In our home life, we can often see the marble figure. The characteristics of marble are natural and beautiful. However, natural marble has many unsatisfactory places. Therefore, it needs to be processed again. What are the special processing techniques for marble ? Let's have a look.
One, marble shaped processing skills
Usually there are eight main steps in the processing of marble shaped processing :
They are blanking, forming, grinding, repairing, polishing, chamfering, inspection and packaging.
1. The first step of special-shaped processing is to cut materials, and the materials must be carefully selected, for example, to find blocks with good texture and suitable size. Machines generally use disk diamond saws.
2, the second step is the formation, this means is the shape of the special-shaped marble stone processing. There are many contours of special-shaped stone, such as flower line, arc plate, three-dimensional sculpture, stigma and so on. There are a lot of equipment, such as advanced hydraulic profiling, photoelectric profiling, numerical control equipment, hand-grinding machines, horizontal lathes, vertical lathes, drills and so on. The tools used are diamond pattern grinding wheels, small-size diamond circular saw blades, diamond milling cutters, and diamond drill bits.
3. The third step is grinding, which means that the profile of the workpiece is refined and finely ground and coarsely ground again. The equipment is generally the same as the forming equipment. It utilizes the forming equipment, then uses a forming tool to turn it into a grinding tool, and some equipment uses a special grinding machine for machining. Then the complex shape of the workpiece using a small power tool for grinding.
4. In the fourth step, the polishing process is basically the same as the grinding process. The only difference is that the abrasive grain size used in the polishing process is relatively finer than the grinding process, and therefore the polishing rate is relatively large.
5. The fifth step uses chamfering and chamfering to process the faces that need to be assembled. For example, when using arc plates for assembly, double-knife disc saws are used to process them into fixed angles, and they are assembled into a circle. such.
6. The sixth step of inspection is to check the surface defects and glossiness using special-shaped stone dimension tolerances.
7, the last step can be packaged, generally using wood or plastic products for packaging.
The article concludes: We introduced the special processing techniques of marble for everyone. Have we learned more about the special processing of marble? Some of the marble processing steps can also be combined into one step, for example, some arc forming steps will Complete with the blanking steps. The special-shaped processing of marble can also be accomplished with modern equipment, such as CNC machining centers. This is very scientific and the speed is very fast. Many projects can be completed at the same time.
