Precision Grinding Services

At Sheng Yuan, we have total 24 set of grinding machine in house, including surface grinder, center-less grinder, cylindrical ID/OD grinder, and manual surface grinder. Precision grinding can achieve tolerances as tight as ±0.0001 inches (±2.54 microns) or even tighter in some cases.

It can produce extremely smooth surfaces with roughness values as low as Ra 0.2 μm or better.

The common used material

Carbon steel, stainless steel, tool steel, high-speed steel, cemented carbide, alloy structural steel, tungsten steel, copper alloy, aluminum alloy, titanium alloy and ceramics, etc.







Big Water Grinding:

Focusing on the precision grinding processing of large plates and block parts, we provide you with processing services featuring high flatness (≤0.01mm/m²), super parallelism (±0.005mm), and excellent surface finish (Ra0.2μm or less),ensuring that the workpiece dimensions are accurate, the surface is uniform and free of defects.

Applicable to: mold base plates, mechanical table surfaces, precision instrument bases and other key components.

Slow Wire-cutting

Slow wire cutting is used for high-precision work and finishing cuts. 
It offers:

- Slower cutting speeds

- Highest level of precision and surface finish

- Ideal for parts requiring tight tolerances or superior surface quality

- Surface Roughness: Can achieve 0.4 to 1.6 μm Ra or better

- Accuracy: ±0.002 to ±0.010 mm (0.0001" to 0.0004")
