PMMA polishing machine AMI-C

for resinopticalindustrial

Overview
The AMI-C is BERMAQ's automated CNC edge polisher designed for finishing acrylic and methacrylate (PMMA). Available in two working lengths (2,100 mm and 3,100 mm), it offers a tilting head (-2° to +60°), automatic feed up to 10 m/min, and multi-part processing with 5–12 clamps depending on configuration. It machines straight edges and bevels with maximum thicknesses of 120 mm (straight) and 105 mm (45°). The patented BERMAQ® Buffing System and BERMAQ® diamond tools provide polished, smooth and transparent finishes.

Applications

• Acrylic and methacrylate displays: polishing of straight and beveled edges on thick panels for transparent finishes
• Visual communication and signage: letters, signs and three-dimensional elements finished in a single pass
• Stands / POS elements: acrylic and technical plastic parts requiring consistent surface finish
• Decoration and interior fit-out: custom panels, frames and separators with repeatable edge quality
• Series production of acrylic components: industrial finishing without extensive manual rework
• Jewellery and collectibles: small to medium parts with high-definition surface requirements

Technology

• Complete CNC control for numeric regulation of head angle, feed speed and cutting depth to ensure repeatable results
• Patented BERMAQ® Buffing System (optional/integrable): felt strip with polishing paste for final-pass gloss, smoothness and transparency
• Tiltable CNC head: automatic inclination from -2° to +60° to process straight edges, chamfers, bevels and complex geometries
• Original BERMAQ® diamond tools with integrated automatic cooling and lubrication to extend tool life and support continuous production
• Automatic workpiece feed and ability to process multiple parts simultaneously to optimize throughput

Materials

• Methacrylate and acrylic (PMMA): optical clarity and gloss
• Polycarbonate (PC): high-strength engineering plastic
• PVC: common signage and industrial components
• Alucobond®, Dibond® and composite panels: edge machining for technical and decorative parts
• Resins and other non-ferrous materials for specific applications
