◇What is a D-cut part? D-cut is a machining technique that flattens a portion of a cylinder to create a D-shaped cross-section. It is commonly used for parts with rotation prevention or space constraints and is widely utilized in precision instruments and automotive components. ◇Product Details - Material: C3604 (Free-cutting brass) - Dimensions: φ12×17.5mm - Machining Tolerance: ±0.01mm - Surface Finish: Turned finish ◇Features - Stable dimensional tolerance due to high-precision machining - Smooth turned finish for good surface quality - High reliability for precision instruments ◇Machining Method A CNC multi-tasking lathe was used to machine the D-cut shape from C3604 brass material. To ensure the shape accuracy of the D-cut section, optimal machining conditions were set while considering cutting speed and tool wear. Additionally, in the finishing process, fine surface roughness was managed to achieve a high-quality turned finish. ◇Initiatives In the machining of this product, a multi-tasking CNC lathe was utilized to improve efficiency through process consolidation. Inspections were thoroughly conducted under strict dimensional control to ensure quality. Furthermore, by leveraging the characteristics of C3604 material, optimal tools were selected while minimizing cutting resistance.

By processing the head of the screw into a flat knurling shape with continuously formed parallel grooves, it not only provides a non-slip effect but also serves a decorative purpose for the appearance. Flat knurling is widely used on parts that are gripped and turned, such as the heads of screws and the crowns of wristwatches, as well as on contact surfaces of mechanical components. Metal materials are often used for processing. If you have concerns about knurling processing, please feel free to consult Hozawa Manufacturing. We welcome inquiries for small lot processing and prototypes.

◇What is an M0.8 screw? It is an ultra-small screw with a diameter of just 0.8mm. It is an essential component for securely fastening parts together in communication devices and medical equipment. Due to its size, both processing and assembly are very delicate. Even a slight burr or deviation in precision can be critical, so reliable technology is necessary. ◇Features - Burr-free finish provides assurance of quality - High precision even in the extremely small M0.8 size - Capable of handling small production runs - Numerous achievements in communication devices and medical equipment - Stable quality born from craftsmanship and the latest equipment ◇Processing Method We meticulously check tool adjustments and temperature management. Especially at this tiny size, vibrations during processing can be critical, so we are thoroughly committed to adjusting processing conditions. Furthermore, each piece is inspected after completion. Although small, we guarantee "top-quality." If you have concerns like, "How can I make such a small part?" please feel free to consult us. Especially for fine parts used in communication devices and medical equipment, our technology can be of assistance. Let's solve your problems with burr-free, high-precision processing!

An insert nut is a type of nut used to enhance the bonding of synthetic resin during the molding process with molds and other equipment. By inserting it into synthetic resin through methods such as press-fitting, it strengthens the bond between materials. Additionally, the shaft of the insert nut is often subjected to knurling. This surface treatment creates fine irregularities that serve to prevent disengagement, rotation, and provide friction and grip at the joint. This product features slits processed into the knurled outer circumference. It is also used in various products such as housings and structural components of machinery made from materials like plastic. If you have any issues with insert nuts, please consult Hibisawa Seisakusho. Feel free to inquire about prototypes and mass-produced items.

By applying a flat knurling process that continuously forms parallel grooves on the surface of the material, a non-slip effect is achieved. Flat knurling is widely used on parts that are gripped and turned, such as the heads of screws and the crowns of wristwatches, as well as on contact surfaces of mechanical components. Metal materials are often used for the processing. If you have any concerns about knurling, please feel free to consult Tobizawa Manufacturing. We welcome inquiries for small lot processing and prototypes.

◇What is knurling? Knurling is a process that creates fine unevenness on the surface, which enhances the bonding of materials by inserting them into synthetic resin through methods such as press-fitting. It serves to prevent parts from coming apart, to stop rotation, to provide friction and grip, and to act as a slip-resistant feature. Mass production processing from knurled materials We can accommodate both cases of knurling processing on lathe machines. If you have concerns about knurling, please feel free to consult with Tobisawa Manufacturing. We also welcome inquiries for small lot processing and prototypes.
