GRINDSTAR machine concept from JUNKER
Replace turning with grinding in high volume production
The JUNKER GRINDSTAR offers an economical alternative to turning for small components ranging in diameter from 2 to 20 mm. Short cycle times and long tool life reduce piece part cost by up to 25% for batch sizes stating at 200’000. Its high productivity makes the GRINDSTAR an interesting alternative for high volume production in the automotive industry as well.
The innovative method includes grinding the entire workpiece contour in a single operation and more quickly, as grinding utilizes lower cutting forces than turning. Lastly, the GRINDSTAR allows for perfect coordination between the workpiece, abrasive, and machine. These factors harmonize to enable a significant increase in productivity. The GRINDSTAR is up to three times faster than a lathe.
