Machine running without bearing, bearing require constant maintenance and maintenance, in order to better work.
Because of air pollution in some plant, dust is very big, plus had lubricating oil bearing body, dust sticky on the bearing, not to be clear on time, as time passes can form agglomeration, so as to increase the friction, serious can cause wear bearing and mechanical equipment.
This time, will in time for polishing.
Today, we in spindle bearing, for example, talk about polishing machine tool spindle bearing.
Polishing operation must pay attention to some problems: 1, the polishing must be conducted in clean dust-free indoor.
Because hard dust pollution of grinding material, mold surface damage is nearing completion.
2, each polishing tools to use only one level of polishing diamond paste, coexist in dust or sealed container.
3, no. When it comes to convert a finer level of sand, to pay attention to whether the class number sand completely cover at the next higher level,
Coarser)
Sand grain, must wash your hands and artifacts.
4, start polishing processing before corners, edges and rounded corners are harder to polishing.
5, when dealing with sharp corners and edges should be especially careful, careful not to form a rounded corners, or rounded edges, should try to adopt a hard mold grinding and polishing tools oilstone grinding.
Polishing machine is composed of base, selling, a polishing cloth, polishing mask, cover basic components, etc.
At the same time also want to make polishing damaged layer does not affect the ultimate observed group, namely not cause false organization.
At the same time should also make sample rotation and move back and forth along the wheel radius direction, in order to avoid local wear too fast in the process of polishing polishing cloth to keep adding powder slurry, keep polishing cloth certain humidity.
Electric thought on the base, the fixed pads with the taper sleeve through screw connected with electric thought axis.
In order to achieve the purpose of rough cast, low rotary speed, had better not more than 500 r/min.
Polishing time should be longer than the time needed for removing scratches, because also remove deformation layer.
Polishing cloth by ring clamp on the pads, electric thoughts through the base of the switch power supply after starting, usable hand to pressure on the sample in the rolling polishing pads long.
Coarse behind the purpose is to remove the grinding damage layer, this phase should have maximum rate of polishing, the surface layer of rough cast formation damage is a secondary consideration, choosing also shall be as small as possible;
The second is the essence behind (
Or eventually throw)
, its purpose is to remove the rough surface damage, make the ultrasonic die polishing machine polishing damage to a minimum.
Polishing cover and the cover can prevent dust and other sundry on the machine when not in use on the polishing cloth and affect the use effect.
The best way to solve this contradiction is the polishing is divided into two stages.
Polishing machine control hub idea is to get the biggest polishing rate, in order to remove polishing when the damage layer as soon as possible.
Fine buffing wheel speed can be appropriate when progress, polishing time to throw away rough cast damage layer is advisable.
Above is the author introduce you polishing considerations of machine tool spindle bearing, you understand?
If you have any questions in the process of polishing, welcome you to come to consult.
The author warmth to remind you that in plant operation, it is important to note that all kinds of dust, so as to avoid inhalation lung body damage.
At the same time, bearing must be clean regularly, in order to prolong service life.
