In the world of highvolume manufacturing and rapid prototyping, CNC machining stands as a pillar of modern production. It efficiently creates complex parts with impressive accuracy. However, for components where absolute perfection in form, fit, and surface finish is nonnegotiable, the journey often doesn't end at the CNC machine. This is where precision grinding becomes the critical final step, transforming a good part into a flawless one and adding significant value to your project.
While 5axis CNC milling can achieve remarkable tolerances, it may leave behind microscopic tool marks and slight dimensional variations. Precision grinding, utilizing a rotating abrasive wheel, addresses these limitations headon. It is the definitive process for achieving:
UltraTight Tolerances: Grinding consistently holds tolerances within ±0.0002 inches (±0.005mm) or even tighter, which is essential for applications in aerospace, medical devices, and optical equipment.
Superior Surface Finishes: This process can produce surface finishes that are exceptionally smooth, often achieving 8 Ra microinches or better. This reduces friction, improves wear resistance, and enhances the part's performance and longevity.
Exceptional Flatness and Geometry: When a part requires perfect flatness, squareness, or parallel surfaces—such as for machine tool slides, gauge blocks, or sealing surfaces—grinding is the unequivocal solution. It can also create very sharp corners and precise profiles that are challenging for milling alone.
The synergy between CNC machining and precision grinding in a single workflow is a powerful advantage. Our company leverages this integrated approach to deliver components that meet the most stringent specifications. We first use CNC machining to efficiently create the part's core geometry from materials like hardened tool steels, carbides, ceramics, and highperformance alloys. The part then moves to our grinding department, where skilled technicians use surface, cylindrical, or centerless grinders to refine critical features to their final, exact dimensions and mirrorlike finish.
