Surface Grinding Machine: Guaranteeing ultimate flatness and smoothness
Our surface grinding machines specialize in creating and grinding high-precision flat surfaces, stepped surfaces, and side surfaces on a variety of workpieces.
Core Technological Advantages
Ultra-high flatness and parallelism: We can consistently guarantee excellent flatness and parallelism; for example, parallelism accuracy can reach 0.01/300mm, ensuring consistency in high-volume production of parts.
Exceptional surface finish: Achievable surface roughness is as low as Ra 0.8μm, or even better, providing a near-mirror finish for parts, reducing friction, and improving wear resistance and sealing performance.
Specialization in thin-part machining: For easily deformed thin workpieces, we utilize special tooling processes such as elastic pads to effectively control machining deformation and achieve perfectly flat surfaces.
