The parts of the Hobby A3 Advanced CNC Milling Machine are made of 8 mm thick aluminum, which, due to the small size of the machine, ensures the highest stability possible at the lowest possible cost and lowest possible weight. The work area of the machine is 300 mm for the Y axis and 200 mm for the X axis. The stroke of the Z axis is 70 mm. The clamping collar for the milling spindle can be raised to a maximum height of 80 mm over the work area. 

Hardened stainless steel precision shafts are used for the guide shafts of the machine. These precision shafts, in connection with friction bearings made of solid brass ensure maximum accuracy as well as a long lifespan and maintenance-free use.

The threaded spindles, with a thread pitch of just 1.5 mm per rotation, can get maximum force out of the motors, even out of apparently small step motors, and guarantee comfortable working. Thanks to these threaded spindles, the standard version of the Hobby A3 Advanced attains a positioning accuracy of 0.0035 mm at the maximum feed rate up to 600 mm / min. The Advanced version is also equipped with reference switches for all axes. This makes it easier to automatically position the tool, which makes it much easier to work when manufacturing small series. Furthermore, the powerful step motors of the Advanced version ensure double the axial force. 

The machine is basically intended for machining sheet materials. It is best to fix the sheets in place across the entire surface of the table using double-sided adhesive tape. This is the best method – this prevents the middle of the sheet from rising off the table, and the machined parts are not thrown out right away by the machine but stick to the tabletop instead. Small vises or other application-specific clamping devices can be mounted directly and easily anywhere on the tabletop by screws. The tabletop of the machine is made of a simple screen printing plate, which means it can be replaced when worn by a new plate at minimal expense. 

The control electronics were developed specially for these machines and are also manufactured in Germany. There are connections for limit switches, independent cooling, a relay for switching the spindle ON and OFF, and a slot for an expansion module (4 axis). The electronics are supplied with power by an external 230V adapter supplied with the unit.

The machine is controlled by a PC over a parallel interface (printer port) and any software operates using the clock signal / in the standard direction (CNC Easy, WinPC-NC, PCNC, Mach3, and many others). It is also easy to control the machine over a USB interface using the WIN-PC NC USB hardware and software. A large list of CNC software that can be used to control this machine can be found on our home page under the heading "CNC Software".
