Castril SYNTILO CR 68
Synthetic Carbide Grinding fluid
Description
Castrol SYNTILO CR 68 is a synthetic metalworking fluid formulated especially for the grinding of cemented
tungsten carbide. SYNTILO CR 68 is a water extendable lubricant that prevents the leaching of the potentially
allergenic metal, cobalt, while providing exceptional lubricity and long-term biological stability.
SYNTILO CR 68 improves the appearance and mechanical properties of the workpiece by reducing the amount
of cobalt dissolution from the binder matrix of cemented carbide. The cost of waste treatment is also greatly
reduced because heavy metals are not dissolved during the grinding process.
Advantages
• Free from allergy and eczema tendencies
• Low consumption rate
• Reduced waste treatment costs
• Improved workpiece properties
• Economical to use
• Good foam control
• Low residues
