Jig grinding – Fundamentals
Application
Jig grinding means grinding of a 2D contour. There is not much of a difference between jig grinding and milling. Instead of a milling cutter, a grinding tool is used, such as a grinding pin. Machining is performed in milling mode (i.e., with FUNCTION MODE MILL).
Grinding cycles provide special movements for the grinding tool. A stroke or oscillating movement, the so-called reciprocating stroke, is superimposed with the movement in the working plane.
