Abstract

PURPOSE:To obtain means of grinding glass plates through fluid pressure varied at the R section or the like by constructing machining wheels and machining spindles provided with said wheels so as to be pressed against said glass plates by means of fluid floats. CONSTITUTION:Grinding equipment 1 allows glass plates 2 to make one linear motion (Y-axis motion), and machining heads 3 to make the other linear motion (X-axis motion) perpendicularly intersecting the Y-axis motion. While the machining wheels 4 are moved around the periphery of the glass plates 2, the heads 3 make swing motion (swing-axis motion) around the axes perpendicular to the glass-plate surfaces, allowing the wheels 4 to grind the peripheral surfaces of the glasses 2 while maintaining a definite angle against them. And, in this state, the spindles 19 subsequently thereto, the wheels 4 are pressed against the glass plates 2 due to the fluid actuators 22 of the heads 3, constituting fluid float mechanism. Thus, grinding is carried out while varying the fluid pressure at the R sections.

Description

[Detailed description of the invention] The present invention includes IJ, automobile crows, and other irregularly shaped blackcurrant tongues, corner radiuses, and various shapes with right angle corners.

Place the glass 11x in a water tank and move the periphery of the glass 11x while keeping the machining wheel at a constant angle η with respect to the outer circumferential surface of the glass plate using numerical control.
Reduction (Regarding improvement of 1 machine.

In addition, while keeping the small wheel at a constant angle of -C to the outer circumferential surface of the glass plate, move the periphery of the glass plate. Bando Kiko Co., Ltd. was the first company in the world to develop the LFI machine, which is used in the United States, Japan, and Japan.

The present invention provides a numerically controlled grinding machine J:
This invention is a great improvement.

By the way, even though it is a numerically controlled grinding machine like this,
At present, 42 machines are used for automobile glass (swing movement).A two-head is installed at the end of the machine, and a wheel pushes the horizontally rotating glass plate. ” (Pull C611 Sharpening Iso Qi) T” Yes, the cannibal wheel and the cantilever wheel are fixedly supported.

Now, automatic middle glass etc. have a complicated 4J shape and are 43mm.
In particular, the corners and corners have a steep, small rounded shape that protrudes for a long time. In order to sharpen it, it is necessary to reduce the sliding speed very much and make the IJII wheel follow the radius.

However,) Thrisbee-1・J17! Drop to i', N'
i'''1111'lt',f'1 Follow the curve along the radius.The curve may become misshapen, or it may not be within the stipulation 1.

This is the result of reducing the feed width by 1. IJ and fill cutting by 11. The period between +1 and 1 is longer, and the amount of over-grinding is reduced by 1 in this part. In other words, since the feed speed is ), the distance 84 in contact with the processing wheel around the middle length of the glass plate becomes longer, and the grinding depth increases by 1'. Of course, when I increased the follow-up speed of the Kato hole at the corner radius above, the tf was fixed to fjJ radius.
Accurate tracking becomes impossible, and 111. .

In addition, @tsutsu said that the difference between the cutting speed of the automobile force lath, etc. before starting the grinding process is the current usage (Jλ・1 shikku, -1

Therefore, the present invention aims to provide an ωI grinding method and a grinding machine that eliminate the above-mentioned defects.
