fascinating opportunities and a vast range of applications

The machines in detail:

Basic Series

Due to the reasonable price the Basic series especially attracts model makers and CNC-newcomers. It covers smaller to mid sized working areas an can be employed universally and flexibly. The machines of the Basic system are driven by stepper motors whose power is transfered to the axis via ball bearing mounted trapezoid threads. The drive system is largely covered and therefore well protected against dirt.

Precise Series

The Precice Series convinces with a solid construction and stronger motors. In addition the Y/Z-drive is protected from contamination by covered guideways. This ensures high precision and reliability in taily use.Tool- and reference switches are standard equipment of the Precise series. The cabling for the high speed spindle 160, for 230V/110V router motors and for triggering magnetic valves is protected by a cable drag chain. The Precise Series therefore provides ideal machines for industrial uses like processing synthetics, non-ferrous metals and wood.

Superior Series

Significant for the Superior Series are an extremely stiff construction with supported guideways and the backlash-free recirculating-ball spindles. The combination of this mechanic with high class hybrid motors and the highly resolving microstep-controll of the Xpert CNC controller box allow for extreme running smoothness - even at highest load with nearly all kinds of materials.

Whether 2½ or 3D - clean results, first class quality of edges combined with high operational speed and low maintenance requirements predestinate these milling devices for employment in the industrial area, resp. everywhere where high precision and fast processing at low running costs are required.

Controller Software

We offer two systems for controlling the machines, which are customizable by modular architecture:

StepFour Xpert is a Windows based system for professional use.
Essential merits of Xpert are: 3D 4-axis control, dynamic changeover between micro- and full-step operation... more

StepFour V4 uses DOS for generating the control signals and therefore is very reasonable. V4 software offers an obvious user interface and allows easy import of DXF, HPGL and other file formats...more

Modern design - constructive optimization - maximum protection against dirt

	Mechanism Due to the special construction with milled aluminum junctions and extruded profiles no base plate is required. The work area can be open underneath. The combination of slide bearings and tempered and reinforced steel shafts offers optimum damping and protection against injuries and dirt.
	Milling motors Depending on the application, various spindles up to a weight of approx. 2kg can be used e.g. standard routers with 43mm clamp (Metabo, Bosch, Kress etc. up to approx. 1000W), var. mini-routers such as Proxxon, Dremel etc., pneumatic or high-frequency spindles, and many others.
	Combined emergency-off relay box The box is simply inserted between the existing control electronics and the milling mechanism, thus creating numerous new possibilities. The machine including the motor can be brought to standstill extremly fast. This avoids wear and tear and prevents the router from breaking. The EC symbol guarantees high quality. Additional 220V devices can be driven without a problem. The PC directly regulates suction, the application of cooling fluids, the on/off function of a milling motor etc.
	Protective cell Ensures 100% safety and cleanliness in the work area. With the aid of an integrated door switch controlled by the emergency-off relay box, the machine switches off automatically as soon as the cell is opened.
