Description

Glass cutting machine {A machine for cutting and grinding of a glass}

The present invention relates to a glass cutting machine that can perform various glass cutting processes as a single work tool, and more particularly, to cut or chamfer the glass to a certain size or to smoothly finish the perforations and rough cut surfaces of a specific part. The present invention relates to a glass cutting machine that can reduce work space and increase work efficiency by easily replacing various cutting tips with a corresponding cutting tip on a shanghai-dong and rotating drive shaft.

In general, glass is hard and transparent, and is widely used for items requiring external perspective such as windows or cabinets. Especially, in case of flat glass, a hole of a corresponding size is used by using a pistol-type drill, an angle grinder, and a glass knife. It can be punched or gently chamfered, chamfered or cut to the desired size.

FIG. 8 illustrates a cutting operation for chamfering the center portion of the edge of the plate glass 110 using a conventional drill 120 and a glass knife 130, and as shown in the drawing, of the plate glass 110 to be chamfered. In order to remove the center portion of the edge in the shape of a hole, first, A and B portions of the plate glass 110 are drilled with a pistol-type power drill 120 equipped with a cutting tip 132 on the drill chuck 122, and a glass knife 130 Draw a cutting surface on the plate glass 110 in the cutting order of C → A, A → B, B → D and remove the corresponding part, and then attach a grinding tip (not shown) to the drill drill 120 again. The chamfered cutting operation of the plate glass 110 was carried out by uniformly polishing the inner side of the cut surface of 110.

9 illustrates a drilling operation for drilling holes in the plate glass 110 with the electric drill 120 mounted on the conventional drill stand 121. As shown in the drawing, holes of a predetermined size in the plate glass 110 are precisely shown. In order to drill, the drill chuck 122 with the drill tip 133 mounted on the drill stand 121 is mounted on the plate glass 110, and then the operating lever 123 of the drill stand 121. Pulling through the drilling tip 133 of the electric drill 120 through the drilling guide hole 124 of the drill stand 121 to penetrate the hole of the desired size in the plate glass 110 by making the drilling operation of the plate glass 110 lost.

10 and 11 illustrate the chamfering operation of smoothly finishing the edges of the plate glass 110 using the conventional chamfering machine 140 and the angle grinder 145, the rotation of the drive motor 141 Polishing the plate glass 110 against the polishing wheel 142 of the chamfering machine 140 which is rotated by power, or the edge of the plate glass 110 by the rotating polishing wheel 146 of the angle grinder 145. Was processed smoothly.

As such, in order to chamfer by cutting the plate glass 110 to a certain size or to chamfer holes and specific portions of a desired size, the pistol-type power drill 120 or the angle grinder 145 and the glass according to the corresponding work up to now. There are many work tools, such as knife 130 and chamfering machine 140, to prepare and process them individually, so that the work tools increase more than necessary, which makes it difficult to prepare work tools. In order to have a work tool, at least 3-4 pyeong of work space is required, so that the work space increases more than necessary and the work efficiency is inevitably deteriorated.

Accordingly, the present invention has been made to solve the various inconveniences of the conventional cutting and punching and chamfering of the glass as a plurality of working tools, and cut or chamfer the glass to a certain size or smoothly finish the perforation and rough cut surface of a specific part It is an object of the present invention to provide a glass cutting machine that can be conveniently processed by exchanging and mounting only the corresponding processing tip for various glass cutting processing such as processing.
