瓜生製作所 List of Products and Services

We would like to introduce the parts we manufacture with "hexagonal hole processing." We processed hexagonal holes with a width of 9mm and a depth of 4mm, along with flat knurling and cross-hole tapping, using NC automatic lathes, and performed M10 threading on a rolling machine. By processing hexagonal holes with NC automatic lathes, we can accommodate small quantities and a variety of shapes, as well as complex geometries and strict shaft tolerances that cannot be achieved through forging. 【Features】 ■ Small quantities and a variety of products ■ Capable of handling complex shapes and strict shaft tolerances that cannot be achieved through forging *For more details, please refer to the external link page or feel free to contact us.

We would like to introduce our product, the "Cell Spacer." It provides excellent anti-slip properties for beautifully processing knurled peaks. There are various types available with different outer diameters and tap sizes, and by processing 24 hours a day, we can reduce costs. 【Features】 ■ Excellent anti-slip properties ■ Various types available with different outer diameters and tap sizes ■ Cost reduction through 24-hour processing *For more details, please refer to the external link page or feel free to contact us.

Our company specializes in "screw machining." To reduce processing costs, depending on the quantity of machining and the length of the screws, we may either perform all machining on an NC lathe or conduct secondary processing on a rolling machine. In the case of the NC lathe, it can accommodate a wide range of screw sizes, but it cannot handle longer screws. The rolling machine can handle sizes from M3 to M10 (for those with a nut). It can also process relatively long screws. 【Features】 ■ The NC lathe can accommodate a wide range of screw sizes. ■ The rolling machine can handle sizes from M3 to M10 for those with a nut. *For more details, please refer to the external link page or feel free to contact us.

We would like to introduce our "Insert Nuts (Knurled Machined Parts)." The tapping can be done up to a maximum of M8, depending on the type of material. If machining is done using a threading tool, it is possible to go beyond that. Knurling can achieve flat, diamond, and angled patterns by utilizing both cutting and rolling processes. In some cases, knurled materials may be used depending on the part. 【Features】 ■ Tapping can be done up to a maximum of M8, depending on the type of material. ■ If machining is done using a threading tool, it is possible to exceed M8. ■ Knurling can achieve flat, diamond, and angled patterns by utilizing both cutting and rolling processes. *For more details, please refer to the external link page or feel free to contact us.

We would like to introduce our main product, the "Small Diameter Precision Shaft," from Uryu Manufacturing Co., Ltd. Our company is a factory engaged in precision cutting processing of mass-produced parts using NC automatic lathes. There are many components that undergo various complex processes such as threading, knurling, slitting, milling, and tapping (front, back, cross) on the shafts. *For more details, please refer to the external link page or feel free to contact us.

Our company performs prototype machining, complex machining, and mass production machining using NC automatic lathes. The processing lot starts from 100 pieces for prototypes and from 1,000 pieces for mass-produced items. (Currently, there are products being processed at a monthly rate of about 70,000 to 80,000 pieces using multiple machines.) Basically, we focus mainly on mass production machining, so we accept orders for prototypes that will lead to mass production. *For more details, please download the PDF or contact us.
