Centreless grinding machines
JUPITER 200S - Centerless grinding machine
| 1600 x 3700 x 2200 | |
| 12.000 kg |
Productive all the way JUPITER series centerless grinding machines offer substantial production benefits: The patented CNC height adjustment of the support blade minimizes tooling times, automatic adjustment of the grinding gap geometry optimizes the grinding process and the inclined bed guarantees maximum dimensional precision. Depending on the application, corundum, CBN or diamond is used as an abrasive. Highlights - Rapid set-up due to patented CNC height adjustment of the support blade - Minimized undulations with grinding wheel balancing on two planes - Extremely low running noise due to grinding spindle with direct drive - Optimum grinding quality as a result of market-leading rigidity - Optimized grinding process due to automatic grinding gap geometry setting - Individual CNC dressing of grinding wheel and regulating wheel

Efficient grinding of ball screw nuts
Quality, cycle time, availability – the JUMAT external and internal cylindrical grinding machine leaves nothing to be desired.On ball screw nuts, the internal thread is pre-ground and finish-ground with a ceramic bonded mounted point in a clamping. Internal cylindrical grinding enables precise machining of the ball raceway.
Fast workpiece change times are achieved through the use of two workpiece spindles and non-productive times are reduced through cycle-time-neutral loading and unloading, including radial prealignment. Translated with DeepL

Unbeatable cycle time for complete worm shaft grinding process
The high-speed grinding machine JUMAT 2000 grinds single-start and multi-start worm shaft profiles from blank. The electroplated profile grinding, which is used for pre-grinding, enables a high cutting capacity and is ideal to process both soft and hard materials. During the subsequent finish-grinding with corundum, the gears are finalized. Thanks to the geometry calculation of the single-tooth grinding wheel, the grinding medium is perfectly designed for the thread profile of the workpiece.
If the worm shaft has specific surface requirements, a second grinding spindle with an additional polishing wheel is used. This three-stage process with an integrated deburring station facilitates the production of finished worm shafts in a single clamping process.
