The part is a ‌four-claw nut‌ (also known as claw nut or claw bolt), which is a fastener with multiple claw structures. It is commonly used for connecting and fixing in scenarios such as furniture, speakers, and wooden board inlay. Its non-standard attributes are reflected in the following aspects:

Customized structure‌: The number, shape of claws, and inner hole dimensions can be adjusted according to requirements (for example, the curvature of claws and the precision of inner holes in the two parts in the picture may differ).

Flexible dimensions‌: Common specifications include M4×14×7 (thread specification M4, length 14mm, claw diameter 7mm), but non-standard parts can support a wider range of dimension customization (such as thread specifications, claw length, and material hardness).

Suitability of Swiss-type Lathe Processing

Swiss-type lathes (Swiss-type lathe) are good at processing slender, high-precision parts, which is highly compatible with the processing requirements of four-claw nuts:

Precision guarantee‌: It can achieve high-precision processing of inner holes, outer circles, and claws (such as tolerance ±0.01mm), meeting the assembly requirements of fasteners.

Efficiency advantage‌: It integrates multi-axis processing functions, which can complete turning, drilling, tapping, and other processes at one time, suitable for small and medium batch non-standard parts production.

Material compatibility‌: It supports processing of metal (such as carbon steel, stainless steel) or plastic materials. The metallic luster of the parts in the picture shows that they may be made of steel or aluminum alloy, which is within the processing range of Swiss-type lathes.

Processing Suggestions and Precautions

Clearly define customization requirements‌: Provide detailed drawings (such as the number of claws, inner hole depth, surface treatment requirements) to avoid processing deviations caused by ambiguous structures.

Material and hardness selection‌: For ordinary scenarios, 4.8 grade carbon steel (such as Q235) can be selected; for high-strength requirements, it can be upgraded to 8.8 grade alloy steel (such as 45# steel). After processing by Swiss-type lathes, heat treatment can be combined to improve hardness.

Batch and quotation communication‌: The processing cost of Swiss-type lathes is related to the batch. Small batches (10000-50000 pieces) are suitable for trial production, and large batches (50000 pieces or more) can negotiate to reduce the unit cost. It is recommended to contact the manufacturer to provide specific drawings to obtain accurate quotations.
