Manufacturer's description

Mobilmet 440 Series are high performance, multi-service, non-corrosive straight cutting fluids designed for moderate to heavy duty cutting operations. Formulated from high quality base oils and chlorine-free additives, they deliver effective machining performance across a wide range of moderate to severe operations and are non-staining to both ferrous and non-ferrous metals. They are also suitable for machine tool lubrication and, in specific applications, as hydraulic fluids, and are formulated to prevent oil mist formation near the machine tool for a safer working environment. Mobilmet 446 (ISO VG 32) is recommended for severe duty gear hobbing, gear cutting and shaving, gear and thread grinding, milling, and broaching operations. It has a kinematic viscosity of 32.6 mm²/s at 40 °C, a viscosity index of 132, a pour point of -24 °C and a flash point of 190 °C (Cleveland open cup). Key benefits include multi-service versatility that reduces cross-contamination and maintenance costs, non-corrosive and non-staining performance for improved finished part quality, highly effective machining performance that extends tool life, improves surface finish and allows increased feed rates, and effective anti-mist characteristics for a cleaner, safer workplace. No formal specification or approval codes are listed on the datasheet.

Applications

• Mobilmet 440 Series fluids are recommended for a wide range of moderate-to-severe machining operations on all types of metals.
• Mobilmet 443 is recommended for machining non-ferrous metals and their alloys, and normal-to-difficult-to-machine steels, including cementation steels, carbon steels and high-alloy steels.
• Mobilmet 446 and 447 are recommended for severe-duty gear hobbing, gear cutting and shaving, gear and thread grinding, milling and broaching operations.

Performance & benefits

• Designed for a very wide variety of non-corrosive cutting and machining operations, ranging from moderate to severe.
• Provides long service life, improved tool life and lower reject rates.
• Multipurpose cutting oils, also suitable for machine-tool lubrication and as hydraulic fluids, helping minimise the effects of cross-contamination and reduce costs from unscheduled fluid changes or reduced machine/tool performance.
• Multi-service characteristics: reduced cross-contamination, less waste and lower maintenance.
• Non-corrosive / non-staining: improved quality of finished materials.
• Highly effective machining performance: longer tool life and reduced downtime, improved surface finish and fewer rejects, increased feed rates and machine speeds.
• Effective anti-mist characteristics: cleaner and safer working environment.
