Processing of ceramic and glass samples

Optical Profile Grinding Machine – JUNG JE 525 P (Blohm Jung)

The core competence of Karl Jung GmbH represents a process sure, µ-accurate surface and profile grinding of surfaces and tolerances. The special characteristic of machine is long-lasting, high geometric stability. The constructive body includes a cross table construction with diving column. Special ground double -V- guide slide bearings guarantee an exact and linear guidance with extraordinary properties of absorbability. Flexibility in the work shop can be provided only by quick and simple handling. The touch screen enables to setup and start the machine without complex handlings through function and soft keys. JUNG has invented the same technology also for dressing. Simple and practice oriented work piece contours like radii, bevels and curvatures can now be entered inter actively. At a push of a button the dressing programme for profile dressing of the grinding wheel is provided.
