Your questions and answers from our specialists
CNC machines of the highest quality
CNC stands for "Computerised Numerical Control". It is a computer-aided manufacturing process for multi-dimensional machines, so-called CNC machines.
The advantages of computer-controlled technology are the high efficiency of production, but also the high and always reproducible precision with which the workpieces are processed.
CNC machines are used in a wide variety of areas. In the skilled trades as well as in industrial production. Depending on the design and tool, they are suitable for milling, turning, cutting (with water jets), drilling, engraving and other tasks. Plastics can be processed just as successfully with these machines as metal.
CNC machines work multi-dimensionally across two to six machining axes and carry out all the steps required on a workpiece in a single operation. Even highly complex geometries can be realised without any problems. This saves a great deal of time in production. Thanks to computer-controlled technology, CNC machines achieve a very high level of precision that can be repeated at any time. Particularly powerful machines even carry out tool changes automatically and even monitor tool wear or breakage. This further reduces the need for support staff. Another advantage is the high degree of customisation. This means that the machines can be customised to meet individual production requirements. There are simple CNC machines that are suitable for one machining process such as milling or turning, but also so-called CNC machining centres in which a workpiece undergoes several machining processes.
NC means "Numerical Control". They are the predecessors of CNC machines and are hardly ever used anymore due to their outdated technology. In NC machines, the data for machining a workpiece is stored on punched cards, which are placed in a punched card reader and read out. NC machines are not very flexible as soon as the machining process starts after the data has been read in. With CNC machines, you can still make minor changes and optimisations during the machining process.
Additional information is required to answer this question. This is because the machine throughput depends on various factors such as the type of drive or the area of application. For example, spindle motors travel approximately 0.2 mm per second, while linear motors achieve 2 - 3 mm per second.
CNC machines are powerful machines. Modern machines are controlled via an integrated microcomputer on which the required control programmes are created directly via a CAD/CAM system.
CNC machines are computer-controlled and receive the commands to move the various machining axes via a programme. This is created in CAD software and converted into a CNC programme using CAM software. This creates instructions that the machine can understand and execute correctly. The basis is a three-dimensional coordinate field within which the tools move according to the control instructions.
A CNC machine must be optimally adapted to the production requirements of a company. This applies to the material being processed, the dimensions of the workpieces and the functionalities. Equally important is the high quality of the various components, as these are exposed to high loads during operation. The software should be easy and intuitive to use in order to optimise the training effort. Alternatively, the manufacturer should offer a comprehensive training programme. Compatibility with various CAD software solutions is also important.
The drive systems of a CNC machine are equipped with ball screw drives or linear drives. Both have hardly any play, which ensures high precision during machining. The gantry drive is often used in portal milling machines. With this drive, two separate and angularly synchronised feed motors move a common drive axis.
Depending on the design, a CNC machine has two to six processing axes. The basic axes are the y-axis and the x-axis. The third axis is the z-axis, which often runs parallel to the work spindle. These axes are movement axes that represent the main axes. The remaining three axes are auxiliary axes that serve as rotary axes. The more complex a workpiece is, the more axes are required. The number of axes therefore always depends on the individual application.
