Description
Castrol Magna™ SW D 220 (previously called Magnaglide D 220) is a high performance demulsifying slideway lubricant type CGLP (ISO VG 220) for machine tools.
Magna™ SW D 220 is based on powerful extreme pressure and lubricity additives in highly refined mineral oil offering constant glide behaviour, excellent adhesion and wear protection as well as excellent corrosion protection and ageing resistance.
Application
- On all horizontal and vertical slideways where a high quality demulsifying lubricant is required for slideway protection and to maximize coolant life.
- Magna SW D slideway oils are noted for their usual ability to overcome the stick-slip motion ordinarily associated with slow moving tool parts.
- They reduce machine tool carriage chatter and possess the necessary adhesive characteristics to prevent squeezing out of the lubricant.
- Magna SW D covers the exacting demands in the following applications:
- Planers, grinders, horizontal boring machines, shapers, jig borers, and milling machines
- Especially suitable for plastic coated guideways. (Possible swelling of the plastics won’t occur like it can with the use of conventional, non-demulsifying slideway oils)
Specifications / Approvals
- DIN 51502 (CGLP)
- DIN 51524-2 (HLP)
- Fives Cincinnati P-50
Advantages
- Excellent demulsification and metalworking fluid compatibility help to prevent soluble oil emulsions on slideway surfaces and to keep the coolant in clean conditions
- High load carrying capacity prevents wear of highly loaded slideways and prolongs the life of machine parts
- Exceptional frictional characteristics prevents stick-slip. This provides high tool slide working accuracy and repeatable machining so that high quality surface finish and tolerances are maintained at low rejection rate levels
- Protects metals against staining and corrosion which keeps oil-wetted surfaces in good condition and avoids downtime and expensive slideway repair or replacement
- Very good filtration property keeps filters in oil supply unblocked
