In precision instruments such as handheld computers, a large number of glass plate parts are used as display windows and LCD panels. At the time of assembly, these glass plate parts are placed in a narrow space intricately together with precision parts such as a printed wiring board. In the case of an LCD panel or the like, a glass panel and a flexible PCB are supplied as an integrated component.

線板や精密部品が接触して損傷する怖れがある。[0003] Usually, fine cuts are present in the cut edge of the glass plate immediately after cutting, and there are many irregularities due to cracks and chips. If a glass plate immediately after cutting is used as a glass plate component of a precision instrument, there is a fear that the printed wiring board or the precision component may be damaged by contact with sharp edges or sharp irregularities at the ends.

おくことが好ましい。[0004] These corners and irregularities may cause the guide rolls and carriers of the equipment used in the assembling process to be shaved, and the shavings may be taken into the product, which is also undesirable in terms of work safety. Furthermore, if cracks are present in the cut, the strength of the glass sheet component will be significantly reduced. Therefore, it is preferable to finish the end of the glass plate part without any corners, irregularities and cracks.

粒を金属結合剤で固めた研磨ホイールをいう。Heretofore, in order to remove corners, irregularities and cracks from the edge of a glass plate, the corner of the edge of the glass plate has been polished and chamfered using a diamond wheel. The diamond wheel generally refers to a polishing wheel obtained by hardening diamond abrasive grains with a metal binder.

Grinding with a rigid or inelastic material such as a diamond wheel results in "tear type" or "crack type" cutting, and many new cracks and pits are formed on the polished surface As a result, the unevenness cannot be effectively removed from the end of the glass plate. Further, in the case of a thin glass plate, it may be damaged by cracks generated during polishing.

That is, in this method, a polishing end position is determined on a glass plate in accordance with a desired cutting allowance, and the diamond wheel is advanced to that position.

Further, even when this position adjustment is performed by computer control (NC device), 60 times is required for inputting position data.
It takes a long time of up to 120 minutes, and it is difficult to efficiently perform the chamfering operation.

切削態様が「剪断型（shear type）」となり易い。The chamfering of the edge of the glass sheet according to the method of the present invention is performed by polishing the corner of the edge of the glass sheet by a predetermined polishing amount using a resin-bonded polishing wheel. The resin-bonded polishing wheel is a polishing wheel in which abrasive grains are solidified with a resin binder. Unlike a diamond wheel, a resin-bonded polishing wheel has flexibility and elasticity. Therefore, when polishing a brittle material, it exhibits toughness and followability on the surface to be polished,
The cutting mode is likely to be "shear type".

The surface to be polished formed by the shearing type cutting mode is referred to as a “shear section”. The shear surface is a smooth cut, and its appearance looks brilliant.

It is preferable to manufacture according to the method described on page 4, upper right column, line 2 to page 6, lower left column, line 16 of 94336.

定の時間押し当てることにより行う。FIG. 1 is a perspective view schematically showing a state in which the edge of a glass plate is being polished by the method of the present invention. Polishing of the end portion of the glass plate is generally performed by fixing the glass plate 101 such that the width direction of the polished end portion thereof coincides with the axial direction of the polishing wheel 102, and moving the resin-bonded polishing wheel 102 while rotating the same. This is performed by pressing the outer peripheral surface against the corner 103 at the end of the glass plate for a predetermined time.

せる時間又は研磨ホイールの回転速度を変化させること
によっても制御することができる。The load for pressing the polishing wheel against the corner of the glass plate is changed according to the desired amount of shaving and the amount of polishing. That is, since the resin-bonded grinding wheel has flexibility and elasticity, the load pressing the grinding wheel can have a certain width. This load correlates with the polishing amount per unit time, and the polishing amount can be controlled by this load. The amount of polishing can also be controlled by changing the time during which the polishing wheel is brought into contact with the glass plate or the rotation speed of the polishing wheel.

小さいと研磨が不十分となるからである。Incidentally, in the diamond wheel conventionally used for chamfering the edge of the glass plate, the load for pressing the polishing wheel must always maintain an optimum value.
The load cannot have a certain width. This is because the diamond wheel is rigid and inelastic, so that if the load is slightly larger than the optimum value, the glass plate will be damaged, and if the load is smaller than the optimum value, the polishing will be insufficient.
