Machining glass and ceramics, materials that are both hard and brittle, presents significant challenges. Unlike metals, these materials are highly susceptible to cracking, edge chipping, and thermal damage under machining pressures. Additionally, the process generates substantial amounts of fine dust and abrasive particles, which complicates the operation further. Standard cutting fluids used in metalworking do not provide the necessary protection and can lead to surface scratches, tool wear, and even coolant tank blockages if not chosen properly.

Because glass and ceramics are prone to cracking and edge chipping during machining, the need for specialized cutting fluids is crucial. These materials are especially sensitive to heat and pressure, so using the wrong cutting or grinding fluid can exacerbate surface damage and accelerate tool wear. The machining process also produces large volumes of fine dust and abrasive particles, which need to be effectively managed. Therefore, the right cutting fluid—one with rapid sedimentation, excellent lubricity, and high fluid stability—is essential to ensure optimal results
Using an unsuitable cutting fluid will quickly lead to：

• Surface Scratches & Reduced Yield: Recirculation of fine particles causes irreversible surface defects.
• Costly Downtime: Sludge solidifies in the tank, damaging pumps and clogging filtration systems.
• Accelerated Tool Wear: Insufficient lubrication rapidly degrades expensive diamond grinding wheels.

Fully synthetic cutting fluids, which contain no mineral oil, offer several benefits, especially for high-precision materials like glass and ceramics. These fluids provide outstanding stability, leave no sticky residues, and deliver clean, eco-friendly performance.

Glass machining is widely applied in optical lenses, camera modules, display panels, and other high-precision components. Due to the brittle nature of glass, improper particle management can lead to edge chipping, surface scratches, and rapid tool wear. Abrasive particles must settle quickly to avoid recirculation. Additionally, sludge buildup in coolant tanks increases maintenance costs and downtime.
👉 Key fluid requirements: Fast particle sedimentation and high sludge stability.

Machining ceramics like zirconia, silicon nitride, and IC substrates often requires water-based cutting fluids to control heat and extend tool life. While dry machining is common, certain processes depend on effective lubrication to reduce noise, sparks, and inconsistent finishes. Since fully synthetic cutting fluids contain no mineral oil, their performance hinges on additive quality and stability, making fluid selection critical for consistent results.

Why Sludge Control Matters in Precision Grinding Environments

Real cases from the field: hardened glass sludge that requires manual chiseling, a coolant pump encased in solidified sludge, and a discharge valve blocked by sludge buildup.

• EASY CLEANING: Simple sludge removal without intense manual scraping.
• REDUCED CLOGGING: Pumps and filters operate efficiently, reducing machine failure.
• OPERATOR SAFETY: The antibacterial, low-odor formula ensures a cleaner, healthier workspace, reducing the risk of skin irritation and respiratory issues.
