Technology & Products
Key Products
Abrasive Flow Polishing Machines (AFM); Thermal Energy Deburring Machines (TEM); Micro-particle Surface Nanization Treatment Machines (WPS); Micro-hole Polishing Machines (MF); Electrochemical Deburring Machines (ECM); Liquid Media Polishing Machines (LFM); Steel Bead Flow Deburring Machines (SFM); Flat Surface Grinding Machines (LPM); Robotic Deburring Centers (RDC); Grinding Media and Consumables
Technological Advantage
Proprietary abrasive media formulations and machine designs achieve Ra 0.1μm surface finish on 3D printed metal parts while maintaining ±0.01mm dimensional tolerance, verified through customer case studies.
Differentiation
Value Proposition
Reduces surface roughness of 3D printed parts by 99% (Ra 10μm to Ra 0.1μm) while maintaining dimensional accuracy within ±0.01mm, enabling direct production-ready parts without manual polishing.
How They Differentiate
Focuses specifically on post-processing for additive manufactured parts with complex internal geometries, unlike general surface finishing competitors; achieves 3x faster polishing cycles for internal channels compared to traditional methods.
