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.



Precision Saw – IsoMet® 5000 Precision Saw 5000 11-2775 (Buehler GmbH)

The IsoMet® 5000 Precision Saw was designed for cutting various material types with minimal deformation. The positioning of sample in 2 micron step allows precise sectioning of specimens. User selectable feed rate allows an ultimate versatility. Enhanced software options enable 55 programmed methods and automatic serial sectioning as well as the ability to mount cup grinders for automatically grinding to depth.

  • Maximum dimension of samples 150x50x13mm (cross-section 50x13mm), or diameter 50mm
  • Cut thickness 0.667mm
  • Irregular samples can be fastened in a holder, which enables fixing of sample with cross-section ca. 30x30mm
  • Samples with approximately parallel sides can be fastened into holders with inner diameter of a cross-section 35 x 50mm or 35x11mm
  • Holder for glued samples with dimension 63×43 mm
  • Water-cooled saw
