5.5.14.1 Special multiple plunge grinding program (optional))
This special program combines plunge grinding (either reciprocating plunge grin-
ding or creep-feed grinding) with reciprocating surface grinding and the corres-
ponding dressing cycles. The plunge grinding operation roughs the workpiece and
the reciprocating surface grinding operation finish-grinds it.
Advantages of the program
This special program benefits from the high cutting performance of plunge grin-
ding and the good surface quality of reciprocating surface grinding as well as of-
fering optimum machining times.
General functional description
• First program step (roughing):
– Depending on the width of the surface to be machined and the effective
width of the grinding wheel, several parallel recesses are plunge-ground in
order to cut as much material as possible within a short period.
• Second program step (finish-grinding):
– The machined surface is then reground in a reciprocating surface grinding
cycle in order to achieve the optimum surface quality.
You can assign the appropriate dressing technology to each of these program
steps.
Activating special multiple plunge grogram (optional)
• Press the "Special programs" softkey" in the "Machine Jung" module..
When you set the actual values for grinding (see section 5.4.4
“ISetting actual values for grinding” on page 117) the system auto-
matically activates only the "front" wheel edge.
Please refer to the "Machine Jung" module for the structure of the
function tree (see section 5.1.3 “Function tree structure of the
Machine Jung module in automatic mode” on page 75).
If your machine has two or more special programs, you will now see
a selection screen. When it appears, press the "Multiple plunge
grinding" softkey.
