The CNC Eccentric Axis Polygonal External Grinder ODMP Series is a specialized machining solution designed to deliver high-precision results for complex workpieces. Equipped with proprietary grinding software, this machine simplifies operations while achieving exceptional accuracy in processing eccentric, polygonal, elliptical, and irregularly shaped components—making it ideal for industries demanding tight tolerances and consistent quality.
At its core, the CNC Grinder ODMP Series integrates advanced drive technologies: the X-axis utilizes a linear motor for rapid, smooth movement, while the C-axis features a servo direct drive with a circular grating to ensure precise rotational positioning. This combination minimizes backlash, reduces processing time, and enhances overall stability, even during high-speed grinding operations. Whether handling small batches or mass production, the ODMP Series adapts to diverse manufacturing needs, supported by compatibility with leading control systems (Fanuc, Siemens, GSK, Mitsubishi) for seamless integration into existing production lines.

The ODMP Series prioritizes durability and precision in its design. The bed is crafted from high-grade cast iron with a stress-relieved structure, minimizing vibration and thermal deformation during prolonged use. This robust foundation ensures consistent performance even in harsh factory environments.
The grinding wheel spindle features high-precision angular contact bearings, reducing runout to less than 0.0005mm—a key factor in achieving mirror-like surface finishes (Ra ≤ 0.02μm) on machined parts. Additionally, a built-in coolant circulation system with multi-point nozzles directs coolant precisely to the grinding zone, preventing overheating and ensuring chip removal, which further protects workpiece integrity.
The machine’s control panel is ergonomically positioned, with a 15-inch touchscreen display that simplifies access to the proprietary grinding software. The software includes pre-programmed templates for common workpiece shapes (eccentric, hexagonal, elliptical), allowing operators to set up jobs in minutes rather than hours. Safety features, such as a protective enclosure with interlock switches, meet international safety standards (ISO 13849-1), ensuring operator protection during high-speed operations.
The ODMP Series excels in machining:
Eccentric shafts: Used in automotive engines, pumps, and compressors, where offset rotational axes are critical for function.
Polygonal components: Including hexagonal bolts, square shafts, and splined parts for machinery and aerospace systems.
Elliptical workpieces: Such as camshafts and eccentric gears, common in precision mechanical transmissions.
Automotive: Machining camshafts, crankshafts, and transmission components with tight tolerance requirements.
Aerospace: Producing precision fasteners, hydraulic system parts, and engine components where reliability is mission-critical.
Precision Instruments: Manufacturing gears, valves, and measuring tools that demand micron-level accuracy.
Hydraulics & Pneumatics: Grinding eccentric cylinders and polygonal spools for hydraulic valves, ensuring leak-free performance.
The ODMP Series achieves a positional accuracy of ±0.001mm on the X-axis and ±2 arcseconds on the C-axis, with surface finishes as fine as Ra ≤ 0.02μm. These metrics meet the strictest standards for high-precision manufacturing.
