That means both of these internal grinding processes are limited in how small the diameter of the tube can be. Grinding may also be used on the cavities in cast parts, to eliminate the porous surface and get the desired final shape. Where the shape of the tube is more complex and convoluted, ID honing may be used. High-Pressure ID Honing

1) When internal grinding, the diameter of the internal grinding wheel is small, and the rotation speed of the grinding wheel is limited by the rotation speed of the internal grinding tools. Therefore, the grinding speed is usually within 20-30m/s. Due to the low grinding speed, the surface roughness of the workpiece is not easily reduced.

The skiving process is effective in reducing tooth distortions and noise. Especially useful in challenging component processing applications, where there is a shoulder close to the gear teeth by means of processing with a small diameter skiving hob, skive hobbing is an effective process solution where grinding may not be feasible.

The wheel used for grinding an internal bore on a piece of work is generally softer then that used for external grinding. This is mostly due to the comparatively large arc of contact between the work and the wheel. In addition the soft wheel cuts with little pressure and minimises the likelihood of springing the spindle.

The diameter of nozzles in aero engine is generally less than 1 mm. Because of the smaller diameter of the grinding wheel used, its stiffness is poor and thus the wheel tends to deflect under the grinding force. The deflection of grinding wheel has great influence on the actual feed, which ultimately affects the roughness.

if the diameter of the grinding wheel is too small, it is difficult to achieve the ideal grinding speed (30m/s~50m/s), which increases the grinding thickness, increases the conformity of the grinding grains, and is easy to blunt, which increases the surface roughness of the inner hole and reduces the production efficiency when grinding the hole .

1. Introduction. A number of problems occur in the process of internal cylindrical grinding, which result from the process' kinematics. The most important impediment is the very long area of contact between the grinding wheel and the machined material, often caused by the minor difference between the grinding wheel and the ground opening's diameters.
