Stages in milling and drilling
48 ProtoMat 95s/II
Note: Very thin base material may be secured with spray adhesive
to ensure perfect flatness
It is important that no adhesive tape, drilling or milling swarf is left
between the individual layers to ensure that the base material lies
absolutely flat. Small particles under the base material have an adverse
affect on the uniformity of the milling depth.
Caution! Switch on the vacuum system.
Bear in mind that the vacuum filter might need be changed.
7.2 The mechanical 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 are often slightly
curved. This is achieved by the pneumatic working depth limiter on the
LPKF
ProtoMat
95s/II.
This provides the following benefits:
1.
The working depth limiter works on a non-contact principle since
the compressed air escapes on the underside and causes the
working depth limiter to move on an air cushion.
2.
The depth limiter rides on the surface of the material. The working
depth limiter follows warped PCBs.
3.
The material is held down within certain limits by the working depth
limiter. The head is raised and lowered pneumatically.
