MODERN EQUIPMENT REVIEW Modern Machine Shop 137 SPOTLIGHT | Grinding McCormick Place | Chicago, IL | September 10-15, 2018| Booth# 236858 Corundum Grinding Machines for Serial Production Junker's Zema line of corundum grinding machines fulfill the requirements of serial production for a range of workpieces. The CNC machines grind elements such as flanges and journals on crankshafts as well as gear, turbocharger, and cardan shafts or spray nozzles with both precision and reliability. In total, the corundum line comprises three models, each of which has different areas of focus. The Numerika is designed for the series production of various workpieces as long as 3.5 m. The Kargo cylin- drical grinding machine takes heavy workpieces such as shafts weighing as much as 6 tons for generators or electric motors. Rounding off the Zema series is the Flexa corundum grinding machine, which is capable of processing as many as three grinding assignments with precision. The modular design of the series is designed for small- and medium-sized production runs, including internal, external and thread grinding. Whether grinding precision parts for vehicle engines or heavy shafts and axles, the machines are said to provide high-quality results. They come with a robust machine bed, hydrostatic guides and grinding spindles mounted on rolling or hydrostatic bearings. A user- friendly control system comes with all the necessary input masks for precision corundum grinding and sur- face quality. Designed for integration into production lines, the machines also come with a high level of automation. Several workpieces in a part family can be stored in the control system, enabling quick change-over from one workpiece to another in production. To ensure a trou- ble-free production sequence, the machines are also equipped with automatic loading and unloading systems. | Erwin Junker Machinery Inc. | 847-488-0406 junker-usa.com
