Quanzhou Tianli Abrasives Co., Ltd., dedicated to the field of precision processing for plastics and composites, is proud to introduce the Turbine-Shaped Blue Dry Grinding Disc (Specialized for Plastics and Composites)—a professional dry grinding tool specifically developed for surface treatment of non-metallic materials such as plastic products, fiberglass, and carbon fiber composites. This product breaks through traditional grinding disc designs by adopting a unique turbine-shaped structure and a highly compatible blue abrasive system, explicitly targeting challenges like plastic melting and composite delamination. It achieves efficient grinding, precise temperature control, and damage-free surface finishing, making it an ideal choice for scenarios such as plastic part trimming, composite surface refinement, and model processing.
Dynamic Heat Dissipation for Precise Temperature Control: The turbine blade’s aerodynamic structure forms efficient airflow channels. During grinding, it accelerates air circulation to rapidly remove heat generated by plastic abrasion maintaining the working area temperature within a safe range to prevent material softening, adhesion, or surface scorching.
Powerful Chip Removal to Prevent Clogging: The unique turbine airflow path not only cools but also continuously removes plastic grinding debris , keeping the grinding surface clean. This reduces issues like abrasive dulling caused by debris accumulation or surface scratches on the workpiece.
Edge Reinforcement for Precision Trimming: The outer edges of the turbine shape are specially reinforced to handle complex edge areas of plastics and composites with enhanced accuracy. It excels at refining sharp corners, burrs, and mold flash on plastic parts, as well as uniformly grinding layered regions of composite materials.
Low-Heat Generation Abrasive: Utilizes a specially formulated synthetic resin abrasive (not traditional metal or corundum abrasives) with moderate hardness and “self-sharpening” properties. During grinding, the edges of the abrasive particles micro-fracture autonomously, continuously exposing fresh, sharp surfaces. This ensures grinding efficiency while minimizing plastic melting/adhesion caused by high-friction heat (common in heat-sensitive plastics like PVC or PA).
Multi-Tool Adaptability: Compatible with common handheld electric/pneumatic tools such as angle grinders (4-inch/4.5-inch/5-inch/6-inch), straight grinders, and pneumatic grinders. Supports standard 1/4-inch and 5/8-11-inch bore sizes, enabling immediate use without additional adjustments.
Multiple Size Options: Available in 4-inch , and other specifications to meet diverse workpiece dimensions and processing requirements.
Long-Lasting Performance: Constructed with a high-strength resin matrix and wear-resistant abrasive layer, laboratory tests show that a single disc can last 2-3 times longer than conventional plastic grinding discs when continuously grinding plastic. For composites, the fiber damage rate is over 50% lower than industry standards.
The pure dry grinding feature eliminates cooling fluid contamination, while the blue abrasive layer intuitively indicates its professional purpose. Coupled with low-dust design and gentle grinding characteristics, it significantly reduces operational risks, allowing even beginners to quickly master its use.
