Thread Micrometer . Using a thread micrometer is the easiest way to accurately measure thread pitch diameter for comparison to the thread data listed in the Machinery Handbook or this link. However, thread mics are fairly expensive. Figure 6a: Example of a thread micrometer (notice the v-shaped anvils) and its use measuring thread pitch diameter.

Our Thread grinding wheels are formulated with high-performance, specially treated Aluminium Oxide grains combined with a special resin bond. The wheel is manufactured in a special process, which ensures excellent form retention of the wheel, which translates into a consistent thread profile of components.

Considering the grinding geometry of the thread grinding dynamic contact arc length, a dynamic numerical thread grinding model has been set up on the basis of study of a single grit grinding model. The properties of grinding force and dynamic contact arc-length have been studied by means of the developed numerical model.

The useful axial thickness of the grinding wheel is in the tooth space of the thread's normal section, meaning that the normal section of the thread profile in coordinate system S 2 can be calculated using Eq. and the following equation: (3) y 2 cos λ-z 2 sin λ = 0 where symbol λ is the lead angle of the thread. The normal thread profile can then be used to determine the axial …

THREAD GRINDING-Produce very accurate threads on hardened materials-Three basic methods are used. 1. Center type grinding with axis feed: (Work spins slower) similar to cutting thread in the lathe. difference a shaped grinding wheel is used instead of the point cutting tool.
