A thread grinding machine with a device for the relief grinding of the thread on tap drills and internal thread formers having straight or helically-shaped grooves or rolling edges, in which the rotating work-piece which is disposed coaxially with the axis of the work-piece spindle on the work-piece carriage, is guided past the grinding disk along the axial direction of the workpiece …

Many ground thread taps are produced by grinding from the solid after heat-treatment. Hardening high-speed steel taps before the thread is formed will ensure there are no narrow or delicate crests to interfere with the application of the high temperature required for uniform hardness and the best steel structure. Number of Wheel Passes

Six different processes can be used to produce micro threads: tapping, conventional turning, thread chasing, thread rolling, grinding and electrochemical grinding (ECG). Thread chasing and thread rolling are performed on lathes, with tools other than a conventional v-groove tool. Tapping

Unlike a tap, a thread mill has a smaller diameter than the thread size being produced because the mill must be able to enter into the drilled hole and interpolate. Thread milling provides excellent control of the thread's major diameter because it can be controlled using the machine's cutter compensation. Understanding Thread Mills

threads as shown in Fig. 7.1.2. Three taps namely, taper tap, plug tap and bottoming tap are used consecutively after drilling a tap size hole through which the taps are axially pushed helically with the help of a handle or wrench. Fig. 7.1.2 Hand operated taps for cutting internal threads.

Threading is the process of creating a screw thread.More screw threads are produced each year than any other machine element. There are many methods of generating threads, including subtractive methods (many kinds of thread cutting and grinding, as detailed below); deformative or transformative methods (rolling and forming; molding and casting); additive methods (such …

Grinding the rake of dies is more important in taper thread dies since in these dies the entire surface of the die is required to cut and will eventually dull. In bolt dies, only the teeth preceding the second full tooth are required to cut. As a result of this difference, bolt dies seldom require grinding on the rake face and then only slightly.
