6.7 Manual milling
Every individual tool for the PCB production must be clamped into
the mill/drill head manually, if a circuit board plotter without
automatic tool change function is used.
For the process “manual milling“ the milling tool has to be inserted into the collet
chucks of the mill/drill head. The mill/drill head will be moved to start position
and then the motor is to be started. Afterwards the mill/drill head is lift down and
the milling track will be accessed. The milling depth is adjusted automatically.
The production result depends directly on the depth of penetration of the used
milling tool. An insufficient material removal between the PCB tracks may cause
malfunctions of the printed circuit board. For the conical milling tools like
UniversalCutter and MicroCutter the milling depth is determinate by the depth of
penetration of the milling tool.
Always mill a test track on the PCB material and check the milling depth using a
measuring microscope. Change the milling depth setting if required and repeat
the milling process until you have the correct result.
By using the milling depth limiter the depth of penetration can
be adjusted in 2 µm steps until the exact result has been
reached.
Health hazard caused by fine particles and gases!
During machining process of work pieces harmful fine particles
and gases may occur which can be inhaled!
Make sure that the dust extraction is activated during machining
of the work piece. Be sure to use fine particle filters exclusively.
Risk of injury by burning!
During the machining process the used tools and the collet
chuck heat up, direct contact may cause burnings.
Wear protective gloves and tweezers for manual change of
tools during operation.
