What Is Precision Machining? Precision machining is a high-precision subtractive manufacturing process that removes excess material from a workpiece to create finished parts with complex geometries and extremely tight tolerances. Dimensional tolerances are typically controlled within ±0.002 mm or even tighter, enabling the fabrication of critical components from metals, alloys, and engineering plastics that meet…
A Guide to Swiss Machining for High-Precision Parts What is Swiss Machining? Swiss machining is an advanced subtractive manufacturing method used to produce small, complex parts requiring tight tolerances. Originally developed in Switzerland for watchmaking, the process is now utilized across industries such as medical, aerospace, electronics, and automotive. This technology is among the most…

Optimization of Machining Process for Parts with Deep, Narrow Cavities Due to the structural characteristics of deep, narrow cavities, machining these parts requires tools with high length-to-diameter ratios. The process is prone to issues such as vibration and edge chipping, alongside challenges like poor cooling, difficult chip evacuation, instability, low cutting efficiency, and short tool…
Understanding CNC Machining Surface Roughness Grades and Applications In our previous article, we defined surface roughness; today, we will introduce the common surface roughness grades for metal parts and their applications. Machined surface roughness is typically measured by the average roughness (Ra) value. Manufactured parts generally range from 0.1 µm Ra to 6.3 µm Ra…
Understanding Surface Roughness Surface roughness—or simply “roughness”—refers to the characteristic of a surface not being smooth. While this is essential knowledge in the machining industry, it is often overlooked; people frequently fail to truly study or master a concept they encounter daily. Ask yourself: what does a turned surface with an Ra of 1.6 actually…
How do we control batch production with 0.0005-inch tolerances? PRS employs a three-tier precision control system, stabilizing the batch yield rate for CNC parts at over 99%. n Dongguan, Guangdong—China’s renowned “World’s Factory”—many manufacturers struggle with a common mass-production challenge: while the first article of a precision part meets all accuracy specifications, dimensions often drift…
Regarding mechanical properties after annealing and stress relief: tensile strength is 515 MPa, yield strength is 205 MPa, and elongation is 40%. Standard hardness ranges are HRB 90–100 and HRC 20–25 (Note: HRB 100 = HRC 22.9). 303 is a free-machining stainless steel containing sulfur or selenium; it is used in applications requiring excellent machinability…
