EMAG EMAG SN 320

The EMAG SN 320 is the largest machine in EMAG’s SN Series of CNC out-of-round grinding platforms, built for production grinding of the largest camshafts, eccentric shafts, and non-circular profile components in industrial, marine, and power generation applications. With capacity for workpieces up to 640 mm in diameter and 2,000 mm in length, the SN 320 handles workpieces that no other machine in the SN family can accommodate — large marine diesel camshafts, power generation engine cams, and heavy industrial eccentric components.

The machine provides 500 mm of X-axis travel and 2,700 mm of Z-axis travel, with hydrostatic guideways in all linear axes and a hydrostatic leadscrew drive in the infeed axis. This full-hydrostatic architecture is the same proven technology used throughout the SN Series, scaled up to maintain the frictionless axis motion and zero reversal error needed for accurate out-of-round profile grinding on large, heavy workpieces that amplify any vibration or positioning error.

The 640 mm maximum workpiece diameter — nearly double the SN 310’s 360 mm capacity — accommodates the large-diameter cams and eccentric components found in low-speed marine diesel engines, natural gas compressors, and heavy-duty industrial machinery. The 2,000 mm workpiece length handles the longest camshafts in production, including large V-configuration marine engines and multi-cylinder locomotive diesels.

The modular design supports various workhead, tailstock, and grinding wheel configurations customized to the specific application. Multiple grinding wheels can be positioned along the 2,700 mm Z-axis for simultaneous multi-lobe grinding operations. Both corundum and CBN wheels are supported, though the choice depends heavily on the specific application.

New EMAG SN 320 machines typically price between $900,000 and $1,500,000 depending on configuration, spindle count, and automation level.
