Commonly used method in the grinding wheel thread following: ① wire wheel, vertical feed; ② gold wire wheel, vertical feed; (3) multi-line wheels, cut the feed. Three grinding characteristics are as follows:
 
A single line grinding wheel vertical feed grinding
 
This method is more convenient machine adjustment wheel dressing, small radial cutting force, the workpiece cooling conditions, high precision machining, grinding trapezoidal screw up to three (JB/T2886-1992) highest accuracy, surface roughness values 0.2-0.4 microns. Liter can grinding different thread angle, different teeth open a different aspect ratio of the workpiece, suitable for processing a variety of precision screw and ball screw, but productivity is lower than the multi-line grinding wheel, commonly used in the single-piece, small batch production.
 
2 multi-line grinding wheel vertical feed grinding
 
Also participate in cutting, due to the respective comb teeth of the cutting wheel and the grinding of the workpiece can be completed in a single pass, high production efficiency, but the the wheel dressing molding more difficult, and therefore a large pitch, helix angle of the thread and teeth the shaped high accuracy requirements threaded and should not be used, suitable for the a simple toothed grinding in mass production, lower precision threaded.
 
3 multi-line wheels cut feed grinding
 
This method is suitable for grinding pitch the small threaded liter angle, low accuracy and stubby threaded workpiece, and higher rigidity requirement of the the thread grinder's wheel spindle and workpiece clamping.
