CNC MACHINE
This machine serves for drilling and routing PCBs and Aluminium and for isolation milling. It is fully equipped and easy to use. The extent of delivery contains the mechanics unit, the high frequency spindle, the integral control unit, a vacuum cleaner and the driver software for drilling and milling.
The axes are driven by stepper motors and precision belts. The step definition is 1 mil, the positioning accuracy is +/- 1 mil. The maximum speed is bigger than 90 mm/s. The control unit is hardware prepared to run the axes in microstep mode at down to 6.35µm step width. The Z axis as well has a stepper motor. Other the any solenoid or pressure cylinder drive, only a stepper motor allows active control over Z working depth and penetration speed. An additional mechanical depth limiter is included.
The machine comes with a high frequency spindle at 150 W and 60000 rpm. The tool change action is semiautomatic, with the driver software arresting the axes and prompting the user to change the tool. This is done right on the spot by a quarter turn of a knob, and no recalibration will discontinue the drill or mill job.
The machine table has a regular pattern of mounting holes where the board holders and clamps will go. The boards can be mounted to machine zero or to any relative position, but can be put on base plates with fixing pins, as required for double sided isolation milling.
The driver software coming with the machine will run on any standard PC. It directly reads Excellon or Sieb & Meyer drill files, or HP/GL. One software option is the RoutePro 2000 Windows 9x / NT based driver software, a second one is IsoCAM, a program that you will need to convert Gerber board data into isolation milling outlines. |
