Every day the Nanotechnology youth innovation creativity centre is working on development of interesting, practically feasible and perspective projects. One of the most popular areas in the market today is the creation of CNC machines.

The long-term experience of the Advanced Technologies Center in the production of the FemtoScan scanning probe microscope, in which high-precision technology of three-axis positioning is applied, was transferred to the sphere of designing machining centers [1, 2]. So it was possible to create the first product in the line of machines – ATCNano three-axis CNC milling and engraving center.
Let's consider in more detail the main advantages of the ATCNano.
Small overall dimensions and weight. Due to the use of high-strength aluminum alloys, it became possible to create a compact and rigid machine with a working field of 150 Ч 120 Ч 80 mm. Optionally, the milling center is equipped with a protective casing with dimensions of 345 Ч 425 Ч 500 mm and with an emergency stop button. No additional equipment is required for functioning.
Precision mechanics. The basis of the concept of a mobile CNC machine was the achievement of high productivity. Therefore, ball screw transmissions and precision components of linear displacements made by the leading manufacturers of mechanical components (Hiwin, Giden Electronics, TBImotoin) are used. Ball-screw transmissions are mounted on precision radial-thrust bearings, and torque transmission is carried out by elastic couplings.
Modern management system and software. The latest developments in the field of software and control of CNC machines ensure the stability of the system in conditions of continuous operation. Together with an intuitive interface, this gives a competitive advantage in high-performance processing compared to obsolete control systems and heavy machine tools. Transmission of data packets to the control unit is carried out via an Ethernet cable to a PC-independent controller, which eliminates the system overload during complex processing operations.
Non-contact high-resolution limit sensors. Inductive sensors high resolution are used for calibration of the machine before work and limit the safe operating area.
Protection from processing waste on all axes. Corrugated protection prevents the penetration of chips and dust into the internal parts of components and engines.
Powerful spindle with air cooling. High-speed spindle (24 000 rpm) for ER11 collets with a power of 1.5 kW with programmable speed is designed for processing such materials as wood, plastics, soft metals.
Currently, ATCNano milling and engraving machining center is successfully used in Nanotechnology YICC to perform simple tasks for processing materials and manufacturing parts [3]. And, of course, we do not stand still and strive to improve the existing model, improving the accuracy of positioning. Our goal is to achieve nanometer accuracy. Thus, in the YICC, you can learn not only to create production, but also to make your own means of production.
Technical parameters of the ATCNano are presented in the table.
The development of modern nanoindustry puts forward new demands on production technologies. So, for example, in the field of machining, the most important task is to increase the precision of machining centers down to nanometers. Many parts and components of equipment for nanotechnology are characterized by high complexity with small dimensions. It is reasonable and economical feasible to manufacture such devices on compact machining centers. We made the first step in this direction. The original design of the ATCNano milling machining center is developed, which is distinguished by its small dimensions and high precision. ■
