Erwin Junker Machinery Inc.’s Grindstar grinding machine offers an alternative to turning when manufacturing components with a diameter of between 2 and 20 mm. From batch sizes of 200,000, short cycle times and a long workpiece service life can drive down costs per workpiece by up to 25 percent, the company says.

This grinding method enables the entire workpiece contour to be ground in a single processing operation and involves much lower cutting forces than those occurring during turning. Another advantage is the coordination it allows between workpiece, abrasive and machine.

According to the company, the grinding machine achieves an availability level of over 96 percent and an extended tool service life due to every work step being covered in a single machine enhancing process reliability and minimizing machine downtime.

The manufacture of burr-free parts during grinding is guaranteed, the company says. Unlike turning, no chip impressions are created.
