Nano-Grinding for Mirror Finish Aluminum Sheet

Nano-grinding for mirror finish anodized aluminum sheet refers to the nano-scale high-efficiency grinding technology which mainly adopts the high-speed grinding processing method of fixed abrasive. It’s a newly developed process for surface treatment of mirror finish aluminum sheet and sheets of other metals. Fixed abrasive high speed grinding differs from conventional bulk abrasive grinding in that the density distribution of the abrasive is controllable. This feature of fixed abrasive grinding is reasonably used to arrange abrasive density distribution on the abrasive tool according to the relative motion trajectory density distribution among workpiece grinders. In this way the wear of the abrasive tool during the grinding process does not affect the accuracy of the abrasive surface, and the surface accuracy of the workpiece is greatly improved.
mirror finish aluminum sheet
In aluminum manufacturing industry nano-grinding is usually applied in ultra-precision grinding of single or double faces of mirror finish aluminum sheet, and it has obtained such a name because its processing precision reaches nanometer level. In planar fixed abrasive grinding, the rotary motion of the abrasive tool is the main motion, and the motion of the aluminum mirror sheet is the auxiliary motion. In most cases, the aluminum sheet is floating on the abrasive tool and its motion is unknown. Therefore, it is necessary to analyze the force of the sheet to determine its stress state and motion law. The motion law of the sheet can be obtained by taking it as the separation body of the whole grinding system and establishing the differential equation of its force balance. Successful mastering of motion laws of the abrasive tools and the mirror finish aluminum sheet under processing helps you to learn the relative motion between them and the relative motion trajectory density distribution. According to the distribution of the trajectory density of the aluminum sheet, you can design the abrasive density distribution on the grinding tool. In this way the abrasive tool does not lose the original surface precision after the wear, which ensures the surface accuracy of the aluminum mirror sheet.

Slitting of 1mm 2mm 4mm aluminium strip

图片
What kind of machine is used to make aluminum sheets into 1mm 2mm 4mm aluminium strip belts? Many people might think about a shearing device, but they are actually dealt with by a continuous slitting unit of a similar working principle to that of a shearing device. The difference lies in the point that there is no pause of shearing with a continuous slitting unit. Generally, the mother roll, namely, an  aluminum coil  to be slit, is placed. During the slitting process, the coil roll is divided into several belts which are further rolled into narrow aluminium strip rolls. The slitting method of both  1mm 2mm 4mm aluminium strip  or other aluminum strips can be divided into two types: a straight pull type and a loose sleeve type. The straight pull type refers to the method that aluminum strip rolls are kept in tension from being fed into the unwinding sail to being coiled by the coiling machine, and this production method is suitable for trimming and intermediate ...

The  diamond embossed aluminum sheet  refers to aluminium sheets with diamond patterns on the surface. In addition to 1000 series, 5005 and 3003 are frequently applied alloys as well. 5005  diamond embossed aluminum sheet s can be used for conductivity materials, cookware, instrument panels, electronic shells and building ornaments. Their anodized film proves to be brighter than that of 3003, and the color matches perfectly with that of 6063 aluminum alloy products. Generally speaking,  diamond aluminum checker plate s are sold by the unit of pieces. In international business the unit of metric ton is frequently used as well. Their thickness ranges from 1.7mm to 8mm, but those between 2mm and 7.75mm prove to be the most popular. The width is from 1010 to 1500, among which 1250 and 1500 are most frequently adopted. Embossed aluminum sheet s with different patterns usually match varied application scope. Five-bar and one-bar sheets are mostly used for anti-skid pu...

Embossed Aluminium Coil Patterns And Applications

图片
If you have ever used an escalator you might have noticed that there are partition panels respectively at the bottom and top of the escalator. These partitions are usually paved with  embossed aluminium sheet  coil that have a good pressure bearing capacity and are made of composite metals. As a matter of fact, there are various patterns and applications of embossed aluminium coil, and here we will give a simple introduction. 　　Patterns 　　Aluminum sheets with patterns on the surface is called embossed aluminum sheets or  aluminium tread plate . Pattern shapes include lentils, diamonds, round beans, and oblate mixed shapes. The market is most common in lentils. 　　Application 　　The aluminium tread plate has beautiful appearance, excellent anti-slip property, enhanced performances, and material-saving advantage in production. It is widely used in transportation, construction, decoration, equipment, floor, machinery, shipbuilding and other fields. Generally speaking,...
