PRELUB GP, the electronically controlled lubrication unit, is optimally matched to oil-air lubricated GMN spindles and guarantees a long service life.
The precisely regulated dosage of lubricant ensures effective bearing lubrication and maximum operational reliability during start-up and shut-down phases.
With its 4 connections (maximum), this lubrication unit is capable of simultaneously providing individual supplies to a maximum of 2 spindles while requiring only a minimum amount of space.
Connection to a conventional PC computer supports clearly comprehensible operation with a multi-lingual menu structure.
Accessory parts necessary for assembly, e.g. lubrication hoses, hydraulic and compressed air hoses, monitor manometer and filtered lubrication oil, are available from GMN.
1. Start pre-lube (enable signal to operate the spindle not issued)
2. Multiple lubrication pulses within a short time, depending on the length of line between spindle and mixing distributor (pre-lube cycle)
3. Enable signal following expiration of the pre-lube time
4. Transition to normal cycle (cycle time) according to GMN operating instructions
The length of the pre-lube period depends on the length of connected lubrication lines.
(Details: see operating instructions)
Filtration of the oil and air supplies are necessary to ensure the unit provides a long-term, consistent lubricating function.
The cartridges intended for a routine maintenance filter change are available from GMN.
The use of filtered oils with friction and wear reducing additives ensures long-term reliable operation of the spindle at maximum speeds.
Detailed specifications for the necessary lubricants as well as rules for cycle times and lubrication pressures are provided in the operating instructions included in the delivery complement.
Reducing the heat caused by operation and achieving maximum spindle performance depend on a reliable supply of coolant in the necessary quantity and at the proper temperature.
GMN cooling units ensure the precise coolant temperature and volume regulation necessary to obtain constant low operating temperatures.
Highly precise regulation accuracy reduces axial shaft elongations caused by temperature fluctuations of the coolant.
