cnc bench polishing machine 3d model

Fully parametric CAD-style 3D model of a compact CNC bench polishing machine optimized for FDM 3D printing and modular mechanical assembly. Designed to polish ceramic pieces with minimum dimensions 200x200 mm. Industrial prototype with clean engineering mechanical topology. Large transparent acrylic top enclosure with hinged lid and silicone gasket seal, thickness 8–12 mm, fully enclosing the entire work area and water system. Clear lucite/acrylic panels on all sides and top. Reinforced base, modular printable sections for FDM, bolt assembly points for M4 and M5 screws, adjustable leveling feet. Work table usable area minimum 250x250 mm with 2-degree forward inclination and integrated perimeter drainage channels leading to lateral drain. X-axis travel minimum 300 mm with dual linear rails and ball screw drive, properly aligned bearing blocks. Y-axis travel minimum 300 mm under table with ball screw and stepper motor. Z-axis travel 120 mm with linear guides and lead screw, with suspended spindle motor 500–8
