Optimization of milling process:
Operating parameters:
Make sure that the electrode cutter was put into operation in accordance with the Article 7.
When optimizing the process, the focus must be on reliable welding quality based on
electrode durability with reduced resource and material consumption.
Results can usually be achieved when considering the following:
Table 1
Tool type
Cutting tools
1
Gun arm closing pressure measured on
the electrode while milling
0.7–1.3kN / 157.4-292.3 lbf
2
Rotations for new electrode
3-9
3
Rotation of previously milled electrode
3-6
4
Electrode shape
ISO or similar
5
Electrode material
CuCrZr, CuZr, CuCr, 160 Hb +/-15%
6
Welding assignment / sheet coating
0,5–7,0mm
7
Items of each part
20-150
* Values refer to electrode ø16mm, type F16 (ISO5821);
Different parameters are possible in varying cases, however, it can lead to significant
limitations of the milling results, the electrode service life, as well as increased tool and
equipment wear. Consult your technical advisor for additional support in these cases.
In these special cases the optimization investigation should start at the following average
values:
