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 cylindrical grinding machine takes ultra-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-size 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 surface 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 trouble-free production sequence, the machines are also equipped with automatic loading and unloading systems.

  • A Model Camshaft Grinding Process

    Optimizing a camshaft lobe grinding cycle has traditionally been based less on science and more on educated guesswork and numerous test grinds. Now, computer thermal modeling software can predict areas where lobe burning is likely to occur, in order to determine the fastest possible work speed that won't thermally damage lobes and greatly reduce the number of requisite test grinds.

    The double-disc grinding process is consolidating its position in automotive applications but is moving into other industries. Double-disc grinders are now easier to operate, and they have added capabilities for control flexibility, precision process control, faster changeovers, and grinding of nontraditional materials.
