The single-line grinding wheel has a pitch accuracy with grades 5 ~ 6. It also has a surface roughness of R1.25～0.08 μm. Single-line grinding is ideal for making a precision screw, worm, thread gauge, shovel grinding hob, and small batch threading. The multi-line grinding is divided into cut-in and longitudinal grinding methods.

Machining is a manufacturing process that involves shaping or creating a part by removing material, typically metal, from a larger workpiece through cutting. This method is known as subtractive manufacturing, as it removes material to achieve the desired shape, unlike additive manufacturing, such as 3D , which adds material.

Honing is a method of internal grinding used to achieve a precise surface finish and shape on the inside diameter (ID) of a tube, bore, or hole. The honing and lapping processes are both highly controlled. Yet, where they are used and how they are accomplished are very different — and both methods have their own pros and cons.

A centerless grinding process uses abrasive cuts to remove material from a workpiece's outside diameter. Centerless grinding is different from traditional grinding because it does not require that the workpiece be mounted or fixed. The material can be removed quickly, producing a smooth and precise finish.
