Thread Machining Machine Specialized machine tools for machining threads (including worms, hobs, etc.). Mainly used in the manufacturing of machinery, cutting tools, measuring tools, standard parts and household appliances. The application of the thread principle can be traced back to the spiral water lifting tool created by Archimedes in Greece in 220 BC. Around 1500, in the sketch of the thread processing device drawn by Da Vinci of Italy, the idea of ​​machining different pitch threads with the mother screw and the exchange gear has been applied. In 1760, the British F. Wyatt brothers obtained a patent for a special device for cutting wood screws. In 1778, J. Ramsden of the United States produced a thread cutting machine with a worm gear drive. In 1797, H. Mozley of the United Kingdom produced a threaded lathe that used a female screw and an exchange gear to turn different threads. In the 1920s, Mozli produced taps and dies for threading. After the 20th century, various thread processing machines were introduced. Thread processing machines can be divided into: 1 thread cutting machine according to the method of machining threads. Such as thread turning lathes, thread milling machines, thread grinders, tapping machines, threading machines, etc., where thread turning machines, thread milling machines and thread grinders use thread processing tools or grinding wheels to machine threaded workpieces of various precisions, thread cutters and thread gauges. The wire machine and the Threading machine are respectively processed into mass-produced nuts and screws by specially designed taps and wrenches; 2 thread rolling machines. The workpiece is plastically deformed by a forming rolling die to obtain threads, such as a thread rolling machine, a thread rolling machine, etc., and has high productivity, and is suitable for mass production of a large number of external threads of standard fasteners and other threaded couplings.
The performance of the machine tool adopts the large-span spindle box structure, which improves the spindle bearing arrangement of the spindle head box and increases the rigidity of the box body. The specification of the main guide rail is increased, the strength of the whole machine, the dynamic and static rigidity, and the mechanical parts of the main components are improved. The structure is reasonable, it is a full-function CNC pipe thread lathe with high rigidity, high precision and good precision retention. It has high production efficiency, good operation and pleasant appearance, beautiful appearance and anti-three leakage effect. This machine is equipped with FANUC numerical control system. It is a special CNC lathe specially used for thread processing of oil casing. The outer diameter of machining external thread is in the range of φ 110 — φ 340mm. The buckle type of machining taper thread includes circular buckle and partial Trapezoidal buckle and other special button shapes.

Hastelloy is the prefix name of a family of alloys. Nickel is typically the base alloy, and other ingredients (such as molybdenum, chromium, cobalt, iron, titanium, aluminum and tungsten) are added to the base in varying percentages.
Hastelloy is corrosion resistant and used in high-temperature, high stress environments, such as the aerospace, chemical processing and power generation industries. It has outstanding stress corrosion cracking resistance and resistance to non-oxidizing acids (such as hydrochloric and sulfuric acid).
