Abstract

PURPOSE: To uniformly perform polishing work on the whole surface of a material by performing the quick replacement of an abrasive in a treating area and quick discharge of all kinds of abrasive grains of the abrasive by gravity, etc., and quickly removing them from a treating surface of the material by moving the abrasive grains at a high speed simultaneouly when high impact energy is imparted to the abrasive. CONSTITUTION: Strong vibration and vibration having high vibration frequency- small amplitude are imparted to an apparatus, and high impact energy for a movement, mixing and compression is imparted to an abrasive incorporated into this apparatus. At the same time, a used abrasive is quickly removed in an area to treat a material such as a natural and artificial lapideous material by gravity, etc., and is quickly replaced with new one, and the abrasive is supplied even to a boundary and contour undecided small area of the material, and polishing work is uniformly performed on the whole surface of the material.

Description

[Detailed description of the invention] Industrial applications The present invention relates to a method for treating natural and artificial stones.

In this specification, "natural and artificial stones, etc." (hereinafter referred to as
The term "material" is used in a broad sense to include marble, granite, other natural stones, agglomerated rocks made of the above materials and binders, concrete, plastic materials, etc.

Also, as used herein, the term "abrasive" means any kind of granules and/or powders which, when properly controlled, are capable of removing particles of the above-mentioned materials. The abrasive material forms a regularly shaped solid characterized by the necessary mechanical strength and may be interspersed or bonded on the carrier.

If the abrasives are scattered, the abrasives may be bound together with a liquid containing a binder such as hydraulic lime.

The concealed abrasive material acts on the material based on the actuation of a movable metal or ceramic instrument such as a saw blade, wire rope, disc, etc.

The abrasive material, which is connected in solid form, acts on the material to be treated based on its rotational and/or translational movement.

In either case, the device for bringing the abrasive into contact with the material is referred to herein as an "instrument."

How the abrasive works on the material Even if the abrasive component of the abrasive is minute, the abrasive component is slid along the surface of the material or sprayed onto the surface of the material based on the operation of the instrument. If the particles are removed, as is the case with granite, the particles of the material break down and become gradually separated.

Most granites are intrusive rocks of magmatic origin characterized by a crystalline structure composed primarily of varying proportions of quartz and feldspar crystals. The crystals are fixed to each other by crystallization and recrystallization under high pressure. The abrasive component penetrates the feldspar bed and "pulls out" the quartz crystals as it is slid over or sprayed onto the granite surface upon actuation of the instrument.

More generally, it is clear that the effect that an abrasive has on the material being treated is obtained both by the energy of each abrasive component and also by the number of active parts of the abrasive component that pass over the surface of the material per unit time. It is. The term "active part" means that no matter how small each abrasive component is, once the abrasive component performs its abrasive action, it tends to exhibit its effectiveness, making it more "aggressive." This is because the abrasive component has a part.

Thus, to obtain maximum efficiency, each component not only needs to be in contact with the material, but also to move around with maximum dynamic energy and to take turns as quickly as possible.

This applies to any type of abrasive material selected taking into account the material being treated.

BACKGROUND OF THE INVENTION Traditionally, abrasive materials contact materials based on regular and continuous operation of an instrument.

As a result, the following factors that determine the effectiveness of the polishing action described above are subject to several limitations.

- the energy of a single abrasive component; - the amount of the abrasive component acting on the surface to be treated; - the probability of contact between the material and the active part of the abrasive component; - the removal of the abrasive component after use and its replacement with a new component. - Removal of material caused by abrasiveness; Furthermore, conventional methods use regular and continuous movements that combine rotational and translational movements, and therefore do not require the use of expensive tools or the use of large amounts of abrasive materials. Without it, the abrasive material cannot be fully effective on uneven and complex surfaces.

Principle of the Invention The present invention is based on the principle of applying strong vibrations or high-frequency, small-amplitude vibrations to an instrument while subjecting it to conventional regular and continuous motion.

Vibration generates energy that increases the impact force of the abrasive components on the disintegrating abrasive material, which has the following effects on abrasive materials that are scattered or bonded on the instrument; Repeated local compaction in hard-to-reach areas, which provides a more thorough abrasive action over the entire surface of the material during processing; increases the speed of the moving abrasive components, thereby increasing efficiency. improve the abrasive properties of the abrasive components by continuously and forcibly alternating them to create more aggressive particles (the rnorQ aggrcss
tveparticles) reaching the material; - prompt removal of used abrasive components;
- rapid replacement with new and more potent components; - rapid removal of the abrasive from the treated surface of the material by moving the abrasive grains at high speeds; The polishing action can be concentrated in a small area.

Example 0 Sawing of Granite Currently, thin granite slabs are manufactured using two parallel metal blades fixed on a frame controlled by a crank and rocker mechanism, and a circulating grinding wheel is generally It is a metal abrasive grain bonded with limewash.

In the present invention, strong vibrations having a frequency of 6000 cycles per minute and an amplitude of 2 to 3 tenths of a millimeter are applied to the blade. The blade may be moved slowly, as in conventional methods.

0 Tenite sawn marble is usually sawn with a long saw like those used for granite, but the blade is covered with an abrasive material to eliminate circulation of the abrasive powder. In this case as well, based on the above principle, strong vibrations may be applied to the saw blade and it may be moved slowly as in the conventional method.

Engraving into surfaces such as stone is usually done by grid plasting or by instruments, which may or may not be covered with abrasive materials, by hand or by copying equipment.
attachment).

Instruments used according to the above principles must be provided with reliefs that reproduce the pattern to be engraved. The instrument is then oscillated over the surface to be carved through a thin, continuous layer of abrasive material. Depending on the usage time of the tool and the strength of vibration, engraving can be performed at different depths.

0 Use grid plasting to polish the basic surface.
Or by combustion. To improve the results, a type of plate covered with abrasive material is vibrated on the surface to be decorated through said thin and continuous layer of abrasive material. For the same purpose, a set of vibrating needles may be used instead of said plate.

Linear cuts can be made in stone by covering the surface with a layer of abrasive material and rotating the wire on an axis while vibrating it, or by moving it slowly along the axis.
