CNC is an abbreviation for Computer Numerical Control.
This indicates that a computer converts the design created by CAD (Computer Aided Design software), into numbers. The numbers should be viewed as the coordinates of a graph and they manage the operation of the cutter. This is how the computer get to control the shaping and cutting of the material. The coordinates X, Y and Z axis manage the movement of the cutter on a 3D CNC machine. This assures that the materials will be machined in three directions (3D manufacture).
CNC Precision Engineering Services fulfill their task much quicker and stronger than humans would. It’s flexibility allows us to have it reprogrammed in a second in order to produce another product. Molding and shaping of woods and metals have never been easier since the arrival of machines as CNC.
You have the option of referring back to the old programmes or install some new ones if different pieces are required to finish the work.
Many industries implement the usage of CNC. For instance, it comes in very handy when it comes to dying, cutting and shaping of equipment, jewelery making, drilling and metal holding.
CNC machines are easy to use, they are included in various processes, such as Injection Molding, CNC Vertical Milling, CNC Lathe and EDM machining.
What are the advantages of using CNC machines?
- It is logical that profit increases every time waste decreases, so CNC helps you save money by allowing you to make full use of raw materials.
- Also, CNC machines have the ability to reduce the number of steps required in order to manufacture certain parts.
- Most CNC machines have an internal quality assurance detector, which puts this way of machining at the top of the efficiency pyramid.
- CNC machines are very safe for the operator, you can be much more relaxed and be sure that you won’t be in any danger zone during the whole process.
A CNC mill consists of: linear bearings and ball screws, stepper motors, controllers, spindles and cutter heads, cooling and dust removal.
There are several types of CNC machines: Vertical CNC mill, Box mill, Horizontal CNC mill, C-Frame mill and Knee mill.
What are the components of a CNC milling machine?
- Control panel – The control panel is the most important part of a CNC machine. It consists of a computer keyboard that is utilized by the technician to enter G-codes (commands) on the machine.
- Coolant supply tube – During the process of milling a metal, the machine and the metal both become rather hot. Then the coolant supply tubes are activated to start pumping the coolant material to cool and lubricate the metal. The lubrication accounts for a more smooth movement.
- Table – The surface on which the work piece is attached and where the metal, wood or plastic that are to be milled are kept.
- Axis – A CNC machine can have one or more axis. The maximum number is six.
- Column – It is the component that moves along with the axis and secures the milling part.
- Cutting tool – This tool is attached to the column, and as the name itself indicates, it carries out the most important task that is the goal of these Precision Engineering Services – cutting the material and finishing the job.
