[Prior Art] [0002] In the optical industry, an optical workpiece is usually made into a circular shape, such as an infrared cutting filter of a digital camera. However, the industrial method initially cuts the formed part, which is generally square, so it is necessary to round the square workpiece to have a rounded edge to satisfy the optical application. [0003] A cylindrical grinding machine is a machine for processing workpieces of various shapes into a circular shape. The working principle is to grind a workpiece fixed by a grinding machine fixing device by a high-speed rotating grinding wheel to process it into a desired size. Round. Generally, the grinder fixing device is a pair of hollow jigs. Firstly, the air suction part of the jig is sucked by the air pump to suck the workpiece on one of the jigs, and then the other jig is brought close to fix the workpiece, and then grinded by the grinding wheel. The jig can be widely used in the rounding or rounding process of a general-shaped workpiece. However, the jig can only fix one workpiece at a time, so that only one can be ground at a time, and the productivity is too low. [0004] There has thus been a method of grinding a plurality of workpieces at a time. The method mainly utilizes a pair of jigs capable of carrying a plurality of workpieces at a time, and the workpiece is processed into a circular shape after two grindings. Please refer to the fifth figure and the sixth figure, which are conventional combination tools for spheronization, and the fixture groove is used for placing the workpiece 5 to be ground, wherein the groove 32 of the first jig 3 has two groove walls perpendicular to each other. The cross-sectional shape of the groove 42 of the second jig 4 is a semicircular shape in which the workpiece is to be rounded. First Fixture 3 and No. 094136024 Form No. A0101 Page 3 of 16 0993184889-0 1329549 Modified on May 27, 099 For each page, the two fixtures 4 are identical except for the groove shape. The spheronization process is to first put a plurality of square plate-shaped workpieces 5 into the grooves 32 of the first jig 3, and apply the UV glue, and the glue is instantaneously solidified by the irradiation of the UV lamp to adhere the plurality of workpieces 5 together. The workpiece 5 is further polished by a grinding wheel to have a semicircular portion 52 and a square portion 51, and then the workpiece 5 is placed in the semicircular groove 42 of the second jig 4 to round the square portion 51 to become a Complete circular workpiece. [0005] However, after the first round grinding process of the above process, the semicircular portion 52 of the workpiece 5 contacts the square portion 51 to generate two sharp corners 53, which are in the second shape due to their shape. During the round grinding process, it is easy to be broken by force, which causes the finished workpiece to not meet the specifications.
