External cylindrical turning applications: Shafts and cylindrical components. Technical parameters: Rough turning: Cutting depth 2-5mm, feed rate 0.2-0.5mm/rev, spindle speed 300-800 rpm. Finishing turning: Cutting depth 0.1-0.3mm, Feed rate 0.05-0.15mm/rev, Spindle speed 1000-2000 rpm. Case Study: When machining K414 ultra-hard material shafts, employ the parameter combination of S360 spindle speed, F0.1 feed rate, and 0.2mm cutting depth to minimize tool wear. Boring Applications: Bearing bores, hydraulic cylinder machining. Technical Parameters:

Nuts are indispensable standard components in mechanical connections, achieving fastening functions through cooperation with bolts. Their manufacturing centers on lathe turning as the core process, combined with thread forming technology to ensure precision and strength. The following details are provided across four dimensions: manufacturing processes, quality control, application scenarios, and development trends: I. Core Lathe Machining Processes for Nuts 1. Blank Preparation Material Selection: - Carbon steel (Q235, 45#): Low cost, suitable for general mechanical connections. - Stainless steel (304, 316): Corrosion-resistant, used in food and chemical industries. - Copper alloy (H62): Excellent conductivity, used for electrical connections. - Alloy steel (40Cr): High strength, used for high-load applications.

Precision parts manufacturing involves numerous considerations in mechanical engineering. Even the smallest components feature extensive classifications and significant functionality—though diminutive in size, their impact is substantial. In modern society, mechanical equipment is indispensable for product manufacturing. Machinery comes in diverse types, typically composed of parts and components, with different equipment configurations requiring distinct assemblies. To enhance a part's performance characteristics, machining is often essential. The precision machining process involves numerous critical considerations. Operators must strictly adhere to procedures to prevent errors during processing, from
