Resin Grinding Media

Product Introduction

Resin grinding media, also known as plastic polishing stones, are manufactured with high polymer resin binder mixed with precision abrasive grains. Compatible with trough vibratory finishing machines and eddy current polishing machines, they are ideal consumables for soft alloy and precision small parts.

We supply media with heavy, medium and light cutting power, grain sizes ranging from 80# to 2000#, and multiple shapes including cone, triangle, cylinder and tetrahedron to fit various irregular workpieces.

Key Advantages

1. Soft & scratch-free processing
   Elastic resin base delivers gentle cutting force. It prevents collision scratches on thin and delicate workpieces such as aluminum, zinc alloy, copper and plastic castings.
2. Good self-sharpening & long service life
   Worn resin surface exposes fresh abrasive grains continuously to maintain stable polishing efficiency. Low abrasion and less sludge reduce long-term production cost.
3. Multi-function one-step finishing
   Completes deburring, flash removal, chamfering, oxide layer cleaning and surface soft polishing in one batch process to streamline production.
4. Full range of sizes & shapes
   Diverse shapes and grits support matte, semi-gloss and mirror finishes when matched with polishing liquid. Separate processing is available on vibratory machines with removable dividers.
5. Chemical resistance
   Stable against acidic & alkaline polishing compounds, no cracking or pulverization during long-cycle automatic mass production.
