Sanluo Precision's processing plant strictly controls the quality of eccentric turning CNC: clamping correction uses dial gauge to measure radial runout <0.01mm and axial runout <0.02mm to ensure clamping accuracy; eccentric detection uses two center pins measurement, micrometer to measure eccentricity with accuracy ±0.01mm, V-block to measure maximum and minimum diameters of eccentric shaft to calculate eccentricity, coordinate measuring machine to measure coordinates of two centers to calculate eccentricity and eccentric angle with accuracy ±0.003mm; dynamic balance eccentric parts have large centrifugal force during rotation and require dynamic balance with balance accuracy G6.3-G16 grade to reduce vibration; surface roughness Ra0.8-3.2μm with no chatter marks or tool marks, smooth surface; hardness detection after heat treatment with hardness HRC25-55, uniform hardness and normal structure.
