Generally, a laser cutting machine is widely used as a means for cutting a workpiece such as a metal plate into a desired shape, and the workpiece is usually cut in a state of being placed on a flat work surface called a grid.

FIG. 1 shows a conventional workbench 1000 for a laser cutter. The workbench 1000 is formed in a structure in which a plurality of narrow and long unitary grids 100 in a blade form are arranged in parallel on a work support 200, (100) has a structure in which a concave-convex portion having an upwardly protruding portion is repeatedly formed so that an upper surface thereof can make point contact with a bottom surface of the object to be processed.

However, in the conventional workbench 1000 for laser cutting, when a cutting operation of an object to be processed is performed, a foreign matter, that is, a dross S that is melted and separated from the object is fused to the tip portion of the unit grid 100, The accuracy of the cutting operation is lowered because the degree of flatness of the object supported on the upper part is influenced by the droplets S accumulated in the unit grid 100. [

For this reason, in order to maintain the flatness of the work table 1000 for a laser cutter, it is necessary to separate the unit grid 100 from the work support table 200 and to replace the unit grid 100, which affects the flatness of the work table, So that the working time is somewhat long and the cutting operation efficiency of the object to be processed is lowered.

In addition, in the laser cutting process, there is a problem that the laser beam passing through the object to be processed is reflected to the bottom surface of the object to be processed through the unit grid 100 to damage the object.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned problems, and it is an object of the present invention to provide a laser cutting method and a laser cutting method, in which when a flatness of a support plate for supporting an object to be processed is lowered due to a dross generated by melting an object, And a structure for allowing a part of the support plate to be replaced more quickly.

According to an aspect of the present invention, there is provided a plasma processing apparatus including a plate portion having at least one insertion hole formed at an upper side thereof, and a support pin inserted into the insertion hole at a lower end portion, A first plate having a first groove formed on one side of an upper portion thereof and a second plate having a second groove formed on an upper side thereof corresponding to the first groove and the first groove and the second groove, There is provided an object to be processed for a laser cutter, wherein the insert hole is formed while being opposed to the object to be processed.

In addition, it is preferable that the plate portion has a draw-out hole formed on one side of the plate corresponding to the lower end of the support pin when the support pin is inserted into the insertion hole.

Further, it is more preferable that at least two fixing holes are formed on one side of the plate portion.

The first plate and the second plate may include a plate body and at least one support protrusion formed on one side of the plate body and having a groove formed on one side of the plate body, It is more preferable that the support protrusions of the second plate have the first groove portion and the second groove portion formed on one side of the upper side facing each other.

In addition, it is preferable that the support pin has a rounded top.

According to the present invention, when the flatness of the object to be machined is reduced by fusing the dross to the support plate, the support pins to which the dross is fused can be easily replaced, The working efficiency is improved.

In addition, since the bottom surface of the object to be processed is sufficiently spaced from the upper portion of the support plate due to the space formed between the support pins and the support protrusions, the laser beam passing through the object during laser cutting is reflected It is possible to prevent the object to be processed from being damaged.
