The Acme and Buttress threads
Where to use the Acme & Buttress thread form, why
The Acme and Buttress threads are useful for the screw axis of a variety of assemblies. Specifically, for assemblies, it can effectively move load or precision. We can see some of the device’s screw axis; Yet most are hidden from view. Ascension, for example, tray, marking and marking machines, medical diagnosis and personal mobility, off-road equipment and machine tools, all need bearing or precise mobile, these devices can be through the use of equipment to provide a screw mechanism.
In general, the thread shape of the main screw is designed to provide high strength and accuracy. Acme is the most popular form of trapezoidal thread in the world. Although square threads are most effective, they are still difficult to generate. Because Acme 29 ° Angle is easy to produce, in both external and internal threads, it is cheap. They can be generated by multiple startup threads, left threads, and self-centering threads.
RL provides the standard size Acme faucet and creates many different dedicated taps, usually a rough trapezoid trapezoid. Our most popular style is “Unipass” Acme, which USES a tool’s thick and complete parts.
Trapezoidal threads are designed to handle extreme high – axial thrust in one direction. This is usually a 7 ° Angle 45 ° Angle weight surface and the rear side, it provides a good shear strength.
The ultimate high performance Tap
In many applications, hard alloy tools have replaced high speed steel. Because of the fixed feeding speed of the carbide, the carbide is not frequently selected. However, when the conditions are right, using the carbide tap can produce the maximum productivity, the excellent portion is completed, and the cost of each hole is low.
The RL carbide and carbon wrap are made of ultra-fine grain and high cobalt content binder. We can design a tap with high shear flute shape and strong support on the cutting edge to connect hard metal, inner hole and other hard metal.
