How to maintain the Sheet Metal Prototyping bearings
Sheet Metal Prototyping is mainly used to process parts. And the bearing has decided that the bearing capacity of a machining center is good or bad, if the bearing performance is good, its load will be large load, so we have to do bearing the daily maintenance work, so as to maintain the performance of Sheet Metal Prototyping to keep the most Good state, extended bearing life. So how to maintain the Sheet Metal Prototyping? Then we look at the next:
1, the first bearing into the gasoline cleaning, wipe the residue in the bearing on the sludge and dust, all the rusty bearing with gold sandpaper gently wipe polished, until the hand touch no rough feeling so far.
2, with dry rags will be washed after the cleaning of the bearing, and then into the anti-rust oil soak. In this process, the bearings should be completely in contact with the anti-rust oil, and non-stop bearing, so as to make anti-rust oil film formed on the surface of the bearing, to achieve the purpose of rust.
3, followed by lithium grease and butter evenly coated on the bearing surface, including the inner and outer rings, wheels, cage. And is wiped around the edge of the bearing, so that the butter really into the bearing inside, play a full lubrication.
Sheet Metal Prototyping lubrication steps include bearings, gears, rails and top lubrication, different types of Sheet Metal Prototyping and the different conditions of the performance of lubricants have different requirements:
1, bearing lubrication:
(1), sliding bearing lubrication: sliding bearing is commonly used in transmission, lubricating oil not only to play the role of lubrication but also play a cooling effect, so the need for good lubrication with low viscosity lubricants, and need to have Good anti-oxidation, anti-wear, anti-rust and anti-foam. For precision grinding machine grinding wheel used in precision grinding bearings, due to bearing clearance is small (1 micron), the speed is particularly high (30000r / min or more) should use a very small viscosity, anti-wear oil excellent viscosity of 2.0mm2 (40 ℃) of the lubricating oil.
(2), Sheet Metal Prototyping Rolling bearing lubrication: Rolling bearings in the machine, due to the friction coefficient is small, and quiet operation, etc., and thus a large number of machine tools using rolling bearings, diameter 25mm, speed 30000r / min below, The More than 30000r / min, the application of forced lubrication or spray lubrication. It should be noted that rolling bearings in addition to large, rough special circumstances, generally can not use solid lubricants containing grease.
2, Sheet Metal Prototyping gear lubrication: the impact of the machine gear and vibration is not, the load is small, should generally do not need to use extreme pressure additives, lubricants. It should be noted that how to prevent the thermal deformation of the spindle box, the impact of a larger load stamping or cutting machine tool gears should be used with anti-wear agent gear oil, for circulation lubrication or oil bath lubrication oil, in addition to consider Anti-oxidation, but also take into account the anti-corrosion, anti-wear, anti-corrosion and anti-foam. Select the appropriate gear oil and the appropriate viscosity depending on the type of gear.
3, Sheet Metal Prototyping rail lubrication: rail load and speed changes greatly, the general rail surface load of 3-8N / cm2, but due to frequent repetitive rails, so prone to boundary lubrication, and even semi-dry lubrication Leading to crawling, in addition to machine design and poor material lubrication is the main reason leading to crawling. In order to overcome the crawling phenomenon, in addition to the use of fluorine resin guide veneer, etc., in improving the lubrication, the main use of anti-climbing agent lubricants, rail lubrication generally use viscosity 32,68,100,150 rail oil, BESLUXLUDER series (32,46,68,100,150,220) meet ISO6743 / 4 standard, L-HG level.
