| built: | 2008 |
| control: | SINUMERIK 840 D |
Our gear grinding machine RZ400 from Swiss premium manufacturer REISHAUER is a CNC-controlled gear grinding machine, which works according to the continuous generating grinding method with dressable, cylindrical grinding worms.
It is equipped with a counterholder and a NC tailstock with maximum center distance of 640mm for clamping shaft-shaped workpieces.
The two-spindle controlled RP160-2 dresser with 1.4 kW power is used for precise dressing of the mounted grinding wotrm wheels.
This very well maintained machine with only approx. 10,000 h operating hours from 2008 can machine spur and helical gears as well as spur shafts with cylindrical, crowned and conical (beveloid) external gears in highest precision.
