Service Overview
Surface grinding is a machining process used for precision grinding of flat surfaces of workpieces. It utilizes a high-speed rotating grinding wheel to grind the workpiece surface, removing material, correcting flatness, and reducing surface roughness, thereby achieving precise dimensional accuracy and excellent surface quality. Surface grinding is widely used in mechanical manufacturing, mold processing, electronics, and other industries, and is an important processing method for ensuring the flatness and surface quality of parts.

Application areas
Mechanical Industry
Processing flat surfaces of various mechanical parts, such as machine tool guide rails, flat plates, sliders, and gear end faces, to ensure the flatness and dimensional accuracy of the parts, and improve the assembly accuracy and performance of mechanical products. For example, in the case of precision grinding of machine tool guide rails, a straightness of 0.01 mm/m and a surface roughness of Ra 0.4 μm were achieved.
Mold Manufacturing Industry
Grinding the parting surfaces, mounting surfaces, and template planes of molds is a critical machining process in mold manufacturing. It ensures the accuracy and surface quality of the mold, thereby improving its lifespan and the quality of the molded products.
Electronics Industry
We process the flat surfaces of metal substrates, heat sinks, shielding covers, and other components used in electronic equipment, meeting the precision and surface quality requirements of the electronics industry and ensuring the performance and reliability of electronic devices.
Automotive Industry
Grinding the flat surfaces of critical parts such as engine cylinder blocks and transmission housings improves the machining accuracy and assembly quality of automotive components, enhancing the power performance and reliability of automobiles. For example, precision grinding of the upper surface of the engine cylinder block provides a high-precision reference plane for engine assembly.
Frequently Asked Questions
What are the advantages of surface grinding compared to other surface machining methods?
Surface grinding machines offer high processing accuracy, with superior flatness and dimensional accuracy compared to general milling and planing methods; they also produce excellent surface quality with low roughness and can process high-hardness materials. Milling and planing methods, on the other hand, have relatively limited accuracy and surface quality, and are less effective in processing hard and brittle materials.
What is the minimum surface roughness that can be achieved with a surface grinding machine?
Under conventional machining conditions, the surface roughness achieved by surface grinding machines can reach Ra 0.2 – Ra 1.6 μm. By selecting finer-grained grinding wheels, optimizing grinding parameters, and performing appropriate finishing processes, the surface roughness can be further reduced to meet higher surface quality requirements.
What are the requirements for workpiece clamping when using a surface grinding machine?
Workpieces must be securely and evenly clamped to prevent displacement and deformation during grinding. Common clamping methods include electromagnetic chuck clamping and vise clamping. For irregularly shaped or large workpieces, special fixtures may be required. During clamping, attention should be paid to alignment to ensure that the workpiece’s processing surface is parallel to the worktable surface, thereby guaranteeing processing accuracy.
What special materials can be processed using surface grinding machines?
Surface grinding machines can process a variety of special materials, such as hard and brittle materials like cemented carbide, ceramics, and quartz, as well as high-hardness steels that have undergone heat treatment. For these special materials, appropriate grinding wheels and grinding process parameters must be selected to ensure smooth processing and high-quality results.
