Turning parts

Turning parts are a type of part that is processed using a lathe to produce products. By utilizing the rotational motion of the workpiece and the linear or curved motion of the cutting tool, the shape and size of the blank are changed to meet the requirements of the drawing. Turning machining is a method of cutting a workpiece on a lathe by rotating it relative to the tool. The cutting energy of turning machining is mainly provided by the workpiece rather than the tool. Turning is the most basic and common cutting method, occupying a very important position in production. Turning is suitable for machining rotating surfaces, and most workpieces with rotating surfaces can be machined using turning methods, such as inner and outer cylindrical surfaces, inner and outer conical surfaces, end faces, grooves, threads, and rotary forming surfaces. The main tools used are turning tools. The accuracy of turning processing is generally IT11-IT7, some can reach IT6, and the surface roughness Ra can reach 12.5-08um. The parts made by turning are called turning parts, and there are many types of turning parts, which are famous for maintaining the thermal stability of the parts through hard turning.

Screw

A screw is a tool that utilizes the physical and mathematical principles of the oblique circular rotation and friction of an object to gradually tighten the mechanical components of the object. Screws are a common term for fasteners, commonly used in everyday language. Screws are essential industrial necessities in daily life, such as tiny screws used in cameras, glasses, clocks, electronics, etc; General screws for television, electrical products, musical instruments, furniture, etc; As for engineering, construction, and bridges, large screws and nuts are used; Transportation equipment, airplanes, trams, cars, etc. are used with both large and small screws. Screws bear important tasks in industry, and as long as there is industry on Earth, the function of screws will always be important. The screw has been a common invention in people's production and life for thousands of years, and according to its application field, it is the first great invention of humanity.
