Problems solved by technology

[0005] However, after the first semicircle grinding step described in the above process, due to the shape limitation of the grinding wheel 8, two sharp corners 73 will be produced at the position where the semicircular part 71 of the columnar body 7 contacts with the square part 72, and the sharp corners 73 are due to The reason for its shape is that it is easy to be broken under force during the semicircular grinding process, resulting in the finished workpiece not meeting the specifications, resulting in a low yield rate of the finished workpiece

Abstract

An abrasive wheel for rounding a workpiece has a wheel body with a slot ring on its wheel rim. Said slot has a semi-circular wall and two oblique side walls extended outward. A rounding apparatus using said abrasive wheel and its rounding method are also disclosed.

Description

【Technical field】 [0001] The invention relates to a grinding wheel, a rounding device and a rounding method using the grinding wheel. 【Background technique】 [0002] In the optical industry, the optical workpiece is usually made into a circle, such as an infrared cut filter (Infrared cutting filter) of a digital camera and the like. However, the initial cutting shape of the industrial method is generally square, so it is necessary to round the square workpiece to make it have rounded edges to meet optical applications. [0003] Cylindrical grinder is a machine used to process workpieces of various shapes into a circle. Its working principle is to use a high-speed rotating grinding wheel to grind the workpiece fixed by the grinding machine fixture to process it into a circle of the required size. shape. The general grinding machine fixture is a pair of hollow fixtures. Firstly, the air pump is used to inhale the hollow part of the fixture to absorb the workpiece on one of t...
