Resolution: 0.1 mil (= 2.54 micrometer)

Step definition: Software selectable: 1 mil, 1/2 mil, 1/4 mil (= 6.35 micrometer)

Easy to use teach-in feature for drill data

All machine parameters (speeds, acceleration ramps, X/Y/Z dimensions, scaling) software controlled and configurable

Fully integrated Windows (98..XP) driver software for Excellon, Sieb&Meyer or HP/GL data for real-time, on-line machine control, with comfortable user interface, including full tool management and plausibility control

Built-in control unit connects to all standard PCs with 1 free USB or serial port

Vacuum board fixation not recommended due to problems with board penetration by drilling

Possibility of mounting boards to machine zero point. Clamp fixing devices included with machine, span fixing for heavy-duty milling is possible

Board fixture by "fiducials" possible at no extra cost, using standard base sheet material

Uses all common PCB drills/mills with 1/8" shank, with industry-standard length setting by collar

Working depth not limited by depth sensor, only by tool flute length (standard: 5..10 mm)

Stack processing of several boards at once (typical stack: three 1.6 mm thick boards plus one underlay/base sheet)

Removable, spring-load pressure foot for drillng of flexible and uneven PCBs

Integral depth limiting device for isolation milling and engraving on uneven surfaces, work level setting by Z stepper motor, depth fine adjustment with micrometer screw

Max. hole diameter: infinite

Smallest tool diameter: 0.1 mm (micro end mill at 60 000 rpm)

Quick manual tool change by turning a knob, with machine position locked, no recalibration of height required

Standard travel area: 270 x 325 x 37 mm (larger machines available)

Always adequate cutting speed over the entire spindle RPM range, no need for 100 K rpm spindles, no excessive wear to costly spindle bearings

All X/Y and Z traverse speed, working speed, working depth, spindle rpm and depth iterations individually configured on a per-tool basis, resulting in:

Heavy duty 2x2 phase high-torque stepper motors on all 3 axes for true milling capability and correct tool speed

Spindle quick stop (1s) DC brake and speed-up booster

Software controlled spindle speed. Electronic spindle load control with software feedback

KaVo high precision spindle motor, 150 Watt, 60 000 rpm, with heavy-duty long-life bearings, including 1/8" (3.2 mm) chuck

Machine bed with universal fixture system, suitable for clamp or span fixing or for reference pins (fiducials)

Mechanics unit: rigid and flat construction with low moving weights and high quality bearings for high-speed positioning

Powerful 500-1500 Watt (adjustable) vacuum cleaner, remote controlled

Windows driver software RoutePro 2005 for drilling and routing

Integral depth limiter and pressure foot

Manual, semi automatic tool change, 99 out of 99 tools per job

High speed, long life spindle with quick stop brake and load control

Buillt-in control unit, full set of cables
