Numerical control machine tools follow specific instructions in the process of manufacturing a component. A software platform can control the position of a cut, as well as the depth of the drilled hole. Computer control is used when the respective component needs repeated drilling or tapping, certain parameters, such as depth, rapid travel forward or back and cancelling the control cycle.
CNC turning machine tools: are used to create complex shapes in metals and other solid materials. A part is fixed on the mobile table which guides the material around a stationary and rotating cutter or, vice versa, a cutter moves above a stationary table. Some of these also have an axle that can be moved around its Z axis, hence offering an adjustable cutting method. CNC milling machine tools: are often used for planning, drilling, routing, as well as cutting a slot. In addition, machines with Z axis can be used to create advanced 3D objects, such as embossed sculptures. Therefore, CNC milling machine tools can also be used for engraving projects.
Examples of CNC Machine Tools
CNC milling machines
Milling machines are CNC machine tools which use control elements for reducing different materials. They are capable of translating the programs created from a specific number and letters in order to move the axis to different locations and depths. Many CNC milling machine tools use G-code which is a standardised programing language recognised by many CNC machines, while others use languages created by their producers. These languages, often more simple than G-code, can’t be recognised by other machine tools. CNC milling machines have many functions, including front milling, shoulder milling, drilling, etc. The standard CNC milling machine tools have 3 axes (X, Y and Z), but others can also have one or more rotating axes. They can be successfully used in the advertising industry, but also in carpentry workshops. The engine of the milling machine has a water based cooling system. Its spindle speed can reach 24,000.
CNC turning machines
Turning machines are CNC machine tools that cut components while the latter are rotated. CNC turning machines can rapidly make precise cuts, generally by using correlation instruments and exercises. They are extremely efficient in complex programs for creating components which are much more difficult to produce with manual turning machines. CNC turning machines have control specifications similar to those of CNC milling machines and can often read G-code, as well as programing languages created by producers. Generally, CNC turning machines have 2 axes (X and Z), but the newer models have more axes which allow more advanced processes.

What businesses can benefit from the added value offered by CNC machines?
Main industrial engines for large series production (in industries such as aeronautics, automotive, energetics, etc.)
Mechanical processing factories, providers for industries in which they produce small series or unique components
Smaller workshops or maintenance departments of big factories, where they produce unique components and require high precision in certain situations
Benefits of CNC machine tools: rapidity, repeatability, precision control, human multitasking (an operator who works on more than one machine, interconnectivity and, the most important, is processing of complex surfaces – simultaneous 5-axis processing).
As a provider of complete technical solutions, Allmetech offers all clients maintenance services, repairs and spare parts, both in the in the warranty period and in the post-warranty period. The machine operation service after purchase is offered by Allmetech’s technical team.
The integration of numerical control machines in the available and functional industrial assemblies is one of our clients’ constant concerns.
Machine tools are mechanical processing machines for metal cutting which can be used separately (especially for unique components) or in production lines (especially for components produced in large series).
Machine tools can be easily connected with one another, but also in a robotised production line or supervised by an industrial computer with the help of the current computer-aided command and control systems.
