[0001] The present invention relates to a spheronization apparatus and a spheronization method using the spheronization apparatus. [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 grinds a plurality of square workpieces into a columnar body, and then grinds the columnar body into a cylinder by a grinding step, and the cylinder is decomposed into a desired circular workpiece. Referring to the first figure, the grinding step can be divided into a front semi-circular grinding step and a rear semi-circular grinding step. The front semi-circle grinding step is specifically: providing a grinding wheel 8 with a semicircular concave 095102373 on the rim. Form No. A0101 Page 3 / 21 pages 1003182266-0 1345508 __ 100 years of May 20th Shuttle replacement page The groove 81 has a cross section in the radial direction of the grinding wheel 8 as shown in the second figure; the columnar body 7 is fixed, and the columnar body 7 is ground by the grinding wheel 8 to have a semicircular portion 71 and a square portion 72. The rear semi-circle grinding step is: the columnar body 7 formed by the first semi-circle grinding step is reversed and fixed, and the unpolished square portion 72 faces the grinding wheel 8, and the unpolished square portion 72 is ground by the grinding wheel 8 into The semicircle makes the columnar body 7 a complete circular workpiece. [0005] However, after the previous semi-circle grinding step of the above process, due to the shape limitation of the grinding wheel 8, the semi-circular portion 71 of the columnar body 7 and the square portion 72 contact each other to generate two sharp corners 73, the tip Due to its shape, the corner 73 is easily broken by force during the post-circular grinding process, resulting in the finished product not meeting the specifications, resulting in a lower yield of the finished product. SUMMARY OF THE INVENTION [0007] In view of the above circumstances, it is necessary to provide a spheronization apparatus that can improve the yield of a workpiece. In addition, it is necessary to provide a spheronization method that can improve the yield of the finished product of the workpiece. A spheronization device for spheronizing a workpiece, comprising: a first jig, a second jig, a first grinding wheel and a second grinding wheel; the first jig is provided with a first accommodating device a second receiving groove is disposed on the second jig; the first grinding wheel includes a wheel body having an annular groove on the rim of the wheel body having a semicircular groove wall along a circumferential direction thereof.
