Polishing machine Q&A
- The abrasive are small in size, with particle diameters ranging from 0.2mm to 0.6mm, allowing for precise treatment of any gaps, grooves, or special workpieces.
- The main component of the abrasive material is composed of elastic rubber, so there is no need to worry about affecting the dimensional accuracy of the workpiece during the polishing process.
- This abrasive material can withstand high temperatures of up to 250°C and is not easily worn during the polishing process. A 3-kgs abrasive material can be used for approximately 1,000 hours.
- This abrasive material is a dry abrasive, and after polishing, the workpiece can be simply blown with an air gun to clean the surface without the need for additional washing.
- There are no pollution concerns, as the spent abrasive material is reduced to powder and is collected by the equipment's dust collector. It can be disposed of as dry waste, without any difficult waste material disposal issues.
- The abrasive material is reusable and can be replenished as needed, eliminating the need to discard and replace the entire batch. This approach is both economical and efficient.
It is primarily composed of three components: elastic abrasives, diamond powder, and grinding fluid.
① The composition of elastic abrasives includes rubber. Its main function is to serve as a carrier for diamond powder.
② The primary function of diamond powder is grinding and polishing.
The primary method for distinguishing between coarse polishing and fine polishing of abrasives is mainly determined by the fineness of the added diamond powder.
In simple terms, if you add #10000 diamond powder to the same rubber particles, it is for fine polishing, whereas if you add #800 diamond powder, it's for coarse grinding.
It's important to note that using both fine and coarse diamond powders on the same batch of rubber particles can lead to a significant reduction in polishing effectiveness.
So, if you have both coarse and fine polishing requirements, it's advisable to prepare two separate batches of rubber particles. One batch should be for adding fine diamond powder, while the other batch should be for adding coarse diamond powder.
And each time you switch between coarse polishing and fine polishing abrasives, it's essential to completely remove the abrasives from the machine. Then, use compressed air to clean every nook and cranny in the machine's workspace, including any remnants of abrasives left behind in the machine's rear door.
③ The main function of the grinding fluid is to adhere the diamond powder to the surface of the elastic abrasive.
Only 10ml of grinding fluid is needed for each abrasive regeneration. Adding too much abrasive can lead to clumping and affect the performance.
① The consumption of elastic abrasives is mainly due to human use and natural wear. Overall, the consumption is very minimal.
The particle size of the abrasive is between 0.2 and 0.6mm. Only when it is worn down to below 0.1mm, it will be vacuumed away by the dust collector in the equipment. Therefore, natural wear and tear is very minimal.
The main source of loss is due to human factors, such as when the polished workpiece is not properly cleaned after polishing, during material unloading, or when changing materials, etc. These situations can easily result in abrasives being scattered outside the machine.
② Diamond powder should be added approximately once every 8 hours of operation. Before adding it, you should first remove the abrasive material and add around 5 grams of diamond powder.
③ The grinding fluid only needs to be added in an amount of 10ml for each abrasive recycling.
Under normal circumstances, each kilogram of rubber granules can be used for 300 to 400 hours.
When you clearly feel that the amount of sand is decreasing or when there are irregular fluctuations in sand output, it may be because the abrasives in the equipment have fallen below the minimum required amount for that equipment.
At this time, you only need to add as needed, there is no need to dump entire batch.
It varies depending on the metal material. It primarily depends on the initial condition of the product, the material, and the pre-processing steps.
In general, if the initial surface roughness (Ra) is 1.0, it can be reduced to below 0.5 through polishing.
If the initial surface roughness (Ra) is 0.2, it can be reduced to below 0.1 through polishing.
Yes, it will, so regular cleaning and maintenance are necessary.
The maintenance time depends on the customer's product situation.
For products with more burrs, it's best to perform regular cleaning and maintenance every week.
If the product has fewer burrs, maintenance once a month is sufficient.
Yes , it will . But the actual impact is very small. When the initial Ra (roughness average) is 0.5 micrometers, after polishing, it becomes 0.2 micrometers, and the size impact is 0.3 micrometers.
As this machine equipment is for jet polishing, there needs to be space to expel the abrasive when it contacts the workpiece. In the case of blind holes, deep holes, or hole diameters less than 5mm, it is not suitable.
