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. ![]() ![]() Centerless Grinding Outer-inner Cylindrical Grinding With a high-speed and highly stable process, an ultra-precision Achieve ultra-high precision of ±0.005mm for the tolerance of ±0.002mm for the outer diameter is achieved. inner circle and ±0.002mm for the outer diameter. Surface Roughness: Ra≤0.4μm. The surface finish reaches Ra0.2μm,ensuring perfect It is suitable for the processing of a large number of precision fit and long-term durability of the parts. parts such as shafts, pipe fittings and bearings. It is applicable to key components such as hydraulic valve cores,precision shaft sleeves, and high-precision molds. 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") ![]() ![]() ![]() ![]() EDM ![]() ![]() ![]() At Sheng Yuan precision machining factory, we have 4 set of Sinker EDM machine in house, with 25 years experiences in precision machining industry, combine cnc machining process, and precision grinding process, we can provide you one-stop machining solution for your precision engineering requirements.
