In mass production, standard machines and abrasives often fail to deliver ideal finishing results. Common defects include hazy matte surfaces, micro scratches on soft alloys, yellowing and blue discoloration caused by dry friction heat, excessive dust and rapid abrasive breakdown. Traditional universal polishing wax or general tumbling oil cannot solve these problems effectively. Universal consumables are mainly designed for wet grinding or manual buffing, lacking targeted lubrication and high-temperature protection for closed dry tumbling environments. Improper auxiliary agents often cause residue adhesion, difficult cleaning and uneven coloring, failing to meet mass-production standards for hardware, medical devices, zinc alloy die-castings and titanium alloy parts.
Based on years of dry burnishing machine manufacturing and process debugging experience, Chengyuan Machinery developed exclusive formulas rather than adopting generic polishing compound solutions. A complete product series including CY-20, CY-28 and CY-58 covers rough grinding, intermediate finishing and super bright finishing stages, specially formulated for stainless steel, zinc alloy, aluminum alloy, titanium alloy and high-temperature alloys.
Chengyuan dry burnishing compound is a multi-functional composite auxiliary material integrated with high-efficiency lubricating components, active brightening agents, high-temperature anti-oxidation elements and micro-fine grinding ingredients. It perfectly adapts to water-free closed tumbling environments and forms a matched technical system with Chengyuan’s dry burnishing machines and abrasives.
3.1 Effectively suppresses thermal oxidation and surface discoloration
Dry burnishing generates continuous friction heat during operation, easily causing yellowing, blue tempering marks and foggy surfaces on titanium, aluminum and high-temperature alloy parts. Chengyuan special compound forms a uniform protective lubricating film during tumbling, isolating high-temperature oxidation and ensuring consistent color and texture across the entire batch.
3.2 Improves surface fineness and enhances gloss uniformity
The compound evenly coats abrasive surfaces to reduce rigid scratching and friction damage. It realizes flexible micro-leveling to fade fine tool marks, grinding lines and surface irregularities. Workpieces obtain uniform, delicate and consistent matte or semi-bright surfaces, effectively reducing or eliminating manual re-polishing procedures.
3.3 Reduces abrasive wear and dust generation
Pure dry friction without compound causes rapid abrasive fragmentation and excessive workshop dust. The lubricating formula of Chengyuan compound buffers abrasive collision, slows down abrasion consumption, reduces dust emissions and extends the service life of grinding media, greatly lowering long-term consumable costs.
3.4 Multi-alloy compatibility expands process application range
Different customized formulas effectively solve common processing difficulties for various materials: preventing over-polishing and edge erosion on zinc alloy die-castings, reducing thermal damage on titanium alloys, and improving surface compactness and corrosion resistance on stainless steel parts. It significantly enhances plating, PVD and coating adhesion for subsequent surface treatment.
3.5 Stabilizes batch consistency for automated mass production
The compound supports quantitative and standardized dosing. Cooperating with fixed machine speed, processing time and compartment loading parameters, it delivers highly repeatable finishing results. It eliminates quality fluctuations caused by manual experience differences and greatly improves finished product yield for large-scale automated production.
1. Select corresponding compound models for rough grinding or fine finishing; do not mix different formulas.
2. Strictly follow quantitative dosing standards. Excessive dosage causes sticky residue; insufficient dosage weakens brightening and lubricating effects.
3. Workpieces must be fully degreased before loading; residual oil will damage compound performance and cause staining defects.
4. Combine with scientific compartment layout and standardized machine parameters to achieve optimal finishing performance.
Dry burnishing quality relies on a complete technical system rather than merely equipment investment. As an original supporting consumable independently developed by Chengyuan Machinery, the special burnishing compound fills the technical gap of professional dry grinding auxiliary materials. It effectively solves industrial bottlenecks such as foggy surfaces, color difference, thermal oxidation and fast abrasive loss. By upgrading overall surface quality, stabilizing batch consistency and reducing rework rates, Chengyuan’s professional compound enables higher-efficiency, higher-quality and more cost-effective dry burnishing mass production for hardware, medical equipment, automotive parts and die-casting industries.
