As the additive manufacturing industry continues to grow and evolve, so too does the need for high-precision post-processing technologies. One of the most critical stages in the 3D metal printing process is surface finishing—where accuracy, repeatability, and surface quality directly impact the functionality and performance of the final part.
DCM Rotary Surface Grinders, provide grinding technology for manufacturers looking to streamline post-processing while achieving unmatched surface precision.
What Are DCM Rotary Surface Grinders?
DCM Tech, Inc., a leader in surface grinding innovation, designs and manufactures rotary surface grinders specifically engineered for precision applications. These grinders use a rotary table to hold the workpiece, allowing for uniform material removal across complex geometries with minimal operator intervention.
With intuitive controls, robust design, and advanced automation features, DCM grinders are built to meet the demands of modern manufacturing environments, especially where tight tolerances, flat finishes and a clean work environment are required.
The Intersection of Grinding and Additive Manufacturing
In additive manufacturing (AM), particularly in metal 3D printing, components often require post-processing to meet dimensional and surface specifications. Technologies like Direct Metal Laser Sintering (DMLS), Electron Beam Melting (EBM), and Binder Jetting can leave parts with rough textures or slight warping.
Here’s where DCM rotary surface grinders come in:
1. Superior Surface Finishing
Achieving a consistent, high-quality surface finish is crucial for parts used in aerospace, medical, and automotive industries. DCM grinders offer a precise servo-driven z-axis and automated dressing, ensuring repeatable finishes ideal for tight-tolerance AM components.
2. Precision and Flatness
3D printed metal parts often require flatness corrections. DCM’s rotary technology ensures parallelism and flatness down to 0.0002, which is essential for assemblies and critical mating surfaces.
3. Reduced Post-Processing Time
Compared to manual lapping or belt sanding, DCM surface grinders significantly reduce labor costs and cycle times, allowing for higher throughput in additive manufacturing operations.
