JUNG Rebuild JUNG REBUILD A machine overhaul at JUNG can be individually tailored to your requirements using our modular system. You can choose between individual assembly overhauls or have a complete rebuild of your machine. Here you can see a time lapse video of a JUNG REBUILD.

JUNG Rebuild Your rebuild options at JUNG Guideway overhaul During a guideway overhaul first of all the double V-guides of cross slide, table and bed (optional) are ground in relative to each other. The result is a perfectly coordinated machine geometry. The procedure is the same as for new machines (type H and J series). During this exclusive machining method a surface hardening takes place and the proven cross hatch finish (other fields of application: medical technology, automotive industry) is ground into the guides . But it is only the combination of guideway grin- ding and subsequent scraping...

Dresser overhaul Upgrades/retrofits Another of JUNG's core competencies is the dressing unit, which guarantees reliable contour accuracy. If signs of wear appear, you have the option of an overhaul. The dresser is restored to as-new condition. After disassembly all spare and wear parts are replaced and the guides are reground if necessary. The dresser is then reassembled and aligned by a service technician. Types: MA65, AF65/100, HF50, PA30/31/37/120/130 Duration: 2-4 weeks depending on type We are very keen to ensure that you are always kept up to date, without having to replace your machine's...
