Caution! Switch on the vacuum system. Bear in mind that the
vacuum filter might need be changed.
10.2 Operating the working depth limiter
Danger! Keep your fingers clear of the machine's traverse range
during operation.
It is particularly important that you keep the milling depth constant when
milling isolation channels in base materials which tend to be slightly
curved. LPKF ProtoMat C30 (C30/S) achieves this using the mechanical
working depth limiter.
This has following benefits:
• The depth limiter rides on the surface of the material. The
working depth limitercan follow slightly warped boards.
• The material is held down within certain limits by the working
depth limiter. The head is lowered by a solenoid actuator and
raised by a spring.

limiter
The milling depth is set by adjusting the knurled nut (2) on the working
depth limiter. Turning the wheel clockwise increases the milling depth
and also the milling width in the case of LPKF universal milling cutters
due to their conical shape.
Turning the wheel anti-clockwise reduces the milling depth.
The milling depth is altered by approximately 4 µm for each click of the
wheel. Turning the wheel anti-clockwise is easier than turning it
clockwise, particularly when the head is lowered.
