The operating mode that degree of the structure according to the machine tool, automation, machine tool uses and the requirement to precision undertake be measuringed integratedly and the choice of the lubricant means of the machine tool and lubricant grease makes a decision, the machine tool is lubricant satisfying decrease grind fall bad news while want do one's best to avoid temperature rise and vibration. The machine tool serves as complex and accurate machine, can use varied gearing, the viscosity that environment of the sort according to equipment, work and ask precision requirement taste to lube, oily fight oxidisability, fight extremely press the dependency such as function to be able to have diverse demand. One, the requirement with lubricant machine tool: 1, the lubricant dot of the machine tool is much and complex, and a lot of machine tools lubricate at the same time, use more consequently lubricate automatically, also say compulsive loop is lubricant, in order to save labor power, assure to lubricate reliably. 2, the machine tool relies on fluid drive more, lubricate to simplify system, consequently a lot of machine tools are hydraulic pressure and lubricant system are common, should consider to want to satisfy each lubricating to order pair of lubricant requirements while it is normal to make sure hydraulic pressure system works consequently. Choose viscosity index as far as possible below the premise that considers moving cost tall, anti-wear properties can be mixed the lube with fight oxidation function good (fat) . 3, the slideway of the bed mixes stand-alone large scale computer of headstock lubricant, use gravity to cheer normally (dribble, oily core) lubricant means. With this kind lubricant means should consider the fluidity of lube, with making sure lube is OK and automatic inpour chafes deputy. 4, bed of large scale computer has a lot of positive drive device, slip with scroll bearing. Especially all-purpose grinder has very complex gearing, because attrition losing power achieves 30-40% , because this must consider when choosing lube proper viscosity is reached,fight goodly grind lubricity, of utmost of do one's best reduce attrition loss to be used up in order to save power. 5, rough machining machine tool is intermittent type job mostly, because this is met,companion has border to lubricate, should consider proper year, good lubricity to be able to be mixed so fight extremely control function. 6, the to lube temperature rise of accurate machine tool has very firm demand, cannot exceed ℃ of room temperature 2-5 commonly, the capacity of the viscosity that because this is right,oil tastes and lubricant means and gasoline tank should do careful consideration and design. 7, lubricant system, hydraulic pressure system reachs the machine tool to chafe individually deputy sealed and undesirable, the metal that can make treatment process medium grinds bead of bits, abrade pink to if arrive in lubricant system,be entered, not only the likelihood jams oil path causes the metamorphism that wears away to still can quicken oil to taste. Because this sealed to the system attention is necessary! 8, cooling, lubricant cutting tool and treatment workpiece are on metallic cutting, muller bed, use emulsion and the aqueous solution of natrium of 3 phosphoric acid that use on grinder to enter lube likely mostly, of stimulative oil demote metamorphism and emulsification. Because this is when choice lube,must consider what oil tastes fight emulsibility, be able to bear or endure water, antirust reach anticorrosion sex. 9, machine tool slideway is the key with lubricant machine tool and difficulty, the motion of slideway opposes double entry, and speed and load change are very big, appear easily creeping phenomenon, cause treatment loss of accuracy to bring about a machine tool to discard as useless even. The consideration wants early when choosing lube so proper viscosity and fight the lube with climb a gender good. 2, the machine tool lubricates and machine tool lube (fat) performance demand: Of the machine tool lubricant those who include bearing, gear, slideway and center is lubricant; Fat includes machine tool lubricating oil: Oil of hydraulic pressure oil, hydraulic pressure slideway and lube (fat) , the differs to taste to lube function of different machine tool sort and operating mode has diverse demand: 1, of bearing lubricant: 1) , of sliding bearing lubricant: Sliding bearing is commonly used transmission way, lube should remove lubricant action to have cooling effect even not only, because this needs to use the lubricating oil of the low viscosity with lubricant good performance, at the same time need is had fight oxidation, anti-wear properties, rust-preventing characteristic goodly to reach fight bubble sex. The accurate sliding bearing that uses to the place of holystone main shaft of accurate grinder, because bearing space is special small (1 micron) , rotate speed is particularly high (30000r/min above) should use viscosity very small, fight grind oily and wonderful viscosity for 2. 0mm2(40 ℃ ) lube.
Of bearing of 2) , scroll lubricant: Scroll bearing is on the machine tool, because have coefficient of friction small, run quiet wait for an advantage, scroll bearing already was used in great quantities on the machine tool consequently, internal diameter 25mm, when rotate speed 30000r/min is the following, usable seal high speed fat. When exceeding 30000r/min, criterion application lubricates compulsively or sparge lubricates. Those who need an attention is to roll bearing divides large, coarse special situation, cannot use the fat that contains solid lubricant commonly. 2, of gear lubricant: The concussion of the gear of the machine tool and vibration are not big, bear is lesser, answer and do not need to use commonly contain extremely the lube that presses additive. Those who need an attention is how to prevent the heat of main shaft box to be out of shape, pound the punch with bigger negative charge or the gear that cut a machine tool, should use contain fight the gear oil that wears a lotion, use at the gear oil that the loop lubricates or oil bath lubricates, besides should consider to fight oxidisability, even attend to is fought corrode, fight grind, antirust corrode reachs the sex that fight bubble. Choose appropriate gear oil and appropriate viscosity according to the sort of gear. 3, of slideway lubricant: The bear of slideway and rate change are very big, the bear of general slideway face is 3-8N/cm2, but undertake often iteration athletic as a result of slideway, because this is easy generation is attrib border and lubricant, work to lubricate and cause creeping appearance partly even, be designed besides the machine tool and data is lubricant and bad it is the main reason that brings about crawl. To overcome creeping phenomenon, except the department that use fluorine colophony slideway sticks a face to wait, improving lubricant aspect, basically use contain prevent the lubricating oil that climbs an agent, slideway lubricates to choose viscosity commonly 32, 68, 100, the slideway of 150 is oily, series of oily BESLUXLUDER of Spanish eagle slideway (32, 46, 68, 100, 150, 220) accord with ISO6743/4 standard, l-HG level. 4, machine tool tip is a kind of special bearing. Fixed and top negative charge is not big, high speed machine tool uses circumgyrate center more now, answer negative charge is bigger, because this is used,seal grease to lubricate. CNC Milling
