With a focus on detail-driven design, this machine integrates innovative structural features, high-performance components, and user-friendly functions to deliver exceptional grinding results. It achieves a workpiece surface parallelism of 0.008mm/300mm and surface roughness of Ra0.63μm, making it ideal for industries requiring high flatness and precision. Whether for heavy-duty grinding or micro-feeding tasks, the M7180 Series stands out as a reliable solution for automotive, mold, and precision machinery sectors.
Key Features
Anti-Plagiarism Structure Design for Superior Rigidity
The bed features a unique flat-V shaped guide rail with 7-plane contact, paired with PTFE guide rail strips for reduced wear and enhanced rigidity. The carriage is crafted from HT300 cast iron with a closed box-type dense rib structure, and its dovetail-shaped transverse guide rail (4 bearing surfaces) delivers unmatched vibration resistance and running accuracy—outperforming conventional designs.
Precise & Controllable Motion System
The worktable is hydraulically driven, enabling non-crawling operation at 3m/min for effortless tool setting. The grinding head cross movement offers two options: heavy-cutting (AC motor + synchronous belt + ball screw) and standard (hydraulic drive), both supporting accurate micro-feeding and groove side grinding. Manual fine-tuning sensitivity is optimized for precision.
High-Performance Core Components
Equipped with NSK precision angular contact ball bearings, the grinding head delivers exceptional vibration resistance and longevity. Both the worktable and carriage are made of HT300 cast iron, ensuring thermal stability and long-term reliable operation—from material selection to craftsmanship.
Humanized Hidden Technologies
The heavy-cutting model includes automatic lubrication with a low oil level alarm, while the standard model features forced lubrication for longitudinal guide rails. The cooling system uses two-stage filtration, and the ergonomically centralized electrical button box enhances operability. These details ensure durability and convenience.
