Custom Precision Stainless Steel Turning Parts Polishing Threaded Holes

Made of high-quality stainless steel, after multiple machining processes such as turning, it can be used in various scenarios. Polishing not only increases industrial performance but also improves aesthetics.

Material: SS304

Basic Size:OD25mm, ID22mm, L:78mm,

Net Weight: 0.063 KGS

Cylindricity： 0.05mm

Tolerance of ID 22: +/- 0.02mm

Roughness: Ra1.6

What is the best process to achieve the tolerance +/-0.02 for the inner diameter of 22mm?

For ±0.02mm tolerance on a 22mm inner diameter, a combination of CNC machining (for roughing) followed by honing (for finishing) is typically the best approach. Proper tooling, quality control, and environmental factors are also crucial to achieving this level of precision.

1. Primary Process: CNC Machining

1.1. CNC Turning or Milling: Use high-precision CNC machines to achieve a rough-to-finish cut. Advanced CNC lathes with modern tooling are capable of holding tight tolerances consistently.

1.2.Tooling: Ensure high-quality carbide or diamond-coated tools to maintain dimensional accuracy and reduce tool wear.

2. Secondary Process: Precision Grinding or Honing

If the CNC machining process does not achieve the desired tolerance:

2.1. Grinding: Internal cylindrical grinding is ideal for achieving precise tolerances and surface finishes.

2.2. Honing: A honing process is highly recommended for inner diameters, as it provides excellent control over tight tolerances, roundness, and surface smoothness.

3. Inspection and Quality Control

Use high-accuracy bore gauges, air gauges, or CMM (Coordinate Measuring Machine) for precise measurements.

Perform in-process inspection to ensure parts meet tolerance before moving to subsequent operations.
