How to get perfect acrylic polishing effect?
Diamond polishing may look simple at first glance, but it is actually a complex system involving multiple interdependent factors. Key elements that determine the quality of a polished acrylic surface include the material of the polishing base, the rotational speed of the polishing pad, the grit size of the diamond abrasive, the type of polishing solution, mechanical positioning accuracy, operator technique, and the sequence of polishing cuts. Each factor can significantly affect the final mirror-like finish and edge bevel quality.
For hobbyist or occasional use, some of these factors can be overlooked. However, achieving a professional, high-precision result requires a systematic approach and strict control over each step in the process.
Professional diamond polishing is not merely a manual operation—it is a combination of science, engineering, and meticulous craftsmanship.
At Jinan Unique CNC Equipment Co., Ltd, our acrylic polishing machines and beveling machines are engineered to address these critical factors, providing users with high precision and consistent results:

Acrylic Blocks
- Polishing Base Material: We use high-precision granite or aluminum alloy bases to ensure flatness, stability, and vibration-free operation.
- Adjustable Pad Speed: Our machines feature variable frequency control to fine-tune polishing speed according to material thickness and type, optimizing surface finish.
- Diamond Abrasive Grit: Coarse to fine diamond powders can be easily switched, enabling a smooth transition from rough to fine polishing without damaging the surface.
- Polishing Solution Control: Integrated hydraulic systems and spray mechanisms ensure uniform distribution of the polishing solution, preventing scratches or surface burn marks.
- Mechanical Positioning Accuracy: High-precision ball screws and linear guides guarantee repeatable positioning, essential for maintaining edge consistency and mirror finish.
- Programmed Polishing Sequences: Machines can execute multi-step polishing programs, ensuring correct order of cutting surfaces and proper grit usage, which minimizes human error.
Additionally, our machines incorporate safety and efficiency enhancements such as automatic edge detection, real-time speed feedback, and vibration monitoring. These technologies allow even less experienced operators to achieve results comparable to skilled craftsmen.
In short, diamond polishing is not just a technique—it is a system where every component, from mechanical precision to abrasive selection, works together. By using professional-grade equipment like Jinan Unique CNC polishing and beveling machines, you can achieve consistent, high-quality acrylic surfaces while reducing manual labor and error.
Whether you are producing acrylic displays, signage, or custom parts, understanding these factors and leveraging advanced machinery ensures the best possible outcome.
