Modern stone processing has supporting machinery. The advantages and disadvantages of using machinery to polish stone are as follows:


1. The advantages of mechanical polishing stone polishing:


Good grinding consistency, lines of different sizes can be installed in random order, with good interchangeability;


There are no waves in the polished lines, and the surface flatness and straightness are very good;


Used for polishing rotary products with good arc, high luminosity; high efficiency;


Reduce the labor intensity of grinding and polishing operations;


Improve the grinding and polishing working environment;


is suitable for assembly line production;


2. Disadvantages of mechanical polishing stone polishing:


The initial investment is relatively high, and a certain amount of equipment, work place, and forming wheel are required;


lacks certain flexibility and is only suitable for mass products;


According to different line types, corresponding forming tools should be made, and the tools are indispensable from a series of grinding wheels such as rough grinding, fine grinding, and polishing;


It is easy to break when polishing thin and long lines;


The forming wheel for grinding and polishing should be produced by a professional manufacturer, and the precision of the forming wheel is relatively high;


The polished lines have a low luminosity, and there will be traces of polishing marks on the surface of the lines that will affect the appearance of the product. The biggest shortcoming of the mechanical polishing of the lines, there is still a problem to be solved;


is not suitable for sanding fragile stone.


3. Polishing stone polishing steps and processes:


Check whether the product shape conforms to the production process and processing single shape, and then enter the grinding and polishing process after being qualified;


Before grinding and polishing, make up the glue according to the material condition, and then polish and polish after the glue is finished;


First, draw a single piece of rough grinding, leave 0.5MM fine grinding and water grinding allowance when rough grinding; Splicing: Splice the polished lines according to the installation drawing, and select and deploy according to the line surface color to ensure good color and pattern effects. After the line water mill 500# is numbered uniformly according to the requirements of the installation drawing, and then disassembled and polished, this will not cause the interface of the polished and polished line to be concave and convex;


When there is a misalignment at the interface, the transition section should be polished to extend the distance, the longer the better, and use a ruler to check the straightness when polishing;


The polished and polished lines can only be shipped after passing the quality inspection;


Special-shaped handicrafts are polished and polished to increase luminosity and reduce waves.


Choose a good polishing material;


When grinding and polishing, each abrasive or abrasive disc should be carefully checked for the polishing and polishing of the polished surface after polishing, and the traces generated by the previous abrasive should be covered after the last grinding number;


When grinding and polishing, attention should be paid to the control of water volume. Insufficient water volume can easily cause burnt surface;


Stretch as far as possible along the line element line direction during polishing, the longer the better, so as to avoid ripples;


The speed should be fast when polishing;


Using high-speed grinding and polishing electric tools;


It is best to use a forming knife for mass line grinding and polishing. This can reduce the workload of rough grinding and ensure that the lines are of good quality and shape consistency after rough grinding.
