Precision machining of φ12×17.5mm C3604 brass D-cut parts.

D-cut parts processing using brass material.

◇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.
