines today is Bridgeport. This excellent company offers a complete line of vertical mills. It stands by all of its products and prides itself on the affordability of its products and its high performance standards. With a Bridgeport mill, the customer always comes first and is assured that all parts will be completed with perfection every time. A Bridgeport is built for accuracy and will last for many, many years. The customer can be confident that a Bridgeport vertical mill will give outstanding and reliable performance via its quick traverse rates, durable spindles and innovative control systems.

A vertical milling machine today contains the most up-to-date features and often is digitized for even better performance. Its digital readouts increase the accuracy of cuts and enhance overall productivity. With these readouts, the table movement can be accurately measured to 2/10,000 of an inch. Additional features of these readouts are that they can run with either relative or absolute measurements and can display information in millimeters and/or inches.
