High-precision machining technology, particularly surface grinding service, has become an indispensable processing method across many industries due to its outstanding dimensional accuracy, geometric precision, and superior surface quality. Through meticulous grinding techniques, components with extremely high precision and excellent surface properties can be manufactured. This technology is widely applied in aerospace, automotive manufacturing, precision instruments, and various other sectors.
High Dimensional Accuracy: Surface grinding service enables ultra-fine dimensional machining, achieving surface roughness values ranging from Ra 0.006μm to 0.1μm. It supports micro-cutting with roughness as low as Ra 0.1μm and can reach machining tolerances as precise as 0.025μm.
High Geometric Accuracy: As a generating process, surface grinding naturally corrects workpiece errors and can machine complex shapes such as internal and external cylinders, cones, planes, convex and concave surfaces, and internal and external spheres. This ensures exceptionally high shape accuracy and a certain level of positional precision.
Low Surface Roughness: Surface grinding is a micro-cutting process with shallow cutting depths and complex tool paths, effectively reducing the surface roughness of parts. This produces an ultra-smooth finish, providing an ideal base for subsequent polishing or functional coatings.
No Heat-Affected Layer: Conducted under low speed and low pressure conditions, surface grinding generates minimal cutting heat, resulting in a very thin or negligible heat-affected layer. Ground surfaces exhibit reduced friction, improved wear resistance, enhanced surface strength, and greater corrosion resistance. Additionally, the grinding process does not cause microscopic cracks.
Material Compatibility: Surface grinding service is suitable for a wide range of metals such as steel, copper, aluminum, cast iron, and cemented carbides, as well as non-metal materials including glass, ceramics, plastics, and semiconductors.
Production Flexibility: This service accommodates both one-off manual production and batch mechanical manufacturing. It does not demand highly precise equipment, enabling the processing of high-precision workpieces even on relatively simple or less precise machines under certain conditions.
The abrasives used in surface grinding are relatively simple and do not require extremely high precision. Typically, the hardness of abrasive materials is lower than that of the workpiece. Since abrasives wear down during grinding, timely dressing or replacement is necessary to maintain performance.
During surface grinding, the machine tool, abrasive, and workpiece operate in an elastically floating state, allowing automatic micro-feed. The process can be paused at any time to remove the workpiece for measurement, enabling on-the-spot adjustments to machining accuracy as needed.
