Grinding micrometer thread pitch accuracy
• Adjacent pitch error: 0.0015mm
• Roundness of middle diameter: 0.002mm
• Pinch diameter cylindricity: 0.003
• Thread surface roughness: Ra0.4
• Half angle accuracy of tooth profile section: 30 ° ± 15'

• The main components of the machine bed are installed on the cast iron bed, and the main operating mechanism is installed in front of the bed;
• The worktable moves longitudinally along the front bed sliding guide rail, and the grinding wheel frame moves horizontally along the rear bed sliding guide rail; its movement is stable and accurate, light and flexible;
• The grinding wheel spindle is mounted on the grinding wheel frame. The grinding wheel spindle adopts a high-precision sliding bearing structure. The spindle speed is adjusted by AC frequency conversion method, which can be selected in the range of 2700~3000 r/min;
• The rear of the grinding wheel frame is equipped with an automatic grinding wheel dresser, which can realize the automatic feeding and dressing of the grinding wheel dresser. The grinding wheel dressed by the dresser can grind various triangular threads;
• The head spindle does not rotate, the workpiece depends on the disk drive, its rotation speed depends on the AC frequency conversion motor stepless adjustment, the adjustment range is very large, up to 5~200 r/min;
• The pitch of the grinding thread is 0.5mm. The rear end of the head frame is equipped with a correction ruler, which can correct the cumulative error and adjacent error of the pitch of the processed workpiece;
• This machine is dedicated to grinding screw with a pitch of 0.5mm micrometer.
