Grinding Services

Grinding is the core final process in precision manufacturing that determines the final dimensional accuracy, geometric accuracy and surface quality of parts. Xinling Machinery Manufacturing provides professional surface grinding and cylindrical grinding services, specially designed to meet the stringent requirements of the industry for part flatness, roundness and surface finish.We deliver stable, high-quality grinding solutions for a wide range of precision machining needs.

How CNC Grinding Works?

How CNC Grinding Works?

CNC grinding uses a high-speed rotating precision grinding wheel to perform micro-cutting on the surface of metal workpieces.The CNC system accurately controls the position, feed rate and movement path of the grinding wheel and workpiece, removing excess material to achieve extremely high dimensional accuracy, form accuracy and mirror-like surface finish.It is usually used as the final finishing process for precision parts, ensuring products meet strict tolerance and surface quality requirements.

Advantages of Grinding Services

Ultra-high Flatness & Parallelism: Parallelism accuracy up to 0.01/300mm, ensuring consistent precision for mass-produced parts.

Mirror-like Surface Quality: Surface roughness as low as Ra ≤ 0.2μm, reducing friction and improving wear resistance and sealing performance.

Deformation Control for Thin-Wall Parts: Flexible clamping technology ensures perfect machining of easily deformable thin-wall workpieces.

Micron-level Geometric Accuracy: Roundness accuracy reaches 0.003mm, ensuring stable operation and high concentricity of shaft components.

Precise Dimensional Control: Tolerance can be controlled within 0.002–0.005mm, supporting multi-scenario grinding including outer/inner diameter and inner taper.

Applications of Grinding Services

Mold Manufacturing: Precision finishing of mold cavities, cores, parting surfaces and guide holes to improve part accuracy and extend mold service life.

Precision Component Machining: Serving aerospace, automotive and electronics industries by machining shafts and hydraulic valve bodies to ensure stable equipment operation.

Special Materials Machining: Specialized in high-hardness and brittle materials such as cemented carbide, ceramics and hardened steel, solving challenges of traditional machining processes.

High-Cleanliness Machining: Suitable for optical instrument bases and semiconductor connectors, achieving mirror finish below Ra 0.2μm to meet the strict requirements of optoelectronic products.
